RECOVERY TANK
The recovery tank stores the water solution
picked up by the machine squeegee and vacuum
fan. The recovery tank is located at the rear of the
machine.
The recovery tank should be drained after the
solution tank is empty and whenever the float
rises and stops the water vacuum.
Clean the recovery tank after every work shift. An
inspection door has been provided to make the
tank cleaning job easier. It is located on the top of
the recovery tank.
Keep vacuum hoses clean. Clogged hoses are a
common cause of poor water pickup.
TO DRAIN RECOVERY TANK
1. Stop the engine and set the machine
parking brake.
FOR SAFETY: Before Leaving Or Servicing
Machine; Stop On Level Surface, Set Parking
Brake, And Turn Off Machine.

REAR SQUEEGEE
The rear squeegee channels water into the
vacuum fan suction. The front squeegee blade
channels the water; the rear blade wipes the floor.
Check the rear squeegee assembly for damage,
wear, and adjustment daily.
Rotate or replace the rear blade of the rear
squeegee if its leading edge is worn one-half of
the way through the thickness of the blade.
The rear blade has four wiping edges. To use
them all, start with one wiping edge. To use the
next wiping edge, swap the squeegee
end-for-end. To use the next wiping edge, rotate
the top edges down, bottom edges up. To use the
last edge, swap the squeegee end-for-end.
Replace the back-up strips if they become
damaged, or if they lose their resiliency.
TO REMOVE SQUEEGEE ASSEMBLY
1. Place the squeegee lever in the up position.
2. Stop the engine and set the machine
parking brake.
FOR SAFETY: Before Leaving Or Servicing
Machine; Stop On Level Surface, Set Parking
Brake, And Turn Off Machine.
