6.9 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).
6.10 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 work-
piece. There must be enough distance between
the upper edge of the workpiece and the tip of the
drill bit.
This machine is fi tted 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).
6.11 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!
6.12 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.

6.13 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.
6.14 Drilling wood
Please note that sawdust must be properly eva-
cuated 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.
