MAINTENANCE
Periodically remove the filter inside the dirty water
tank, scrub it with a stiff brush under running
water to remove any accumulated foreign matter.
Note: This operation is very important to
prevent the reduction of the suction
(drying) capability of the squeegee.
The plastic buffles can be easily removed for the
best cleaning of the tanks.
The three solenoid valve bodies may be removed
by turning them through 90 degrees and lifting
them away to reveal the plunger and seating of
each valve. These should be cleaned of scale and
of any other foreign matter.
