Wheels
SURFACE GRINDING WITH GRINDING WHEELS
1. Allow the tool to reach full speed before
touching the tool to the work surface.
2. Apply minimum pressure to the work surface,
allowing the tool to operate at high speed.
Grinding rate is greatest when the tool operates
at high speed.
3. Maintain a 20° to 30° angle between the tool
and work surface.
4. Continuously move the tool in a forward and
back motion to avoid creating gouges in the
work surface.
5. Remove the tool from work surface before
turning tool off. Allow the tool to stop rotating
before laying it down.
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 D WALT repair agent.
e
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.
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
e
to 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. Be sure
the trigger switch is in the OFF position.
An accidental start-up can cause injury.
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 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.
