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 authorised D WALT 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 inthe 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.
Cutting Metal
For cutting with bonded abrasives, always use
a protection guard type 1.
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.
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 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.
WARNING: To reduce the risk
of serious personal injury, turn
tool off and disconnect tool from
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.
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
