3. Place a 2 quart minimum capacity container under the
end of the oil drain (Figure 20).
4. Remove or open the oil drain plug (A or B, Figure

drain plug, and wipe up any oil that may have spilled.

Service Air Filter

!
Fuel and its vapors are extremely flammable and explo-
sive.
Fire or explosion can cause severe burns or death.
• Never start or 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.
!
The air filter system uses either a flat or a cylindrical car-
tridge air filter. Some models are also equipped with a pre-
cleaner that can be washed and reused.
Flat Air Filter
1. Pull up on the cover handle (A, Figure 22). Rotate the
cover handle toward the engine and then remove the
cover (B).
2. Remove the pre-cleaner (C, Figure 22), if equipped,
and the filter (D).
3. To loosen debris, gently tap the filter on a hard surface.
If the filter is excessively dirty, replace with a new filter.
4. Wash the pre-cleaner in liquid detergent and water.
Then allow it to thoroughly air dry. Do not oil the pre-
cleaner.
5. Assemble the dry pre-cleaner and the filter into the
engine base (E, Figure 22).
6. Align the tabs (F, Figure 22) on the cover with the
slots (G) in the blower housing. Rotate the cover han-
dle back and push down to lock in place.
Cylindrical Cartridge Air Filter
1. Remove the fasteners (A, Figure 23) and the air filter
cover (B).
