MUFFLER

WARNING

•Inspect periodically, the muffler for loose fasten- ers, any damage or corrosion. If any sign of ex- haust leakage is found, stop using the machine and have it repaired immediately.

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

SPARK ARRESTER

•The muffler is equipped with a spark arrester to prevent red hot carbon from flying out of the exhaust outlet. Periodically inspect and clean as necessary with a wire brush.

ANGLE TRANSMISSION

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

•Remove the bolt of the grease nipple and the bolt opposite side of the grease nipple. Install new grease into the grease nipple to arrange for old grease to exit from the opposite side.

WARNING

BCZ4000DL / BCZ4000DW / BCZ4200CL

•	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	G
	before using it, check the area around the muffler and	B
	remove any wood chips or leaves which have attached
	themselves to the brushcutter. Failing to do so could
	cause the muffler 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 re-
	move the upper cover and the lower cover shown in in
	order to be able to view the upper 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 mechani- cal failure on the part of the brushcutter.

PROCEDURES TO BE PERFORMED AFTER EVERY 100 HOURS OF USE

1.Remove the muffler, insert a screwdriver into the vent, and wipe away any carbon buildup. Wipe away any carbon buildup on the muffler exhaust vent and cylinder exhaust port at the same time.

2.Tighten all screws, bolts, and fittings.

3.Check to see if any oil or grease has worked its way in be- tween the clutch lining and drum, and if it has, wipe it away using oil-free, lead-free gasoline.
