MACHINE MAINTENANCE
Routine maintenance is critical to ensure proper
machine operation and cleaning performance.
Perform all maintenance procedures as follows.
Always turn OFF all machine switches before
performing any maintenance.
Adjusting the Squeegee Assembly:
As the machine is used, the squeegee blades will
wear or need to be replaced due to damage. Some
adjustment may be needed.
•
Squeegee blades should lie over slightly (like a
window squeegee) when the machine is moving
forward or in reverse.
•
Adjust the blade angle by turning the wing nut on
the pivot arm clockwise/counterclockwise.
Daily Maintenance
Solution and Recovery Tanks
•
Drain the solution tank through the solution valve or
the sight hose at the rear of the machine.
•
The recovery tank is emptied through the black
hose at the rear of the machine. Remove the plug
and drain the liquids according to your local EPA
regulations.
•
Every time
you empty the recovery tank, we
recommend that you add at least 4 to 6 ounces of
defoamer chemical into the recovery tank before
resuming work. Vacuum the defoamer into the
empty recovery tank through the squeegee vac
hose.
•
At the end of the day empty all liquids from both
solution and recovery tanks. Rinse both tanks with
clean water to prevent chemical residue build-up,
allow to air - dry to prevent odors.
•
Leave lid off recovery tank to prevent moisture from
building up.
•
Remove any residue from screen and float ball to
ensure proper operation. Replace float assembly
in recovery tank.
•
Check clear lid for airtight seal.
•
Check the drain hose for damage and / or
restriction, to access the hose, remove the clean
out cap from inside the Recovery tank, replace the
cap before using the machine.
Pad Drivers or Brushes
•
Remove either pad drivers or brushes from
machine after use.
•
Rinse with clean water to prevent chemical residue
build-up.
•
Allow to air-dry, on a peg or upside down on a
shelf.
•
Inspect for wear or damage. Repair or replace as
needed.
Squeegee Assembly
•
Remove squeegee assembly from machine.
•
Rinse with clean water to prevent chemical residue
build-up.
•
Allow to air dry, it can be stored on top of the
machine for drying.
•
Inspect the squeegee assembly, linkage, and
vacuum hose, for wear, damage or obstruction.
Repair or replace as needed.
