5. Press on TEST. The orange indicator switches itself off.
6. Press on RESET to switch the device on (ORANGE).
These protective device protect against faults in the attached device, not against such
faults in the preceding plant.
4 Function of the Unit
4.1 Overview (A)
1 Drill rig fitting 6 Water connection
2 Overload protection indicator 7 “Gardena“ water connection
3 Power cable with PRCD switch 8 Drive shaft
4 On/off switch 9 Hand grip
5 Gear selector switch
4.2 Start of operation (B)
Freehand operation
 Only work with the moment switch, i.e. without locking the on/off switch.
 The additional hand grip (9) can be fasted on the left or on the right.
Great moments of force are generated when drilling using drill bits; never work
without the additional hand grip.
Clamping into the drill rig (picture 1)
 Locate the feed gear in position on the drill rig.
 RODIACUT 170 PRO: Insert the motor into the receptacle of the drill rig from the top and
fasten by means of the screws (size 6 Allen key).
 RODIACUT 130: Insert the motor from above into the fitting on the drill rig and use screws to
clamp (size 6 Allen key).
 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 (8) 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)
 Hand-guided suction ring: Select a suitable disc with hole cut-out (4 different sizes) and fix in
the device. Connect the water extraction ring (No. FF35701) to the water extractor (No.
FF35210).
