Torque Setting
WARNING!
Only use the torque setting ring when the
tool is stopped and the chuck is not rotating.
Otherwise the tool can be damaged.
Before you start working you should test
m
your selection to find a suitable torque
setting on a sample of the same material as
the work piece.
The lowest torque is with the arrow
m
pointing to 1. Higher numbers mean higher
torque.
To use the highest torque the tool can
m
produce, set the mode selector to the drill
symbol. In this mode the torque inhibitor is
not activated.
For driving screws, especially in wood, a low
m
torque should be selected to reduce the
risk of damaging the screw head, thread or
work piece.
A high torque setting is best for drilling.

WARNING!
Use the correct specification of drill bit for
the material and power tool you are working
with. Incorrect selection may cause damage
to the tool, workpiece or bit.
NOTE
Check that the drill is correctly inserted
and the chuck is properly tightened before
starting the tool.

Instruction & User Manual
If loose, clamp the work piece. The work
m
piece should lie flat on a workbench, and/or
be securely fixed.
Mark out the position of the hole by suitable
m
means.
Use a suitable drill for your material.
m
Ensure all drills are sharp.
m
When drilling in metal, make sure that the
m
drill is always sufficiently cooled with a non-
flammable liquid.
Start drilling at low speed.
m
If you are drilling large holes, pre drill with a
m
small drill and then finish off with a large drill.
Do not force the tool - do not press too
m
hard on the drill.
NOTE
The drill can jam in deep holes. Release the
power switch immediately if the drill jams.
Switch to anticlockwise rotation and run the
drill loose at low speed.
Hammer Drilling Mode
Set the selector ring in hammer mode to
m
connect the hammer function. The hammer
function allows more effective drilling into
hard, brittle materials such as concrete, brick
and stone.
Screw Driving Mode
NOTE
Check that the drill is correctly inserted
and the chuck is properly tightened before
starting the tool.
Do not over-tighten screws. This risks
m
damaging the screw head or thread.
