Spark Plug Maintenance
Disconnect spark plug wire from1.
end of plug. Clean out debris from
around spark plug.
Using a spark plug wrench, remove2.
the spark plug.
Inspect the spark plug:3.
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, the spark plug needs to be
replaced.
When installing a new spark plug, ad-4.
just the plug’s gap to the specication
on the Technical specication chart
(page 14). Do not pry against the
electrode or the insulator, the spark
plug can be damaged.
Install the new spark plug or the5.
cleaned spark plug into the engine.
Gasket-style: Finger-tighten until the
gasket contacts the cylinder head,
then about 1/2-2/3 turn more.
Non-gasket-style: Finger-tighten until
the plug contacts the head, then
about 1/16 turn more.

WARNING! TO PREVENT
SERIOUS INJURY FROM
FIRE:
Replace the fuel lter in a
well-ventilated area away from igni-
tion sources. Do not smoke.
Wait for engine to cool completely1.
before proceeding.
Wear protective gear including, ANSI-2.
approved safety goggles, NIOSH-
approved dust mask/respirator, and
nitrile gloves.
Close fuel valve leading from gas3.
tank completely.
Take note of the fuel lter’s orienta-4.
tion.
Place a suitable container under the5.
fuel lter.
Disconnect the fuel lines leading to6.
and from the fuel lter and allow fuel
to drain onto the container.
Install new fuel lter in the same 7.
orientation. Make sure to properly
secure both fuel lines.
Clean up and properly dispose of all8.
fuel.
Wait for at least one hour before use9.
to allow all residual fuel vapors to
dissipate. To prevent FIRE, do not
start the engine while the smell of
fuel hangs in the air. Remember to
open the fuel valve before restarting
the engine. It may take a little longer
than usual to start the engine be-
cause the fuel needs to rell the fuel
line and new lter.

for longer than 20 days, prepare the
engine for storage as follows:
Change engine oil and empty fuela.
tank.
Either leave fuel tank empty orb.
rell fuel tank with fresh unleaded
gasoline mixed with a fuel stabilizer
intended for long term engine stor-
age (not included). After lling, run
engine for about 3-5 minutes to cir-
culate the treated gasoline through
the carburetor. Wait for engine to
cool before proceeding.
Clean out area around spark plug.c.
Remove spark plug and pour one
tablespoon of engine oil into cylinder
through spark plug hole.
Reinstall spark plug, but leave sparkd.
plug wire disconnected.
Pull recoil starter to distribute oil ine.
cylinder. Stop after one or two revo-
lutions when you feel the piston start
the compression stroke (when you
start to feel resistance).

age, keep in mind that untreated gas-
oline will deteriorate quickly. Drain
the fuel tank and lter, and change
to fresh fuel if untreated gasoline has
been sitting for a month, if treated
gasoline has been sitting beyond the
fuel stabilizer’s recommended time
period, or if the engine does not start
properly.
