Service
With cleaning and maintenance on the machine, the power
cable should be disconnected from the supply.
Th e fi ne fi lter should be changed at least once per year. If
the machine is used with a microfi lter/HEPA fi lter, this
should be changed every 300 running hours. Use breathing
protection when changing the fi lter. Care must be taken
during the fi lter change not to expose unprotected persons
to harmful dust. Used fi lters should be sealed in a plastic
sack and disposed properly.
When changing the fi lters, check the gasket. An unsealed
gasket can cause discharge of whealty dust.
Check regularly that the electrical cable is not damaged.
The DC 2800a/Auto should be performance tested at
least once per year because it may be used with hazardus
materials. Worn parts must be replaced. Dustcontrol is not
responsible for machines that are equipped with other than
original spare parts.
