Ending The Drilling Process - Baier BDB 825 Translation Of The Original Instruction Manual

EN
•
Open water supply slightly.
•
15 Press the ON / OFF switch (3) to switch
on the diamond drill and wait until the working
speed has been reached – green LED (1) lights
up.
WARNING
Risk of injury due to falling drill cores.
Î If drilling openings through objects, always
check the rooms below or behind and block off
the danger zone. Use formwork to secure the
drill core against falling.
NOTE
The diamond core drill bit can become blunt or
damaged due to overheating.
The feed may only be as high as the diamond
core drill bit can wear away the material. You
must therefore not exert too large a force on the
diamond core drill bit and avoid canting.
A suitable dust extractor must be connected to the
dry diamond drill.
•
Position the wet diamond core drill bit and drill
with a uniform, light feed pressure.
•
Always withdraw the diamond core drill bit
slightly in-between times, to rinse out the drilling
sludge.
•
15 If the feed is too fast, the red LED (2) lights
up. Then, reduce the feed immediately until the
green LED (1) lights up again.
If this warning signal is ignored, i.e. the feed
is not reduced, the electronics switch off the
diamond drill on overload.
The drilling process can then be started and
continued as described above.
NOTE
If the diamond drill is operated without water
extraction, you must ensure that the escaping
water is collected and does not cause any damage.

5.4.1 Ending the drilling process

•
After reaching the required drilling depth, slowly
withdraw the diamond drill with the wet diamond
core drill bit rotating slowly – the wet diamond
core drill bit still remains in the centring suction
plate.
•
After drilling, briefly let the water continue
running to flush out the drilling sludge between
the wet diamond drill bit and the drill core.
•
15 Release the ON / OFF switch (3), to switch
off the diamond drill.
•
Switch off the water supply and the water
extraction.
•
Pull the now stopped wet diamond core drill
bit out of the drill hole, and at the same time
remove the centring suction disc with it.
Remove drill core
NOTE
Risk of fracture of the diamond core drill bit's
cutting segments and/or damage to the drill.
Never use the diamond core drill bit to break out
the drill core!
•
16 Use a suitable tool (e.g. chisel) to break out
the drill core in the wall.
