PRE-DELIVERY SERVICE OF MOWER BY DEALER

Before proceeding with the Pre-Delivery Service of your mower, please read the safety instructions manual in its entirety. Only your authorized

WARNING

Wright dealer should perform the Pre-Delivery Service of the mower.

The Wright Stander is shipped completely assembled and has been adjusted and tested at the factory.

However, due to the jostling of the shipping process and the delivery time lapse, the following items need to be repeated again before starting the mower. After you have uncrated the mower, follow these procedures in the order indicated:

Inspect the mower for any damage, unusual conditions or missing parts.

Inspect the mower for all of its decals, especially the warning decals. There should be one blade warning decal on each side of the deck, the “shield missing” decal under the blade belt cover, and the dash decal.

Check service, parts and recall bulletins to ensure unit does not need any updates.

Check (and fill if necessary) engine oil level according to the engine manufacturer’s recommendation.

Check (and fill if necessary) hydraulic fluid level. Use fully SYNTHETIC oil: Mobil-1 15W-50 (see Hydro

Check/Fill section of this manual).

Check rear tire pressure – 18 – 22 psi. is recommended. Use the higher pressures for heavier operators.

Front Casters are equipped with non-pneumatic tires and do not require any air. Lowering tire pressure will

affect deck pitch. Always check pitch any time tire pressure is set below recommended pressures.

Lubricate all appropriate moving parts (see the Lubrication section of this manual).

Check the battery to see that the cables are tight and connected properly. The battery is 12 volts and is a maintenance-free battery. Only charge the battery if it will not start the mower properly.

Add regular unleaded gasoline to fuel tank. (use a minimum of 87 octane gasoline) (You may use gasoline containing up to 10% ethanol and gasoline containing up to 5% of methanol.)

Check brake safety interlock.

Try starting the engine with the parking brake released. (Engine should not start. If engine starts, service the parking brake locking system)

Apply parking brake

Start the engine according to the engine manufacturer’s recommendation. Let the engine run at low - mid

RPM for several minutes to ensure the engine oil reaches all of the engine parts and gets the hydraulic fluid circulating through the pumps, etc.

Check if the parking brake locking system prevents the units from being driven while engaged. If not, service the parking brake locking system.

Release the parking brake. Next, move the hand control levers, one at a time, to make the wheels move in forward and backward rotation.

Before testing the blade clutch/brake operation, make sure the area is clear and there is nothing vulnerable to possible thrown objects from under the mower. No one should be near the mower deck or in its line of discharge at this or at any time. The discharge chute deflector should be in the down position.

Move the engine throttle control to ¾ RPM speed setting.

4

Turn on the blade clutch switch. Run blades for approximately one minute. Next, engage and disengage the blades a few times about 10 seconds apart. If the blades do not start and stop in a few seconds each time, service the blade brake system.

With the blades on, disengage the OPC switch to test the Operator Presence Control switch (OPC). A time delay has been added to the OPC system. The engine should die and the blades should stop with-in

6-9 seconds after stepping off of the foot platform. If not, service the OPC system.

Disengage the blades.

Drive the mower around on a level parking lot. Check that the mower drives in a straight line when both hand controls are at the full speed position. (If not, refer to How to Perform The Tracking Adjustment section of this manual) (The control handles may not line up perfectly)

As you drive the mower, listen for any unusual noises and test for irregular operation and adjust or service as necessary.

Go over the safety information and operating procedures in this manual with the customer. Instruct each customer in proper operation and observe the customer during their initial operation on a level parking lot.

Repeat until the customer is familiar and comfortable with the basic operation and use of the mower.

•

WARNING

DO NOT operate the mower while wearing sandals, tennis shoes, sneakers, or shorts. Always wear long nonbaggy pants. Wear high-top leather steel-toed work boots with thick, textured tread, soft-rubber soled at all times. Hard or smooth soled shoes are too slippery for a good footing on mower platform. NEVER wear loose-fitting clothing or jacket pockets that can get caught on the handlebars or control levers of any mower you drive. Wearing safety glasses, ear protection and safety shoes is advisable and required by some local ordinances and insurance regulations.

1.8 Inspect the Mower Before Each Use

WARNING

DO NOT use the mower if any parts are not maintained in good operating condition. Examine the moving parts prior to each use. Look for excessive wear, bald or worn tires, cracks in parts, loose or missing bolts, cotter pins, linchpins and replace before operating the mower. Make sure all safety equipment provided with the mower is in good operating order, including all the warning decals and the required operator-presence device which stops the engine and blades when the foot-operated Operator Presence Control (OPC) switch is released. (To test the OPC, follow instructions in the Operating Instructions section of this manual.) Inspect the two anti-tip rollers and their respective bolts at the rear of the mower for tightness and proper operation.

Be sure that all parts of the hand-operated hydraulic control system are tight and secure. This is to reduce the possibility that the mower could have a loss of control during operation and compromise operator safety.

1.9 Regular Mower Safety

WARNING

Keep your Wright mower in good operating condition, and keep safety devices and shields in place and in working condition. Replace worn tire(s) with less than 3/32” of any tread groove left. Use tires with the tread pattern specified by Wright Mfg., Inc. only. DO NOT change the engine governor settings or over-rev the engine contrary to engine manufacturer specifications. Failure to comply can compromise operator safety, shorten equipment life and void your manufacturer’s warranty. Keep all nuts, bolts, and screws tight to be sure the equipment is in safe working condition. Check the blade mounting bolts for proper tightness every eight (8) hours of operation. Check the blades for excessive wear and sharpness every four to eight (4-8) hours of operation. Sharpen dull blades. Replace blades when they become excessively worn. The mower should not be used after the blades or other part of the mower strikes a foreign object, until conducting a thorough inspection and any damage is repaired. When inspecting or changing blades, turn off the blade

clutch switch, apply the parking brake, stop the engine and remove the key. Make sure the chute deflector is always in place and operating properly. Replace if the deflector becomes worn or ceases to properly deflect the grass in a safe manner. (Refer to the maintenance interval chart at the end of this manual)

8

1.10 Prevent Fires

WARNING

Machine fires and structural fires can occur if a machine is stored before allowing it to cool, if debris is not removed from critical areas of the machine, or if the machine is stored near combustible materials.

•

Remove grass and debris completely from engine compartment and muffler area, and from on top of the

mower deck, before and after operating machine, especially after mowing or mulching in dry conditions.

•

Always shut off fuel when storing or transporting.

•

Do not store near an open flame or source of ignition, such as a water heater or furnace.

•

Check fuel lines, tank, cap and fittings frequently for cracks or leaks. Replace immediately if necessary.

1.11 Work Area Conditions and Inspection

WARNING

Prior to operating the unit, carefully inspect all lawn/ground areas where you plan to use the mower for hidden, hard-to-see objects or uneven ground that may be hidden in the grass. Clear the work area of moveable objects such as wires, rocks, glass, toys, etc. that might be picked up by the mower and dangerously thrown.

Remove, if possible, or mark the location of all immovable objects or irregular areas and be sure not to hit them with any part of the mower, its deck or the blades. Obstacles such as holes, abrupt changes in ground contour, tree trunks, stumps or roots, pipes protruding from the ground, paving edges, etc. in the path of operation can abruptly turn or stop the mower. This could throw you off the mower or into and possibly over the handle bars causing serious injury or death. The faster you are moving the more potential there is for injury. Mow only in daylight or in good artificial light. Keep away from drop-offs, the edges of ponds, streams, pools, etc. especially at the bottom of slopes. Do not mow when children or others are around. When the

Wright mower is in use, never direct the grass discharge toward bystanders, traffic, cars or buildings nor allow anyone within 50 feet of the machine while in operation. Thrown objects can pass through glass windows and some walls of buildings. There is extreme risk of danger from thrown objects or being cut by the blades of the mower or being run over if you lose control. Never operate the mower in an enclosed area without good, approved ventilation. Exhaust fumes are dangerous.

1.12 Initial Operating Safety Guidelines

WARNING

•

Read and understand the warnings on the instrument panel of the mower.

•

Regularly check and test the safety devices for correct function.

•

Recommended PPE is safety shoes, safety glasses and ear protection.

•

Keep a firm hold on the stationary handle at all times.

•

Keep both feet on the foot platform at all times.

•

Know the controls and how to stop quickly.

•

Before attempting to start the engine, follow all starting instructions below and in the engine operator’s manual.

•

Look behind before backing up.

•

Before leaving the operator’s position, even momentarily, turn off the blade clutch engagement switch and apply the parking brake. Keep others from coming near the mower. Get back on the mower as soon as possible.

•

When leaving the Wright mower unattended, turn off the blade clutch engagement switch, apply the parking brake, stop the engine and remove the key. Never leave the machine unattended on a slope in case someone disengages the parking brake. This could create a rollover hazard.

•

When transporting, driving onto transport vehicles, into buildings, across parking lots or otherwise not mowing grass, turn off the blade clutch engagement switch to reduce risk of thrown objects and rotating blade hazard. After coming to a stop apply the parking brake, stop the engine and remove the key.

•

Before performing any maintenance or repair service, disengage power to blades, apply the parking brake, stop the engine, remove ignition key and spark plug wire from spark plug(s).

•

All operators of this mower should exercise caution when driving this mower at high speeds. Sudden acceleration or deceleration may cause serious injury.

•

Do not allow inexperienced persons to operate the mower until they have read and understood these safety instructions. Operate the mower at slower speeds while becoming familiar with it.

9

•

The grass discharge chute deflector must be installed at all times and in the down position except that it may be raised when cleaning out the deck or a grass catcher is installed or a mulch kit and block-off plate is properly installed.

•

If the mower discharges grass clogs, turn off the blade clutch switch, apply the parking brake, stop the engine and remove the key before removing obstruction(s).

•

Keep all shields and covers in place, namely, all blade and belt covers, engine shields, and grass discharge chute deflector.

•

Keep hands, feet and clothing away from rotating parts, especially the rear wheels, blades, engine flywheel, belts and pulleys.

•

Do not touch engine, muffler or hydraulic system while engine is running or soon after it is stopped. These areas can be so hot as to cause severe burns.

•

Clean grass, leaves and lubricant spills from surfaces after use to prevent fire hazard.

•

Be alert for traffic when crossing roads or operating near roadways.

•

Before climbing curbs, crossing gravel drives, sidewalks or roads, turn off the blades and wait for them to stop.

1.13 Safety for Maintenance

WARNING

•

Repairs carried out by untrained or unauthorized personnel may result in personal injury or serious malfunction of the Stander.

•

If Guarding is removed for inspection and component replacement, ensure the parking brake is applied and key is removed prior to inspecting or making repairs and that the guarding is replaced before operation.

1.14 Operation in Forward Direction

WARNING

Always keep a firm grip on the mower stationary handlebar with both hands. Operate the mower slowly until you become familiar with how the mower operates. Do not operate the mower faster than conditions allow.

For example, hills, wet or bumpy ground, dim light or high grass are all conditions requiring slower speeds.

Never operate the mower at the highest speed unless you are on level, wide, open areas of clearly visible ground or transporting on paved areas. Speeding with any mower is dangerous, and so is traveling faster than conditions should permit on this mower. Sudden stops from excessive speed or falling off the mower may cause serious injury or death.

1.15 Operation in Reverse

WARNING

Always keep a firm grip on the mower stationary handlebar with both hands. Keep both feet firmly on the foot platform. Look behind you before backing to prevent injuring yourself or anyone behind you. Operate the mower very slowly, inching it backward until you become familiar with how the mower operates. Always operate slowly if in an awkward location or position. While backing up never place your foot or feet on the ground near the back edge of the mower to prevent serious personal injury if the mower were to run over you.

1.16 Zero-Radius Turn Operation

WARNING

During zero-radius turns (when one mower wheel rotates backwards while the other rotates forward) drive extra slowly to reduce the possibility of losing traction, or control, or becoming dizzy. This will help prevent you from being thrown off the mower. Be aware that if you do a turn on a slope you may go through all of the orientations to a slope mentioned below and must handle the mower accordingly.

1.17 Operation on Slopes

WARNING

DO NOT operate on steep slopes for long periods or engine damage may occur. (Refer to Engine manual)

Do not operate the mower on slopes steeper than you can feel secure about the traction of the tires and the stability of the mower. Do not operate the mower on slopes at all when the grass is wet. There is a danger of

10

suddenly sliding sideways or down the hill. When operating on a slope, travel across the grade whenever possible, not in an up or down pattern. Reduce speed and exercise extreme caution on slopes and in sharp turns to prevent tipping or loss of control. Be especially cautious when changing direction on slopes.

When pointing up a slope, your mower has the most weight on the drive wheels and therefore the most traction at the tires. However, this is the angle that it has the most tendency to tip back (“pop a wheelie.”) This is the preferred angle for mowing small areas of steeper slopes.

Recommendations for this angle:

•

Lean as far forward as possible to add your weight to the front of the mower.

•

Accelerate gently. Do not accelerate quickly to avoid “popping a wheelie”.

•

If backing down the hill, do not stop suddenly but slow down gradually.

When pointing down a slope, your mower has the least weight on the rear drive wheels and therefore the least traction at the tires. This is the angle that the mower has the most tendency to slide. However, this is the angle that it has the least tendency to tip back. Avoid this angle, as it has the least advantage for your mower.

Recommendations for this angle:

•

Lean back with arms stretched out straight while holding onto the stationary handlebar. This transfers more of your body weight to the rear drive wheels for more traction.

•

Do not change speed suddenly to minimize the tendency of going into a slide. Accelerate and decelerate gently. If you ever go into an uncontrolled slide while pointing down a slope the recommended procedure is to let go of the handles and jump off if necessary. Otherwise, control the mower gently and stay off slopes that tend to make the wheels slide.

When crossing a slope sideways, your mower has the average amount of weight on the drive wheels versus the front wheels, similar to level ground. However, this angle leaves the least weight on the higher side drive wheel, tending to make it slip. This is the preferred angle for mowing large areas of gentle slopes.

Recommendations for this angle:

Lean back and angle your body to the upper side of the mower. This adds weight to the rear drive wheels and will allow you to mow more quickly across the slope without sliding. These are general guidelines only. The mower function and comfort will vary depending on mowing environment, operator driving style and preference.

•

To reduce the chances of “popping-a-wheelie”, do not accelerate quickly.

Note: Excessively worn tire tread is dangerous. Replace tire(s) with less than 3/32” of any tread groove left.

Use tires with the tread pattern recommended by Wright Mfg., Inc. only. Keep the tire pressure in the drive tires between 18 and 22 psi. Higher pressures will cause the tires to have less traction which may prevent safe operation. Lower pressure will affect the deck pitch, thus creating a level deck or a reverse pitched deck

and this WILL compromise cut quality. (Refer to tire maintenance and pressure section)

1.18 Fuel Safety

WARNING

Handle gasoline with care – it is highly flammable. Do not smoke while handling gasoline. Use an approved gasoline container. Never remove the fuel cap or add gasoline to a running or hot engine or an engine that has not been allowed to cool for several minutes after running. Never fill the tank indoors and always clean up spilled gas. NEVER store the equipment with gasoline in the tank inside a building where fumes may reach an open flame or spark.

Allow the engine to cool before storing in any enclosure.

1.19 Using a Spark Arrester

The engine in this machine is not equipped with a spark arrester muffler. It is in violation of California Public

Resources Code Section 4442 to use or operate the engine on or near any forest-covered, brush-covered, or grass covered land unless the exhaust system is equipped with a spark arrester meeting any applicable local or state laws. Other states or federal area may have similar laws.

1.20 Hydraulic Safety

WARNING

Keep body and hands away from pin holes or fittings that eject hydraulic fluid under high pressure. Use paper or cardboard and not hands to search for leaks. Hydraulic fluid escape under high pressure may have sufficient force to penetrate skin and cause serious injury. If foreign fluid is injected into the skin, it must be surgically removed within a few hours by a doctor familiar with this form of injury or gangrene may result.

Seek medical attention immediately. Make sure all hydraulic fluid connections are tight and all hydraulic hoses and lines are in good condition before starting your Wright mower. Hydraulic fluid is under high pressure. If you need service on your hydraulic system, please see your authorized Wright dealer.

5 Operating Instructions

If you are not completely familiar with the Safety Instruction Manual read

WARNING

it now before proceeding with the operation of the mower. REMEMBER

THERE ARE CERTAIN PRECAUTIONS LISTED IN THIS MANUAL THAT

YOU MUST NOW TAKE BEFORE STARTING THE MOWER.

5.1 Inspect Mower Before Each Use

Inspection of Mower: Do not use the mower if any parts are not maintained in good operating condition.

Examine all moving parts prior to each use. Look for excessive wear, bald drive tires or worn out front tires

(normally smooth), cracks in parts, loose or missing bolts, cotter, linchpin or “hair” pins or cable yoke pins and replace before operating the mower. Make sure all safety equipment provided with the mower is in good operating order, including all warning decals and the operator-presence device which stops the engine and blades when the foot-operated Operator Presence Control (OPC) switch is released. To test the OPC, follow the instructions given later in this manual. Inspect the two anti-tip rollers and their respective bolts at the rear of the mower for tightness and proper operation. Ensure that all parts of the Quad-Lever™ control system are tight and secure. This is to reduce the possibility that the mower could have a loss of control or safety.

Basic Operation: The following procedures are to guide you through the basic operation of the mower. You should be a qualified mower operator according to the safety section of this manual. If this is your first time, operation should only be done with the assistance of your dealer on a level area. You should go through each step, in the order indicated, every time you start the mower.

5.2 How to Start the Mower

Before starting the engine

•

Move mower to an open, well ventilated area.

•

Make sure the control levers are in the exact neutral position.

•

Apply the parking brake if it is not already set.

•

Turn OFF the blade engaging switch if it is on.

•

Check the engine oil.

•

Turn fuel valve to the “ON” position.

Starting the engine

• Start the engine according to the engine manufacturer’s recommendation, see engine manual. Set the throttle control lever near mid throttle, pull out on the choke control knob and turn the key to the start position. Do not engage the starter for more than ten (10) seconds at a time. This may overheat the starter and the wiring systems. Wait ten (10) seconds between attempts. If the engine does not start after several attempts or stalls frequently, take the mower in for service.

After starting the engine according to the engine manufacturer’s recommendation, push in on the choke control knob to open the choke valve, let the engine run for several minutes to get the hydraulic fluid circulating through the pumps, etc. and to allow the engine to warm up. Do not over-rev a cold engine.

Unusual noises or irregular operation:

As the engine is warming, listen for any unusual noises and test for irregular operation and adjust or service as necessary.

5.3 How to Drive the Mower

WARNING

While standing, both feet should be firmly placed on the foot platform. Set the engine speed about a fourth of the way from idle. Release the parking brake. Now try moving the hand control levers, one at a time, very slightly, forward and backward. Check to see if the wheels move forward and backward according to the position of the levers. If not, check to see that the pump release valves are closed. With both feet still firmly placed on the foot platform, increase the engine speed to about half of the way from idle speed. Release the parking brake. The higher engine speed will make the controls much more responsive and the mower much quicker; Use caution if it is your first time. Now try moving the hand control levers, one at a time, very slightly,

5.7 How to Adjust Neutral

Neutral refers to the mower movement when the engine is set to full throttle, parking brake is off, and the control levers are in the neutral position. The mower should not move forward or backward during this time. If the mower is moving forward or rearward, the neutral setting must be adjusted. The hydraulic pump has a Return-to-Neutral (RTN) device built into the linkage of the pump. Before adjusting neutral, it is necessary to lift the rear drive wheels off the ground using a jack and stands. To make the adjustment, loosen the ¼” Allen bolt (A) and rotate the RTN device on the pump corresponding to the wheel that needs adjustment. If the right wheel turns in the neutral position, then the right pump RTN needs to be adjusted. The RTN mechanism should be rotated until the neutral position is found and then retighten the ¼” allen bolt. Use care not to over tighten the allen bolt. Repeat the procedure on the other pump if necessary.

5.8 Changing the Speed/Sensitivity Adjustment

The controls are initially set with the Speed/Sensitivity Adjustment in the faster, more sensitive position. If an operator is not completely familiar with the mower operation the operator may desire to decrease the ground speed. The slower setting has a corresponding decrease in the sensitivity of the controls. In other words, a given amount of movement of the control levers will cause about a 25-30% change in the ground speed making the controls less sensitive. After stopping the engine, the adjustment is made by removing rod ends from the current holes in the pump levers and reinstalling them into the alternate holes.

The holes farthest from the operator position are for the faster, more sensitive setting and the holes closest to the operators position are the slower, less sensitive setting. You must then perform the Tracking Adjustment described below.

Slow Hole

A

5.9 How to Perform the Tracking Adjustment

WARNING

First ensure that the tire pressure is equal on both rear drive tires (18-22 psi). Drive the mower on a level parking lot with the engine at full throttle. Check that the mower drives in a straight line when both hand controls are held to the full speed position. If not, park the mower and stop the engine. The adjustment is made by loosening the jam-nuts on the control rods (this may need to be done to one or both control rods) and adjusting the control rods. Once the jam-nuts are loosened at the top and bottom of the control rod proceed to turning the control rod clockwise or counter-clockwise. Shortening the control rod will increase the speed of the forward movement of the mower on that side. Lengthening the control rod will slow the forward movement of the mower on that side.

22

In the “faster” Speed/Sensitivity setting (this is the factory setting) neither rod should be lengthened so much that at full speed it pulls the pump control lever (on the sides of the pumps) against the internal pump stop.

Therefore, to reach the maximum capable speed, the rods should be lengthened one turn at a time until you can feel, in the hand control, that the internal pump stop has been contacted. Then shorten the rod one turn

(damage to the hydro pump will occur if the controls are adjusted in a way that put direct pressure on the internal pump stop). You will feel the slight resistance. There is no need to start the engine while checking this incrementally. Remember, this procedure does not apply if the Speed/ Sensitivity Adjustment is in the slower setting.

If the rod is made shorter it will increase the forward speed capability for that side of the mower and if the rod is made longer it will slow down that side of the mower. So, if the mower is tracking to the left, either the left side needs to go faster (by shortening the left-side rod) or the right side needs to go slower (by lengthening the right-side rod). If the mower is tracking to the right, either the right side needs to go faster (by shortening the right-side rod) or the left side needs to go slower (by lengthening the left-side rod). It is important that neither rod should be shortened too far, as mentioned above.

The only reference point to limit the adjustment from becoming extremely off is the relative position of the pump stop and the handlebar in the faster Speed/Sensitivity setting. Therefore, if everything is way off either because you are installing new parts (or other reasons) you should only use the faster Speed/ Sensitivity

setting to get the tracking accurate and then change to the slower speed range and adjust the tracking only one or two turns on either side.

After getting the mower to track straight, check and/or readjust the neutral adjustment on the pump by using a

¼” allen wrench at the Return-to-Neutral (RTN) mechanism, if necessary. It is normal to make these adjustments from time to time.

5.10 How to Test/Use the Blade Clutch/Brake Switch

WARNING

Before testing the blade clutch/brake operation, make sure the area is clear and there is nothing vulnerable to thrown objects from under the mower. No one should be near the mower deck or in its line of discharge. The discharge chute deflector should be in the down position. Move the engine throttle to ¾ speed setting. When mowing, the engine speed should always be at its highest setting. The engine governor will regulate the engine according to the different mowing conditions at that setting. Place both feet firmly on the foot platform and turn on the blade clutch switch. Run blades for a minute or so. Try engaging and disengaging the blades a few times about 10 seconds apart. If the blades do not start and stop in 6-9 seconds each time, service the blade brake system or contact your local Wright dealer. Under mowing load, the clutch’s life will be the greatest if engaged and disengaged at the ¾ throttle level.

5.11 How to Test the Operator Presence Control (OPC) Switch

A three second time delay was added to eliminate clutch cycling on bumpy terrain.

To test, apply the parking brake and turn ON the blades, try lifting your feet off the foot platform to test the Operator Presence Control switch (OPC). The engine should kill and the blades should stop within 6-9 seconds. If not, service the OPC system or contact your local Wright dealer.

6 Service and Adjustments

WARNING

6.1 Tire Maintenance and Pressure

Excessively worn tire tread is dangerous on all hills. Replace drive tires with less than 3/32” of any tread groove left. Use tires with the tread pattern recommended by Wright Mfg., Inc. only. Keep the tire pressure in the drive tires between 18 and 22 psi. Higher pressures will cause the tires to have less traction, which will force you to go slower and with less safety and give you a harder ride. Front Casters are equipped with nonpneumatic tires and do not required any air. They do not have any tread but should be replaced when excessively worn. Lowering the tire pressure below the recommended pressure will change the pitch of the deck which may require further deck pitch adjustment.

6.2 Height-of-Cut

Before Adjusting the Height-of-Cut be sure of proper air pressure in rear drive tires and check for even tire wear. Your mower is set from the factory at 3” with a ¼” forward pitch. The height-of-cut can be adjusted the following ways:

1. Coarse Adjustment: For the coarse adjustment (1/2 inch increments) the rear motor supports (A) and (1 inch increments) front caster arms (B) need to be adjusted up or down to achieve a 1.5”-5” deck height.

2. Fine Adjustments: For fine adjustments (1/16”-1/4”) adjust either the ¼” blade spacers, ¼” caster “C” spacers (C) or 1/16” caster washer (D).

3. Temporary Height-of-Cut Adjustment: using the caster shims ("C" spacers) you can adjust the blades downward

NOTE: Ensure clutch stop is reinstalled.

25

6.4 Spring platform Adjustment

The factory setting is both springs set at the most forward position. The more rearward the spring position, the stiffer the platform gets. Adjustment will be to preference of feel. The two adjustment springs should at all times, be positioned next to each other not one forward or back more than the other. To adjust, loosen each spring retaining bolt from the top just enough to slide it, then tighten with impact wrench. The nut may spin using hand wrench. NOTE, do not loosen too much, if the nut falls off, the foot platform will have to be removed to reinstall. There is an extra hole for a third spring for operators heavy enough to bottom out the duel spring stock set up.

6.5 Hydraulic System

OFF ON

Whenever servicing the hydraulic system, it is of the utmost importance to keep any dirt or debris from getting into the system. Clean off all parts before disassembly and assembly. When any of the hydraulic parts are disconnected or removed or when the oil is changed, air must be bled from the system. If air is entrained in the system, loss of power, excessive heat, and damage to the hydraulic pumps may occur.

6.7 Bleeding Air from the Hydraulic System

Whenever servicing the hydraulic system, it is of the utmost importance to keep any dirt or debris from getting

into the system. Clean off all parts before disassembly and assembly. When any of the hydraulic parts are disconnected or removed or when the oil is changed, air must be bled from the system. If air is entrained in the system, loss of power, excessive heat, and damage to the hydraulic pumps may occur. First, make sure the oil level in the reservoir is correct. The oil should be level with the bottom threads of the oil level port. Use fully synthetic oil: Mobil1 15W-50. With the bypass valves open and the engine running, slowly move the control levers back and forth five or six times. Now close the bypass valves and with the engine running, slowly move the control levers back and forth five or six times. It may be necessary to repeat the above steps until all the air is purged and the rear wheels are turning at normal speed. After purging is complete, adjust the oil level in the reservoir if necessary.

6.8 How to Move the Mower if the Engine Won’t Start

Rotate both of the hydro bypass valve levers on the side of each hydraulic pump about ½ turn counterclockwise. It is important not to over tighten these levers. Damage may occur to the pump if this valve is over tightened.

6.9 Lubrication

Grease with No. 2 general purpose lithium base or molybdenum base grease.

•

Set parking brake, stop the engine and remove the key.

•

Clean grease fittings with a rag.

•

Connect grease gun to fitting and pump until grease begins to ooze out

Caster

Arms/Pins from the bearings.

•

Wipe off excess grease.

•

Do not use spray lube of any kind on choke and/or throttle cables.

6.12 Transporting

Use a heavy duty trailer or truck to transport the Stander. Lock brake and block wheels. Securely fasten the unit to the trailer or truck with straps, chains, cable or ropes.

28

6.13 Tie Down Locations

Use metal tie down bars in the front and anti tip wheels in rear to securely fasten unit to the trailer or truck with straps.

6.14 Loading and Unloading

WARNING

Use extreme caution when loading and unloading units on/off trailers or trucks. One full width ramp that extends beyond the rear tires is recommended rather than individual ramps for each side of the unit. The ramp should be long enough so that the angles between the ramp and the trailer or truck does not exceed 15 degrees. A steeper angle may cause the mower deck components to get caught as the unit moves from ramp to trailer or truck. Always put the deck in the transport (up & locked) position when loading or unloading. Never attempt to turn the mower around on the ramp. Avoid sudden acceleration when driving up a ramp and sudden deceleration when backing down a ramp.

6.15 Cleaning the Mower

The underside of the mower deck should be checked and cleaned twice daily and more often if the grass

being mowed is lush or wet. The entire mower should be cleaned daily at the end of the work day.

Cleaning should be done with a leaf blower or low-pressure compressed air. Wash with water only when necessary and do not use a pressure washer or nozzle as the water can enter bearings and electrical connections causing an electrical short, rust and corrosion. When washing with water, avoid spraying near the hydro cap and do so when the unit has cooled down. Washing a hot machine can cause various unseen system damage. If water is used for cleaning, immediately dry it with a leaf blower or low-pressure compressed air and run with blades engaged for approximately 10 minutes. Once the wash is complete, always lubricate and grease all applicable areas.

29

6.16 Spindle and Drive Pulley Split hub R&R

•

Remove 2, ¼” bolts from split hub and install in threaded holes in hub.

•

Slowly tighten each bolt, alternating as you tighten bolts against the pulley.

•

The hub will separate from the pulley.

6.17 Cutting Blades

WARNING

In order to maintain the best cut, it is important that the blades are well sharpened and not damaged. Bent or cracked blades or blades with large nicks need to be replaced. Blades must be balanced after sharpening. To change the blades:

•

Stop engine, remove the key and wait for all moving parts to stop.

•

Engage the parking brake

•

Lift front of mower and secure in the raised position with jack stands.

•

Remove the blade nut by turning counterclockwise.

•

Any part of the

WMI commercial mower found, in the reasonable judgment of WMI, to be defective in materials or workmanship, will be repaired or replaced by an

Authorized WMI Service Dealer without charge for parts and (except as excluded below) labor. This Warranty is transferrable with its remaining conditions to legitimate successor Owners to the original retail purchaser/owner.

Dealer demo units with less than fifty hours when first retailed shall also be covered by this limited warranty. Proofs of Purchase will be required by the

Authorized WMI Service Dealer to substantiate any warranty claims. All WMI warranty work must be performed by an Authorized WMI Service Dealer and mower must be delivered to the dealer prior to the expiration of the warranty period. This Warranty is limited to the following specified periods from the date of the original retail purchase for defects in materials or workmanship and will commence upon the date of original retail purchase.

Authorized WMI Service Dealer and reflects the actual date of original retail purchase. This warranty includes only the cost of parts and labor (when applicable).

Other conditions:

The WMI mower, including any defective part, must be returned to an

Authorized WMI Service Dealer within the warranty period. The expense of lost production time and delivering the mower to the Authorized WMI Service Dealer for warranty work and the expense of returning it to the Owner after repair will be paid for by the Owner. WMI’s responsibility is limited to making the required repairs and no claim of breach of warranty shall be cause for cancellation or rescission of the contract of sale of any WMI mower. This Warranty does not cover any mower that has been subject to misuse, neglect, negligence, burning in any fire, flooded by water, damaged in an accident, or that has been operated or maintained in any way contrary to the operating and maintenance instructions as specified in the Owner’s Manual. The Warranty does not apply to any damage to the mower that is the result of improper maintenance or to any mower or parts that have not been assembled or installed as specified in the

Owner’s Manual. The Warranty does not cover any mower that has been altered or modified changing performance or durability. In addition, the Warranty does not extend to repairs made necessary by normal wear, or by the use of parts or accessories which, in the reasonable judgment of WMI, are either incompatible with the WMI mower or adversely affect its operation, performance or durability.

WMI reserves the right to change or improve the design of any mower without assuming any obligation to modify any mower previously manufactured.

This warranty applies only to the replacement of defective or otherwise warrantable WMI OEM parts being replaced with WMI OEM parts.

WMI’s obligation under this Warranty is strictly limited to the repair or replacement of defective parts and WMI does not assume, or authorize anyone to assume for them, any other obligation.

FEDERAL AND CALIFORNIA EMISSION CONTROL WARRANTY STATEMENT

YOUR WARRANTY RIGHTS AND OBLIGATIONS

The United States Environmental Protection Agency (EPA), California Air Resources Board (CARB) and

Wright Manufacturing, Inc. (WMI) are pleased to explain the evaporative emission control system (EECS) warranty on your 2013 - 2014 commercial mower. In the United States, new equipment that use small off-road engines must be designed, built and equipped to meet the Federal’s stringent evaporative emissions standards. In California, new equipment that use small off-road engines must be designed, built and equipped to meet the State’s stringent anti-smog standards. WMI must warrant the EECS on your commercial mower for the period of time listed below provided there has been no abuse, neglect or improper maintenance of your equipment.

Your EECS may include parts such as the carburetor, fuel-injection system, the ignition system, catalytic converter, fuel tanks, fuel lines, fuel caps, valves, canisters, filters, vapor hoses, clamps, connectors, and other associated emission-related components.

Where a warrantable condition exists, WMI will repair your commercial mower at no cost to you including diagnosis, parts and labor.

MANUFACTURER’S WARRANTY COVERAGE:

This evaporative emission control system is warranted for two years. If any evaporative emission-related part on your equipment is defective, the part will be repaired or replaced by WMI.

OWNER’S WARRANTY RESPONSIBILITIES:

• As the commercial mower owner, you are responsible for performance of the required maintenance listed in your owner’s manual. WMI recommends that you retain all receipts covering maintenance on your commercial mower but WMI cannot deny warranty solely for the lack of receipts.

• As the commercial mower owner, you should however be aware that WMI may deny you warranty coverage if your commercial mower or a part has failed due to abuse, neglect, or improper maintenance or unapproved modifications.

• You are responsible for presenting your commercial mower to WMI’s distribution center or service center as soon as the problem exists. The warranty repairs should be completed in a reasonable amount of time, not to exceed 30 days. If you have a question regarding your warranty coverage, you should contact WMI’s warranty claims department at (301) 360-9810.

GENERAL EMISSIONS WARRANTY COVERAGE:

WMI warrants to the ultimate purchaser and each subsequent purchaser that the commercial mower is:

Designed, built and equipped so as to conform with all applicable regulations; and

Free from defects in materials and workmanship that cause the failure of a warranted part to be identical in all material respects to that part as described in WMI’s application for certification.

The warranty period begins on the date the commercial mower is delivered to an ultimate purchaser or first placed into service. The warranty period is two years.

Subject to certain conditions and exclusions as stated below, the warranty on emission-related parts is as follows:

(1) Any warranted part that is not scheduled for replacement as required maintenance in the written instructions supplied, is warranted for the warranty period stated above. If the part fails during the period of warranty coverage, the part will be repaired or replaced by WMI according to subsection (4) below. Any such part repaired or replaced under warranty will be warranted for the remainder of the period.

38

(2) Any warranted part that is scheduled only for regular inspection in the written instructions supplied is warranted for the warranty period stated above. Any such part repaired or replaced under warranty will be warranted for the remaining warranty period.

(3) Any warranted part that is scheduled for replacement as required maintenance in the written instructions supplied is warranted for the period of time before the first scheduled replacement date for that part. If the part fails before the first scheduled replacement, the part will be repaired or replaced by WMI according to subsection (4) below. Any such part repaired or replaced under warranty will be warranted for the remainder of the period prior to the first scheduled replacement point for the part.

(4) Repair or replacement of any warranted part under the warranty provisions herein must be performed at a warranty station at no charge to the owner.

(5) Notwithstanding the provisions herein, warranty services or repairs will be provided at all of our distribution centers that are franchised to service the subject engines or equipment.

(6) The commercial mower owner will not be charged for diagnostic labor that is directly associated with diagnosis of a defective, emission-related warranted part, provided that such diagnostic work is performed at a warranty station.

(7) WMI is liable for damages to other engine or equipment components proximately caused by a failure under warranty of any warranted part.

(8) Throughout the commercial mower warranty period stated above, WMI will maintain a supply of warranted parts sufficient to meet the expected demand for such parts.

(9) Any replacement part may be used in the performance of any warranty maintenance or repairs and must be provided without charge to the owner. Such use will not reduce the warranty obligations of WMI.

(10) Add-on or modified parts that are not exempted by the Air Resources Board may not be used. The use of any non-exempted add-on or modified parts by the ultimate purchaser will be grounds for disallowing a warranty claims.
