Used oil is a hazardous waste product and must be disposed of properly. Do not discard
with household waste. Check with your local authorities, service center, or dealer for
safe disposal/recycling facilities.
Remove Oil
1. With engine off but still warm, disconnect the spark plug wire(s) (D, Figure 11) and
keep it away from the spark plug(s) (E).
2. Remove the dipstick (A, Figure 12).
3. Remove the oil drain plug (F, Figure 13). Drain the oil into an approved container.
Note: Any of the oil drain plugs (G, Figure 13) may be installed in the engine.
4. After the oil has drained, install and tighten the oil drain plug (F, Figure 13).
5. When you drain the oil from the top oil fill tube (C, Figure 14), keep the spark plug
(E) end of the engine up. Drain the oil into an approved container.
WARNING
When 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.
Change Oil Filter, if equipped
Some models are equipped with an oil filter. For replacement intervals, see the
Maintenance Schedule.
1. Drain the oil from the engine. See Remove Oil section.
2. Remove the oil filter (H, Figure 12) and dispose of properly.
3. Before you install the new oil filter, lightly lubricate the oil filter gasket with fresh,
clean oil.
4. Install the oil filter by hand until the gasket contacts the oil filter adapter, then
tighten the oil filter 1/2 to 3/4 turns.
5. Add oil. See Add Oil section.
6. Start and run the engine. As the engine warms up, check for oil leaks.
7. Stop the engine and check the oil level. Correct oil level is at the top of the full
indicator (B, Figure 12) on the dipstick.

1. Remove the dipstick (A, Figure 12) and wipe with a clean cloth.
2. Slowly pour oil into the engine oil fill (C, Figure 12). Do not overfill. After adding
oil, wait one minute and then check the oil level.
3. Install and tighten the dipstick (A, Figure 12).
4. Remove the dipstick and check the oil level. Correct oil level is at the top of the full
indicator (B, Figure 12) on the dipstick.

WARNING
Fuel and its vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
• Never start and run 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
can damage the filter and solvents will dissolve the filter.
See the Maintenance Schedule for service requirements.
Various models use either a foam or a paper filter. Some models may also have an
optional pre-cleaner that can be washed and reused. Compare the illustrations in this
manual with the type installed on your engine and service as follows.
Foam Air Filter
1. Move the slide lock (A, Figure 15) to the unlock position and open the cover (B).
2. To prevent debris from falling into the carburetor, carefully remove the foam
element (C, Figure 15) from the air filter base.
3. Wash the foam element (C, Figure 15) in liquid detergent and water. Squeeze dry
the foam element in a clean cloth.
4. Saturate the foam element (C, Figure 15) with clean engine oil. To remove the
excess engine oil, squeeze the foam element in a clean cloth.
5. Install the foam element (C, Figure 15) onto the air filter base.
6. Close the cover (B, Figure 15) and move the slide lock (A) to the locked position.
Paper Air Filter
1. Loosen the fastener(s) (A, Figure 16).
2. Remove the cover (B, Figure 16).
3. To prevent debris from falling into the carburetor, carefully remove the pre-cleaner
(D, Figure 16) and the filter (C) from the air filter base.
4. Remove the pre-cleaner (D, Figure 16) from the filter (C).
5. To loosen debris, gently tap the filter (C, Figure 16) on a hard surface. If the filter is
excessively dirty, replace with a new filter.
6. Wash the pre-cleaner (D, Figure 16) in liquid detergent and water. Allow the pre-
cleaner to throughly air dry. Do not oil the pre-cleaner.
7. Assemble the dry pre-cleaner (D, Figure 16) to the filter (C).
8. Install the filter (C, Figure 16) and the pre-cleaner (D) onto the air filter base. Make
sure the filter fits securely on the air filter base.
9. Install the cover (B, Figure 16) and secure with the fastener(s) (A). Make sure the
fastener(s) is tight.
Service Fuel System

WARNING
Fuel and its vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
• Keep fuel away from sparks, open flames, pilot lights, heat, and other ignition
sources.
• Check fuel lines, tank, cap, and fittings frequently for cracks or leaks. Replace if
necessary.
• Before cleaning or replacing the fuel filter, drain the fuel tank or close the fuel shut-
off valve.
• If fuel spills, wait until it evaporates before starting engine.
• Replacement parts must be the same and installed in the same position as the
original parts.
Fuel Filter, if equipped
1. Before cleaning or replacing the fuel filter (A, Figure 17), drain the fuel tank or
close the fuel shut-off valve. Otherwise, fuel can leak out and cause a fire or
explosion.
2. Use pliers to squeeze tabs (B, Figure 17) on the clamps (C), then slide the clamps
away from the fuel filter (A). Twist and pull the fuel lines (D) off of the fuel filter.
3. Check the fuel lines (D, Figure 17) for cracks or leaks. Replace if necessary.
4. Replace the fuel filter (A, Figure 17) with an original equipment replacement filter.
5. Secure the fuel lines (D, Figure 17) with clamps (C) as shown.
Service Cooling System
WARNING
Running engines produce heat. Engine parts, especially muffler, become
extremely hot.
Severe thermal burns can occur on contact.
Combustible debris, such as leaves, grass, brush, etc., can catch fire.
• Allow muffler, engine cylinder and fins to cool before touching.
• Remove accumulated debris from muffler area and cylinder area.
NOTICE
Do not use water to clean the engine. Water could contaminate the fuel
system. Use a brush or dry cloth to clean the engine.
