Maintenance
TO PREVENT SERIOUS INJURY FROM
ACCIDENTAL STARTING TURN THE POWER
SWITCH OF THE ENGINE TO ITS “OFF” POSITION.
Wait for the engine to cool, and remove the spark plug wire
before performing any inspection, maintenance, or cleaning
procedures.
Changing /Cleaning the Air Filter
1. Wipe off the air cleaner cover. Loosen the knob at the bottom
of the air cleaner housing
(see Figure 6).
2. Remove the air cleaner filter and deflecting plate.
3. Wash the air filter in warm water and mild detergent several
times. Rinse. Squeeze out excess water and allow it to dry
completely. Soak the filter in lightweight oil briefly, then
squeeze out the excess oil.
4. Install a new air filter or reinstall the cleaned air filter. Secure
the air cleaner cover before use.
Spark Plug Maintenance:
1. Disconnect spark plug wire from end of plug. Clean out debris
from around the spark plug.
2. Using the spark plug wrench provided, remove the spark plug.
Inspect the spark plug. If the electrode is oily, clean it using
a clean, dry rag. If the electrode has deposits on it, polish it
using emery paper. If the white insulator is cracked or chipped,
replace the spark plug.
3. When installing a new spark plug, adjust the plug’s gap to the
specification on the technical specification chart. Do not pry
against the electrode or the insulator, the spark plug can be
damaged (see Figure 7).
4. Install the new spark plug or the cleaned spark plug into the
engine. Gasket style spark plugs should be finger-tightened
until the gasket contacts the cylinder head, then turned about
1/2 to 2/3 more rotation. Non-gasket-style spark plugs should
be finger-tightened until the plug contacts the head, then
about 1/16 turn more.
