Environmental Protection; Declaration Of Conformity - Carat A-16 Manual

Switch off; release switch and release again
Overload protection
To protect the motor, operator and diamond drill, the
machine is provided with a mechanical, electronic and
thermal overload safety system. Whenever the engine is
switched off due to overload, it must be switched on again
as soon as possible to cool the engine. Then let the drill
turn for a minimum of 1 minute.
1 - Electronic / Thermal
Whenever the engine is heavily overloaded , the overload
indication (LED) on top of the handle will start fl ashing.
The pressure on the diamond drill bit must than be reduced.
When the motor is overloaded too long, the LED fl ashes
continuously and the machine will switch off automatically.
2 - Mechanical
If the drill bit suddenly gets stuck, the slip coupling is
activated to disconnect the main axis from the engine.
Make sure you switch off the engine immediately and
remove the drill from the hole. When the slip coupling is
activated for a longer periods, the mechanical slip must be
re-tuned by a recognised expert.
Drilling with water cooling - Water connection
IF APPLICABLE
The drilling machine is equipped with a water tap, which
includes a 'Gardena' connection. Make sure that the core
drill is suffi ciently cooled and that the slurry is properly
discharged. The maximum permitted water pressure is 3
bars. Always use clean water to enlarge the life span of
the internal water seals. In case of leakage, the drilling
machine has to be checked IMMEDIATELY by a certifi ed
mechanical expert.
Dry drilling - Dust Extraction
IF APPLICABLE
For dry drilling only use designated drill bits. Dry drilling is
only possible in masonry, brick/block and sandstone.
Dust released during dry drilling is dangerous to your
health. Therefore a dust extraction system specially
intended for this purpose must be used, and if necessary,
a dust mask worn. The use of a dust extraction system
is also required to optimize the life time of the diamond
drill bit. To prevent clogging of the dust extraction system
it is essential that the materials which are being drilled are
completely dry. Information about dust extraction systems
is available at your diamond tools supplier.
Dustec ® dust extraction
The A-1810 is equipped with an integrated Dustec ® dust
extraction system which is only suitable for Dustec ® drill
bits (with dust holes in top fl ange) of max. 82 mm and M16
(F) connection.
The drill bit can be mounted directly on the shaft. To
remove the drill bit push the fi x button on top of the motor
housing an put a spanner 24-trhough the hose connection-
on the drill bit ad loosen it. The dust released during drilling
is dangerous to your health. The A-1810 is therefore only
to be used in combination with a suitable vacuum cleaner
which is fi xed to the hose connection on the Dustec®
system.

NASTROC ® system
The A-1821 is equipped with the robust NASTROC ®
system and the diamond drill can be changed without
using other tools. The lock nut has to loosened, so that
the diamond drill with NASTROC ® connection can be
assembled.
