Oil Service
•
Check oil level regularly.
•
Be sure correct oil level is maintained.
Check every five to ten hours before
starting engine. See oil checking
procedure in the Set-Up section.
Oil Drain
IMPORTANT:
Be sure to check engine on a level
surface with the engine stopped. Drain the oil
while the engine is still warm to assure rapid
and complete draining.
1.
Locate the oil drain valve (a) and place a
suitable container below the plug.
2.
Remove the drain cap (b).
NOTE:
If necessary, push the oil drain hose (if
provided) onto the oil drain valve. Route the
opposite end of the hose into an appropriate
oil collection container with at least a 2.5 quart
capacity, to collect the used oil.
3.
Turn the drain plug valve 1/4 turn
counterclockwise while gently pulling
the valve away from the engine to open
the oil drain valve.
4.
Allow oil to drain into a suitable
container.
5.
Reverse STEPS 4-3 to close the oil drain
valve and reinstall the drain cap.
IMPORTANT:
Used motor oil may cause skin
cancer if repeatedly left in contact with the skin
for prolonged periods. Although this is unlikely
unless you handle used oil on a daily basis, it is
still advisable to thoroughly wash your hands
with soap and water as soon as possible after
handling used oil.
NOTE:
Please dispose of used motor oil
in a manner that is compatible with the
environment. Check with your local municipality
for proper disposal procedure. Do not throw it
in the trash or pour it on the ground.

WARNING
: Shut off the engine
before performing any maintenance.
To prevent accidental start-up,
disconnect the spark plug boot.
Periodic inspection and adjustment of the
engine is essential if high level performance
is to be maintained. Regular maintenance will
also ensure a long service life. The required
service intervals and the kind of maintenance
to be performed are described in the table
below. Follow the hourly or calendar intervals,
whichever occur first. More frequent service is
required when operating in adverse conditions.
WARNING
: If the engine has been
running, the muffler will be very hot. Be
careful not to touch the muffler.
