Oil and Oil Filter
Change oil after the first 5 hours of operation.
After that, change oil after every 50 hours of
operation. Change oil more often if engine is
operated in dirty or dusty conditions, under
heavy loads, or in high ambient temperatures.
1. Remove oil drain plug from side or bottom
of engine and drain oil while the engine is
still warm.
2. Install drain plug.
3. Remove oil filter, if equipped.
• Clean surface of filter mounting adapter.
• Apply light coat of clean engine oil to new
filter gasket.
4. Screw new filter on by hand until gasket
contacts filter mounting adapter. Then
tighten an additional 1/2 to 3/4 turn.
5. Fill crankcase with the correct amount of
new oil.
6. Start engine and run at idle for a minute or
so.
7. Shut engine off and wait for oil to settle
back into the cylinder.
8. Check dipstick. If necessary, add more oil
slowly to bring level to FULL mark on
dipstick.
9. Replace oil fill cap and dipstick.
10. Start and run engine. Check for oil leaks.
Spark Plug
Spark plugs should be replaced every year.
NOTE: In some areas, local law requires using
resistor spark plugs to suppress radio frequency
interference.
1. Disconnect spark plug wire.
2. Remove and inspect spark plug for wear
and damage. Replace spark plug if
electrodes are burned away, or the
porcelain is cracked.
3. Do not blast clean spark plugs. Clean by
scraping or wire brushing, and then
washing in a commercial solvent.
4. Using a wire gage, check and set the gap
(A, Figure 15) per Section 12 -
Specifications.
Figure 17
5. Re-install spark plug and torque to values
listed in Section 12 - Specifications.
6. Connect spark plug wire.
WARNING
Gasoline and its vapors are extremely
flammable and explosive.
Fire or explosion can cause severe
burns or death.
If you drain the oil from the top oil fill tube, 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.
NOTICE
Do not overfill. Overfilling can cause seals
to fail, smoke from the exhaust, or
overheating due to oil foaming.
NOTICE
Spark plugs have different thread “reach”
and heat ranges. When changing a spark
plug, use only the specified replacement,
otherwise engine damage could occur.
