switch is in the off position by pressing
the rear part of the switch and releasing.
Ensure the slider switch is in the off
position as described above after any
interruption in power supply to the tool,
such as the activation of a ground fault
interrupter, throwing of a circuit breaker,
accidental unplugging, or power failure.
If the slider switch is locked on when the

Spindle Lock (fi g. 1)
The spindle lock (a) is provided to prevent the
spindle from rotating when installing or removing
wheels. Operate the spindle lock only when the tool
is turned off, unplugged from the power supply, and
has come to a complete stop.
NOTICE: To reduce the risk of damage
to the tool, do not engage the spindle
lock while the tool is operating. Damage
to the tool will result and attached
accessory may spin off possibly
resulting in injury.
To engage the lock, depress the spindle lock button
and rotate the spindle until you are unable to rotate
the spindle further.
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 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.
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 DEWALT power tool has been designed to
operate over a long period of time with a minimum

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
