Oil
•
Check oil level regularly.
•
Be sure correct oil level is maintained. Check every five hours or daily before
starting engine. See oil checking procedure in the Operation section.
Change Engine Oil
Gasoline and its vapors are extremely flammable and explosive. Fire or
explosion can cause severe burns or death.
Change engine oil after the first five hours of operation, and every fifty hours or
once a season thereafter.
Before tipping the unit to drain the oil, the fuel tank must be empty or fuel
can leak out and result in a fire or explosion. To empty the fuel tank, run
the engine until it stops from lack of fuel.
IMPORTANT: Be sure to check engine on a level surface with the engine stopped.
Drain the oil while the engine is still warm to assure rapid and complete draining.
1.
With engine off but still warm, disconnect the spark plug wire and keep it
away from the spark plug.
2.
Place a suitable container next to the engine to catch the used oil.
3.
Remove the drain plug and drain the oil into the container by tipping the
engine toward the oil fill/dipstick. See Figure 18.
Used oil is a hazardous waste product. Dispose of used oil properly. Do not
discard with household waste. Check with your local authorities or Sears
Service Center for safe disposal/recycling facilities.
4.
Reinstall the drain plug and tighten it securely.
5.
Refill with the recommended oil and check the oil level. Refer to the
Operation Section.
Running the engine with a low oil level can cause engine damage.
6.
Reinstall the oil fill dipstick securely.
