4 Gear selector switch
4.2 Start of operation (B)
Clamping into the drill rig (picture 1)
 Remove the feed gear from the drill rig.
 Fasten the feed gear to the drill motor by means of the screws and a T-handle with ball end
attached to the drill rig.
Please pay attention to the correct position of the feather key groove, bores and
fitting position.
 Slide the motor together with the feed gear from the top into the guideway on the drill rig.
 Check the tight fit of the motor.
For this please read the drill rig instruction manual!
Changing the drill bit (picture 2)
Please wear protective gloves when changing the drill bit. The drill can become
hot after being in use for a longer period of time.
 Use an open-ended spanner (SW 36) to hold the drive shaft (1) and release and unscrew
(right-hand thread) the drill bit using an open-ended spanner (SW 24 for G 1/2" bits; SW 41
for 1.1/4" UNC bits).
Information: In the case of drill bits with a 1.1/4" UNC screw thread it is recommended to place
a copper ring (No. FF35190) between the drill motor and the drill bit. It is then easier to separate
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 wastewater pump (No. FF35029),
pressurized water tank (No. FF35026) 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)
 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 (No. FF35210).
Concerning this, please read the operating manual for the submersible water pump, 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. FF35148) to the mains supply.
For this please read the vacuum cleaner instruction manual!
