MAINTENANCE
Your D
WALT power tool has been designed to
E
operate over a long period of time with a minimum
of maintenance. Continuous satisfactory operation
depends upon proper tool care and regular cleaning.

An accidental start-up can cause injury.
Regularly take the tool to an authorized repair
agent for inspection. This includes checking the
carbon brushes, topping up oil in the gearcase and
replacement of the gearcase sealing ring.
Troubleshooting
If your tool seems not to operate properly, follow
the instructions below. If this does not solve the
problem, please contact your repair agent.
Core bit does not cut
Material too hard for core bit
• Choose a more appropriate core bit
(with softer segments).
• Apply wet drilling when appropriate.
Segments look glazed and polished
• Drill in abrasive material to re-expose diamond
segments.
Evacuated water too clear and too fluid
Water flow slows down the cutting action and
prevents the diamond segments to self-sharpen.
• Reduce water flow.
Dust accumulating in core bit
Accumulating dust slows down the drilling speed.
• Use the appropriate dust extraction device.
• Disengage drill bit regularly to evacuate cuttings.
Rotating speed not appropriate
• Refer to the technical data for proper speed
ratings.
Segments and core are burnt
• Increase water flow.
Segments wear too fast
• Choose a more appropriate core bit
(with harder segments).
• Reduce the pressure applied on the core bit.
Lubrication
Your power tool requires no additional lubrication.
Dust Extraction (Dry Operation)
WARNING: When performing a
dry cutting operation, connect a
dust extraction device designed in
accordance with the relevant regulations
regarding dust emissions.
Cleaning
WARNING: Blow dirt and dust out of
the main housing with dry air as often as
dirt is seen collecting in and around the
air vents. Wear approved eye protection
and approved dust mask when
performing this procedure.
WARNING: Never use solvents or
other harsh chemicals for cleaning the
non-metallic parts of the tool. These
chemicals may weaken the materials
used in these parts. Use a cloth
dampened only with water and mild
soap. Never let any liquid get inside the
tool; never immerse any part of the tool
into a liquid.
