the drill bits from the motor after drilling and any unevenness between the drill bit fitting and the
drive shaft is compensated.
Wet drilling (picture 3)
Wet drilling is only permitted with a faultless "PRCD". Always carry out work using a
water extraction device when wet drilling overhead. Protect the prime mover from splash
water.
 Water connection: Water connection (6) to a submersible pressurized water tank (No.
FF35028) or connecting a water line directly over a Gardena water hose (7) using a two way
adapter.
(There must at least be sufficient water pressure (max. 4 bar!) to move the arising drilling
mud from the borehole)
 Operation in the drill rig: Use the adjusting screws to fix both arms of the water extraction
ring (No. FF35700, FF35730) to the base plate. Cut a hole into the rubber sheet somewhat
larger than the diameter of the drill bit. Connect the water extraction ring to the water extrac-
tor.
Concerning this, please read the operating manual for the pressurized water tank or the water
extractor appliance!
Optional: Dry drilling (picture 4)
 Screw the suction rotor (No. FF40056) onto the drive shaft (8).
 Attach the hose adapter and suction hose.
 Connect the vacuum cleaner (No. FF35144) to the mains supply.
For this please read the vacuum cleaner instruction manual!

Handling

Please read and be sure to understand the drill rig instruction manual for operation in the
drill rig.
Overload protection
The green control lamp illuminates during normal operation. The red control lamp illuminates if
excessive pressure is applied to the drill bit. Reduce the contact pressure; the green control
lamp illuminates again.
The electronic system shuts the equipment down in the case of overloading for a longer period
of time. Switch the equipment off and then on again in order to continue working. In the event of
jerky overloading (e.g. jamming of the drill bit) the friction coupling interrupts the force flow.
Setting the speed
 Set the speed according to the diameter and the type of the material, according to the label.
Only change gears when the equipment is at a standstill.
Wet drilling
Danger due to electric shock! Always carry out work using a water extraction device when
wet drilling overhead. The water extraction device must be in a flawless condition.
 Turn on the water connection and switch on the water extractor.
(There must at least be sufficient water pressure (max. 4 bar!) to move the arising drilling
mud from the borehole)
 Freehand operation wet suction: Insert the drill bit into the water suction ring while it is sta-
tionary and check before whether the water suction device has been firmly stuck by suckers
to the wall or the floor and is being held firmly.
Please note: Never drill from the bottom up when using the centering aid in order to avoid
the danger of an accident in the event of unintentional release of the centering aid. The
water suction ring can come loose during drilling!
 Switch on the motor.
 Apply the diamond drill bit and continue to drill using light, consistent follow-up pressure.
