Change Engine Oil

See Figure: 14, 15, 16, 17
WARNING
Fuel and its vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
Running engines produce heat. Engine parts, especially muffler, become extremely
hot.
Severe thermal burns can occur on contact.
• 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.
• Allow muffler, engine cylinder and fins to cool before touching.
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
You can drain the oil from the bottom drain hole or from the top oil fill tube.
1. With engine off but still warm, disconnect the spark plug wire (D, Figure 14) and keep
it away from the spark plug (E).
2. Remove the oil drain plug (F, Figure 15). Drain the oil into an approved container.
Note: Any of the oil drain plugs (F, Figure 15) may be installed in the engine.
3. After the oil has drained, install and tighten the oil drain plug (F, Figure 15).
4. If you drain the oil from the top oil fill tube (C, Figure 16), keep the spark plug (E)
end of the engine up. Drain the oil into an approved container.
WARNING
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.
Add Oil
• Make sure the engine is level.
• Clean the oil fill area of any debris.
• See the Specifications section for oil capacity.
1. Remove the dipstick (A, Figure 17) and wipe with a clean cloth.
2. Slowly pour oil slowly into the engine oil fill (C, Figure 17). Do not overfill. After
adding oil, wait one minute and then check the oil level.
3. Install and tighten the dipstick (A, Figure 17).
4. Remove the dipstick and check the oil level. Correct oil level is at the top of the full
indicator (B, Figure 17) on the dipstick.
5. Reinstall and tighten the dipstick (A, Figure 17).
6. Connect the spark plug wire (D, Figure 14) to the spark plug (E).

Service Air Filter

See Figure: 18, 19
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.
1. Loosen the fastener(s) (A, Figure 18, 19).
2. Remove the cover (B, Figure 18, 19).
3. Remove the fastener(s) (E, Figure 19), if equipped.
4. To prevent debris from falling into the carburetor, carefully remove the pre-cleaner
(D, Figure 18, 19) and the filter (C) from the air filter base.
5. To loosen debris, gently tap the filter (C, Figure 18, 19) on a hard surface. If the filter
is excessively dirty, replace with a new filter.
6. Remove the pre-cleaner (D, Figure 18, 19) from the filter (C).
7. Wash the pre-cleaner (D, Figure 18, 19) in liquid detergent and water. Allow the pre-
cleaner to throughly air dry. Do not oil the pre-cleaner.
8. Assemble the dry pre-cleaner (D, Figure 18, 19) to the filter (C).
9. Install the filter (C, Figure 18, 19) and the pre-cleaner (D). Make sure the filter fits
securely on the air filter base.
10. Make sure the gasket (F, Figure 19), if equipped, is in correct position under the filter
(C). Secure filter (C) with fastener(s) (E), if equipped.
11. Install the cover (B, Figure 18, 19) and secure with the fastener(s) (A). Make sure
the fastener(s) is tight.
Service Fuel System
See Figure: 20, 21
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 20), 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 20) 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 20) for cracks or leaks. Replace if necessary.
4. Replace the fuel filter (A, Figure 20) with an original equipment replacement filter.
5. Secure the fuel lines (D, Figure 20) with clamps (C) as shown.
Fuel Strainer, if equipped
1. Remove the fuel cap (A, Figure 21).
2. Remove the fuel strainer (B, Figure 21).
3. If the fuel strainer is dirty, clean or replace it. If you replace the fuel strainer, make
sure to use an original equipment replacement fuel strainer.
