General maintenancel

NOTE:
Using non-standard replacement
parts could invalidate your Shindaiwa
warranty.

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.
