Description; Technical Data - Nederman VAC 20 Manual De Instrucciones

WARNING!
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!
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 sufficient to prevent undue wear to the fan.
The unit must be stopped immediately for inspection by suitably qualified personnel if
the fan rotates unevenly, or if damage to the fan or its bearings is suspected.
