order to remove screws
Switching the machine on and off
Fig. G
The on/off switch (11) is used for activating the
machine and adjusting rotation speed.
• Pressing the on/off switch (11) will activate
the machine, the further the switch is being
pushed, the faster the drill will turn.
• Releasing the on/off switch (11) will stop the
machine.
• Move the direction reversing switch (10) to the
middle position to lock the movement of the
on/off switch. It cannot be activated in this
position.
Only lay down the machine when it has
stopped running completely. Do not
place it on a dusty surface as particles of
dust could get into the mechanism.
Adjusting the torque
Fig. G
The machine has 23 different torque settings
and a special drill mode to set the power being
transmitted to the chuck.
By rotating the torque adjustment ring (12),
screws can be driven to a predetermined depth,
which is ideal for repetitive work. The higher the
number, the more torque will be transmitted.
• Select a low setting for small screws or soft
work material.
• Select a high setting for large screws, hard
work materials and when removing screws.
• You should preferably choose a setting as
low as possible when driving screws. Select
a higher setting if the motor slips before the
screw is fully tightened.
• For drilling, turn the torque adjustment ring
(12) to the setting for drilling by fully turning it
counterclockwise.
Ensure that the direction switch (10) is
always set to

during drilling.
The machine is equipped with electronic
overload protection function. When the
machine gets overloaded it will shut
down automatically. When this happens,
please wait for at least 5 seconds to let
the overload protection reset itself.
Work light (13)
Fig. A
The machine is equipped with a work light to
illuminate the work location.
• It automatically switches on when the on/off
switch is being pressed.
• It automatically switches off when the on/off
switch is released again.
Belt hook (14)
Fig. A
The machine is equipped with a belt hook for
hanging the machine to your belt during use.
Always switch the direction switch (10) to
middle position to avoid accidental
startup of the machine.
• When delivered, the belt hook (14) is
assembled to the left side of the machine.
• It can easily be removed by removing the
screw on the hook and taking it off.
• It can be assembled on the right side of the
machine when this is preferred.
User tips
When driving screws into wood, metal and other
materials:
• Before using the appliance check if the drill or
screw bit is properly fitted and centered inside
the drill chuck.
• Screw bits are available in several shapes and
dimensions. When unsure, always try if the bit
fits on the screw head without any free play
before using the machine.
• Make sure the machine is not running when
it contacts the screw. A rotating bit may slip.
This could result in damage to the work piece.
When drilling into wood, metal and other
materials:
• With small diameter drills use a high drill
speed. For large diameter drills use a low drill
speed.
• For hard materials, select a low drill speed, for
soft materials select a high drill speed.
• Fix the work piece properly, preferably by
using a clamp or vice.
• During drilling draw back the drill out of the
