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 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.

Blades

Keep blades sharp and check blade condition frequently. If a blade’s perfor- mance changes suddenly, stop the engine and check the blade for cracks or other damage. Replace a damaged blade

IMMEDIATELY!

WARNING!

nNever repair a damaged blade by welding, straightening, or by modify- ing its shape. An altered blade may break during operation, resulting in serious personal injury.

nBlades are not interchangeable between Shindaiwa edgers and trim- mer/brushcutter models. Operating any unit with a blade or attachment not approved for that unit can be haz- ardous and may cause serious injury.

Daily Maintenance

Prior to each work day, perform the following:

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

nCarefully 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.

nCheck for loose or missing screws or components. Make sure the cutting at- tachment is securely fastened.

nCheck the entire unit for leaking fuel or grease.
