Daily maintenance
Prior to each work day, perform the
following:
■
Remove all dirt and debris from the
engine, check the cooling fins and
air cleaner for clogging, and clean
as necessary.
■
Carefully remove any accumulations
of dirt or debris from the muffler
and fuel tank. Check cooling air
intake area at base of crankcase.
Remove all debris. Dirt build-up
in these areas can lead to engine
overheating, fire, or premature wear.
WARNING!
Always wear gloves
when working around the cutter
assembly.
■
Clean any debris or dirt from the
cutting attachment.
■
Check for loose or missing screws
or components. Make sure the
cutter attachment is securely
fastened.
WARNING!
Before performing any
maintenance, repair, or cleaning
work on the unit, make sure the
engine and cutting attachment are
completely stopped. Disconnect
the spark plug wire before
performing service or maintenance.
Muffler
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
connections tight and clean.
Fasteners
Make sure nuts, bolts, and screws
(except carburetor adjusting screws)
are tight.
Cooling
fins
Remove all dirt and debris from the engine and check the cooling fins
■
Check the entire unit for leaking fuel
or grease.
■
Make sure nuts, bolts, and screws
(except carburetor idle speed
adjusting screws) are tight.
WARNING!
Non-standard accessories,
cutting attachment, or replacement
parts may not operate properly with
your unit and may cause damage
and lead to personal injury.
Air Filter
The H4 engine that powers your
Shindaiwa model is a hybrid 4-stroke
engine. As a hybrid, the engine is
lubricated 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.
