Service and maintenance
). Ob-
Risk of injury, electric shock
Always disconnect the mains plug from the
socket before performing maintenance work on
the machine!
All maintenance and repair work which requires
the motor housing to be opened must only be
carried out by an authorised service workshop.
Damaged safety devices and components must be
repaired or replaced in a recognised specialist
workshop, unless otherwise indicated in the oper-
ating manual.
Observe the following instructions:
– A dust test must be performed at least once a
year by the manufacturer or an instructed per-
son. This test may include checks to determine
whether the filter is damaged, the machine is
sealed properly and the monitoring features are
functioning correctly.
– During maintenance and repair work, all compo-
nents that cannot be cleaned satisfactorily must
be replaced. The old components must be sealed
in impermeable plastic bags prior to disposal in
compliance with applicable regulations for this
type of waste.
– Provided maintenance personnel or other per-
sons in the vicinity are not endangered, the user
must dismantle and clean the machine prior to
performing maintenance work. Appropriate pre-
cautionary measures include decontaminating
the machine prior to disassembly, making provi-
sions for locally filtered forced ventilation at the
location of machine disassembly, cleaning the
maintenance area and appropriate personal pro-
tective equipment.
