Change Engine Oil

WARNING
Fuel and its vapors are flammable and explosive. Fire or explosion could result in
burns or death.
During operation, the engine and muffler become hot. If you touch a hot engine,
thermal burns can occur.
• If you drain the oil from the top oil fill tube, the fuel tank must be empty. If it is not
empty, fuel leakage can occur and cause a fire or an explosion.
• Before you touch the engine or muffler, stop the engine and wait two (2)
minutes. Make sure that the engine and muffler are safe to touch.
Used oil is a hazardous waste product and must be discarded of correctly. Do not
discard with household waste. Contact your local authorities, service center, or dealer
for safe disposal or recycling facilities.
Remove Oil
1. With the engine OFF but warm, disconnect the spark plug wire(s) (D, Figure 11),
and keep it away from the spark plugs (E).
2. Remove the dipstick (A, Figure 12).
Oil Drain Plug, if installed
1. Remove the oil drain plug (F, Figure 13). Drain the oil into an approved container.
NOTE: On Oil Xtend, remove the cap and filter (F, Figure 15) to drain the oil from the oil
housing.
NOTE: If the oil drain hole on your engine has a female drain plug (F, Figure 13), you
can replace it with a male drain plug (F).
2. After you drain the oil, install and tighten the oil drain plug (F, Figure 13).
Quick Oil Drain, if installed
1. Disconnect the oil drain hose (H, Figure 14) from the side of the engine.
2. Turn and remove the oil drain cap (I, Figure 14). Carefully lower the quick oil drain
hose (H) into an approved container (J).
NOTE: On Oil Xtend, remove the cap and filter (F, Figure 15) to drain the oil from the oil
housing.
3. After you drain the oil, install the oil drain cap (I, Figure 14). Attach the oil drain
hose (H) to the side of the engine.
Add Oil

Servicing the Air Filter
WARNING
Fuel vapors are flammable and explosive. Fire or explosion could result in burns
or death.
• Do not start and operate the engine with the air cleaner assembly (if equipped)
or the air filter (if equipped) removed.
NOTICE
Do not use pressurized air or solvents to clean the filter. Pressurized air could result in
damage to the filter and solvents will dissolve the filter.
See the Maintenance Schedule for service requirements.
Different models will use a foam or a paper filter. Some models could also have an
optional pre-cleaner that can be washed and used again. Compare the illustrations in
this manual with the type installed on your engine and service as follows.
Cyclonic Air Filter with Pre-Cleaner
WARNING
Gaseous vapors are flammable and explosive. Fire or explosion could result in
burns or death.
• Do not start and operate the engine with the air cleaner assembly (if equipped)
or the air filter (if equipped) removed.
NOTICE
Do not use pressurized air or solvents to clean the filter. Pressurized air could result in
damage to the filter and solvents will dissolve the filter.

2. Open the latch (C, Figure 21) and remove the filter (D).
3. Remove the pre-cleaner (E, Figure 21), if installed, from the filter (D).
4. To loosen debris, lightly tap the air filter on a hard surface. If the filter is dirty,
replace it with a new filter.
5. Clean the pre-cleaner in liquid detergent and water. Let it fully air dry. DO NOT
lubricate the pre-cleaner.
6. Assemble the dry pre-cleaner (E, Figure 21) to the filter (D).
