Do not use any tools with damaged shafts or that are
deformed or damaged in any other way. Only use ac-
cessories and additional equipment that are specified
in the operating manual or that have been approved by
the manufacturer.
1. Insert the drill bit deeply enough into the sprocket
chuck (23) that the chuck's jaws can grip in an op-
timum manner. (Ensure that the jaws do not touch
the drill bit's spirals on small drill bits).
2. Ensure that the drill bit is centred in the sprocket
chuck (23).
3. Use the chuck key (26) to tighten the chuck suffi-
ciently so that the drill bit cannot slip when work-
ing.
Attention! Do not leave the chuck key (26) inserted.
Danger of injury due to the chuck key (26) ejecting.
Changing the sprocket chuck (23)
Turn the outer ring on the sprocket chuck (23) as far as
possible in an counterclockwise direction.
Tap the sprocket chuck (23) gently with a wooden or
rubber hammer. Hold the chuck with the other hand
when it slides off the spindle (33).

(Fig. 13 and 13.1)
m Attention!
Always unplug the mains plug before opening the

complete standstill prior to performing maintenance /
setting work (danger of injury)! Never run the drill when
the V-belt cover 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 device 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.
