Handling (Ill. B-2) - Rothenberger FF40150 Bedienungsanleitung

Functional residual current shut-down test Operate the OFF/TEST button (15) – the
residual current device shuts down and the orange control lamp (13) goes out.
It must be possible to operate the connected equipment after the PRCD is switched on
again.
If the PRCD is not triggered or if it shuts down repeatedly when the electric equipment is
switched on, the entire combination must be checked by an electrician.
Further operation is not permitted before this is carried out - danger to life!
Water supply:
Water is supplied from the water tank (9) during drilling.
Set the water quantity using the valve (4), position 1 means a small amount of water and
position 2 plenty of water.
Operate the water flow to the bore crown and borehole location manually using the control
valve (5).
The water tank can be opened for filling with water by turning the cap nut (10). The pressure
necessary for the water supply is generated by the piston pump (11).

Handling (ill. B-2)

Fill the water into the pressure tank carefully.
The maximum filling quantity should not exceed 0.75 litres, see marking on the water tank
(9).
Water must not run over the equipment. Use a funnel if necessary. Only fill with clean
water (tap water).
Pumping up of the pressure tank: approx. 10 pump strokes.
Use the thumb wheel (4) to set the desired water flow. Small amount of water: position 1,
plenty of water: position 2.
Set the suitable speed using the gear change (7) rotary switch.
Hold the equipment firmly by the hand grip (12). Use the other hand to guide the neck at
the front of the equipment under the valve block.
Be sure without fail to take up a firm position. Do not stand on ladders or other
moving items.
Use the switch (8) to switch on the equipment (with "acceleration" function) and
accelerate immediately to maximum speed.
Apply the bore crown and start drilling using consistent pressure. Use of the optional
FF35750 spot drill aid is recommended at the face of the borehole.
Briefly operate the water supply valve.
Continue drilling using slight follow-up pressure and in the process consistently impulse-
press the water supply valve.
Relieve the crown at intervals and retract slightly (oscillating movement) in order to flush
out the drilling mud.
Use continuous flushing when changing over from drilling tiles or natural stone to drilling the
subjacent carrier stone in order to keep the drill as free from drilling mud as possible.
