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 condi- tion frequently. If a blade’s performance 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, staightening, or by modifying its shape. An altered blade may break during opera- tion, resulting in serious personal injury.

nDO NOT use 2-tooth or NON- Shindaiwa approved 4-tooth cutting blades on Shindaiwa trim- mers or brushcutters.

Daily Maintenance

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 the engine over- heating, induce premature wear, or create a fire hazard.
