Handling
Changing the side of the hand wheel:
Make sure the feed gear cannot be operated unintentionally. Use the locking button (1)
to secure the feed unit.
Withdraw the black cap nut and remove the hand adapter (11).
Insert on the desired side and re-secure using the cap nut.
Setting the drill angle:
Loosen the toggle (7) and set the guide column (3) at the desired angle (75° - 60° - 45°).
Re-tighten the toggle (7).
Applying the diamond drill:
Make sure the feed gear cannot be operated unintentionally. Use the locking button (1)
to secure the feed unit.
RODIACUT 150: Insert the motor into the receptacle (2) of the drill rig from the top and fas-
ten by means of the screw.
RODIACUT 250: Slide the motor from the top as far as it will go (stop 15) into the feed unit
(10) of the drill rig and tighten using both star handles (14).
Proceed in the reverse order in order to remove.
Setting the depth control stop:
Release the screw at the depth control stop (4) and set the desired drill depth.
Re-tighten the screw firmly.
Water extraction device (accessory picture B-4):
RODIACUT 150: Unscrew both front ring bolts (5). Turn the knurled screws on the water ex-
traction device into the ring bolts and re-insert in the base plate.
RODIACUT 250: Turn both screws with knurled screws on the water extraction device into
the boreholes (19) in the base plate intended for this purpose.
Fasten the water extraction device over the ring bolts (5) by means of the spring lock or lock
the screws in place and fasten by means of the knurled screws.
Connect the water extractor and attach the suction hose to the connecting piece of the water
extraction ring.
Create a water intake.
–
hose feed directly at water supply or
–
immersion pump with bucket
PLEASE NOTE: Adequate water supply for cooling the drill bit must always be
ensured, as otherwise the drill bits can overheat very quickly and segments can come
away.
Information: We strongly advise against the use of "water pressure reservoirs" as from
a drill diameter of 200 mm, as adequate control of the water supply is very restricted in
this case.
Cut a hole in the rubber sheet appropriate to the drill bit diameter (air gap between the cut-
out rubber seal and drill bit approx. 2 – 3 mm).
Place the rubber sheet on the water extraction ring.
Drilling:
Please read and be sure to understand the drill motor instruction manual!
Turn on the water tap or switch on the water extractor.
(There must at least be sufficient water pressure to move the arising drilling mud from the
borehole)
Release the locking device (1) on the feed gear and use the hand wheel (11) to turn the drill
downward to the desired drill depth.
