Service Miscellaneous
Using Proper Fuel and Stabilizer
Use regular grade unleaded fuel with an octane rating of 87 octane or
higher. Fuel blends containing up to 10% ethanol or up to 15% MTBE
reformulated fuel are acceptable. Do not use fuel or additives containing
methanol as engine damage can occur.
Always use fresh, clean fuel that is purchased in a quantity that can be
used within approximately 30 days. Fuel stabilizer should always be added
to the fuel each time fuel is purchased. Add stabilizer before filling the fuel
container to insure proper mixing. Such practice helps prevent engine
performance problems and allows fuel storage in the machine all year
without draining.
Store fuel in plastic containers to reduce condensation. Make sure the cap
on the fuel container is tight to reduce fuel contamination and evaporation.
For best fuel storage life, use a self-sealing gas can.
Fuel is blended to give best seasonal performance. To avoid engine
performance problems such as hard starting or vapor lock, use in-season
fuel. Use fuel during warm weather that was purchased during that
season, and use fuel during cold weather that was purchased during that
season.
Fuel can become stale in machines with engines that are used seasonally
or infrequently during a season. Stale fuel can produce varnish and plug
carburetor components which can affect engine performance.
Keep fuel storage container tightly covered and in a cool area out of direct
sunlight. Fuel can break down and degrade if not sealed properly or
exposed to sun and heat.
Condensation may collect in the fuel tank because of a variety of operating
or environmental conditions and, over time, may affect your machine’s
operation. Fill machine fuel tank at the end of daily.
Filling Fuel Tank
Fill fuel tank at the end of each day’s operation to prevent condensation
and freezing during cold weather.
1. Park machine safely. (See Parking Safely in the SAFETY section.)
2. Allow engine to cool.
3. Remove any trash from area around fuel tank cap.
4. Remove fuel tank cap slowly to allow any pressure built up in tank to
escape.
5. Fill fuel tank only to bottom of filler neck. Do not overfill.
6. Do not continue to “top off” the tank once full.
7. Install fuel tank cap, and turn cap until it clicks.
Checking Tire Pressure
1. Check tires for damage.
2. Check tire pressure with an accurate gauge.
3. Service tires safely. (See Tire Safety in the SAFETY section.)
4. Check that tires have equal air pressure. Add or remove air, if
necessary.
5. Refer to side of tire for correct tire inflation pressure.

CAUTION: Avoid injury! Fuel vapors are explosive and
flammable:
• Shut engine off before filling fuel tank.
• Allow engine to cool before refueling.
• Do not smoke while handling fuel.
• Keep fuel away from flames or sparks.
• Fill fuel tank outdoors or in well ventilated area.
• Clean up spilled fuel immediately.
• Use clean approved non-metal container to prevent static
electric discharge.
IMPORTANT: Avoid damage! Dirt and water in fuel can cause
engine damage:
• Clean dirt and debris from the fuel tank opening.
• Use clean, fresh, stabilized fuel.
• Fill the fuel tank at the end of each day’s operation to keep
condensation out of the fuel tank.
• Use a non-metallic funnel with a plastic mesh strainer when
filling the fuel tank or container.

CAUTION: Avoid injury! Touching hot surfaces can burn
skin. The engine, components, and fluids will be hot if the engine
has been running. Allow the engine to cool before servicing or
working near the engine and components.
