SAFETY INSTRUCTIONS
• Only switch gears when the motor is in a complete stand-
still
• Plug in the machine only when it is switched off
• Prevent water with electricity through leaking, or dripping
from the hose
• A water collecting device must be used when drilling
overhead.
• Remove water safely using a water pump
• Always use the machine under supervision. Keep hands
away from rotating parts
• Double-check that the diamond drill is correctly assem-
bled and parallel with the drill rig.
• Before use, check that all screws of the drill motor and
drill rig are fi rmly in place. Because of vibrations cau-
sed 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.

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 only be used in combination with a
drill platform.
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.

ENGLISH – ORIGINAL INSTRUCTIONS
PRCD SWITCH
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
The drilling machine is equipped with a water tap, which
includes a 'Gardena' connection. Make sure that the core
drill is suffi ciently cooled and that the slurry is properly
discharged. The maximum permitted water pressure is 3
bars. Always use clean water to enlarge the life span of
the internal water seals. In case of leakage, the drilling
machine has to be checked IMMEDIATELY by a certifi ed
mechanical expert.
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.
Overload protection
To protect the motor, operator and diamond drill, the ma-
chine is provided with a mechanical, electronic and ther-
mal overload safety system. Whenever the engine is swit-
ched off due to overload, it must be switched on again as
soon as possible to cool the engine. Then let the drill turn
for a minimum of 1 minute.
1 - Electronic / Thermal
The LED indicates the load on the motor:
Continuously green Normal load
Blinking red Overload
Continuously red Overload; the motor will switch off
automatically
2 - Mechanical
If the drill bit suddenly gets stuck, the slip coupling is acti-
vated to disconnect the main axis from the engine. Make
sure you switch off the engine immediately and remove the
drill from the hole. When the slip coupling is activated for
a longer periods, the mechanical slip must be re-tuned by
a recognised expert.
