WARNING! Risk of eye 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.
WARNING! Risk of cutting injury
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 result in
severe injury.
WARNING! Risk of personal injury
The belt guard must always be fitted except
during maintenance work on the transmission.
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.
WARNING! Risk of electric shock
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.
