Angle gear
Dismantling
Remove the angle gear from the shaft.
Dismantling
1. Remove the cutting equipment and
guard.
2. Remove the screw (A) and lift off
the plate (B).
3. Loosen the screw (C) holding the
angle gear on the shaft and
remove the 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.
Secondly, the angle gear contributes towards the operator’s working stance so that it is comfortable and at the same
time efficient. 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.
Remove the circlips holding the
bearings on the input respective output
shafts.
Heat the entire angle gear to approx.
110°C and first dismantle the input axle
and then the output axle.
4. Remove the support washers and the
dust protection disc.
5. Remove the circlips holding the
bearings on the output axle
(illustrated) and on the input axle
using the circlip pliers.
Heat the entire angle gear using a hot
air gun to approx. 110°C.
Knock the gear against a wooden block
so that the input axle and the bearing
fall out.
Now lift out the output axle.
Wear protective gloves.
