Engine Operation

Oil draining, and
checking oil level
WARNING: Burn hazard
Never open oil port while engine is running. Hot oil can spray over face and
body.
1. Operate the water pump for 3 to 5 minutes to
thin oil for easier draining.
2. Ensure that the engine is stopped and on a level
surface.
3. Remove the drain bolt and washer; drain the oil
into an approved container.
4. Reinstall washer and drain bolt.
5. Remove the dipstick and clean it.
6. Fill crankcase with oil to the bottom lip of the oil filler neck.
7. Reinsert the dipstick into the oil filler without threading in, and check oil level.
If the oil level is too low, add recommended engine oil to the oil filler neck.
8. Reinstall the dipstick.
Spark plug
removal, cleaning
and replacement
Proper spark plug clearance ensures the engine’s normal running.
a) Remove the spark plug cap.
b) Remove the spark plug using the supplied spark plug wrench.
WARNING
Be careful not to touch the muffler during or just after the engine has been
running.
c) Clean the spark plug with a steel brush. If the insulator is damaged, replace the
spark plug.
d) Measure the spark plug clearance with a feeler. The clearance should be 0.7-
0.8mm. If adjustment is necessary, bend the side electrode carefully.
e) Check if the spark plug gasket is in good conditions, or replace with a new
one. Screw on the spark plug to the bottom first by hand and then tighten it up
by a spark plug wrench. If a new spark plug is used, twist 1/2 more turns after
impacting the gasket; if reinstall the original one, just twist 1/8-1/4 more turns.
