DC 2900, 15
Part No 94164-A
Service
During cleaning and service of the unit, the unit
should be disconnected from the power supply.
The
fi
ne
fi
lter should be changed at least once
per year. If the machine is used with a micro
fi
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.
Check regularly that the electrical cable is not
damaged. The DC 2900a/c/Auto should be per-
formance tested at least once per year because it
may be used with hazardous materials. Worn parts
must be replaced.
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. The
fi
lter is lifted directly into the sack.
During the
fi
lter change, check the
fi
lter gasket. A
damaged gasket can allow the release of hazar-
dous 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.
For vacuum motor the typical average life of the
original brushes is 600 - 700 hours. They can then
be exchanged or complete motor/fan replaced.
For 2nd brush set life is ca. 400 hours and for 3rd
brush set ca. 300 hours. After that the commutator
is worn out and the motor needs to be replaced.
