Important! Only use the provided battery charger for charging the battery. First place the
rechargeable battery into the charging slot in the charger and then connect the charger to the
mains. Charging starts automatically.
Remove the battery from the charge after about 5 hours. Always disconnect the charger from the
mains before you remove the battery from the charger.
Inserting Tool Bits
Important! Always remove the battery before you change the drill or screw bit to avoid
unintentional starting of the machine.
The cordless drill has a keyless chuck so you do not need a key to lock the tool bit in place. Make
sure that the drill or screw bit is not skew when it is inserted and the chuck tightened.
Before inserting drill/screw bits open the jaws of the chuck by holding the lower ring of the chuck
and turn the locking ring anticlockwise. Open the chuck until you can insert the tool. Insert the
drill/screw bit all the way in and then holding the lower ring, turn the locking ring in a clockwise
direction to firmly tighten it.
To remove the tool hold the lower ring of the chuck and turn the locking ring anticlockwise.
Open the chuck until you can remove the tool
Operating Trigger
Use the operating trigger to start the machine and keep holding it for continuous operation.
The rotation speed can be varied by depressing the operating trigger. The more the trigger is
depressed, the faster rotation speed.
To switch the machine off, release the operating trigger
Forward and reverse switch
Important! The machine has to come to a complete stop before the reverse rotation lever can be
used; otherwise the machine may be damaged.
Use the forward and reverse switch to switch between clockwise (normal) and anticlockwise
rotation or vice-versa. With the forward and reverse switch in the central position the operating
trigger is locked and cannot be depressed. Put the forward and reverse switch in the central
position before you put the machine down, to avoid unintentional starting.
Torque adjustment
You can control the maximum torque applied to the drill bit with the torque control knob.
Attention! The torque control knob should only be operated when the machine is not running;
otherwise the machine may be damaged.
To set the drill to the lowest available torque setting, twist the torque control knob until the small
arrow on the drill-housing points to the “1” stamped on the torque control knob. In this position the
torque clutch will slip with light drilling resistance. The higher the number the arrow points to on the
torque control knob, the larger the maximum torque that can be applied before the torque clutch
will slip.
To set the machine to maximum available torque twist the torque control knob until the arrow
points to the drill symbol. In this position there is no slip in the torque clutch.
Select a lower torque for insertion/removal of screws to avoid damage to the work-piece (in
