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 (6) up.
2. Release the retaining jaws of the drill
chuck (4) with the drill chuck key (26)
you find in the holder (10).
3. Remove the bit.
4. Insert a new bit.
5. Tighten the retaining jaws of the drill
chuck (4) with the drill chuck key (26).
6. Affix the hole chuck key (26) on the
holder again (10).
7. Check that the bit is centred.
8. Fold the safety device (6) down again.
9. Carry out a brief trial run in order to
check the drill for true running.
Under no circumstances must you lea-
ve the drill chuck key (26) inserted.
Drilling
1. Turn the appliance on.
2. Turn one of the drill lifting arms antic-
lockwise
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.
Adjusting the laser
F
Caution! - Laser beam. Do not look
into the beam. Turn your head
away or close your eyes to prevent
looking into the laser beam. Dan-
ger of eye injury!
1. Spot-drill the clamped workpiece. Do
not make any further changes to the
position of the workpiece until the laser
has been adjusted.
2. Turn the laser (34) on at the on/off
switch.
3. Set the laser cross to where the workpi-
ece has been spot-drilled by turning the
two controllers (35).
Inserting/replacing
G
laser batteries
1. Turn the laser off.
2. Open the battery compartment of the
laser (36) by sliding the lock upwards
and opening the compartment.
3. Insert the batteries according to the po-
larity indicated on the cover.
4. Close and lock the battery compartment
(36).
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.
