8.6.1 DAILY OPERATIONS
Disassemble and check the brushes or the scraper
disks (with the abrasive disks mounted).
Check that there are no foreign bodies that may impede
the movement or efficiency of all cleaning parts.
Check the squeegee: clean the blades and check their
condition/wear.
8.6.2 WEEKLY OPERATIONS
Check and, if necessary, replace or adjust the height
of the splash guard.
Carefully check the profile of the squeegee blades and
replace them, if necessary.
Check that the suction hoses and conduits are not
clogged.
Check that the brushes are flat as they work on the
surface (check for any irregular wear on the brushes
or on the abrasive disks).
If necessary, adjust the slant of the action on the floor.
Thoroughly clean the solution and recovery tanks.
8.6.3 OPERATIONS AT EXTENDED INTERVALS
Even though the machine was built with great precision
and conforms to the most severe quality tests, the
electrical and mechanical parts will inevitably be subjected
to wear and aging after extended periods of use.
For safe and problem-free operation, your machine
should be carefully checked every year by our authorised
technical service centre (or by a specialist in the sector
in this manual).
This type of work may have to be carried out more
frequently if the machine operates in particular/difficult
situations and/or if required maintenance was not
performed.
8.7 RECOMMENDED SPARE PARTS
You’ll always be able to use your machine as efficiently
as possible by maintaining a stock of the most common
consumable materials and by scheduling routine and
extraordinary maintenance. Contact your dealer for a
list of these spare parts.
