ENGLISH – ORIGINAL INSTRUCTIONS

Due to continuous product development and technical

improvements, technical information may be changed wit-

hout prior notice.

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.

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.
