The angle gear has two purposes:
The fi rst is to gear down the engine's high speed to better suit the lower speed a saw blade or
trimmer requires to work effi ciently.
Secondly, the angle gear contributes towards the operator's working stance so that it is comfor-
table and at the same time effi cient. In other words, the power from the engine via the drive axle
should be angled so that the cutting tool works parallel with the ground.
