12. SOLUTION TANK
Unscrew the water inlet plug and confirm the solution filter, which is located on the
bottom left side, is properly assembled.
13. SOLUTION WATER
Fill the solution tank with clean water at a temperature not more than 50°C/122°F.
Add the proper concentration of liquid detergent by following the manufacturer
instructions. Excess foam in the recovery tank can damage the vacuum motor, so
use only the minimum amount of detergent necessary. Reassemble the cover.
WARNING! Always use low foaming detergent. Adding antifoam liquid
into the recovery tank before cleaning will also help prevent foaming.
NEVER USE PURE ACID.
14. BRUSH ASSEMBLY
1. Lift the brush base with the lift handle.
2. Turn the key to the off position.
3. Place the brushes under the base. Line up the three lugs with the holes in the
brush plate. Insert the brushes into the plate and turn each brush so the lugs are
pushed toward their retaining springs, until clamped in place. The figure shows
the direction of rotation for the coupling of the right brush. The left brush has
to be rotated inversely.
4. Invert the positions of the right and left brushes daily. However, if the brushes
are not new and have deformed bristles, it is better to reassemble them in the
same position. Because the different inclination of the bristles may cause an
overload to the brush motor and excessive vibrations. Refer to the Daily Main-
tenance section for disassembly instructions.
