ESTABLISHMENT OR INDIVIDUAL;
HOWEVER, WARRANTY REPAIRS
MUST BE PERFORMED BY A DEALER
OR SERVICE CENTER AUTHORIZED
BY SHINDAIWA KOGYO CO., LTD.
THE USE OF PARTS THAT ARE NOT
EQUIVALENT IN PERFORMANCE AND
DURABILITY TO AUTHORIZED PARTS
MAY IMPAIR THE EFFECTIVENESS OF
THE EMISSION CONTROL SYSTEM
AND MAY HAVE A BEARING
ON THE OUTCOME OF A
WARRANTY CLAIM.
NOTE:
Using non-standard replacement
parts could invalidate your Shindaiwa
WARNING!
Non-standard parts may not operate
properly with your unit and may cause
damage and lead to personal injury.
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 mainte-
nance work.
Blades
Keep blades sharp and check blade
condition frequently. If a blade’s per
-
formance changes suddenly, stop the
engine and check the blade for cracks
or other damage. Replace a damaged
blade IMMEDIATELY!
WARNING!
■ Never repair a damaged blade
by welding, staightening, or by
modifying its shape. An altered
blade may break during opera-
tion, resulting in serious personal
injury.
■ DO NOT use 2-tooth or NON-
Shindaiwa approved 4-tooth
cutting blades on Shindaiwa trim-
mers or brushcutters.
■ Blades are not interchangeable
between Shindaiwa edgers and
trimmer/brushcutter models.
Operating any unit with a blade or
attachment not approved for that
unit can be hazardous and may
cause serious injury.
Spark Plug
Keep the spark plug and wire connec-
tions tight and clean.
Fasteners
Make sure nuts, bolts, and screws
(except carburetor adjusting screws)
are tight.
Daily Maintenance
Prior to each work day, perform the
following:
■ Check for loose or missing screws
or components. Make sure the tool
and cutting attachment are securely
fastened.
■ Check the entire unit for leaking fuel or
grease.
■ Remove dirt or debris from the engine,
check the cooling fins and air cleaner
for clogging and clean them as neces-
sary.
■ Carefully remove any accumulation of
dirt or debris from the muffler
or the fuel tank. Dirt build-up in these
areas could cause the engine overheat
-
ing, induce premature wear, or create a
fire hazard.
Remove and clean
or replace the element
10 hour Maintenance
Every 10 hours of operation
(more frequently in dusty or dirty
conditions):
Remove the air cleaner element.
See Figure 27. Clean or replace as
necessary. To clean element: Wash it
thoroughly in soap and water. Let it
dry before reinstalling the element.
CAUTION!
Do not operate the unit if the air
cleaner or element is damaged, or if
the element is wet.
10/15 hour Maintenance
Every 10 to 15 hours of operation:
Remove and clean the spark plug.
Adjust the spark plug electrode gap
to 0.024-inch (0.6 mm). If the spark
plug must be replaced, use only a
Champion CJ8Y or equivalent spark
plug of the correct heat range. (For
electro magnetic compliance (EMC)
use an NGK BMR6A resistor plug.)
CAUTION!
Before removing the spark plug, clean
the area around the plug
to prevent dirt and debris from getting
into the internal engine parts.
Clean the spark plug
and check the gap at the
electrode.
