7. Once the desired depth is shown in the display
(30), tighten the knob (31) of the drilling depth
stop firmly.
8. The depth stop is now locked at the desired
drilling depth.
Drilling
Risk of damage! Allow the pillar drill to cool
down to room temperature after using it for
15 minutes before working further.
The drill can become jammed in the workpiece
when it is being removed from the workpiece,
which may cause kickback. Therefore, make
sure to slow down the feed motion towards
the end of the drilling procedure.
Always stand in front of the power tool. This
will ensure you always have a good view of
the drilling point. Keep hands and fingers
away from the rotating application tool. Do
not reach one arm across the other when in
front of the drive unit.
1. Prepare the pillar drill and the workpiece as
described in the preceding chapters.
2. Make sure that the protective guard (7) is lowe-
red down. An example of a properly positioned
guard is shown on figure A.
3. Align the workpiece and clamp it (see chapter
"Clamping the workpiece").
4. Connect the pillar drill to the power supply.
5. Switch on the pillar drill (see chapter "Switching
on / off").
6. For drilling, move the drill depth handle (4) with
uniform feed, until the desired drilling depth
is reached. Note: when drilling metals, briefly
interrupt the feed to break the chips.
7. After reaching the drilling depth, move the drill
depth handle (4) back to its initial position.
8. Switch the pillar drill off.
Optimum use
• The drill feed, movement of the drill bit, is done
manually using the drill depth handle (4)
• The cutting rate is influenced by the drilling
speed and the bit diameter.
• The service life of drill bits is largely determined
by the feed speed and the spindle speed. As
a general rule: Select a lower speed for large
diameter drill bits.

• For metal workpieces, reduce the feed rate and
cutting speed and cool the drill bit using drilling
oil. Metal workpieces should be centre-punched
before drilling into them.
• For larger holes in thin sheets, use a low feed
rate and cutting pressure so that the drill bit
does not get "stuck" and the bore is dimensio-
nally accurate.
• Effective chip ejection is hindered and the drill
bit becomes warmer when drilling deep holes
(deeper than 2 times the drill bit diameter).
Reduce the feed rate and drilling speed and re-
tract the bit from the hole repeatedly to improve
chip ejection.
• When drilling holes over 8 mm in diameter
pre-drilling is advisable to prevent premature
wear and stress on the drill tip.
Transport
When transporting the pillar drill tool, hold it with
both hands on the baseplate (5) or with one hand
on the main drill housing (1). Do not carry the
power tool by the drill depth handle (4).
5. MAINTENANCE
Before cleaning and maintenance, always
switch off the machine and unplug the
power cord.
Clean the machine casings regularly with a soft
cloth, preferably after each use. Make sure that the
ventilation openings are free of dust and dirt. Re-
move very persistent dirt using a soft cloth moiste-
ned with soapsuds. Do not use any solvents such
as gasoline, alcohol, ammonia, etc. Chemicals such
as these will damage the synthetic components.
ENVIRONMENT
Faulty and/or discarded electrical or
electronic apparatus have to be collected at
the appropriate recycling locations.
Only for EC countries
Do not dispose of power tools into domestic waste.
According to the European Guideline 2012/19/EU
for Waste Electrical and Electronic Equipment and its
implementation into national right, power tools that
are no longer usable must be collected separately
and disposed of in an environmentally friendly way.
