6.9 Working speeds
Ensure that you drill at the proper speed. Drill
speed is dependent on the diameter of the drill bit
and its material.
The table below acts as a guide for selecting the
proper speed for drill bits made of various mate-
rials.
The rotational speeds shown are merely sugges-
ted values.

6.10 Countersinking and center-drilling
With this bench drill you can also perform coun-
tersinking and center-drilling jobs. Please note:
Countersinking should be performed at the lowest
speed, while a high speed is required for center-
drilling.
6.11 Woodworking
Wood dust can be a health hazard! Be sure to use
a suitable dust extractor when working with wood.
It is imperative to wear a suitable dust mask when
performing any work that generates dust.
6.12 Replacing the V-belt (Fig. 12/14-16)
The V-belt of the pillar drill can be replaced if it
becomes worn. Proceed as described in section
6.4 Speed settings.
In this case replace the V-belt (26) instead of re-
positioning it.
7. Replacing the power cable
Danger!
If the power cable for this equipment is damaged,
it must be replaced by the manufacturer or its
after-sales service or similarly trained personnel
to avoid danger.
8. Cleaning, maintenance and
ordering of spare parts
Danger!
Always pull out the mains power plug before star-
ting any cleaning work.
8.1 Cleaning
•
The pillar drill is maintenance-free to a large
extent. Keep the equipment clean. Pull out
the power plug before doing any cleaning and
maintenance work on the equipment. Do not
use any harsh, abrasive solvents for cleaning
purposes. Make sure that no liquid gets into
the equipment. Re-grease all bare parts when
the work is finished. Particularly the drill pillar,
blank parts of the column, and the drill table
should be re-greased at regular intervals. Use
a standard, acid-free lubricating grease for
this purpose.
Note: Do not dispose of oil-soaked rags,
grease-soaked rags, oil residues and grease
residues in your household rubbish. Dispose
of such materials in an environment-friendly
way. Check and clean the ventilation holes
regularly. Store the equipment in a dry room.
If the equipment becomes damaged, do not
try to repair it yourself. Leave such repairs to a
qualifi ed electrician.
•
We recommend that you clean the device
immediately each time you have finished
using it.
•
Clean the equipment regularly with a moist
cloth and some soft soap. Do not use
cleaning agents or solvents; these could at-
tack the plastic parts of the equipment. Ensu-
re that no water can seep into the device. The
ingress of water into an electric tool increases
the risk of an electric shock.
