b Please refer to table 6.12 for the corresponding
speeds 6.12.
b To tighten the V-belt, press the clamping lever
(34) in the direction of the motor and re-tighten
the fixing screw (13).
b Close the V-belt cover and screw down using the
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.
6.7 Drill depth stop point SB 501/1 (Fig. 12)
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).
6.8. Setting the angle of the drill table (Fig. 7)
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.
6.9. Setting the height of the drill table (Fig. 1/4)
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.
6.10 Clamping the workpiece (Fig. 1)
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.
6.11. 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.
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.
Note: The drill speeds specified are merely
suggested values.

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.
7.0. Care and maintenance
The table drill is to a large extent maintenance-free.
Keep the device clean.
Pull out the mains plug before doing any cleaning
and maintenance work on the machine.
Do not use any harsh, abrasive cleaning solvents.
Ensure that no liquid seeps into the device.
Regrease all bare parts when the work is finished.
The drill pillar, blank parts of the column, and the drill
table especially should be regreased at regular
