Change Engine Oil
See Figure: 7, 8, 9, 10
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 (D, Figure 7) and
keep it away from the spark plug (E).
2. Remove the dipstick (A, Figure 8).
Oil Drain Plug, if equipped
1. Remove the oil drain plug (F, Figure 8). Drain the oil into an approved container.
Note: Various oil drain plugs (G, Figure 8) are installed.
2. After the oil has drained, install and tighten the oil drain plug (F, Figure 8).
Quick Oil Drain, if equipped
1. Disconnect the quick oil drain hose (H, Figure 9) from the side of the engine.
2. Turn and remove the oil drain cap (I, Figure 9). Carefully lower the quick oil drain
(H) into an approved container (J).
3. After the oil has drained, install the quick oil drain cap (I, Figure 9). Attach the
quick oil drain hose (H) to the side of the engine.
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 (K, Figure 10) 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 8) on the dipstick.
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 8) and wipe with a clean cloth.
2. Slowly pour oil into the engine oil fill (C, Figure 8). Do not overfill. After adding oil,
wait one minute and then check the oil level.
Note: Do not add oil at the quick oil drain (H, Figure 9), if equipped.
3. Install and tighten the dipstick (A, Figure 8).
4. Remove the dipstick and check the oil level. The correct oil level is at the top of the
full indicator (B, Figure 8) on the dipstick.
5. Install and tighten the dipstick (A, Figure 8) again.
6. Connect the spark plug wire (D, Figure 7) to the spark plug (E).
Service Air Filter
See Figure: 11, 12, 13
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.
Paper Air Filter (with pre-cleaner)
1. Loosen the fastener(s) (A, Figure 11).
2. Remove the air filter cover (B, Figure 11).
3. Remove the filter (C, Figure 11) and the pre-cleaner (D), if equipped.
4. To loosen debris, gently tap the filter on a hard surface. If the filter is excessively
dirty, replace with a new filter.
5. Wash the pre-cleaner (D, Figure 11), if equipped, in liquid detergent and water.
Allow the pre-cleaner to thoroughly air dry. Do not oil the pre-cleaner.
6. Assemble the dry pre-cleaner (D, Figure 11), if equipped, and the filter (C) into the
air filter base (E).
7. Install the air filter cover (B, Figure 11) and secure with fastener(s) (A). Make sure
the fastener(s) is tight.
Service Air Filter Assembly (Cartridge with pre-cleaner)
1. Loosen the fastener(s) (A, Figure 12, 13).
2. Remove the air filter cover (B, Figure 12, 13).
3. To remove the filter (C, Figure 12, 13), lift the end of the filter.
4. To loosen debris, gently tap the filter on a hard surface. If the filter is excessively
dirty, replace with a new filter.
5. Remove the pre-cleaner (D, Figure 12, 13) from the filter (C).
6. Wash the pre-cleaner (D, Figure 12, 13) in liquid detergent and water. Allow the
pre-cleaner to thoroughly air dry. Do not oil the pre-cleaner.
7. Assemble the dry pre-cleaner (D, Figure 12, 13), if equipped, to the filter (C).
8. Install the filter (C, Figure 12, 13) and pre-cleaner (D), if equipped, into the filter
base (E) and push down until the filter snaps in place.
9. Install the air filter cover (B, Figure 12, 13) and secure with fastener(s) (A). Make
sure the fastener(s) is tight.
Service Fuel System
See Figure: 14
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 replacing the fuel filter (A, Figure 14), if equipped, 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 14) 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 14) for cracks or leaks. Replace if necessary.
4. Replace the fuel filter (A, Figure 14) with an original equipment replacement filter.
5. Secure the fuel lines (D, Figure 14) 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.
