9. Maintenance

SPARK PLUG

•Starting failure and misfiring are often caused by a fouled spark plug. Clean the spark plug and check that the plug gap is in the correct range. For a re- placement plug, use the correct type specified by

KOMATSU ZENOAH.

0.6~0.7 mm

•REPLACEMENT PLUG IS A NGK BPMR7A.

IMPORTANT

•Note that using any spark plug other than those des- ignated may result in the engine failing to operate prop- erly or in the engine becoming overheated and dam- aged.

•To install the spark plug, first turn the plug until it is finger tight, then tighten it a quarter turn more with a socket wrench.

150 ~ 220 kgf-cm TIGHTENING TORQUE: (14.7 ~ 21.6 N.m.)

MUFFLER

WARNING

•Inspect periodically, the muffler for loose fasteners, any damage or corrosion. If any sign of exhaust leak- age is found, stop using the machine and have it re- paired immediately.

•Note that failing to do so may result in the engine catching on fire.

GEAR CASE

•The reduction gears are lubricated by multipurpose, lithium-based grease in the gear case. Supply new grease every 25 hours of use or more often depend- ing on the job condition.

•Remove the bolt opposit to the grease nipple before installing new grease to arrange for old grease to exit.

INTAKE AIR COOLING VENT

WARNING

•Never touch the cylinder, muffler, or spark plugs with your bare hands immediately after stopping the engine. The engine can become very hot when in operation, and doing so could result in severe burns.

•When checking the machine to make sure that it is okay before using it, check the area around the muffler and remove any wood chips or leaves w h i ch h av e a t t a ch e d t h e m s e l v e s t o t h e brushcutter. Failing to do so could cause the muf- fler to become overheated and that in turn could cause the engine to catch on fire. Always make sure that the muffler is clean and free of wood chips, leaves, and other waste before use.

•Check the intake air cooling vent and the area around the cylinder cooling fins after every 25 hours of use for blockage, and remove any waste which has attached itself to the brushcutter. Note that it is necessary to remove the engine cover shown in (MA5) in order to be able to view the up- per part of the cylinder.

IMPORTANT

•If waste gets stuck and causes blockage around the intake air cooling vent or between the cylinder fins, it may cause the engine to overheat, and that in turn may cause mechanical failure on the part of the brushcutter.
