Squeegee; Accessories; Detergent Solution Filter; Machine Body - LAVOR Pro COMFORT M87 Manuel

Close the pocket using the knobs.
Firmly insert the hose on the squeegee body.

8.3 SQUEEGEE

Do not handle the squeegee with bare hands: wear
gloves and any safety clothing needed to carry out the
operation.
Detach the squeegee from the machine and clean it
under running water using a sponge or a brush.
Check and clean the solid dirt recovery comp artment
and check the passages of the two suction hoses (inlet
and outlet). The hoses have two different diameters to
transfer the greater vacuum at ground level (small
diameter hose from the recovery tank to the inspection
compartment) and to prevent the coarse dirt that
unfortunately may be on the floor from rapidly clogging
the entire suction hose (large hose diameter from the
squeegee to the inspection compartment). Make sure
that the comp artment cover is tightly closed af ter
cleaning: the machine may not dry efficiently if the cover
is not properly closed.
Check the efficiency and the wear on the strip s in
contact with the floor. They are designed to scrape the
film of detergent and water on the floor and to isolate
that portion of the surface to enhance the vacuum of
the suction motor: this ensures that the machine will
dry very efficiently. Working constantly in this manner
tends to round or to deteriorate the sharp edge of the
strip, thus reducing drying efficiently. This is why the
squeegee strips must be replaced.
To replace the worn strap s, follow the instructions in
the relative section. Turn the straps around to wear
down the other sharp corners or to install new ones.

8.4 ACCESSORIES

Remove and clean the brushes or the scraper disks.
° To avoid damaging the floor and the machine,
carefully check if foreign matter, such as metallic parts,
screws, chips, cords or similar items, has become
jammed.
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.
Use only the accessories recommended by the
manufacturer: other products may reduce operating
safety.

8.5 DETERGENT SOLUTION FILTER

Make sure that the detergent solution tank is empty.
Check and clean the solution filter located in the lower
rear part of the machine. Clean with running water if
necessary and check that the detergent solution is
being delivered on the brushes.
Fully tighten the filter to prevent leaks during operation.

8.6 MACHINE BODY

Use a sponge or a soft cloth to clean the exterior of the
machine and, if necessary, a soft brush to eliminate
tough dirt. The machine's shockproof surface is rough
to make it harder to see scratches caused during use.
However, this does not make it easier to remove tough
stains on the surface. Steam machines can be used
34
but it's prohibited to use hoses with running water or
a high-pressure cleaner.

8.7 BATTERIES

8.7.1 PB-ACID
Carry out maintenance operations in accordance with
the manufacturer's instructions and with all the other
instructions provided in this manual.
Exposing the element plates (not completely immersed
in the acid solution) will lead to rapid oxidation and
irreparably reduce the element's operating capacities.
An overflowing acid solution may corrode the machine.
Use battery chargers recommended by the manufacturer
and, in any case, those that are suitable for the type of
battery to be charged.
Always charge batteries in well-ventilated rooms: there
is an explosion risk!
The use of gel or maintenance-free batteries is highly
recommended.
8.7.2 GEL
Carry out maintenance operations in accordance with
the manufacturer's instructions and with all the other
instructions provided in this manual.
Use only those battery chargers recommended by the
manufacturer.

8.8 FUSES AND THERMAL BREAKERS

The machine is equipped with electric protection devices
on the main operating component s to avoid costly
malfunctions. On the main electric board (on the front
of the machine) there are two p airs of general power
strip fuses (2 x 50A) that cut off the battery power supply
when a serious generic malfunction occurs.
The control panel elements are protected by a bayonet
fuse (16A). Instead, under the p anel, there are three
manual reset thermal breakers (40A, 4A, 4A) that trip
(in order from top to bottom) when an overload occurs
on the brush motor (40A), on the squeegee lif t ing system
(4A), and on the brush unit lifting system (4A).
When one of these breakers trip s automatically, the
disabled function can be reactivated by fully depressing
the breaker that tripped.
When the thermal breakers trip, especially when the
machine is used during the first few weeks, it might not
be caused by actual machine malfunctions. However,
a specialised technician should check the device if the
relative breaker continues to trip.

8.9 PERIODIC MAINTENANCE

For all the operations described herein, refer to the
instructions and detailed warnings in the relative sections.

8.9.1 DAILY OPERATIONS

Clean the solid dirt recovery compartment mounted on
the squeegee body.
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.
If Pb-Acid batteries are used, carefully carry out the
operations described by the battery manufacturer.
Charge the batteries.
