Instruction & User Manual
m
If loose, clamp the work piece. The work
piece should lie flat on a workbench, and/or
be securely fixed.
m
Mark out the position of the hole by suitable
means.
m
Use a suitable drill bit for your material.
m
Ensure all drill bits are sharp.
m
When drilling in metal, make sure that the
drill bit is always sufficiently cooled with a
non-flammable liquid.
m
Start drilling at low speed.
m
If you are drilling large holes, pre drill with a
small drill bit and then finish off with a large
drill bit.
m
Do not force the tool - do not press too
hard on the drill bit.
The drill bit can jam in deep holes. Release
the ON/OFF Trigger immediately if the drill
bit jams. Switch to anticlockwise rotation and
run the drill bit loose at low speed.
NOTE
Hammer Drilling Mode
m
Set the selector ring in hammer mode to
connect the hammer function. The hammer
function allows more effective drilling into
hard, brittle materials such as concrete, brick
and stone.
Screw Driving Mode
Check that the bit is correctly inserted and
the chuck is properly tightened before start-
ing the power tool.
NOTE
m
Do not over-tighten screws.
This risks
damaging the screw head or thread.
To tighten screws:
m
Set the rotation selector to clockwise
rotation.
m
Place the bit into the screw head in line with
the screw. Otherwise the screw can be
damaged.
m
Press the bit firmly against the screw and
drive in the screw.
m
Once the screw is sufficiently tightened,
release the power switch
before
you stop
pressing in the screw, otherwise you can
damage the screw or screw head. The
bit or tool can be damaged if you do not
release the power switch immediately.
To unscrew/loosen screws:
m
Set the rotation selector to anticlockwise
rotation.
m
Place the bit into the screw head in line with
the screw. Otherwise the screw can be
damaged.
m
Press the bit firmly against the screw and
loosen the screw.
Gearbox Speed Selector Switch
Only use the gearbox speed selector switch
(4) when the power tool is stopped and the
chuck is not rotating. Otherwise the power
tool can be damaged.
WARNING!
m
Move the gearbox speed selector switch (4)
switch away from the chuck to position 1 for
low speed (0 to 500rpm).
m
Use the low speed mode for screw driving
and for drilling holes with a large diameter.
m
Move the gearbox speed selector switch (4)
forwards towards the chuck to position 2 for
high speed (0 to 1800 rpm).
