Safety Instructions; Switching On/Off; Overload Protection - Carat A-2012 Manuel D'utilisation

Safety instructions

•
Attention: Because of the high torque in the lowest gear, we strongly advise you not to drill by hand in the lowest gear. If
the diamond drill suddenly gets stuck there is a high risk that the user will get hurt. Use lowest gear only in combination
with a drill rig.
•
Plug in the machine only when it is switched off
•
Prevent water with electricity through slippage, leaking, or dripping from the hose
•
A water catchments ring must be used when drilling above the head.
•
Remove water safely using a water pump
•
The drill machine may not become damp
•
Always use the extra side handle provided and always hold the drill machine with both hands
•
Always use the machine under supervision. Keep hands away from rotating parts
•
Ensure you are always standing firmly during drilling.
•
Wear prescribed and suitably protective clothing
•
Due to the creation of dust particles, the use of a dust mask is recommended.
•
Double-check that the diamond drill is correctly assembled
•
Before use, check that all screws are firmly in place. Because of vibrations caused during drilling, screws can work loose
and cause damage or injury
•
After use, do not touch metal parts of the drill machine and the diamond drill; this could be hot and cause burns.
•
Ensure that the drill machine does not start rotating by accident; always disengage the switch when disconnecting from the
power source, or if there is an interruption to the power supply
PRCD switch
The A-2012 electrical cable is equipped with a PRCD switch which protects the operator against electrocution. As soon as the
drilling machine is plugged in, the PRCD should be started up by pressing on the (green) –RESET button. If the PRCD is switched
off , the –RESET button must be pressed again.
Note:
•
The PRCD and the electrical cable should never come in contact with water
•
Check the PRCD by pressing the –TEST button before use.
•
Never use the diamond drilling machine without a properly functioning PRCD
•
Never replace the standard plug with another type of plug
Extra Side handle
The side handle can be loosened by hand to change its position. After position is set , twist the handle again until firm.
By removing this handle, it is possible to mount the drilling machine in a drilling rig with a collar of ø 60 mm

Switching on/off

The machine is provided with a switch with a fix button, with which the machine can be switch on/off in 2 ways:
1 – Moment switch
Switch on: push in switch
Switch off: release switch
2- Permanent switch
Switch on: push in switch and secure using fix button (for use in a drill standard )
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 flashing.
The pressure on the diamond drill bit must than be reduced.
When the motor is overloaded too long, the LED flashes 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.
