7.4. Setting the speed (Fig. 1/5/6)
First switch the machine off, then pull out the mains
plug.
The various spindle speeds can be set by moving the
V-belt.
Proceed as follows:
Remove the screw (16) in order to open the V-
b
belt cover (7).
Slacken the tightening screw (15) and push the
b
motor (8) in the direction of the machine head.
Move the V-belt to the desired position.
b
Refer to the table for the recommended speeds
b
for different drill bit materials.
Tighten the V-belt by pushing the motor (8) back
b
from the machine head (6). Screw the tightening
screw (16) back down again. The tension is
properly set when the V-belt flexes in the middle
by approx. 1 cm when pressed.
Close the V-belt cover and screw down using the
b
screw (16).
The V-belt cover (7) must always be locked tight, as
the machine is equipped with a safety switch that
only allows the machine to be turned on when the V-
belt cover (7) is closed.
Caution! Never let the pillar drill run when the V-belt
cover is open. Always pull the mains plug before
opening the cover. Never touch the V-belt when it is
rotating.
7.5. Drill depth stop point (Fig. 7)
The drilling spindle has a swiveling scale ring for
setting the drill depth. Only adjust the setting when
the machine is at a standstill.
-Lower the drilling spindle (11) until the tip of the drill
bit touches the workpiece.
-Slacken the clamping screw (17) and turn the scale
ring (25) forwards until it stops.
-Turn the scale ring (25) back to the desired drill
depth, then lock this setting into place using the
clamping screw (17).
7.6. Setting the angle of the drill table (Fig. 8)
Slacken the carriage bolt (26) under the drill
b
table (4).
Set the drill table (4) to the desired angle (which
b
can be read off the scale on the top side of the
drill table).
Tighten down the carriage bolt (26) in order to
b
lock the drill table (4) into this position.
7.7. Setting the height of the drill table (Fig. 1)
Slacken the tightening screw (5).
b
Set the drill table (4) to the desired height by
b
pressing down or lifting up and simultaneously
14
(gently) pushing to the left or right.
Screw the tightening screw (5) back down again.
b
7.8. Locking the workpiece into position (Fig. 1)
As a general rule, use a machine vice (14) 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 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.
7.9. 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.
7.10. 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.
