18. SOLUTION TANK
Remove the front inlet cap and check the solution fi lter is correctly installed.
Check the solution fi lter cover (beneath the tank) is correctly closed.
19. SOLUTION TANK
• Fill the tank with clean water in the front fi ll location ( 1 ) or at the rear fi ll
location ( 2 ) at a temperature not exceeding 120°F (50°C).
• You can check the level of solution in the tank by means of the rear sight
gauge ( 3 ).
• Add the liquid detergent into the tank, in the concentration and manner
specifi ed by the manufacturer. The formation of excess foam could damage
the vacuum motor, so be sure to use only the correct amount of detergent.
WARNING: Always use low-foam detergent. Introduce a small
amount of defoaming liquid in the recovery tank before starting
to work to prevent foam from being generated.
WARNING: Never use pure acids.
20. ATTACHING THE BRUSHES
A. With the brush deck up, insert the brushes in the brush housing beneath the
deck base, turning them until the three pins enter the notches in the clutch
plate; turn the brush until the pin is pushed towards the coupling spring and
is locked into place. The fi gure shows the brush rotation direction for the
right-hand brush; the left-hand brush rotates in the opposite direction.
WARNING: Make sure there are no objects or people in the vicin-
ity of the brush when doing this operation.
B. Swap the right and left-hand brushes every day. If the brushes are used and
have deformed bristles, it is better to reassemble them in the same position
(the right-hand one on the right, and the left-hand one on the left), to pre-
vent the deformed bristles overloading the brush motor as well as excessive
vibration.
21. REGULATING THE SOLUTION
Regulate the quantity of water with the solution control valve ( 1 ).
