First of all, the detachable hood
segment has to be removed. The snap
fit opens up and the segment is pushed
forward. Now you can hold up the
driving disc between gearbox and
grinding wheel by using a jaw wrench
32 (1). Use the face spanner (2) to
unscrew the driving nut. Then remove
the mounted grinding wheel
respectively mount the new one.
The assembly works the other way
round!
Let the machine run for a short period of time and in a safe position. If the
machine does not run easily, stop working immediately.
Use only original accessory!
Dust Extraction
Dust which occurs during your work is hazardous to health. That is why the
concrete grinder must be used with a vacuum cleaner, and a dust mask
has to be worn. The suitable Wet/Dry Vacuum Cleaner is available as
accessory. It can directly be attached to the connection on the dust hood.
Changing the brush rim
If the length of the brushes is
– due to wear - smaller than 5 mm (extreme
formation of dust during grinding), the brush rim has to be replaced
completely.
Therefore, remove the three fixing screws of the firm part of the dust guard
and the two fixing screws of the detachable part. Pull out the worn brush
rim and replace it by a new one. Pay attention that the fastening holes in
the brush rim and the holes of the dust hood have the same same position.
Screw both parts together.
