2. Stop the engine and position equipment on a level surface.
3. Let engine cool at least 2 minutes before removing the fuel cap.
4. Clean the fuel cap area of dirt and debris. Do not allow dirt or water to
enter the fuel tank.
5. Remove the fuel cap slowly to allow the pressure to equalize.
6. Check the fuel level.
7. Add fuel until it reaches the bottom of the fuel level limit marked in the fuel
tank. Take care to not overfill the tank. It may be necessary to lower the
fuel level depending on operating conditions (Fig. 16-1).
8. Reinsert the fuel tank cap and tighten.
9. Wipe up any spilled fuel
before starting the engine
or allow to evaporate.
Spilled fuel is both a fire
hazard and an
environmental hazard.
Dispose of the fuel soaked
rags in a proper hazardous
waste container.
HIGH ALTITUDE OPERATION
At high altitude, the standard air-fuel mixture will be too rich. Performance will
decrease and fuel consumption will increase. A very rich mixture will also foul
the spark plug and cause hard starting. High altitude performance can be
improved by specific modifications to the carburetor. If you always operate your
engine at altitudes above 1,000 meters, have a qualified service technician
perform the necessary modifications.
MAINTENANCE SCHEDULE
Remember that this schedule is based on the assumption that your machine will
be used for its designed purpose. Sustained high-load or high-temperature
operation, or use in unusually wet or dusty conditions, will require more
frequent service.
