7.7. Setting the angle of the drill table (Fig. 21-22)
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.
7.8. Setting the height of the drill table
(Fig. 21; 23)
Slacken the tightening screw (37).
Set the drill table to the desired position with the
help of the hand crank (27).
Screw the tightening screw (37) back down
again.
7.9 Drill table and roll base (Fig. 24)
Slacken the clamping screw (29) to turn the drill
table (4).
Slacken the thumb screws (21) to extend the roll
base (3).
7.10 Clamping the workpiece (Fig. 25)
As a general rule, use a machine vice or another
suitable clamping device to secure a workpiece in
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 workpiece cannot rotate.
This is best achieved by placing the workpiece
/machine vice on a sturdy block. Caution! Sheet
metal parts must be clamped in to prevent them from
being torn up. Properly set the height and angle of
the drill table for each workpiece. There must be
enough distance between the upper edge of the
workpiece and the tip of the drill bit.
This machine is fitted with an adjustable stop (30).
Proceed as follows to position it:
Move the sliders on the stop (30) into two of the
four guide slots in the drill table (4).
Set the stop (30) to the desired position.
Fasten the stop (30) to the drill table using both
spindle screws (32).
Now slacken the thumb screw (33) on the angle
piece (34) and position the angle piece (34) such
that the workpiece can be placed against the
stop (30) and the angle piece (34).

7.11 Using the laser (Fig. 11; 18/Item 36)
To switch on: Move the ON/OFF switch (20) to the
"I" position to switch on the laser. Two laser lines are
projected on the workpiece and intersect at the
center of the drill tip contact point.
To switch off: Move the ON/OFF switch (20) to the
"0" position.
Setting the laser: Slacken the screws (41) to adjust
the laser. Retighten the screws after you have made
the adjustment. Important! Never look directly into
the laser beam!
7.12 Working speeds
Ensure that you drill at the proper speed. Drill speed
is dependent on the diameter of the drill bit and the
material in question.
The table below acts as a guide for selecting the
proper speed for various materials.
Note: The drill speeds specified are merely
suggested values.

7.13 Countersinking and center-drilling
With this table drill, you can also countersink and
center-drill. Please observe that countersinking
should be performed at the lowest speed, while a
high speed is required for center-drilling.
7.14 Drilling wood
Please note that sawdust must be properly
evacuated when working with wood, as it can pose a
health hazard. Ensure that you wear a suitable dust
mask when performing work that generates dust.
