ALERT! YOUR SAFETY IS INVOLVED!

Figure 2

Safety Alert Symbol

The safety alert symbol appears above information which alerts you to unsafe actions or situations and will be followed by the word DANGER,

WARNING, or CAUTION.

DANGER: Indicates an imminently hazardous situation which, if not avoided, Will result in death or serious injury.

WARNING: Indicates a potentially hazardous situation which, if not avoided, Could result in death or serious injury.

CAUTION: Indicates a potentially hazardous situation which, if not avoided, May result in minor or moderate injury.

This manual uses two other words to highlight information. Important calls attention to special mechanical information and Note emphasizes general information worthy of special attention.

Safe Operating Practices

Training

• Read the Operator’s Manual and other training material. If the operator(s) or mechanic(s) can not read this manual, it is the owner’s responsibility to explain this material to them; other languages may be available on our website.

• 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, 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.

5

Safety

• 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.

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.

• 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. Do

Not use a nozzle lock open device.

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 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.

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.

• Lightning can cause severe injury or death. If lightning is seen or thunder is heard in the area,

Do Not operate the machine; seek shelter.

• 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.

• Park machine on level ground. 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

1.

Safe Zone-Use the mower here on slopes less than 15 degrees

2.

Danger Zone-Use a walk behind mower and/or hand trimmer on slopes greater than 15 degrees, near drop-offs and water.

3.

Water

• 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.

Using the Rollover Protection System

(ROPS)

A Rollover Protection System (roll bar) is installed on the unit.

WARNING

There is no rollover protection when the roll bar is down. Wheels dropping over edges, ditches, steep banks, or water can cause rollovers, which may result in serious injury, death or drowning.

• Do Not remove the ROPS.

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

• Lower the roll bar only when absolutely necessary.

• Do Not wear seat belt when the roll bar is down.

• Drive slowly and carefully.

• Raise the roll bar as soon as clearance permits.

Transporting the Machine

Use a heavy-duty trailer or truck to transport the machine. Ensure that the trailer or truck has all necessary lighting and marking as required by law.

Thoroughly read all of the safety instructions.

Knowing this information could help you, your family, pets, or bystanders avoid injury.

To transport the machine:

• Lock the brake and block the wheels.

• Securely fasten the machine to the trailer or truck with straps, chains, cable, or ropes.

• Secure a trailer to the towing vehicle with safety chains.

WARNING

Driving on the street or roadway without turn signals, lights, reflective markings, or a slow moving vehicle emblem is dangerous and can lead to accidents causing personal injury.

Do not drive machine on a public street or roadway.

26

Operation

Loading the Machine

Use extreme caution when loading or unloading machines onto a trailer or a truck. Use a full-width ramp that is wider than the machine for this procedure. Back up ramps and drive forward down

ramps (Figure 19).

1.

Back up ramps g028043

Figure 19

2.

Drive forward down ramps

Important: Do not use narrow individual ramps for each side of the machine.

Ensure the ramp is long enough so that the angle with

the ground does not exceed 15 degrees (Figure 20).

On flat ground, this requires a ramp to be at least four times (4X) as long as the height of the trailer or truck bed to the ground. A steeper angle may cause mower components to get caught as the unit moves from the ramp to the trailer or truck. Steeper angles may also cause the machine to tip or lose control. If loading on or near a slope, position the trailer or truck so that it is on the down side of the slope and the ramp extends up the slope. This will minimize the ramp angle.

WARNING

Loading a machine onto a trailer or truck increases the possibility of tip-over and could cause serious injury or death.

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

• Ensure that the ROPS is in the up position and use the seat belt when loading or unloading the machine. Ensure that the

ROPS will clear the top of an enclosed trailer.

• Use only a full-width ramp; do not use individual ramps for each side of the machine.

• Do not exceed a 15-degree angle between the ramp and the ground or between the ramp and the trailer or truck.

• Ensure the length of ramp is at least four times (4X) as long as the height of the trailer or truck bed to the ground. This will ensure that ramp angle does not exceed 15 degrees on flat ground.

• Back up ramps and drive forward down ramps.

• Avoid sudden acceleration or deceleration while driving the machine on a ramp as this could cause a loss of control or a tip-over situation.
