• Whenever any of the problems mentioned
above appear, immediately cease using the
machine and have it repaired by an expert.
Electrical safety
Always check that the mains voltage is
the same as on the type plate of the
machine.
The machine is double insulated; there-
fore, no earth connection is required.
Replacement of power cords or plugs
Immediately dispose of old cords and plugs once
they have been replaced. It is dangerous to plug
a loose power cord into a mains power socket.
Use of extension leads
Only ever use approved extension leads that are
suitable for the power rating of the machine. The
minimum core thickness is 1.5 mm
2
. Whenever
using a reel extension lead, always fully unroll
the lead.
3. OPERATING
Hammer drills require very little operator
pressure. Excessive pressure on the tool
can lead to unnecessary overheating of
the motor, and burning of the driven tool.
Auxiliary handgrip
The auxiliary handgrip can be rotated 360º
around the drill head, enabling safe and comforta-
ble operation, for both left and right-handed users.
• Loosen the handgrip by turning it anticlockwise.
• Rotate the handgrip to the desire position.
• Retighten the handgrip in the new position.
Exchanging and removing drill bits
Fig. A + B
Before exchanging bits, first remove the
power plug from the wall socket.
Inspect bits regularly during use. Blunt
bits should be re-sharpened or repla-
ced.
• Lightly lubricate the shaft of the drill bit before
inserting into the machine.
• Place the shaft of the drill bit into the opening of
the drill chuck and twist until latched.
• To release and remove the drill bit pull back the
collar of drill chuck .
Setting depth gauge
• Loosen the handgrip by turning it anticlockwise.
• Insert the depth gauge ruler through the hole in
the auxiliary handgrip.
• Slide the ruler to the desired depth.
• Retighten the screw firmly.

Installing dust catcher
Fig.C
The dust catcher prevents large amounts of dril-
ling dust entering the machine when drilling into
ceilings.
• Remove the drill bit.
• Slide the dust catcher over the shaft of the drill
bit.
• Place the drill bit with catcher in the drill chuck.
• Always replace a damaged dust catcher imme-
diately.

nected to power whenever maintenance
work on the mechanical parts is taking
place.
The machines are designed to function problem-
free for a long period with a minimum of mainte-
nance. Through regular cleaning and correct tre-
atment, you help assure a long working life for
your machine.
