INTENDED USE
This is an insulated diamond core drilling machine
for WET use in combination with diamond core dril-
ling for drilling holes in stony materials and concrete. The
drilling machine can be used manually as well as in combi-
nation with a drill platform. This machine is suited for right
as well as left handed personel.
This is a double-isolated diamond core drill machine
for DRY use in combination with diamond core drills
for drilling holes in brick/ block and masonry. The machine
may not be used for wet drilling and is not suitable for use
with diamond core drills which must be cooled by water.
POWER SUPPLY
The drill machine may only be connected to the voltage
which is stated on the type illustration and only works with
1-phase. The machine is insulated according to European
Guidelines and consequently may only be used via a trip
switch (PRCD) with an under voltage safety level of < 10
mA on an earthed electrical mains.
The drill machine may only be connected to the vol-
tage which is stated on the serial plate and only works
with 1-phase AC. The machine is double isolated accor-
ding to European Guidelines and can therefore also be
connected contact boxes without mass cable / earthing.
SAFETY INSTRUCTIONS
• Always use the extra side handle and always hold the
drill machine with both hands
• Always use the machine under supervision. Keep hands
way from rotating parts
• Double-check that the diamond drill is correctly assem-
bled
• Before use, check that all screws are fi rmly in place. Be-
cause of vibrations caused during drilling, screws can
work loose and cause damage or injury
• After use, do not touch metal parts of the drill machine
and the diamond drill; this could be hot and cause burns.
• Ensure that the drill machine does not start rotating by
accident; always disengage the switch when discon-
necting from the power source, or if there is an interrup-
tion to the power supply

Attention: Because of the high torque in the lowest gear,
we strongly advise you not to drill by hand in the lowest
gear. If the diamond drill suddenly gets stuck there is a
high risk that the user will get hurt. Use lowest gear only in
combination with a drill rig.
PRCD SWITCH
IF APPLICABLE
The machine electrical cable is equipped with a PRCD
switch which protects the operator against electrocution.
As soon as the drilling machine is plugged in, the PRCD
should be started up by pressing on the (green) -RESET-
button. If the PRCD is switched off , the -RESET- button
must be pressed again.
Note:
• The PRCD and the electrical cable should never come in
contact with water.
• Check the PRCD by pressing the -TEST button before
use.
• Never use the diamond drilling machine without a pro-
perly functioning PRCD.
• Never replace the standard plug with another type of
plug.
WORKING PROCES
If drilling is done by hand, initially the drill should never be
applied perpendicular to the material (the drill may start
'spinning'). Spinning is prevented by drilling the fi rst cen-
timeter / 0,5 inch at an angle of 30 degrees. Then the drill
can be slowly brought to the desired position.
In order to centre without problems, it is advised to use a
pilot drill. Once the pilot drill is removed, the drill can be
placed in the pre-drilled hole.
Tips
• Diamond drills which are not precisely circular cause ex-
tra burden to the bearings and the cogs.
• Switch on the machine only if the diamond drill can turn
freely.
• When changing the diamond drill, always use 2 span-
ners. Never use a hammer as this may damage the cogs.
Extra Side handle
The side handle can be loosened by hand to change its
position. After position is set , twist the handle again until
fi rm. By removing this handle, it is possible to mount the
drilling machine in a drilling rig.
Switching on/off
If the machine is provided with a switch with a fi x button,
with which the machine can be switch on/off in 2 ways:
1 - Moment switch
Switch on; push in switch
Switch off ; release switch
2 - Permanent switch
Switch on; push in switch and secure using fi x button (for
use in a drill standard)
Switch off ; release switch and release again
