Recovery Tank Float Shut-off
When water is no longer being vacuumed from the floor
and the vacuum fan is operating, the ball float has
engaged. The vacuum motor will not vacuum water
with recovery tank full. The recovery tank must be
drained.
1. The float shut-off screen can be cleaned in or out
of the machine.
2. To clean the float shut-off while it is inside the
machine wipe material off screen then rinse. Check
that the ball is also clean and moves freely.
3. To remove the float shut-off, grasp the screen with
one hand and the connected tube with the other.
Tilt and pull the float screen assembly to pull it off
the barb on the tube.
4. To install, place one hand on the tube, and then tilt
and push the float screen assembly over the barb
on the tube.

Vacuum Motor Carbon Brushes
Carbon
Brushes
End Cap
If armature commutator is grooved, extremely pitted or not
concentric, the motor will need to be replaced or sent to a
qualified service center.
Inportant:
These brushes wear quicker as the length shortens due to
increased heat. Spring inside brush housing will damage
motor if brushes are allowed to wear away completely.
Periodically check the length of the carbon brushes. Replace
both carbon brushes when either is less tan 3/8" (9.5mm)
long.
