7.8 PERIODIC MAINTENANCE
For all the operations described herein, refer to the
instructions and detailed warnings in the relative
sections.
7.8.1 DAILY OPERATIONS
Disassemble and check the brush or the pad driver
disk (with the abrasive disks mounted).
Check that there are no foreign bodies that may im-
pede the movement or efficiency of all cleaning
parts.
Check the squeegee: clean the blades and check
their condition/wear.
If Pb-Acid batteries are used, carefully carry out the
operations described by the battery manufacturer.
Charge the batteries.
7.8.2 WEEKLY OPERATIONS
Check and, if necessary, replace 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;
Thoroughly clean the solution and recovery tanks.
For other models with the Pb-Acid battery: check
the level of the electrolyte in all elements and, if
necessary, top up with distilled water. Refer to the
battery manufacturer's detailed instructions.
Lift the filter compartment cover and check under
the impermeable sponge filter for any signs of liq-
uid; if there is any, drain it off into the dirty water
tank.
7.8.3 OPERATIONS AT EXTENDED INTER-
VALS
Even though the machine was built with great pre-
cision and conforms to the most severe quality
tests, the electrical and mechanical parts will in-
evitably be subjected to wear and aging after ex-
tended periods of use.
For safe and problem-free operation, your machine
should be carefully checked every year by our au-
thorized technical service centre (or by a specialist
in the sector familiar with all the pertinent safety
regulations contained in this manual).
This type of work may have to be carried out more
frequently if the machine operates in particular/dif-
ficult situations and/or if required maintenance was
not performed.
7.9 RECOMMENDED SPARE PARTS
You'll always be able to use your machine as effi-
ciently as possible by maintaining a stock of the
most common consumable materials and by sched-
uling routine and extraordinary maintenance. Con-
tact your dealer for a list of these spare parts.
