Long duration operation
DANGER!
Danger of accident!
If the machine should fall out of your hand during long duration operation, it
will not automatically shut off. In this situation, immediately pull out the
power plug and turn the machine off. To ensure a safe long duration
operation:
•Hold the machine securely at all times.
•Always keep one finger on the On/Off button to be able to turn it off quickly.
•If the machine falls out of your hand during long duration operation,
immediately pull out the power plug.
Setting the rotation speed
By pressing the Rotation speed setting-ring (6), you can set the rotation speed during
idle operation.
The optimal rotation speed is dependent upon the work piece, the operation mode,
and the inserted drill.
Light pressure on the Rotation speed setting-ring (6)
low rotation speed (intended for: small/short screws, soft working materials)
Greater pressure on the Rotation speed setting-ring (6)
higher rotation speed (designated for: large/long screws, hard working materials)
Tip:
To prevent the cracking of drill holes (i.e. with tiles), drill holes first with low rotation
speed and then increase it. The drill is then easier to control and will not slip.
Selecting the rotation direction
•
Do not set the switch
(5)
left/right rotation during drilling.
•
The rotation direction is always according to the switch position.
•
Switch position R: right-rotation/forward/clockwise. To drill and to screw in
screws, push the switch (5) right/left rotation to the right until the stopper.
•
Switch position L: left-rotation/backward/counter-clockwise. To loosen or pull out
screws and nuts, push the switch (5) right/left rotation to the left until the stopper.
Changeover switch (Drilling/ Impact Drilling)
Set the changeover switch
(8) only when the impact drill is at a standstill.
•
Drilling operation mode: Set the changeover switch
(8) on the DRILL position
work on wood, metal, or plastic materials.
•
Impact drilling operation mode: Set the changeover switch (8) on the Impact
Drilling position to work on concrete, stone, or brick.
