the bit until the value you calculated is indica-
ted on the scale.
Turn down the lower setting screw as far as it
will go.
Secure the setting by turning the upper set-
ting screw against the lower setting screw.
Danger! When setting the drill depth of a cylindri-
cal hole you must add the length of the drill tip.
6.5 Setting the angle of the drill table (Fig. 5)
Slacken the carriage bolt (26) under the drill
table (4).
Set the drill table (4) to the desired angle.
Tighten down the carriage bolt (26) in order to
lock the drill table (4) into this position.
6.6 Setting the height of the drill table (Fig. 1)
Slacken the tightening screw (5).
Set the drill table (4) to the desired height by
pressing down or lifting up and simultaneous-
ly (gently) pushing to the left or right.
Screw the tightening screw (5) back down
again.

6.7 Clamping the workpiece

As a general rule, use a machine vice or another
suitable clamping device to lock a workpiece into
position. Never hold the workpiece in place
with your hand! When drilling, the workpiece
should be able to travel on the drill table (4) for
self-centering purposes. Ensure that the workpie-
ce cannot rotate. This is best achieved by placing
the workpiece/machine vice on a sturdy block.
Danger! Sheetmetal parts must be clamped in to
prevent them from being torn up. Properly set the
height and angle of the drill table for each workpi-
ece. There must be enough distance between the
upper edge of the workpiece and tip of the drill bit.
6.8 Working speeds
Ensure that you drill at the proper speed. Drill
speed is dependent on the diameter of the drill bit
and the material it is made from.
The table below acts as a guide for selecting
the proper speed for drill bits made from various
materials.

6.9 Countersinking and center-drilling
With this drill you can also perform countersin-
king and center-drilling jobs. Please observe that
countersinking should be performed at the lowest
speed, while a high speed is required for center-
drilling.
6.10 Woodworking
Please note that sawdust must be properly eva-
cuated when working with wood, as it can be a
health hazard. Ensure that you wear a suitable
dust mask when performing work that generates
dust.

7. Replacing the power cable

If the power cable for this equipment is damaged,
it must be replaced by the manufacturer or its
after-sales service or similarly trained personnel
to avoid danger.
8. Cleaning, maintenance and
ordering of spare parts
