5.1

Drive wheel

The drive wheel is subject to wear because of the design of the drive. The V-shaped edge of the inside
diameter of the saw blade is pressed by the guide rollers into the V-shaped groove of the drive wheel.
When the saw blade touches the base of the V-shaped groove of the drive wheel, the saw blade slides.
In this case, the drive wheel must be replaced.
Replacing the drive wheel
Loosen the hexagon head screw [19] clockwise, using the combination spanner and face spanner (see
scope of delivery). Remove the drive wheel.
Observe the instructions for installing the drive wheel as described in point 4.7.
Hexagon head screw is provided with a left-hand thread!

Guide rollers

Lubricate guide sleeve
The guide sleeves on which the guide rollers are mounted must be lubricated regularly to allow easy
movement inside and out. If the guide sleeves cannot move easily, the saw blade can not be
sufficiently pressed against the drive wheel.
Remove saw blade and guide plate.
Fully loosen the adjusting knobs [10]. The guide sleeve is locked into the adjusting knob and follows
this when loosening. By completely loosening the adjusting knobs, the sleeves are released from the
knobs.
Remove guide sleeve completely to the front.
Clean guide sleeves and seat in gearbox housing and provide
water-resistant grease.
Screw the adjusting knobs and insert guide sleeves into the seat in
the gear housing. Push the guide sleeve into the adjusting knob by
hand until a clear snapping action can be heard.
The correct engagement can be checked by unscrewing the knob. If
the guide sleeve is correctly locked, the guide sleeve is carried away
by the adjusting knob.
If the guide sleeve is not correctly locked into the adjusting knob, the guide sleeve can
come loose during operation
