PRIOR TO OPERATION
Install the guard and appropriate disc or wheel. Do not use excessively

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 in the machine becoming
degraded with a potential risk of an electrical shock.
WARNING: 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 in accordance with the below
maintenance instructions.
