Operation

Port A scrub 14

Wet cleaning of hard floorings requires equipment with
squeegee and brushes suitable for the type of floor to be
cleaned.
Therotating brushes and the cleaning lye scrubthedirtandclean
the floor thoroughly while the squeegee collects the lye
immediately. The floor is dry and clean can be stepped on
immediately.

Useful advice for optimum cleaning

Before wet cleaning, sweeping the floor is required. This is not
only to improve the cleaningeffect but to significantly reduce the
wearingof the machine.

In case of heavy soiling or for wax removal (basic cleaning), a
second treatment of the floor may be required. In the first cycle,
the floor is scrubbed with a detergent solution adopted to the
degreeof soiling.

This cleaning agent acts on the floor according to the
specificationsofthemanufacturerfor about 5 to 10 minutes,then
scrubthe floor gain with thesqueegeebeinglowered.

Comply with the instructions for correct dosage of
detergent. Correct dosage will help you save money
And protect the environment.

Working Principle

Occurrence of great quantities of foam will affect functioning of
your machine.

Actually, it indicates excessive dosage or improper suitability of
dosing and degree of soiling. Unused detergent particles in the
soiled water lead to formation of foam. Refer to the detergent
reservoir for information on correct dosage. Take the
manufacturer’s recommendations as a first basis. Test made by
yourself in practice will help you find the ideal type of detergent
andthe perfect dosage applicable toit.

Proceed thus as follows at the end of operation

- Take the machine into park position

- Turn suction motor on

- Move the machine a little bit forward

During this movement, the rear squeegee takes in the water.
