Safe Operating Practices

Training

• Read the Operator’s Manual and other training material. If the operator(s) or mechanic(s) can not read English it is the owner’s responsibility to explain this material to them.

• Become familiar with the safe operation of the equipment, operator controls, and safety signs.

• All operators and mechanics should be trained.

The owner is responsible for training the users.

• Never let children or untrained people operate or service the equipment. Local regulations may restrict the age of the operator.

• Only adults and mature teenagers should operate a mower, and even mature teenagers should have adult supervision. Be sure a teenager:

1. has read and understands the Operator’s

Manual and recognizes the risks involved;

2. is sufficiently mature to use caution; and

3. is of sufficient size and weight to operate the controls comfortably and to manage the mower without taking risks.

• The owner/user can prevent and is responsible for accidents or injuries occurring to himself or herself, other people or property.

Preparation

• Evaluate the terrain to determine what accessories and attachments are needed to properly and safely perform the job. Only use accessories and attachments approved by Exmark.

• Wear appropriate clothing including safety glasses, substantial footwear, long trousers, and hearing protection. Do Not operate when barefoot or when wearing open sandals. Long hair, loose clothing or jewelry may get tangled in moving parts.

CAUTION

This machine produces sound levels in excess of 85 dBA at the operator’s ear and can cause hearing loss through extended periods of exposure.

Wear hearing protection when operating this machine.

• Inspect the area where the equipment is to be used and remove all rocks, toys, sticks, wires, bones, and other foreign objects which can be thrown by the machine and may cause personal injury to the operator or bystanders.

Safety

DANGER

In certain conditions gasoline is extremely flammable and vapors are explosive.

A fire or explosion from gasoline can burn you, others, and cause property damage.

• Fill the fuel tank outdoors on level ground, in an open area, when the engine is cold. Wipe up any gasoline that spills.

• Never refill the fuel tank or drain the machine indoors or inside an enclosed trailer.

• Do Not fill the fuel tank completely full.

Fill the fuel tank to the bottom of the filler neck. The empty space in the tank allows gasoline to expand. Overfilling may result in fuel leakage or damage to the engine or emission system (if equipped).

• Never smoke when handling gasoline, and stay away from an open flame or where gasoline fumes may be ignited by spark.

• Store gasoline in an approved container and keep it out of the reach of children.

• Add fuel before starting the engine.

Never remove the cap of the fuel tank or add fuel when engine is running or when the engine is hot.

• If fuel is spilled, Do Not attempt to start the engine. Move away from the area of the spill and avoid creating any source of ignition until fuel vapors have dissipated.

• Do Not operate without entire exhaust system in place and in proper working condition.

DANGER

In certain conditions during fueling, static electricity can be released causing a spark which can ignite gasoline vapors. A fire or explosion from gasoline can burn you and others and cause property damage.

• Always place gasoline containers on the ground away from your vehicle before filling.

• Do Not fill gasoline containers inside a vehicle or on a truck or trailer bed because interior carpets or plastic truck bed liners may insulate the container and slow the loss of any static charge.

• When practical, remove gas-powered equipment from the truck or trailer and refuel the equipment with its wheels on the ground.

• If this is not possible, then refuel such equipment on a truck or trailer from a portable container, rather than from a gasoline dispenser nozzle.

• If a gasoline dispenser nozzle must be used, keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete.

WARNING

Gasoline is harmful or fatal if swallowed.

Long-term exposure to vapors has caused cancer in laboratory animals. Failure to use caution may cause serious injury or illness.

• Avoid prolonged breathing of vapors.

• Keep face away from nozzle and gas tank/container opening.

• Keep away from eyes and skin.

• Never siphon by mouth.

• Check that the operator’s presence controls, safety switches, and shields are attached and functioning properly. Do Not operate unless they are functioning properly.

6

Safety

Operation

WARNING

Operating engine parts, especially the muffler, become extremely hot. Severe burns can occur on contact and debris, such as leaves, grass, brush, etc. can catch fire.

• Allow engine parts, especially the muffler, to cool before touching.

• Remove accumulated debris from muffler and engine area.

• Install and maintain in working order a spark arrester before using equipment on forest-covered, grass-covered, or brush-covered unimproved land.

WARNING

Engine exhaust contains carbon monoxide, which is an odorless deadly poison that can kill you.

Do Not run engine indoors or in a small confined area where dangerous carbon monoxide fumes can collect.

• Operate only in daylight or good artificial light, keeping away from holes and hidden hazards.

• Be sure all drives are in neutral and parking brake is engaged before starting engine. Use seat belts with the roll bar in the raised and locked position.

• Never operate the mower with damaged guards, shields, or covers. Always have safety shields, guards, switches and other devices in place and in proper working condition.

• Never mow with the discharge deflector raised, removed or altered unless there is a grass collection system or mulch kit in place and working properly.

• Do Not change the engine governor setting or overspeed the engine.

• Stop engine, wait for all moving parts to stop, remove key and engage parking brake:

– Before checking, cleaning or working on the mower.

– After striking a foreign object or abnormal vibration occurs (inspect the mower for damage and make repairs before restarting and operating the mower).

– Before clearing blockages.

– Whenever you leave the mower.

• Stop engine, wait for all moving parts to stop, and engage parking brake:

– Before refueling.

– Before dumping the grass catcher.

WARNING

Hands, feet, hair, clothing, or accessories can become entangled in rotating parts. Contact with the rotating parts can cause traumatic amputation or severe lacerations.

• Do Not operate the machine without guards, shields, and safety devices in place and working properly.

• Keep hands, feet, hair, jewelry, or clothing away from rotating parts.

• NEVER carry passengers.

DO NOT operate the mower when people, especially children, or pets are in the area.

• Be alert, slow down and use caution when making turns. Look behind and to the side before changing directions.

• Stop the blades, slow down, and use caution when crossing surfaces other than grass and when transporting the mower to and from the area to be mowed.

• Be aware of the mower discharge path and direct discharge away from others.

• Do Not operate the mower under the influence of alcohol or drugs.

• Use extreme care when loading or unloading the machine into a trailer or truck.

• Use care when approaching blind corners, shrubs, trees, or other objects that may obscure vision.

Slope Operation

Use Extreme caution when mowing and/or turning on slopes as loss of traction and/or tip-over could occur. The operator is responsible for safe operation on slopes.

7

Safety

DANGER

Operating on wet grass or steep slopes can cause sliding and loss of control. Wheels dropping over edges, ditches, steep banks, or water can cause rollovers, which may result in serious injury, death or drowning.

• Do Not mow slopes when grass is wet.

• Do Not mow near drop-offs or near water.

• Do Not mow slopes greater than 15 degrees.

• Reduce speed and use extreme caution on slopes.

• Avoid sudden turns or rapid speed changes.

• Keep the roll bar in the raised and locked position and use seat belt.

• See inside the back cover to determine the approximate slope angle of the area to be mowed.

• Use a walk behind mower and/or a hand trimmer near drop-offs, ditches, steep banks or water.

(Figure 3).

• Remove or mark obstacles such as rocks, tree limbs, etc. from the mowing area. Tall grass can hide obstacles.

• Watch for ditches, holes, rocks, dips and rises that change the operating angle, as rough terrain could overturn the machine.

• Avoid sudden starts when mowing uphill because the mower may tip backwards.

• Be aware that operating on wet grass, across steep slopes or downhill may cause the mower to lose traction. Loss of traction to the drive wheels may result in sliding and a loss of braking and steering.

• Always avoid sudden starting or stopping on a slope. If tires lose traction, disengage the blades and proceed slowly off the slope.

• Follow the manufacturer’s recommendations for wheel weights or counter weights to improve stability.

• Use extreme care with grass catchers or attachments. These can change the stability of the machine and cause loss of control.

Operation

Operation

Note: Determine the left and right sides of the machine from the normal operating position.

Controls

Motion Control Levers

The motion control levers located on each side of the console control the forward and reverse motion of the machine. The levers control the flow of hydraulic oil from the hydrostatic pump to the drive wheel motor for each side.

Moving the levers forward or backward turns the wheel on the same side forward or in reverse. Wheel speed is proportional to the amount the lever is moved.

Moving the levers outward from the center position into the T-slot locks them in the neutral position

(Figure 6).

Choke Control

Located on right fuel tank.

The choke is used to aid in starting a cold engine.

Moving the choke lever forward will put the choke in the “ON” position and moving the choke lever to the rear, to the detent, will put the choke in the “OFF” position. Do Not run a warm engine with choke in the “ON” position.

Throttle Control

Located on right fuel tank.

The throttle is used to control engine speed. Moving the throttle lever forward will increase engine speed and moving the throttle lever to the rear will decrease engine speed. Moving the throttle forward into the detent is full throttle.

Brake Lever

Located on left side of unit, just to the front of the console.

The brake lever engages a parking brake on the drive wheels.

Pull the lever up and rearward to engage the brake.

Operation

Push the lever forward and down to disengage the brake.

The unit must be tied down and brake engaged when transporting.

Ignition Switch

Located on right fuel tank.

The ignition switch is used to start and stop the engine. The switch has three positions “OFF”, “ON” and “START”. Insert key into switch and rotate clockwise to the “ON” position. Rotate clockwise to the next position to engage the starter (key must be held against spring pressure in this position).

Note: Brake must be engaged, motion control levers out (neutral lock position) and PTO switch “OFF” to start engine. (It is not necessary for the operator to be in the seat to start the engine.)

Hour Meter

Located on the right fuel tank.

The hour meter is connected to a pressure switch installed in the engine block and it records the number of hours that the engine has run. If the ignition switch is left on without engine running, hour meter will not run.

Note: This switch is not a low oil sensor and will not alert the operator if the engine oil is low.

Fuel Shut-Off Valve

Located directly below the right side of console, next to the cubby.

The fuel shut-off valve is used to shut off the fuel when the machine will not be used for a few days, during transport to and from the jobsite, and when parked inside a building.

The valve has three positions, each position made in 1/4 turn increments.

The fuel gauge monitors the amount of fuel in the left tank only. Use the fuel from the right fuel tank first.

When the right fuel tank is empty, switch to the left fuel tank. Fuel gauge will monitor the remaining fuel.

Drive Wheel Release Valves

Located on the top right front corner of hydrostatic pumps.

Drive wheel release valves are used to release the hydrostatic drive system to allow the machine to be pushed without the engine running. Unhook seat latch and tilt seat up to gain access to pumps.

With a 5/8 inch wrench, turn both valves one turn counter-clockwise to release drive system. Turn clockwise to reset system.

Do Not overtighten. Do

Not tow machine.

Tracking Adjustment Knob

Located under the seat on the LH pump control link.

Rotating this knob allows fine tuning adjustments so that the machine tracks straight with the drive levers in the full forward position.

Stop machine and wait for all moving parts to stop.

Engage park brake. Unhook seat latch and tilt seat forward to gain access to the tracking knob. Rotate the knob clockwise (as viewed from the rear of the machine) to cause the machine to track more to the right and counterclockwise to cause the machine to track more to the left. Adjust in quarter-turn increments until the machine tracks straight. Check that the machine does not creep when in neutral with the park brake disengaged.

Important: Do Not rotate the knob too far, as this may cause the machine to creep in neutral.

Refer to the Motion Control Linkage Adjustment section in Maintenance.

PTO Engagement Switch

Located on right fuel tank.

Switch must be pulled out to the “ROTATE” position to engage the blades. Switch is pushed in to the “STOP” position to stop the blades.

Fuel Gauge

Located on the left fuel tank.

Operation

Pre-Start

Fill fuel tank on level ground. For best results use only clean, fresh regular grade unleaded gasoline with an octane rating of 87 or higher.

Important: Never use methanol, gasoline containing methanol, gasohol containing more than 10% ethanol, premium gasoline, or white gas because the fuel system could be damaged.

Do Not add oil to gasoline.

Do Not overfill fuel tank. Fill the fuel tank to the bottom of the filler neck. The empty space in the tank allows gasoline to expand. Overfilling may result in fuel leakage or damage to the engine or emission system (if equipped).

Make sure you understand the controls, their locations, their functions, and their safety requirements.

Refer to the Maintenance section and perform all the necessary inspection and maintenance steps.

WARNING

Loading a unit on a trailer or truck increases the possibility of backward tip-over.

Backward tip-over could cause serious injury or death.

• Use extreme caution when operating a unit on a ramp.

• Use only a single, full width ramp; Do

Not use individual ramps for each side of the unit.

• If individual ramps must be used, use enough ramps to create an unbroken ramp surface wider than the unit.

• Do Not exceed a 15° angle between ramp and ground or between ramp and trailer or truck.

• Avoid sudden acceleration while driving unit up a ramp to avoid tipping backward.

• Avoid sudden deceleration while backing unit down a ramp to avoid tipping backward.

Transporting

Transporting a Unit

Use a heavy-duty trailer or truck to transport the machine. Lock brake and block wheels. Securely fasten the machine to the trailer or truck with straps, chains, cable, or ropes. Be sure that the trailer or truck has all necessary lighting and marking as required by law. Secure a trailer with a safety chain.

CAUTION

This unit does not have proper turn signals, lights, reflective markings, or a slow moving vehicle emblem. Driving on a street or roadway without such equipment is dangerous and can lead to accidents causing personal injury. Driving on a street or roadway without such equipment may also be a violation of State laws and the operator may be subject to traffic tickets and/or fines.

Do Not drive a unit on a public street or roadway.

Loading a Unit

Use extreme caution when loading units on trailers or trucks. One full width ramp that is wide enough to extend beyond the rear tires is recommended instead of individual ramps for each side of the unit. The lower rear section of the tractor frame extends back between the rear wheels and serves as a stop for tipping backward. Having a full width ramp provides a surface for the frame members to contact if the unit starts to tip backward. If it is not possible to use one full width ramp, use enough individual ramps to simulate a full width continuous ramp.

Ramp should be long enough so that the angles between the ramp and the ground and the ramp and the trailer or truck do not exceed 15°. A steeper angle may cause mower deck components to get caught as the unit moves from ramp to trailer or truck. Steeper angles may also cause the unit to tip backward. If loading on or near a slope, position the trailer or truck so it is on the down side of the slope and the ramp extends up the slope. This will minimize the ramp angle. The trailer or truck should be as level as possible.

25

Operation

Important: Do Not attempt to turn the unit while on the ramp, you may lose control and drive off the side.

Avoid sudden acceleration when driving up a ramp and sudden deceleration when backing down a ramp.

Both maneuvers can cause the unit to tip backward.
