Servicing the Air Filter

WARNING
Fuel and its vapors are extremely flammable and
explosive.
Fire or explosion can cause severe burns or death.
• Never start or run the engine with the air cleaner
assembly or air filter 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.
1. Remove the fasteners (A, Figure 12) and the air filter
cover (B).
2. To remove the filter (C), lift the end of the filter and then
pull the filter off the intake (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 to the filter.
6. Install the filter on the intake. Push the end of the filter
into the base as shown. Make sure filter fits securely in
the base.
7. Install air filter cover and secure with fasteners.
Check Spark Plug Gap
Use a spark plug feeler gauge to check the gap between the
two electrodes. When the gap is correct, the gauge will drag
slightly as you pull it through the gap (see Figure 13).
If necessary, use the spark plug gauge to adjust the gap by
gently bending the curved electrode without touching the
center electrode or the porcelain.
Install Spark Plug
Finger tighten, then tighten with wrench (see Figure 14).

WARNING
Replacement parts must be the same position as the
original parts or fire could result.
To service the muffler, see an authorized dealer.

CAUTION: Spark plugs have different heat ranges. It is
important that the correct spark plug is used, otherwise,
engine damage can occur.
