subject to overload. When the load is too high or the
allowable battery temperature of 75°C is exceeded, the
electronic control switches off the power tool until the
temperature is in the optimum temperature range again.
12. PROTECTION AGAINST DEEP DISCHARGING
The Li-ion battery is protected against deep discharging
by the “Discharging Protection System”. When the
battery is empty, the machine is switched off by means
of a protective circuit: The inserted tool no longer
rotates.
PROBLEM SOLUTION
1. WHY DOES THE DRILL NOT TURN ON WHEN YOU
PRESS THE SWITCH?
The forward/reverse rotation control, which is on top of
the trigger, is positioned in the lock function. Unlock the
forward/reverse rotation control by putting it into the
required rotation position. Push the trigger and the drill
will start to rotate.
2. THE DRILL STOPS BEFORE THE SCREW IS
COMPLETELY TIGHTENED. WHY?
Verify the torque position of the torque adjusting ring,
you can find the torque-adjusting ring between the
chuck and the drill body. Position 1 is the lowest torque
(screw driving force) and position 21 is the highest
torque (screw driving force). Position is for drill
operation. Regulate the torque adjusting ring to a higher
position to reach the best result.
3. REASONS FOR DIFFERENT BATTERY PACK
WORKING TIMES
Charging time problems, as above, and having not used
a battery pack for a prolonged time will reduce the
battery pack working time. This can be corrected after
several charge and discharge operations by charging &
working with your drill. Heavy working conditions such
as large screws into hard wood will use up the battery
pack energy faster than lighter working conditions. Do
not re-charge your battery pack below 0
o
C and above
45
o
C as this will affect performance.
MAINTENANCE
Remove the battery pack from the tool before
carrying out any adjustment, servicing or
maintenance.
Your tool requires no additional lubrication or
maintenance.
There are no user serviceable parts in your power
tool. Never use water or chemical cleaners to clean
your power tool. Wipe clean with a dry cloth. Always
store your power tool in a dry place. Keep the motor
ventilation slots clean. Keep all working controls free
of dust. Occasionally you may see sparks through the
ventilation slots. This is normal and will not damage your
power tool.

tool and battery is 0
