General Maintenance

MAINTENANCE

IMPORTANT!

MAINTENANCE, REPLACEMENT
OR REPAIR OF EMISSION CON-
TROL DEVICES AND SYSTEMS MAY
BE PERFORMED BY ANY REPAIR
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.
