Inserting Tool Bits
Important!
Always remove the battery before you change the drill or screw bit to
avoid unintentional starting of the tool. With keyless chuck of the cordless drill,
you do not need a key to lock the tool bit in place. Make sure that the drill or
screw bit is not askew 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 counterclockwise. 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 counterclockwise. 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 tool off,
release the operating trigger
Forward and reverse switch
Important!
The tool must 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
counterclockwise 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
adjustment knob. There are 16 (drive)+1(drill)+1(impact) position for choice.
Attention!
The torque adjustment knob should only be operated when the
tool is not running; otherwise the tool may be damaged.
To set the drill to the lowest available torque setting, twist the torque adjustment
knob until the small arrow on the drill-
housing points to the “1” stamped on the
torque adjustment knob. In this position the torque clutch will slip with light
drilling resistance. The higher the number that arrow points to on the torque
adjustment knob, the larger the maximum torque that can be applied before the
torque clutch will slip.
To set the tool to maximum available torque twist the torque adjustment knob
until the arrow points to the drill symbol. In this position, there is no slip in the
torque clutch.
