Erbauer ERI717DDR, Original Instructions Manual

12. 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.

13. 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 variable clutch, 

you can find the variable clutch between the chuck 

and the drill body. Position 1 is the lowest torque 

(screw driving force) and position 18 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. I CANNOT FIT THE BATTERY INTO THE 

BATTERY CHARGER. WHY?

a) Check if the charger and the battery pack are 

specifically designed for working together. 

b) The battery can be inserted into the charger only 

in one direction. Turn the battery around until it can 

be inserted into the slot, the indicator light should 

be red when the battery is charging.

4. REASONS FOR DIFFERENT BATTERY PACK 

WORKING TIMES

Charging time issues, as above, and having
