Mufer
This unit must never be operated with
a faulty or missing spark arrester or
muffler. Make sure the muffler is well
secured and in good condition. A worn
or damaged muffler is a fire hazard and
may also cause hearing loss.
Spark Plug
Keep the spark plug and wire connec-
tions tight and clean.
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 filter 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 adjustments. To
keep your H4 engine strong and reliable,
Shindaiwa recommends that you check
and service the air filter as instructed in
the 10-Hour Maintenance section that
follows.
Check for loose or missing screws or ■
components. Make sure the cutter
attachment is securely fastened.
Check the entire unit for leaking fuel
■
or grease.
Make sure nuts, bolts, and screws
■
(except carburetor idle speed adjust-
ing screws) are tight.
Fasteners
Make sure nuts, bolts, and screws
(except carburetor adjusting screws)
are tight.
