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. Remove the air filter by unloosening the wing nut on top of
the cover then removing the wing nut on the filter. Pull the
filter straight up and check for dirt. Clean or replace the filter
element as needed. To clean wash the element in warm water
and mild detergent several times. Rinse and allow to dry. Soak
the filter in lightweight oil briefly, then shake out the excess.
Install the new or clean filter and secure the air cleaner cover.
Spark Plug Maintenance:
1. Disconnect spark plug wire from the end of plug. Clean out
debris from around the spark plug.
2. Using a spark plug wrench, remove the spark plug. If the spark
plug is oily, clean it with a 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.
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.
