Prior to each work day, perform the
following:
Remove any dirt and debris from the
engine, check the cooling fins and air
cleaner for clogging, and clean them as
necessary.
Carefully remove any accumulations of
dirt or debris from the muffler and fuel
tank. Dirt buildup in these areas can
lead to engine overheating, premature
wear or fire.
Check for loose or missing screws or
components. Make sure the trimmer
head is securely fastened.
Check the unit for leaking fuel or
grease.
Every 10 hours of operation…
(more frequently in dusty or dirty
conditions):
Remove the air cleaner element from
the carburetor and wash it with soap and
water. Rinse the element thoroughly with
clean water.
Squeeze out the water and allow the
element to dry before reinstalling.
Remove and clean the element

Figure 21
Every 10 to 15 hours of operation:
Remove and clean the spark plug. Adjust
the spark plug electrode gap to 0.04-inch
(0.6 mm). If the plug must be replaced, use
only a Champion CJ8 or equivalent type
spark plug of the correct heat range. For
Electromagnetic Compliance (EMC) use
NGK BMR6A. See Figure .
Clean the spark plug and
check the gap at the electrode.
0.024 inch
(0.6 mm)
CAUTION!
Before removing the spark plug, clean
the area around the plug to prevent
dirt and debris from getting into the
engine’s internal parts.
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
maintnenance work.
Hard starting or a gradual loss of
performance may be caused by carbon
deposits lodged in the muffler’s
spark arrester screen. In such cases,
performance can usually be restored by
removing the spark arrester screen and
giving it a thorough cleaning with a stiff
bristle brush.
In case of heavy carbon deposits or when
there is no improvement in performance
after cleaning the spark arrester screen,
consult with your nearest Shindaiwa
dealer.
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.
