body of the tool firmly to maintain
control of the tool at start up and during
use and until the wheel or accessory
stops rotating. Make sure the wheel has
come to a complete stop be fore laying
the tool down.
CAUTION: Allow the tool to reach full
speed before touching tool to the work
surface. Lift the tool from the work
surface before turning the tool off.
SPINDLE LOCK
The spindle lock (d) 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.
CAUTION: 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 D
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 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.
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.
