10.4 Handling the sprocket chuck (23)
Your tabletop drill is equipped with a sprocket chuck
(23). In order to insert a drill bit, first fold the chuck
guard (16) up, then insert the drill bit and tighten the
sprocket chuck (23) with the chuck key (26) supplied.
Remove the chuck key again (26).
Ensure that the clamped tools are tight.
Clamping the drill bit
Always ensure that the mains plug is removed when
changing the tool.
Only cylindrical tools with the specified maximum
shaft diameter are permitted to be clamped in the
sprocket chuck (23). Only use faultless and sharp
tools. Do not use any tools with damaged shafts or
that are deformed or damaged in any other way. Only
use accessories 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 sprock-
et chuck (23) that the chuck's jaws can grip in
an optimum 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
sufficiently so that the drill bit cannot slip when
working.
Attention! Do not leave the chuck key (26) insert-
ed.
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).
10.5 Working speeds
Ensure that the speed is correct when drilling. This
depends on the drill bit diameter and the material.
The list below helps you to choose speeds for the var-
ious materials.

Setting the speed and V-belt tension for dp16 sl
(Fig. 13 and 13.1)
m Attention!
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 col-
umn 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 correspond-
ing pulleys (38).
4. Press the right of the motor (13) backwards in
order 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.
