Angle gear

The angle gear has two purposes:

The first is to gear down the engine’s high speed to better suit the lower speed a saw blade or trimmer requires to work efficiently.

Second, the angle gear contributes to the saw opera- tor’s working stance so that it is comfortable and at the same time efficient. The power from the engine, via the drive axle, shall in other words be angled so that the cutting equipment works parallel to the ground.

Dismantling

Remove the cutting equipment and guard.

Then loosen the bolts holding the angle gear against the shaft.

Remove the angle gear from the shaft.

Remove the circlip and washer on the output axle.
