Setting the speed and V-belt tension (Fig. 13 and 13.1)
m WARNING
Always unplug the mains plug before opening the cover.
Always wait until the machine has come to a complete
standstill prior to performing maintenance / setting work
(danger of injury)! Never run the drill when the V-belt cov-
er is open. Never reach into the V-belt while it is running.
You can set various spindle speeds on your box column
drill:
1. Once you have switched the product off, you can
open the belt guard (14) by undoing the locking
screw (15). All adjustment options for the spindle
speed are available on the machine's belt guard (14).
2. Slacken the drive belt (36) on the right of the ma-
chine head (8) by undoing the wing screw (37).
Pull the right of the motor (13) slightly towards the
spindle (33) in order to slacken the drive belt (36)
3. Place the drive belt (36) around the corresponding
pulleys (38).
4. Press the right of the motor (13) backwards in or-
der to tension the drive belt (36) again.
5. Re-tighten the wing screw (37). The drive belt (36)
should have around 13 mm of play when you press
it together in the middle.
6. Close the belt guard (14) and tighten the locking
screw (15).
7. If the drive belt (36) slips during operation, re-ad-
just the belt tension.
ATTENTION:
The pulleys (38) on the opposite side must always be
used. If pulleys (38) at a different height are used, the
drive belt (36) will be destroyed.

NOTE: Safety switch
If you wish to set the speed, you must open the cov-
er. In order to prevent the danger of injury, the safety
switch switches the drill off automatically.
11.6 Depth stop (10) (Fig. 14)
NOTE:
When the clamping device is in the top position, the drill
bit's tip must be just slightly above the top of the workpiece.
The depth stop (10) enables the drilling depth to be
limited:
1. Set the desired drilling depth.
2. Screw it on tightly against the lower stop (12) using
the knurled nuts (11).
11.7 Positioning the workpiece (Fig. 15)
• Always place a base (A) (e.g. wood) between the
table and workpiece. This prevents the rear of the
workpiece splitting or breaking when drilling through.
• In order to prevent the base turning uncontrollably,
lean it against the left of the column (5) as illustrated.
m WARNING
If the workpiece or the base is not long enough for this,
clamp it to the table, as otherwise, serious injuries may
occur.
NOTE
Use the machine vice (accessory) for smaller work-
pieces that cannot be clamped to the table.
The vice must be clamped or screwed to the table in
order to prevent injuries due to rotating workpieces or
the vice, and to prevent destroying the tool.
11.8 Drilling a hole
1. Use a punch or a sharp nail to mark the location to
be drilled on the workpiece.
2. Before you switch the drill on, lower the drill bit
onto the workpiece and centre it over the location
to be drilled.
3. Switch the machine on and press the drill bit gently
onto the workpiece so that it can cut cleanly.
If there is insufficient downward pressure, there is the
risk that the drill bit will become hot.
If there is excessive downward pressure, there is the
risk that the motor (13) will block, the V-belt or the drill
bit will slip, the workpiece will come loose or the drill
bit will break.
