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 o󰀨 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

Whenever the engine is heavily overloaded , the overload

indication (LED) on top of the handle will start ashing. The

pressure on the diamond drill bit must than be reduced.

When the motor is overloaded too long, the LED ashes

continuously and the machine will switch o󰀨 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 o󰀨 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.

Drilling with water cooling - Water connection

IF APPLICABLE

The drilling machine is equipped with a water tap, which

includes a ‘Gardena’ connection. Make sure that the core

drill is su󰀩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 certied

mechanical expert.

Dry drilling - Dust Extraction

IF APPLICABLE

For dry drilling only use designated drill bits. Dry drilling is

only possible in masonry, brick/block and sandstone.

Dust released during dry drilling is dangerous to your he-

alth. Therefore a dust extraction system specially intended

for this purpose must be used, and if necessary, a dust

mask worn. The use of a dust extraction system is also

required to optimize the life time of the diamond drill bit. To

prevent clogging of the dust extraction system it is essenti-

al that the materials which are being drilled are completely

dry. Information about dust extraction systems is available

at your diamond tools supplier.

Dustec ® dust extraction

The A-1810DT is equipped with an integrated Dustec ®

dust extraction system which is only suitable for Dustec ®

drill bits (with dust holes in the top ange) of max. Ø82 mm

and M16 (F) connection.

The drill bit can be mounted directly on the output shaft. To

remove the drill bit xate the output shaft with a spanner

24. Then loosen the drill bit with a spanner 24, through the

hose connection of the dust extraction.

The dust released during drilling is dangerous to your he-

alth. The A-1810DT is therefore only to be used in combi-

nation with a suitable vacuum cleaner, which is connected

to the hose connection on the Dustec® system.

NASTROC ® system

The A-1821 is equipped with the robust NASTROC ® sy-

stem and the diamond drill can be changed without using

other tools. The lock nut has to loosened, so that the dia-

mond drill with NASTROC ® connection can be assem-

bled.
