Drilling masonry
▪ For maximum performance use carbide-tipped
masonry impact bits when drilling holes in brick,
tile, concrete etc.
▪ Turn the mode selector to hammer mode, then
rotate the torque collar to the drill position.
▪ Apply light pressure and medium speed for best
results in brick.
▪ Apply additional pressure and high speed for
hard materials such as concrete.
▪ When drilling holes in tile, practice on a scrap
piece to determine the best speed and pres-
sure.
Drilling wood
▪ For maximum performance, use high speed
steel bits for wood drilling.
▪ Ensure that the mode selector is in normal drill-
ing mode.
▪ Begin drilling at a very low speed to prevent the
bit from slipping off the starting point. Increase
the speed as the drill bites into the material.
▪ When drilling through holes, place a block of
wood behind the work piece to prevent rag-
ged or splintered edges on the back side of the
hole.
WARNING. Never attempt to lock the trigger
switch in the on position, do not lock the trigger
on jobs where your hammer drill may need to be
stopped suddenly.
All drilling operations
▪ Mark off the centre of the hole using a centre
punch or nail.
CHUCK REPLACEMENT
Chuck removal
Always wear eye protection.
Turn the torque adjustment collar/hammer selec-
tion collar (2) to the “drill” position and low gear, on
the gear selector (13). Tighten the chuck around
the shorter end of a hex key (not supplied) of 5 mm
or greater size.
Using a wooden mallet or similar object, strike
the longer end in the clockwise direction. This will
loosen the screw inside the chuck. 11

2. Insert a 5 mm hex key into front of chuck be-
tween jaws to engage screw head. Remove
screw by turning clockwise.
3. Place the hex key in chuck and tighten. Using
a wooden mallet or similar object, strike key
sharply in the anti-clockwise direction. This will
loosen the chuck so that it can be unscrewed by
hand.
Chuck installation
