FIRST OPERATION
After Unpacking
Verify the machine and accessories with the invoice copy.
Check the machine for any transit damage, if found contact
the branch/dealer immediately.
Owner's personnel are not allowed to unpack the
machine.
Identification of Main Parts
Comply with instructions for correct dosage of cleaning
solution. Correct dosage will help optimize costs and also
minimize impact on the environment. Too much foam can
affect the performance of the machine.
Principle of Operation
A squeegee and suitable brushes or pads are required for wet
cleaning of hard floorings. The rotating brush scrubs the floor
thoroughly, removing dirt through suds, thereby cleaning the
floor. The dirty water is drawn during the same cycle through
the squeegee. Thus, the floor can be walked on immediately
after it is dry and clean.

Useful Tips:
ŸPrior to wet cleaning, it is necessary to sweep the floor.
ŸThis way, not only is the cleaning efficiency improved, but
wear of the brush is also substantially reduced.
ŸIf floors are particularly dirty or if wax has to be removed
(basic cleaning); the floor must be treated twice.
ŸDuring the first cycle, the floor is scrubbed with the
cleaning agent selected according to the degree of dirt
encountered, the squeegee remaining lifted.
ŸAllow the cleaning agent to act on the floor for approx. 5
or 10 minutes, complying with the manufacturer's
instructions.
ŸScrub the floor once again while the squeegee is lowered.
ŸToo much foam indicates excessive dosage or improper
suitability of cleaning solution for the existing kind of
dirt.
ŸCleaning solution particles contained in the soiled water
that are not used will cause formation of foam.
ŸInstructions for dosage are given on the cleaning solution
tank and must ideally adhere to manufacturer's
recommendations.
ŸThe ideal type of cleaning solution and the perfect dosage
applicable to it will come through sustained use of the
machine.
