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 pressurized water tank (No. FF35028) or con-
necting 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)
 Use the adjusting screws to fix both arms of the water extraction ring (No. 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 extractor.
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 (1).
 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!
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 electronically automatic switch off 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)
 Switch on the motor.
 Apply the diamond drill bit and continue to drill using light, consistent follow-up pressure.
 Occasionally with draw the drill bit slightly from the bore so that the drilling mud or dust is
removed.
 Shut down the motor once the desired drilling depth has been achieved and pull the drilling
bit out of the borehole slowly.
 Stop the supply of water and shut down the water extractor.
 If no more boreholes are required, allow the motor to run again for a few seconds without
water supply in order to press the remaining water out of the rinsing bush of the motor.
