Setting the Speed/Impact Rate
The speed/impact rate of the switched on power
tool can be variably adjusted, depending on how
far the On/Off switch 8 is pressed.
Light pressure on the On/Off switch 8 results in low
speed/impact rate. Further pressure on the switch
increases the speed/impact rate.
Overload Clutch
 If the tool insert becomes caught or jammed,
the drive to the drill spindle is interrupted. Be-
cause of the forces that occur, always hold the
power tool firmly with both hands and provide
for a secure stance.
 If the power tool jams, switch the machine off
and loosen the tool insert. When switching the
machine on with the drilling tool jammed, high
reaction torques can occur.
Temperature Control Indicator
The red LED of the temperature control indicator
14 signals that the battery or the electronics of the
power tool (when the battery is inserted) are not
within the optimum temperature range. In this
case, the power tool will not operate at full capaci-
ty.
Temperature control of the battery:
– The red LED 14 lights up continuously after in-
serting the battery into the charger: The battery
is not within the charging temperature range be-
tween 0 °C and 45 °C and cannot be charged.
– The red LED 14 flashes when you press the 16
button or the On/Off switch 8 (with battery insert-
ed): The battery is outside of the permitted oper-
ating temperature range.
– For battery temperatures over 70 °C, the power
tool switches off until the battery is in the optimal
temperature range again.
Temperature control of the power tool electronics:
– The red LED 14 lights up continuously when
pressing the On/Off switch 8: The temperature
of the machine's electronics is below 5 °C or
above 75 °C.
– At a temperature above 90 °C , the electronics of
the power tool switch off until the temperature is
within the allowable temperature range again.
Working Advice
Vibration Damper
The integrated vibration damper reduces occurring
vibrations.
The soft grip handle increases the safety against
slipping off and thus provides for a better grip and
handling of the power tool.

For optimum use of the vibration-dampening fea-
ture, hold the power tool in the upper gripping ar-
ea.
Inserting Screwdriver Bits (see figure J)
 Apply the power tool to the screw/nut only
when it is switched off. Rotating tool inserts can
slip off.
To work with screwdriver bits, a universal bit holder
27 with SDS-plus shank (accessory) is required.
Clean the shank end of the adapter shank and ap-
ply a light coat of grease.
Insert the universal bit holder with a turning motion
into the tool holder until it automatically locks.
Check the locking effect by pulling the universal bit
holder.
Insert a screwdriver bit into the universal bit holder.
Use only screwdriver bits that match the screw
head.
To remove the universal bit holder, pull the locking
sleeve 4 toward the rear and remove the universal
bit holder 27 out of the tool holder.
Recommendations for Optimal Handling of the
Battery
Protect the battery against moisture and water.
Store the battery only within a temperature range
between –20 °C and 50 °C. As an example, do
not leave the battery in the car in summer.
Occasionally clean the venting slots of the battery
using a soft, clean and dry brush.
A significantly reduced working period after charg-
ing indicates that the battery is used and must be
replaced.
Observe the notes for disposal.
Maintenance and Service
Maintenance and Cleaning
 Before any work on the machine itself (e. g.
maintenance, tool change, etc.) as well as dur-
ing transport and storage, remove the battery
from the power tool. There is danger of injury
when unintentionally actuating the On/Off
switch.
