Repairs

WARNING: To assure product SAFETY and RELIABILITY,
repairs, maintenance and adjustment (including brush
inspection and replacement) should be performed by a
DeWALT factory service center or a DeWALT-authorized
service center. Always use identical replacementparts.
If the supply cord is damaged, it must be replaced by the
manufacturer, its service agent or similarly qualified persons
in order to avoid ahazard.
Optional Accessories

WARNING: Since accessories, other than those offered
by DeWALT, have not been tested with this product, use
of such accessories with this tool could be hazardous.
To reduce the risk of injury, only DeWALT recommended
accessories should be used with thisproduct.

WARNING: Do not use a bonded abrasive wheel that
is past its expiration (EXP) date as marked near center
of wheel (if provided). Expired wheels are more likely to
burst and cause serious injury. Store bonded abrasive
wheels in dry location without temperature or humidity
extremes. Destroy expired or damaged wheels so they
cannot beused.
Consult your dealer for further information on the
appropriateaccessories.
Cleaning

WARNING: Blow dirt and dust out of all air vents with
clean, dry air at least once a week. To minimize the
risk of eye injury, always wear approved eye protection
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 plastic 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.
Pop‑off Brushes
The motor will be automatically shut off indicating that the
carbon brushes are nearly worn out and that the tool needs
servicing. The carbon brushes are not user‑serviceable. Take
the tool to an authorised DeWALT repairagent.
Maintenance

WARNING: To reduce the risk of serious personal
injury, turn unit off and disconnect it from
power source before making any adjustments or
removing/installing attachments or accessories.
An accidental start-up can causeinjury.
Your DeWALT power tool has been designed to operate
over a long period of time with a minimum of maintenance.
Continuous satisfactory operation depends upon proper tool
care and regularcleaning.
Working Advice
Exercise caution when cutting slots in structuralwalls.
Slots in structural walls are subject to the country‑specific
regulations. These regulations are to be observed under
all circumstances. Before beginning work, consult
the responsible structural engineer, architect or the
constructionsupervisor.
Cutting Stone
The machine shall be used only for drycutting.
For cutting stone, it is best to use a diamond cutting
disc. Operate the machine only with additional dust
protectionmask.
Rough Grinding
Never use a cutting disc forroughing.
Always use the guard TypeB.
The best roughing results are achieved when setting the
machine at an angle of 30° to 40°. Move the machine
back and forth with moderate pressure. In this manner, the
workpiece will not become too hot, does not discolour and
no grooves areformed.
Cutting Metal
For cutting with bonded abrasives, always use the
TypeAguard.
When cutting, work with moderate feed, adapted to the
material being cut. Do not exert pressure onto the cutting
disc, tilt or oscillate themachine.
Do not reduce the speed of running down cutting discs by
applying sidewardpressure.
The machine must always work in an upgrinding motion.
Otherwise, the danger exists of it being pushed uncontrolled
out of thecut.
When cutting profiles and square bar, it is best to start at the
smallest crosssection.
Metal Applications
When using the tool in metal applications, make sure that
a residual current device (RCD) has been inserted to avoid
residual risks caused by metalswarf.
If the power supply is shut off by the RCD, take the tool to an
authorised DeWALT repairagent.

WARNING: In extreme working conditions, conductive
dust can accumulate inside the machine housing when
working with metal. This can result in the protective
insulation in the machine becoming degraded with a
potential risk of an electricalshock.
To avoid build‑up of metal swarf inside the machine, we
recommend to clear the ventilation slots on a daily basis.
Refer toMaintenance.
the angle will cause the wheel to bend and may cause
wheel breakage. Edge grinding wheels are not designed
to withstand side pressures caused bybending.
5. Remove the tool from the work surface before turning
the tool off. Allow the tool to stop rotating before laying
itdown.
