Part No 94112
Service
During cleaning and service of the unit, the unit should be
disconnected from the power supply.
Th
e fi ne fi lter should be changed at least once per year. Use
only original parts for replacement. If the unit is equipped
with a HEPA fi lter, this fi lter should be changed every 300
working hours. Use breathing protection and perform this
operation in a contained area. Th
e used fi lter should be
placed in containment and disposed of in the proper and
prescribed method.
Filter change:
Remove the motor head. Lift the fi lter straight up out of the
cyclone. When required, a plastic sack can be placed over
the cyclone for dust-free fi lter change. Th
e fi lter is lifted
directly into the sack.
During the fi lter change, check the fi lter gasket. A dam-
aged gasket can allow the release of hazardous dust. Never
use old gaskets or after-market fi lters. Use only genuine
Dustcontrol spare parts to maintain the unit for use on
hazardous dusts.
Check regularly that the electrical cable is not damaged. Th
e
DC 2800c/Auto should be performance tested at least once
per year because it may be used with hazardous materials.
Worn parts must be replaced.
