OPERATING INSTRUCTIONS cont.

BEFORE OPERATING THIS TOOL
A) CHARGE THE BATTERY
The battery charger supplied is only for the Li-ion battery installed in the 

tool. Do not use another battery charger. The Li-ion battery is protected 

against deep discharging. When the battery is empty, the tool is 

switched off by means of a protective circuit: The tool will not turn on when the 

trigger is engaged. When the Battery Pack is charged for the first time or after 

prolonged storage, the Battery Pack will accept a 100% charge only after 

several charge and discharge cycles.
B) CHARGING (See Fig. 3)
Plug the charger plug into a suitable 

power outlet. Next, connect the 

charger to the Charging Socket on the 

screwdriver; the indicator will illuminate 

Red during charging. Let the battery 

charge for 3-5 hours. The battery is fully 

charged as soon as the indicator changes 

to Green. Then unplug the charger. 

Disconnect the Charger from the 

screwdriver. The screwdriver is ready to 

be used.
Important: When charging, the charger and screwdriver may become 

warm to the touch; this is normal and does not indicate a problem.
SELECTING A BIT 
Pull the Slide button back (1) completely. Manually rotate the Bit Cartridge 

counterclockwise until the desired bit appears in the top window (2). 

Push the Slide button forward (3) completely. (SEE Fig. 4 & 4A). The magnetic
