Changing the Bit

Remove the plug from the mains
socket before changing the bit. This
will prevent an accidental start-up.
1. Fold the safety device (7) up.
2. Release the retaining jaws of the drill
chuck (4) with the drill chuck key (29).
3. Remove the bit.
4. Insert a new bit.
5. Tighten the retaining jaws of the drill
chuck (4) with the drill chuck key (29).
6. Affix the hole chuck key (29) on the
holder again (10).
7. Check that the bit is centred.
8. Fold the safety device (7) down again.
Under no circumstances must you
leave the drill chuck key (29) inser-
ted.

Drilling

1. Turn the appliance on.
2. Turn one of the drill lifting arms (9) an-
ticlockwise
3. The drill chuck (4) is lowered.
4. Drill into the workpiece at the appropri-
ate feed rate and to the desired depth.
5. Be aware of any necessary chip brea-
king on the way to the desired depth.
6. Move the bit slowly back to the stop
position.

General Information

The feed rate and spindle speed
are decisive for the service life of
the bit.
- The cutting speed is determined by the
speed of the drill spindle and by the
diameter of the bit.
- In principle, therefore, the larger the
bit diameter, the lower the speed that
should be selected.
- For workpieces of greater strength, the
cutting pressure must be higher.
- Repeated withdrawal of the bit enables
easier chip removal.
- Chip removal is especially difficult in
deep holes. Reduce the feed rate and
speed in this case.
- To avoid excessive wear on the cutting
surface of the bit, for drill holes over
8.0 mm in diameter you should first
drill with a bit with a smaller diameter.

Switching on and off

Make sure that the power supply
voltage matches the voltage rating
indicated on the device's type pla-
te.

supply.
Caution! Fold the protective
device (7) down before you
switch on the machine.
Switching on:
Press the on switch (2).
Switching off:
