General 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.

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.

Daily Maintenance

WARNING!

Non-standard parts may not operate properly with your unit and may cause damage and lead to personal injury.

NOTE:

Using non-standard replacement parts could invalidate your Shindaiwa

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.

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.

10 hour Maintenance

■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.

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.

0.024"	Clean the spark plug
(0.6mm)	and check the gap at the

electrode.
