that the tool is correctly seated.
6.5 Setting the speed (Fig. 1/2/9/10)
First switch the equipment off , then pull the power
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-belt cover (7).
•
Slacken the securing screw (15) and push
the motor (8) in the direction of the machine
head.
•
Move the V-belt (36) to the desired position.
•
Please refer to table 6.10 for the correspon-
ding speeds.
•
To tighten the V-belt, press the clamping
lever (32) in the direction of the motor and re-
tighten the fixing screw (13).
•
Close the V-belt cover and screw down using
the screw (16).
The V-belt cover (7) must always be locked tight,
as the equipment is equipped with a safety switch
that only allows the equipment to be turned when
the V-belt cover (7) is closed.
Caution! Never let the pillar drill run when the V-
belt cover is open. Always pull power plug before
opening the cover. Never touch the V-belt when it
is rotating.
6.6. 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 equipment is at a standstill.
•
Press the drilling spindle (11) downwards 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).
6.7. Setting the angle of the drill table (Fig. 6)
•
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.
GB
6.8. Setting the height of the drill table (Fig.
1/13)
•
Slacken the tightening screw (35).
•
Set the drill table to the desired position with
the help of the hand crank (27).
•
Screw the tightening screw (35) back down
again.

6.9 Clamping the workpiece

As a general rule, use a machine vice (14) or ano-
ther 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.
Caution! 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.
6.10 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 specifi ed are merely
suggested values.
