Engine Maintenance

WARNING

The engine can become very hot. Touching a hot engine can cause severe burns.

Allow the engine to cool completely before service or making repairs around the engine area.

Servicing the Air Cleaner

Check the air cleaner daily or before starting the engine. Check for a buildup of dirt and debris around the air cleaner system. Keep this area clean. Also check for loose or damaged components. Replace all bent or damaged air cleaner components.

Note: Operating the engine with loose or damaged air cleaner components could allow unfiltered air into the engine causing premature wear and failure.

Note: Service the air cleaner more often under extremely dusty, dirty conditions.

Removing the Elements:

1.

Park the machine on a level surface, disengage the blade control switch, move the motion control levers to the brake position, stop the engine, remove the key, and wait until all moving parts stop before leaving the operating position.

2.

Clean around the air cleaner cover to prevent dirt from getting into the engine and causing damage.

3.

Loosen clamps and, remove the cover. Once taken off, loosen and remove the outer air filter element. Followed by the inner air filter. Remove the elements as shown in

Important: Do not clean the paper element with pressurized air or liquids, such as solvent, gas, or kerosene. Replace the paper element if it is damaged or cannot be cleaned thoroughly.

Servicing the Engine Oil

Checking the Engine Oil

Important: Do not overfill the crankcase with oil and run the engine; engine damage may result.

1.

Stop engine, wait for all moving parts to stop, and remove key. Engage parking brake.

Disconnect the spark plug wire and keep it away from the spark plug.

2.

Make sure the engine is cool so the oil has has time to drain into the sump.

3.

Keep dirt, grass clippings, etc., out of the engine, and clean the area around the dipstick before removing it.

1.

Dipstick

5.

If the level is lower then the “ADD” mark, wipe off the area around the oil fill cap, remove oil fill cap and add Exmark 4-Cycle Premium Engine

Oil to the “FULL” mark on the dipstick. Always check the level with the dipstick before adding more oil.

Do Not overfill.

Crankcase Capacity (when the filter is changed):

• Refer to Briggs and Stratton ® Owner’s

Manual for capacity.

Note: To prevent extensive engine wear or damage, always maintain the proper oil level in the crankcase. Never operate the engine with the oil level below the “ADD” mark or over the

“FULL” mark on the dipstick.

Changing the Engine Oil

1.

Stop engine, wait for all moving parts to stop, and remove key. Engage parking brake.

Disconnect the spark plug wire and keep it away from the spark plug.

2.

Drain oil while engine is warm from operation.

3.

Remove dip stick from the oil tank.

Fuel System Maintenance

Fuel 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.

• 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.

Replacing the Fuel Filter

Never install a dirty filter if it is removed from the fuel line.

1.

Park the machine on a level surface and disengage the blade control switch.

2.

Move the motion control levers outward to engage parking brake, stop the engine, remove the key, and wait for all moving parts to stop before leaving the operating position.

5

3.

The fuel filter is in the fuel line between the tank and engine.

4.

Squeeze the ends of the hose clamps together and slide them away from the filter.

g035841

Figure 7

Note: It is important to reinstall the fuel line hoses and secure with plastic ties the same as they were originally installed at the factory to keep the fuel line away from components that could cause fuel line damage.

5.

Remove the filter from the fuel lines.

6.

Install a new filter with the flow direction arrow coming from the fuel tank and pointing to the engine. Move the hose clamps close to the filter to secure it in place.
