Motion Control Levers
Park Brake
The park brake is found on the left of the machine. Pull the lever backward to operate the brake and push forward to release it.
The machine’s speed and direction are continuously variable using the two steering controls. The steering controls can be moved forward or backward about a neutral position.
There is a neutral position, which is locked if the steering controls are moved out.
When both controls are in the neutral position (N), the machine stands still. By equally moving both controls forward or backward, the machine moves in a straight line forward or backward.
IMPORTANT INFORMATION The machine must stand still when engaging the park brake.
Always set the park brake before dismounting.
Release the park brake before moving the mower.

Park
Brake
Reverse
For example, to turn right while moving forward, move the right control towards the neutral position. The rotation of the right wheel is reduced and the machine turns to the right.
Zero turn can be achieved by moving one control backward (behind the neutral position) and carefully moving the other steering control forward from its neutral position. The rotation direction when zero turning is determined by which steering control is moved backward behind the neutral position. If the left steering control is pulled backward, the machine turns to the left. Use more care when using this maneuver.
If the steering controls are in uneven positions when standing still or do not fit in the slots for moving the controls out, they can be adjusted.
WARNING ! The machine can turn very rapidly if one steering control is moved much further forward than the other.
12
The ignition switch is placed on the control panel and is used to start and stop the engine. On models equipped with headlights, turn the key clockwise to ACCESSORY for headlight use.
Choke Control
The choke control is used for cold starts to provide the engine with a richer fuel mixture.
For cold starts, pull the control up.
CONTROLS
Throttle Control
Service Meter
The throttle control regulates the engine speed and the rate of rotation of the blades, assuming the blade switch is pulled out.
To increase or decrease the engine speed, the control is moved forward or back respectively.
Avoid idling the engine for long periods, as there is a risk of fouling the spark plugs. USE FULL
THROTTLE WHEN MOWING, for best mower performance and battery charging.
Blade Switch
The service meter displays the total number of hours the engine has run and indicates when the engine and mower need servicing.
After every 50 hours of operation, an oil can icon will appear and stay on for two hours, before an automatic reset occurs. To manually reset the meter, turn the key off and on five times at one second intervals. To service the engine and mower, see the Service Journal of this manual.
NOTE: The service meter operates (clocks hours) only when the engine is running. Be sure to turn the key off when the unit is not in use, to prevent meter hours from accumulating.
Cutting Height Lever
To engage the mower deck blades, pull the knob up; the blades are disengaged when the knob is pressed down.
Fuel Shut Off Valve
The fuel shut off valve is located at the left rear of the seat. The valve is off when the handle tab is turned perpendicular to the fuel line.
To set the desired deck cutting height, press the release button and move the lever forward to the cutting height pin. See Before Starting in the
Operation section to change the cutting height.
The cutting height range is from 1-1/2" (38 mm) to 4" (102 mm) in 1/2" (13 mm) increments. The heights are measured from the ground up to the blade tip with the engine not running.
WARNING!
Do not make adjustments unless the engine is stopped and the park brake is activated.
IMPORTANT INFORMATION Always raise the deck to the highest position for transport.
13
CONTROLS
Fuse
Hydro Release Levers
The 20 amp primary fuse is located on the left hand side of the machine. It is accessed by tilting the seat forward. The fuse is a flat pin type used in automobiles.
Tracking
Transaxle bypass linkages must be engaged when pushing or pulling the mower. The release levers are located on each side of the rear of the unit below the rear engine plate. See Moving
Machine By Hand in the Operation section.
WARNING ! Bypass linkages are located close to the muffler. To prevent burns, the engine should be shut off and allowed to cool before the bypass linkage levers are handled.
Fuel Tank
If the mower is not tracking straight, check the air pressure in both rear tires. Recommended air pressure for the rear tires is 15 psi (1 bar).
1. Tracking adjustments are made using the tracking bolts. The tracking bolts act as limiting devices for the motion control levers when in the full-forward position.
2. For preliminary tracking adjustment, move unit to an open, unobstructed area such as an empty parking lot or open field.
3. Back the tracking bolts out until flush with nut.
4. Test operate unit by driving it at full throttle and the full forward position on both motion control levers. Gradually turn in the tracking bolt on the right hand side until the unit noticeably starts drifting right.
5. Drive forward at full throttle with both motion control levers in the full forward position.
Gradually turn in the left tracking bolt until unit tracks straight.
Read the safety instructions before refueling. The capacity for the tank is three gallons.
Regularly check the gas cap gasket for damage and keep the cap properly tightened.
The engine will run on a minimum of 87-octane unleaded gasoline (no oil mix). Environmentally adapted alkylate gasoline can be used. See
Technical Data concerning ethanol fuel.
Methanol fuel is not allowed. Do not use E85 alcohol based fuel. Damage to the engine and components may occur.
When operating in temperatures below 32°F, use fresh, clean winter grade gasoline to help insure good cold weather starting.
WARNING ! Gasoline is highly flammable.
Observe caution and fill the tank outdoors (see the Safety section).
14
CONTROLS
WARNING ! Fill to bottom of filler neck.
Do not overfill. Wipe off spilled oil or fuel. Do not store, spill or use gasoline near an open flame.
WARNING!
The engine and the exhaust system, become very hot during operation.
There is a risk for burns if touched. Let engine and exhaust system to cool before refueling.
IMPORTANT INFORMATION Experience indicates that alcohol blended fuels (called gasohol, ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage. To avoid engine problems, the fuel system must be emptied before storage of 30 days or longer. Drain the gas tank, start the engine and let it run until the fuel lines and carburetor are empty. Use fresh fuel the next season. See Storage for more information. Do not use engine or carburetor cleaners in the fuel tank or permanent damage may occur.
15
OPERATION
Read the Safety section and following pages, if you are unfamiliar with the machine.
Training
Due to unique steering capabilities, zero turn mowers are far more maneuverable than typical riding mowers.
This section must be reviewed in its entirety prior to attempting to move the mower under its own power. When first operating the mower or until becoming comfortable with controls, use a reduced throttle speed and reduced ground speed. DO NOT move control levers to the furthest forward or reverse positions during initial operation.
First time users must become familiar with the mower’s movement on a hard surface, such as concrete or blacktop PRIOR to attempting to operate on turf. Until the operator becomes comfortable with the mower controls and zero turning capability, overly aggressive maneuvers may damage turf.
Steering
To move forward and backward
The direction and speed of the mower’s movements are effected by the movement of the control lever(s) on each side of mower. The left control lever controls the left wheel. The right control lever controls the right wheel.
For first time use, push the mower (see Moving
Machine By Hand in the Operation section) to an open, flat area without other people, vehicles or obstacles nearby. To move the unit under its own power, the operator must sit in the seat and start the engine (see Before Starting in the
Operation section). Adjust the engine speed to idle, disengage the park brake but do not engage the blades at this time. Rotate control levers inward. As long as the control levers have not been moved forward or backwards, the mower will not move.
Slowly move both control levers forward slightly.
This will let the mower start moving forward in a straight line. Pull the control levers back to the neutral position and the mower will stop moving.
Pull back slightly on control levers, allowing the mower to move backwards. Push the control levers forward to the neutral position and mower will stop moving.
To turn to the right
While moving in a forward direction, pull the right lever back towards the neutral position while maintaining the position of the left lever, this will slow the rotation of the right wheel and cause the machine to turn in that direction.
To turn to the left
While moving in a forward direction pull the left lever back towards the neutral position while maintaining the position of the right lever, this will slow the rotation of the left wheel and cause the machine to turn in that direction.
To zero turn
While moving in a forward direction, first pull both control levers back until the mower stops or slows dramatically.
Then by alternating one lever slightly to the forward position and the other in the reverse position, complete the turn.
WARNING ! Make sure the work area is free of stones and other objects that could be thrown by the rotating blades.
Before Starting
1. Read the sections on Safety and Controls before starting the machine.
2. Perform the daily maintenance before starting (see Maintenance Schedule in the
Maintenance section).
3. Check that there is sufficient fuel in the fuel tank.
4. Adjust the seat to the desired position.
5. Set the deck cutting height by inserting the lift pin into the desired cut height.
16
OPERATION
The following conditions must be fulfilled before the engine can be started:
• The blade switch must be pressed downward into the disengaged position.
• The park brake must be up into the engaged position.
• Both steering controls must be in the locked
(outer) neutral position.
Starting the Engine
1. Sit on the seat.
2. Raise the mower deck by pushing the release button on the top of the lifting lever. Pull the lifting lever backward to the locked (transport) position.
5. Move the steering controls outward to the locked (outer) neutral position.
6. Move the throttle to the middle position. If the engine is cold, the choke control should be pulled up.
3. Engage the park brake by pushing the release button in and pulling the lever fully upwards.
4. Disengage the mower blades by pressing the blade switch down.
7. Press in and turn the ignition key to the start position.

IMPORTANT INFORMATION Leaving the ignition switch in a position than OFF will cause the battery to be discharged.
Operating on Hills
Read the Safety Instructions Driving on Slopes in the Safety section.
• Use the slowest speed possible before starting up or down hills.
• Avoid stopping or changing speed on hills.
• If stopping is necessary, pull drive levers into the neutral position and push outward. Engage the park brake.
• To restart movement, release the park brake.
• Pull the control levers back to the center of the mower and press forward to regain forward motion.
• Make all turns slowly.
Mowing Tips
• Observe and flag rocks and other fixed objects to avoid collisions.
• Begin with a high cutting height and reduce it until the desired mowing result is attained.
Cut the average lawn to 2-1/2" during the cool season and over 3" during the hot months. For healthier and better looking lawns, mow often after moderate growth.
• For best cutting performance, mow grass over
6" in height twice. Make the first cut relatively high; the second to the desired height.
• The mowing result will be best with a high engine speed (the blades rotate rapidly) and low speed (the rider moves slowly). If the grass is not too long and dense, the driving speed can be increased without negatively affecting the mowing result.
• The finest lawns are obtained by mowing often. The lawn becomes more even and the grass clippings more evenly distributed over the mown area. The total time taken is not increased as a higher operating speed can be used without poor mowing results.
• When mowing large areas, start by turning to the right so that clippings will discharge away from shrubs, fences, driveways, etc. After one or two rounds, mow in the opposite direction making left hand turns until finished.
WARNING!
Do not drive the mower on terrain that slopes more than 10 degrees. Mow slopes up and down, never side to side. Do not drive across slopes. Avoid sudden directional changes.
• Avoid mowing wet lawns. The mowing result is poorer because the wheels sink into the soft lawn, clumps build, and grass clippings fasten under the cowling.
• Hose the mower deck underside with water after each use. When cleaning, raise the mower into the transport position. Make sure the mower is cooled and the engine is off.
• Use compressed air to clean top surface of the deck. Avoid flooding water on top surface, engine and electrical components.
• When the mulching kit is used, it is important that the mowing interval is frequent.
18
OPERATION
Moving Machine By Hand
When pushing or pulling the mower, engage the
EZT bypass linkages. The EZT bypass linkages are located on the rear of the frame, below the rear engine guard.
1. Raise the deck into the highest cutting position.
2. Engage the park brake.
3. Pull the EZT bypass linkages up and out of the keyhole slots. Release the levers with the head outside the frame and held in the bypass position.
4. To reengage the EZT’s to drive, reverse the above procedure.
Load the machine into truck or trailer by driving slowly up the ramps. DO NOT LIFT! The machine is not intended to be lifted by hand.
WARNING!
Use extreme caution when loading the machine into a truck or trailer using ramps. There is the possibility of serious injury or death if the machine falls off the ramps.
WARNING!

MAINTENANCE
Safety System
The machine is equipped with a safety system that prevents starting or driving under the following conditions.
The engine can only be started when:
• the mower deck is disengaged.
• the steering controls are in the outer, locked neutral position.
• the park brake is on.
Make daily inspections to ensure that the safety system works by attempting to start the engine when one of the conditions is not met. Change the conditions and try again.
If the machine starts when one of these conditions is not met, turn the machine off and repair the safety system before using the machine again.
Make sure the engine stops when the park brake is not engaged and the operator leaves the seated position.
Check that the engine stops if the mower blades are engaged and the driver temporarily moves off the driver’s seat.
IMPORTANT INFORMATION To be able to drive, the driver must sit in the seat and release the park brake before the steering controls can be moved into the neutral position, otherwise the engine will stop.
Park Brake
Visually check that no damage is found on the lever, links, or switch belonging to the park brake.
Perform a standstill test and check that there is sufficient braking. For park brake adjustments, contact the RedMax service workshop.
Cutting Blades
CAUTION!
Blades are sharp. Protect your hands with gloves and/or wrap blades with a heavy cloth when handling.
The sharpening of blades must be carried out by an authorized service workshop.
For the best mowing effect, it is important that the blades are well sharpened and not damaged.
Replace blades that have been bent or cracked when hitting obstacles.
Let the service workshop decide whether a blade with large nicks can be repaired/ground or must be replaced. Balance the blades after sharpening.
Check the blade mounts.
Blade Replacement
1. Remove blade bolt by turning it counter clockwise.
2. Install new or re-sharpened blade with stamped GRASS SIDE facing towards ground/grass (down) or THIS SIDE UP facing deck and cutter housing.
3. Install and tighten blade bolt securely.
4. Torque blade bolt to 45-55 ft/lbs (61-83 Nm).
IMPORTANT INFORMATION The special blade bolt is heat treated. Replace it with a
RedMax bolt if required. Do not a use lower grade hardware than specified.
Caster Wheels
Check every 200 hours. Check that wheels rotate freely.
Foam filled tires or solid tires will void the warranty.
To replace, remove nut and caster bolt. Pull the wheel out of the yoke and take care with the spacer. Reinstall in reverse order. Tighten the caster bolt and torque to 45 ft-lbs (61 Nm).
WARNING ! Faulty adjustment will result in reduced braking and can cause an accident.
Tire Pressures
All tires must be at 15 psi / 103 kPa / 1 bar.
IMPORTANT INFORMATION DO NOT add a tire liner or foam fill material to the tires.
Excessive loads created by foam filled tires will cause premature failures.
Only use O.E.M. specified tires.
23
MAINTENANCE
V-belts
Check at 100 hour intervals of operation. Check for severe cracking and large nicks.
NOTE: The belt will show some small cracks in usual operation.
The belts are not adjustable. Replace belts if they begin to slip from wear.
Deck Belt Removal
1. Park on a level surface. Engage park brake.
2. Lower the deck into the lowest cutting position.
3. Remove the bolts from the belt shields and remove the shields.
4. Remove dirt or grass from around the cutter housings and the deck surface.
5. Loosen the nut securing the belt guide. Pull the belt guide up out of the idler arm.
7. Set the loosened belt guide into the idler arm hole and tighten the pulley bolt.
8. Replace belt shields on both mandrel housings and secure with fasteners.
Adjusting the Mower Deck
Leveling deck
Adjust the deck while the mower is on a level surface. Make sure the tires are inflated to the correct pressure. See Technical Data /
Transmission . If tires are under or over inflated, the deck cannot be correctly adjusted. Raise the deck to the highest (transport) position.
The deck must be adjusted slightly higher in the rear.
NOTE: To insure the precision of the leveling procedure, the mower deck drive belt must be installed before leveling the deck.
1. Wear heavy gloves. Turn each outer blade tip to align front to rear with the deck side-to-side.
6. Push inward on the idler arm to release the tension on the belt.
7. Carefully lift the belt over the top of the cutter housing pulleys and remove belt from the deck.
Deck Belt Installation
NOTE: For ease in installing the deck belt, refer to the routing decal on the top of the deck.
1. Wind the deck belt around the electric clutch pulley located on the engine shaft.
2. Route the belt forward and up onto the deck.
3. Position the belt around spring loaded idler pulley.
4. Wind the belt around the stationary idler pulley and the mandrel housings.
5. Push inward on the idler arm and carefully put the belt over the stationary idler pulley. When the belt is correctly routed, slowly release the idler arm to tension the belt.
6. Double check the belt routing to make sure it matches the routing decal, and the belt does not have twists.
2. Measure from the floor surface up to the bottom of the blade tip on the discharge side of the mower deck. Record the measurement.
3. Move to the opposite side, check that measurement is the same. If adjustment is required—with a 3/4" or adjustable wrench, turn the lift link adjustment nuts on either side counter clockwise to lower or clockwise to raise. Adjust until both measurements are equal.
4. Turn either blade to align with the deck frontto-rear. If the front blade tip does not measure
1/4" to 3/8" (6,35 mm to 9,52 mm) lower
24
MAINTENANCE than the rear, remove the foot plate access the front deck adjustment. With an adjustable wrench, loosen the rear jam nut on the front suspension linkage.
Make adjustment to level with the front lift link nut. Clockwise raises the front of the mower, counter clockwise will lower the front. Adjust the nut until rear blade tip is 1/4" to 3/8" higher than the front blade tip.
Cleaning
Regular cleaning, especially under the mower deck, will increase the machine’s life-span. Clean the machine directly after use (after it is cooled), before the debris sticks.
Do not spray water on the top of the mower deck.
Use compressed air to clean the top side of the mower deck. Do not use a high pressure washer or steam cleaner. Avoid spraying engine and electrical components with water.
Regularly clean the underside of the deck with normal water pressure. Attach the quick connect
(from the accessory packet) to a garden hose.
After mowing, snap the hose to the cleanout port and turn on water supply.
NOTE: This will position the mower deck in a standard measurement position. Depending on the type of grass being mowed or environmental conditions, additional adjustments may be required to get the desired cut.
Restart the mower and engage the blades to use the spinning action to wash away debris. Make sure the hose is away from the mower blades.
Do not rinse hot surfaces with cold water. Let unit cool before washing.
CAUTION! Wear eye protection when cleaning or washing the mower.

STORAGE
Winter Storage
The machine must be readied for storage at the end of the mowing season, or if it will not be in use for more than 30 days.
Fuel allowed to stand for long periods of time (30 days or more) can leave sticky residues that can plug the carburetor and disrupt engine function.
Fuel stabilizers are an permitted option as regards to the sticky residues that can occur during storage.
Add stabilizer to the fuel in the tank or in the storage container. Always use the mixing ratios specified by the manufacturer of the stabilizer.
Run the engine for at least ten minutes after adding the stabilizer so that it reaches the carburetor. Do not empty the fuel tank and the carburetor if a stabilizer has been added.
WARNING ! Do not store an engine with fuel in the tank indoors or in poorly ventilated spaces where fuel vapor can come in contact with open flames, sparks, or a pilot light such as in a boiler, hot water tank, clothes dryer, etc. Handle the fuel with care. It is very flammable and can cause serious personal injury and property damage. Drain the fuel into an approved container outdoors and store far away from open flame or sources of ignition. Do not use gasoline for cleaning. Use a degreaser and warm water.
To ready the machine for storage:
1. Thoroughly clean the machine, especially under the mower deck. Touch up damage to the paint and spray a thin layer of oil on the underside of the mower deck to avoid corrosion.
2. Inspect the machine for worn or damaged parts and tighten nuts or screws that may have become loose.
3. Change the engine oil; dispose of properly.
4. Empty the fuel tanks or add a fuel stabilizer.
Start the engine and let it run until the carburetor is drained of fuel or the stabilizer has reached the carburetor.
5. Remove the spark plug and pour about a tablespoon of engine oil into the cylinder.
Turn over the engine so that the oil is evenly distributed and then refit the spark plug.
6. Lubricate all grease zerks, joints, and axles.
7. Remove the battery. Clean, charge, and store the battery in a cool place, but protect it from direct cold.
8. Store the machine in a clean, dry place and cover it for extra protection.
Service
When ordering spare parts, please specify the purchase year, model, type, and serial number.
