IV. Maintenance of Critical
Components
A. Keep Float Switch (fig. 24) Clean
The float switch in your recovery tank
floats up and down with the water level.
When the water level reaches about 3
inches, the float switch activates the dis-
charge pump. Once the dirty water has
been pumped from the recovery tank, the
float switch deactivates the discharge
pump. Any debris that prevents the float
switch from freely rising up and down
with the water level will prevent the float
switch from activating the discharge
pump. When this happens, the machine
will not work properly. Keep the float
switch clean. (Instructions for cleaning
the float switch are found in Section VI).
B. Keep Air Filter (fig. 22 & 23) Clean
If the air filter is allowed to become
filthy, it will affect the machine's ability
to recover water. This will result in poor
drying times. Wipe this filter off every
couple of hours of operation. Remove
and clean this filter once or twice a
month. (Instructions for cleaning the air
filter are found in Section VI).
C. Keep Vacuum Shoe (fig. 26) Clean
If you notice streaking in the carpet,
you may have a clogged vacuum shoe.
Clean vacuum shoe with the shoe hook
and reclean the carpet. When cleaning
the vacuum shoe, also clean the side
vacuum slots. (Instructions for cleaning
the vacuum shoe are found in Section VI).
Another cause of carpet streaking is
moving the machine too slowly during
a cleaning pass. This allows water to
form outside both corners of the nose of
the machine. If this happens, simply in-
crease the speed of your cleaning pass.
