2.2 General
NOTE!
• For reasons of safety, this manual must be
studied before using the product for the first
time.
• Never start the unit before installation is
complete.
WARNING! Risk of personal injury
• Always stop the unit before looking into the
outlet. The fan rotates at high speed and
even small particles of dust could severely
damage the eyes.
• Ensure the dust collector is attached to the
unit’s inlet and the silencer attached to the
outlet. Suction at the inlet is very powerful
and any contact with the fan wheel could res-
ult in severe injury.
• The belt guard must always be fitted except
during maintenance work on the transmis-
sion. Maintenance must be undertaken by
qualified personnel. Refit the guard when the
work is finished. The Figures in this manual
without the guard in place are for illustration
purposes only and do not imply that the unit
ever is to be run without the guard.
• The thermal switches in the unit must always
be enabled. Switch off and lock the mains
maintenance switch or remove the mains
fuses before starting the inspection.
CAUTION! Risk of equipment damage
The dust collector must be positioned before
the vacuum unit. The dust collector must be
designed and maintained to prevent coarse
particles and dust from being sucked into the
fan. The filtering of fine dust must be suffi-
cient to prevent undue wear to the fan. The
unit must be stopped immediately for inspec-
tion by suitably qualified personnel if the fan
rotates unevenly, or if damage to the fan or its
bearings is suspected.
