18V COMBI DRILL ERI603COM
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.
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.
