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 servicing requirements.
Different models will use a foam or a paper filter. Some models could also have an
optional pre-cleaner that can be cleaned and used again. Compare the illustrations in
this manual with the type installed on your engine and service as follows.
Cyclonic Air Filter with Safety Filter
1.
Open the fastener(s) (A, Figure 15) and remove the cover (B).
2.
Remove the air filter (C, Figure 15).
3.
To loosen debris, lightly tap the air filter on a hard surface. If the air filter is dirty,
replace it with a new air filter.
4.
To remove the safety filter (D, Figure 15), if installed, carefully pull it away from the
air cleaner body (E). Make sure that dirt or debris does not go into the engine.
5.
Install the new safety filter (D, Figure 15) in the air cleaner body (E).
6.
Install the air filter (C, Figure 15) above the safety filter (D).
7.
Install the cover (B, Figure 15) and close the fastener(s) (A).
Low Profile Air Filter
1.
Remove the fastener(s) (A, Figure 16).
2.
Remove the cover (B, Figure 16).
3.
Remove the fastener(s) (C, Figure 16) and retainer (D).
4.
Remove the air filter (E, Figure 16).
5.
Remove the pre-cleaner (F, Figure 16), if installed, from the air filter (E).
6.
To loosen unwanted material, lightly tap the air filter (E, Figure 16) on a hard
surface. If the air filter is dirty, replace with a new air filter.
7.
Clean the pre-cleaner (F, Figure 16), if installed, in liquid detergent and water. Make
sure the pre-cleaner is fully dry. Do not lubricate the pre-cleaner.
8.
Assemble the dry pre-cleaner (F, Figure 16), if installed, to the air filter (E).
9.
Install the air filter (E, Figure 16) with the retainer (D) and fastener(s) (C).
10. Install the cover (B, Figure 16) with the fastener(s) (A). Make sure that the
fastener(s) is tight.
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.
This is an air cooled engine. Dirt or debris can stop the 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 area (A, Figure 17).
2.
Keep linkage, springs, and controls (B, Figures 17, 18) clean.
3.
Keep the area around and behind the muffler (C, Figures 17, 18) free of
combustible debris.
4.
Make sure that the oil cooler fins (D, Figure 17) are free of dirt and unwanted
material.
5.
Loosen the fastener(s) (E, Figures 17, 18) and remove the debris access panels
(F). Remove grass and debris that has collected on the cylinders.
6.
Install the debris access panels (F, Figures 17, 18) and attach with fastener(s) (E).
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.
•
If fuel spills, wait until it dries before you start the engine.
Fuel Filter, if installed
1.
Before you replace the fuel filter (A, Figure 19), drain the fuel tank or close the fuel
shut-off valve. If the fuel tank is not drained, fuel leakage can occur and cause a fire
or explosion.
2.
Squeeze the tabs (B, Figure 19) on the clamps (C) with pliers. Move the clamps
away from the fuel filter (A).
3.
Twist and pull the fuel lines (D, Figure 19) off of the fuel filter.
4.
Examine the fuel lines (D, Figure 19) for cracks or leaks. If it is necessary, replace
the fuel lines.
5.
Replace the fuel filter (A, Figure 19).
6.
Attach the fuel lines (D, Figure 19) with clamps (C).
