Squeegee Support

Check

(to perform every

150h

)

The squeegee support has to be com-
pletely free to move to lie perfectly on the
floor. It is important that it can rotate
freely and it is properly pressed on the
floor by the gas spring.

Maintenance

(to perform every

600h

)

• Put the machine in safe conditions.

• Remove

the

squeegee

from

the

squeegee support.

• Remove and replace the squeegee

support wheels loosing the adjust-
ment wing nuts and the squeegee
wheels screws

(see fig.

7.4.2-9

)

,

(see section

4.3.2

at page

23

)

• Proceed at reverse to reinstall the

parts.

• During the assemblying lubricate

the squeegee support eyelet.

7.4.2-8

7.4.2-9

• At the end of the assemblying per-

form the proper squeegee adjust-
ment

(see section

7.3.1

at page

53

)

.

7.4.3

Vacuum Hose

Check

(to perform every

4h

)

The vacuum hose

(see fig.

7.4.4-10

)

, has to be

clean and intact. It is mandatory that
the hose has no crack to not decrease
the vacuum. To verify the vacuum hose
goodness turn on the vacuum motor and
block the lower part of the hose with the
hand, in this way there must be no air
passage.

7.4.4

Drain Hose

Check

(to perform every

4h

)

The Drain Hose and its Cap has to seal
perfectly the hose to avoid any pressure
drop or dirty water leakage. The drain
plug

(see fig.

7.4.4-11

)

must have a perfect

seal to avoid leakage of recovery water
or loss of vacuum. The Drain Manifold
has to be flexible and has to have no
cracks to avoid any break down during
the bending to drain the machine.
