CLEANING RECOVERY TANK

1 Drive the machine to the appointed disposal area.
2 Ensure that the machine is off and the Magnetic
SmartKey (Z) is removed.
3 See Figure 4-1. Pull the Recovery Tank Drain Hose (37)
from its storage area.
4 Direct the hose to a designated "DISPOSAL SITE" and
unscrew the cap (hold the end of the hose above the
water level in the tank to avoid sudden, uncontrolled flow
of waste water). The Recovery Tank Drain Hose can be
squeezed to regulate the flow.
5 Unlatch (36) and lift open the Recovery Tank Cover (20)
set the prop rod (39).
6 Rinse the recovery tank out thoroughly to remove any
and all debris from the tank. To clean out the recovery
tank leave the drain hose open to a floor drain and spray
the inside of the tank clean with a hose. A hose with a
spray attachment can be used to spray out the recovery
tank but should not be directed to the vacuum motor inlet
at the center of the tank. Do not allow sprayed water to
splash outside of tank or into the vacuum motor inlet.
NOTE: The spray hose should not be used to clean the
exterior of the machine near the operator control panel
and sensors to prevent water ingress into sensitive
electronics.
Remove the Debris Catch Tray (23) from the recovery
7
tank. Empty and rinse the debris catch tray then reinstall
it.
Remove any debris that has gathered on the recovery vacuum inlet screen (28). Remove the screen and rinse then reinstall.
8
9 Check the condition of the tank cover gasket (47) and the area it seats against. They should be clean to create a good seal.
NOTE: The Gasket (47) allows the creation of a vacuum in the tank, which is necessary to suck up the recovery water.
10 Close and latch the recovery tank cover.
