3. Air Filter Service
A dirty air filter element will restrict air
flow to the carburetor, reducing engine
performance, if you operate the pump in
very dusty areas, clean the air filter more
frequently than specified in the maintenance
schedule.
NOTE: Never run the engine
without the air filter or use a
damaged air filter. If so, rapid
engine wear will result.
Screw off the butterfly nut down and remove
the housing. Screw off the other butterfly nut
and remove the element.
1. Wash the element with home detergents
and warm water (or non-flammable or high
flash-point cleansing solvents) and dry it up.
2. Soak it in clean engine oil until it is
saturated. Squeeze out excess oil.
3. Clean the lower body of the air filter,
housing, and rubber cushion. Prevent
dusts from entering into the ail path of the
carburetor.
4. Reinstall air filter and screw on the butterfly
nut.
4. Spark Plug Service
Recommended Groway plugs.
Wrong model can result in engine
damage.
1. Remove the spark plug cap, and clean any
dirt from around the spark plug base.
