DISPOSAL OF AN EXHAUSTED BATTERY PACK
To preserve natural resources, please recycle or dispose of
the battery pack properly. This battery pack contains Lithium
batteries. Consult your local waste authority for information
Li-Ion
regarding available recycling and/or disposal options. Discharge
your battery pack by operating your drill, then remove the battery
pack from the drill housing and cover the battery pack connections
with heavy-duty adhesive tape to prevent short circuit and energy
discharge. Do not attempt to open or remove any of the components.
12
OVERLOAD PROTECTION
When overloaded, the motor comes to a stop. Relieve the load on the
machine immediately and allow cooling for approx. 30 seconds at the
highest no-load speed.
13
TEMPERATURE DEPENDENT OVERLOAD PROTECTION
When using as intended for the power tool cannot be 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.
14
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.

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 15 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.

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
10
o C as this will affect performance.
