power source before making any
adjustments or removing/installing
attachments or accessories. Before
reconnecting the tool, depress and
release the trigger switch to ensure that
the tool is off.
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 D
e
WALT repairagent.
Lubrication
Your power tool requires no additionallubrication.
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.
Optional Accessories
WARNING: Since accessories, other
than those offered by D
e
WALT, have not
been tested with this product, use of
such accessories with this tool could be
hazardous. To reduce the risk of injury,
only D
e
WALT recommended accessories
should be used with thisproduct.
Consult your dealer for further information on the
appropriateaccessories.
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.
Rough Grinding
Never use a cutting disc forroughing.
Always use the guard type27.
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 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.
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.
Using Flap Discs
WARNING: Metal dust build-up.
Extensive use of flap discs in metal
applications can result in the increased
potential for electric shock. To reduce
this risk, insert an RCD before use and
clean the ventilation slots daily by blowing
dry compressed air into the ventilation
slots inaccordance with the below
maintenanceinstructions.
MAINTENANCE
Your D
e
WALT 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.
