engine oil fill. Wait one minute and then check the oil level.
NOTE: Do not add oil at the quick oil drain, if equipped.
3. Install and tighten the dipstick (A, Figure 15).
4. Remove the dipstick and check the oil level. The correct oil level is at the top of the
full indicator (B, Figure 15) on the dipstick.
5. Install and tighten the dipstick (A, Figure 15).
6. Connect the spark plug wire(s) to the spark plug(s). See Remove Oil section.

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.
Paper Air Filter
1. Pull up on the cover handle (A, Figure 16). Turn the cover handle in the direction of
the engine and then remove the cover (B).
2. Remove the pre-cleaner (C, Figure 16), if installed, and the filter (D).
3. To loosen unwanted material, lightly tap the filter (D, Figure 16) on a hard surface. If
the filter is dirty, replace it with a new filter.
4. Clean the pre-cleaner (C, Figure )16, in liquid detergent and water. Let the pre-
cleaner (C) fully air dry. DO NOT lubricate the pre-cleaner.
5. Assemble the dry pre-cleaner (C, Figure 16) and the filter (D) to the engine base
(E).
6. Align the tabs (F, Figure 16) on the cover (B) with the slots (G) in the blower
housing.
7. Turn the cover handle (A, Figure 16) back and push down to lock it in position.
Paper Air Filter
1. Loosen the fastener(s) (A, Figure 17).
2. Remove the cover (B, Figure 17).
3. To remove the filter (C, Figure 17), lift the end of the filter, and then pull the filter off
the intake (D).
4. To loosen unwanted material, lightly tap the filter (D, Figure 17) on a hard surface. If
the filter is dirty, replace it with a new filter.
5. Remove the pre-cleaner (E, Figure 17), if installed, from the filter (C).
6. Clean the pre-cleaner (E, Figure 17), in liquid detergent and water. Let the pre-
cleaner fully air dry. DO NOT lubricate the pre-cleaner.
7. Assemble the dry pre-cleaner (E, Figure 17), if installed, to the filter (C).
8. Install the filter (C, Figure 17) on the intake (D). Push the end of the filter down into
the engine base. Make sure that the filter is tight at the engine base.
9. Install the air filter cover (B, Figure 17) and attach with fastener(s)

Servicing the Fuel System

WARNING
Fuel and its vapors are flammable and explosive. Fire or explosion could result in
burns or death.
• Keep fuel away from sparks, open flames, pilot lights, heat, and other ignition
sources.
• Frequently examine the fuel lines, fuel tank, fuel cap, and connections for cracks
or leaks. Replace damaged parts.
• Before you clean or replace the fuel filter, drain the fuel tank or close the fuel
shut-off valve.
• If fuel spills, wait until it dries before you start the engine.
• Replacement parts must be of the same design and installed in the same
position as the original parts. Other parts could result in damage or an injury.
Fuel Filter, if installed
1. Before you clean or replace the fuel filter (A, Figure 18), drain the fuel tank or close
the fuel shut-off valve. If the fuel tank is not drained, fuel leakage could occur and
cause a fire or explosion.
2. Use pliers to squeeze tabs (B, Figure 18) on the clamps (C), then move the clamps
away from the fuel filter (A). Twist and pull the fuel lines (D) off of the fuel filter.
3. Examine the fuel lines (D, Figure 18) for cracks or leaks. Replace if necessary.
4. Replace the fuel filter (A, Figure 18) with an original equipment replacement filter.
5. Attach the fuel lines (D, Figure 18) with clamps (C).
Fuel Strainer, if installed
1. Remove the fuel cap (A, Figure 19).
2. Remove the fuel strainer (B, Figure 19).
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.

Servicing the Cooling System

WARNING
During operation, the engine and muffler become hot. If you touch a hot engine,
thermal burns can occur.
Combustible debris, such as leaves, grass, and brush can catch fire.
• 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.
• Remove debris from the muffler and engine.
NOTICE
Do not use water to clean the engine. Water could cause contamination of the fuel
system. Use a brush or dry cloth to clean the engine.
This is an air cooled engine. Dirt or debris can prevent air flow and cause the engine to
become too hot and result in unsatisfactory performance and decreased engine life.
1. Use a brush or dry cloth to remove debris from the air intake grille.
2. Keep linkage, springs, and controls clean.
3. Keep the area around and behind the muffler, if equipped, free of combustible
debris.
4. Make sure the oil cooler fins, if equipped, are clean.
After a period of time, the cylinder cooling fins can collect debris and cause the engine
to overheat. This unwanted material cannot be removed without partial disassembly of
