INTENDED USE
Your D21583 diamond drilling machine has been
designed for dry drilling into masonry materials such
as brick, breezeblock, etc. with a dry diamond core
bit in conjunction with a dust extractor.
Your 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 72 mm for concrete.
When drilling holes larger than 100 mm diameter
in masonry or 72 mm diameter in concrete, the
machine must be used on a drill stand.
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
The integrated water swivel works directly through
the motor shaft to provide continuous cooling of the
core bit in wet drilling applications.
Electrical Safety
The electric motor has been designed for one
voltage only. Always check that the power supply
corresponds to the voltage on the rating plate.
Your D WALT tool is double insulated in
E
accordance with EN60745; therefore no
earth wire is required.
In case of cord or plug replacement, the tool must
only be repaired by an authorized service agent or
by a qualified electrician.
Using an Extension Cable
If an extension cable is required, use an approved
3–core extension cable suitable for the power
input of this tool (see technical data).The minimum
conductor size is 1.5 mm

is 30 m.
When using a cable reel, always unwind the cable
completely.
