Drill bit extension
When you need to drill deeper than the usable length of your drill bit is:
§
First, only drill to the point the usable length of the bit reaches.
Remove the bit and pull the centre core out of the hole without
§
moving the core drilling unit.
§
Push the drill bit back into the bore hole.
Screw an adequate extension between drill bit and motor. If the collet of the
drill bit is 1 ¼" , please do not forget the copper rings which make the removal
of the drill bit easier.
Always use drill bits which match the material which has to be drilled.
You can prevent the machine from damage if you only use drill bits which
are balanced and not deformed. Pay attention that diamond segments have
enough relief cut towards the drill bit body.
Overload Protection
In order to protect the operator, motor and drill bit, the DB 200 GR is
equipped with a mechanical and electronic overload protection.
Mechanical:
If the drill bit is suddenly blocked in the hole, a clutch will slip
disengaging the drill spindle from the motor.
Electronic:
In case of overload due to too large feed force, the motor
cuts off automatically. After discharge, switching OFF and
ON again, drilling can be continued.
Safety Clutch
The safety clutch should absorb shock and excessive stress.
To keep it in good condition, the clutch should slip for a very short
time (max. 2 seconds) in each case only. 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!
