Air Filter
The H4 engine that powers your
Shindaiwa model is a hybrid 4-stroke
engine. As a hybrid, the engine is lubri-
cated by oil mixed with the gasoline
and air from the carburetor that moves
through and around the internal parts
of the engine in a similar way that a
2-stroke engine is lubricated. Without the
heavy duty 2-stage air lter equipped on
all H4 engines, dust and dirt could also
move through the engine, decreasing
engine life, increasing valve wear and
the need for more frequent valve adjust-
ments. To keep your H4 engine strong
and reliable, Shindaiwa recommends
that you check and service the air l-
ter as instructed in the 10-Hour Mainte-
nance section that follows.
Check the entire unit for leaking fuel ■
or grease.
Make sure nuts, bolts, and screws
■
(except carburetor idle speed
adjusting screws) are tight.
