2) Maintenance of air cleaner
A dirty air cleaner can restrict air flowing into the carburetor. To keep
the carburetor in good working conditions, please service the air cleaner
periodically. If operating the engine in extremely dusty area, the job
should be done more often.
Never clean the air cleaner element with gasoline or low flash-point
detergents, or explosion may happen.
Never run the engine without an air cleaner, because air with dirt
and dust entering the engine can speed up the engine wear.
( 1) Remove the air cleaner cover off and take the element out.
(2) Paper element: Wash the element with home detergents and warm
water (or non-flammable or high flash-point cleansing solvents) and
dry up.
Foam element: Soak in clean engine oil until saturated. Squeeze out
excess oil, otherwise, the engine will smoke in starting stage.
(3) Clean the air cleaner cover and inner surface with wet cloth, be
careful not to allow the dust entering into the carburetor.
(4) Reinstall the element and put the air cleaner cover on.
3) Spark plug
Spark plug type: BPR6ES (NGK) or NHSP LD F7RTC
In order to ensure the engine normal running, gap of the spark plug must
be correct and no deposit around the spark plug.
(1) Remove the spark plug cap.
