Component Locations
Impeller and Filter System
The Impeller Assembly houses the dust control
vacuum motor and is mounted in the Hopper
Cover
. The Impeller Assembly pulls air from
the hopper through the lter. The ltered air
is exhausted through Vents in the front of the
Hopper Cover.
The rectangular Dust Control Filter seals
against the Upper Hopper and is held in place
by the Filter Shaker Assembly.
The electric motor in the Filter Shaker Assembly
drives two eccentric weights to vibrate or
“shake” the Dust Control Filter to dislodge dust
and allow it to drop down into the hopper. Two
Thumb Nuts secure the Filter Shaker Assembly
and Dust Control Filter to the Upper Hopper.
