To prevent all danger, the machine must only be
held using the two handles (6/8). Otherwise there
may be a risk of suffering an electric shock if you drill
into cables.
6.1 Switching on and off (Fig. 1)
To switch on:
Press the control switch (4).
To switch off:
Release the control switch (4).
6.2 Hammer stop facility (Fig. 7)
The hammer drill has a hammer stop facility for
gentle initial drilling.
n Turn the rotary switch for the hammer stop
facility (5) to position (B) to switch off the
hammer facility.
n To switch on the hammer facility again the rotary
switch for the hammer stop facility (5) must be
turned back to position (A).
6.3 Rotation stop facility (Fig. 8 / 9)
The rotation function of the hammer drill can be
switched off for chiseling jobs.
n To do this, press the button (C) on the rotary
switch (3) whilst at the same time turning the
rotary switch (3) into position A (see Fig. 8).
n To switch on the rotation facility again, press
button (C) on the rotary switch (3) whilst at the
same time turning the rotary switch (3) into
position B (see Fig. 9).
Important.
Please note that it is not possible to operate the
hammer drill with the hammer stop and rotation stop
facilities both active at the same time.
Important.
Only low pressure is required for hammer drilling.
Excessive pressure will exert an unnecessary force
on the motor. Check the drill bits at regular intervals.
Sharpen or replace blunt drill bits.
