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.

10. Storage

Aged fuel is one of major causes of engine starting fail- ure. Before storing the unit, empty the fuel tank and run the engine until it uses all the fuel left in the fuel line and the carburetor. Store the unit indoor taking necessary measures for rust prevention.

11. Disposal

When disposing your machine, fuel or oil for the machine, be sure to allow your local regulations.
