Operating
1. Hold the inner ring of the chuck (3) and open the chuck by turning the
outer ring counter clockwise until you can insert the tool.
2. Insert the drill/screw bit all the way in.
3. Turn the outer ring of the chuck clockwise hand tight. This will
automatically lock the drill chuck.
Adjusting the Torque
1. With the torque setting ring (2) you can set up the maximum torque. Turn
the torque setting ring clockwise (seen from the front) to setup a higher
torque.
2. When starting to work, set the torque to a low value. When the set torque
is reached, the clutch is released and the work piece can not be damaged.
3. When the torque setting ring is set to the drill symbol, the clutch is locked
and can not slip.
Drilling
At the start of drilling select a lower speed to avoid the drill bit slipping
away from the desired hole location.
If the drill-hole is deep, the drill-bit may become jammed in the hole. In this
case a high torque could damage the drill bit or the drill. If the bit becomes
jammed, hold the machine firmly and immediately release the ON/OFF
trigger. Switch to counter clockwise rotation and use a low rotation speed
to remove the jammed drill bit more easily.
Screwing
Before using the machine check whether the screw bit is inserted
correctly. Avoid over-tightening, otherwise the screw head may be
damaged or stripping of the threads may occur.
Use the rotating direction button (11) to set up the rotion in clockwise
direction. Insert the screw-bit into the slot in the head of the screw. Hold
the screw bit right to the head of the screw, otherwise the screw or the
screw head may be damaged. Press the screw bit against the screw with a
constant pressure while driving in the screw.
To unscrew, set the rotating direction counter clockwise. Insert the screw
bit into the slot in the head of the screw. Hold the screw-bit right to the
head of the screw, otherwise the screw or the screw head may be
damaged. Press the screw bit against the screw with a constant pressure
while removing the screw.
