7. 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.
8. 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 IMPACT DRIVER 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 impact driver will start to rotate.
2. 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.
