the specifications page and do not exceed the length of the core bits beyond the maximum allowed by
the drill stand.
WARNING: Incorrect clamping and positioning of the drill core bit may lead to dangerous situations
by broken and ejected parts of the drill core bit. Core bits must be assembled correctly. Follow the
instructions below under "Fastening the Core Bit"
WARNING: It is necessary to always wear suitable personal protective equipment, including:
• Hearing protection, to reduce the risk of induced hearing loss,
• Gloves, when handling core bits or rough materials, to reduce injuries by sharp edges,
• Safety glasses, to prevent injuries by flying particles,
• Non-slipping footwear, to prevent injuries caused by slippery surfaces;
WARNING: A wrongly assembled machine may cause a hazardous situation. Follow the instructions
provided with the drill stand on how to fix the machine into the stand and fixing to the material to be
drilled; See also the instructions below under "Mounting to a Drilling Stand"
INTRODUCTION
This machine is for the intended purpose of diamond core drilling of concrete, masonry, stone and similar
materials. It must always be mounted on a drilling stand to operate. This machine is for professional use only,
and only trained personnel may operate this machine. All other uses which are not for the intended purpose
are prohibited.
It is equipped with a water feed system which is required for the diamond core drilling process. This water also
serves to cool the motor.
The high frequency motor with integrated power converter runs on single phase supply and features a built-in
RCD interrupter (residual current device). The rotation speed is electronically adjustable to suit various core bit
diameters. The motor has electronics for soft start, overload protection and thermal (overheating) protection.
There is an overload warning to alert the operator of load and overload conditions. Its gearbox is equipped
with a mechanical safety clutch.
Additional features include spindle threading function to more easily install the bit, and rebar assist function to
improve performance when embedded steel is encountered.
ELECTRICAL CONNECTION
The network voltage must conform to the voltage indicated on the tool name plate.
Under no circumstances should the tool be used when the power supply cable is damaged. A damaged
cable must be replaced immediately by an authorized Customer Service Center. Do not try to repair the
damaged cable yourself. The use of damaged power cables can lead to an electric shock.
