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
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 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. See
Maintenance .
