Safety Clutch
The safety clutch should absorb shock and excessive stress. It is an aid and
not an absolute protection. Therefore you have to handle and drill carefully.
To keep it in good condition, the clutch should slip for a very short time
(max. 2 seconds) in each case only. Slipping for longer periods destroys
the safety clutch. After excessive wearing the clutch has to be renewed
by an authorized service shop.
Fracture of Segment
If a diamond segment, parts of the armouring or something simliar break out
while drilling, and consequently the drill bit seizes, stop working on this bore
and drill a hole having the same centre and a diameter being 15 – 20 mm
bigger.
Do not try to finish your work using another drill bit of the same
diameter!
After Drilling
When you have finished drilling:
Pull the drill bit out of the hole.
Turn the motor off by using the motor switch and not the PRCD switch.
Close the water supply.
Removal of the core when it sticks in the drill bit:
Separate the drill bit from the motor (if possible).
Put the drill bit in a vertical position.
Knock carefully on the pipe by using a wooden hammer shank till the
drilling core slips out. Never throw the drill bit against a wall by force or
set about it with tools, such as hammer or jaw wrench. Otherwise, the
pipe could go out of shape and neither the drilling core can be extracted
nor the drill bit is reusable.
Removal of the core by blind holes:
Break off the core with a cotter or lever, or in pieces. Lift the core out with
appropriate tongs or drill a hole with a dowel in the core, screw an eyebolt in
and pull the core out.
