Maintenance - DeWalt D28116-XE Instruction Manual

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
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 Cleaning under Maintenance for more
information.
Using Flap Discs
WARNING: Shock hazard. 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.
