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.
● 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.
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.
