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 OUT- COME OF A WARRANTY CLAIM.

Daily Maintenance

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 work.

WARNING!

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

NOTE:

Using non-standard replacement parts could invalidate your Shindaiwa warranty.

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.

Prior to each work day, perform the following:

. Remove dirt or debris from the engine, check the cooling fins and air cleaner for clogging and clean them as necessary.

10-Hour Maintenance

(more frequently in dusty conditions)

. Remove the air filter cover by loosening the two thumbscrews. See Figure 13A.

. Remove and inspect the pre-filter. If the pre-filter is torn or otherwise dam- aged, replace it with a new one. See Figure 13B.

3.Clean the pre-filter with soap and water. Let dry before reinstalling.

4.Inspect the air filter element. If the ele- ment is damaged or distorted, replace it with a new one.

5.Tap filter gently on a hard surface to dis- lodge debris from element or use com- pressed air from the inside to blow debris out and away from the air filter element.

IMPORTANT!

Direct the air stream at the inside face of the filter only!

. Carefully remove any accumulation of dirt or debris from the muffler or the fuel tank. Dirt build-up in these areas could cause engine overheating, induce premature wear, or create a fire hazard.
