INTENDED USE
Your D21580, D21582 diamond drilling machine has
been designed for dry drilling into masonry materials
such as brick, breezeblock, etc. with a dry diamond
core bit, up to 92 mm, in conjunction with a dust
extraction.
Your D21582 diamond drilling machine can also be
used for wet drilling into engineered bricks, stone
concrete and reinforced concrete with wet diamond
core bits and a water supply.
The machine can be used handheld in applications
up to 100 mm for masonry or 40 mm for concrete.
When drilling holes larger than 100 mm diameter
in masonry or 40 mm diameter in concrete, the
machine must be used on a drill stand,
e. g. D215821.
DO NOT use under wet conditions or in presence
of flammable liquids or gases.

These diamond drills are professional power tools.
DO NOT let children come into contact with the
tool. Supervision is required when inexperienced
operators use this tool.
• Young children and the infirm. This appliance
is not intended for use by young children or
infirm persons without supervision.
• This product is not intended for use by persons
(including children) suffering from diminished
physical, sensory or mental abilities; lack of
experience, knowledge or skills unless they are
supervised by a person responsible for their
safety. Children should never be left alone with
this product.
Torque Limiting Clutch
This tool is equipped with a torque limiting clutch
that reduces the maximum torque reaction
transmitted to the operator in case of jamming of
a drill bit. This feature also prevents the gearing
and electric motor from stalling. The torque limiting
clutch has been factory-set and cannot be adjusted.
Electronic Overload Protection
The electronic overload protection offers additional
safety: if the current approaches a certain limit,
the warning indicator LED (C) lights up to indicate
that the machine switches into overload mode if
operation is continued at the same pressure level.
Reduced operator pressure on the machine makes
the electronics switch back into normal mode.
If continuous overload pressure is applied, the
machine switches off. Thus, overheating of
the motor windings is avoided. The machine is
operational again after the load has been released.

Thermal Protection

After the machine has worked in overload for a
long period of time, the thermal protection shuts
off the machine to protect the motor. The machine
will be operational after the thermal protection has
cooled down. The time of cooling down depends
on the overheating of the motor and the ambient
temperature.

Water Supply

D21582
The integrated water swivel works directly through
the motor shaft to provide continuous cooling of the
core bit in wet drilling applications.
