To Operate:
(
1) For Dry Pickup (4520W): Install paper bag on inlet inside of tank. Insert the cloth lter assembly in the top
of the tank. Install motor head. The cloth lter located inside the can provides highly e cient separation
of dust and dirt particles from the incoming air stream.
(2) For Wet Pickup: Remove paper bag and cloth lter from tank. Make sure foam lter sleeve is installed on
oat assembly. Make sure oat moves freely. When the liquid level in the tank rises to a point just below
the inlet, the oat assembly shuts o air ow, thus preventing over ow and possible damage to the
vacuum motor.
