Instruction & User Manual
m
Press in the direction selector switch with
the arrow pointing to the chuck for rotation
to the right/screwing/drilling.
m
Press in the direction selector switch with
the arrow pointing away from the chuck for
rotation to the left/unscrewing.
Torque Setting
m
Before you start working you should test
your selection to find a suitable torque
setting on a sample of the same material as
the work piece.
m
The lowest torque is with the arrow
pointing to 1. Higher numbers mean higher
torque.
m
To use the highest torque the tool can
produce, set the mode selector to the drill
symbol. In this mode the torque inhibitor is
not activated.
m
For driving screws, especially in wood, a low
torque should be selected to reduce the
risk of damaging the screw head, thread or
work piece.
m
A high torque setting is best for drilling.
Mode Selector
Drilling Mode
Check that the drill bit is correctly inserted
and the chuck is properly tightened before
starting the power tool.
NOTE
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 power 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
Screw Driving Mode
Check that the drill bit is correctly inserted
and the chuck is properly tightened before
starting the power tool.
NOTE
m
Do not over-tighten screws.
This risks
damaging the screw head or thread.
To tighten screws:
Only use the torque setting ring when the
power tool is stopped and the chuck is not
rotating. Otherwise the power tool can be
damaged.
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 power tool, workpiece or drill bit.
