Brush Assembly / Disassembly; Machine Transport; Squeegee Assembly; Squeegee Disassembly - Lavor DYNAMIC A4 Manual De Instrucciones

• Follow the steps indicated in the battery manufac-
turer's operating and safety manual (see the battery
maintenance section).
If the machine is equipped with gel batteries (main-
tenance free), follow the instructions indicated here
below.
If the machine is equipped with Pb-Acid batteries,
use a hydrometer to check the element liquid intensity
on a regular basis: if one or more elements are dis-
charged and the others fully charged, the battery has
been damaged and should be replaced or repaired
(refer to the battery service manual).
Close the element plugs and lower the top tank.
Hold the connectors with the hands; don't pull them
using the cables.

BRUSH ASSEMBLY / DISASSEMBLY

• Never use the machine if the brush or the pad
holder with abrasive pad is not perfectly installed.
Assembly:
Place the brush on the floor;
lift the squeegee using the lifting/lowering lever
(Foto B-19*).
Holding the handlebar (Foto C-20*) push it down-
ward in order to lift the front part of the machine
by rotating it on the rear wheels (Foto C-20*);
move the machine and place it over the brush, tak-
ing care that the coupling flange on the brush is
under the metal coupling of the machine.
Switch on the machine using (Foto E-32*) the
general ON/OFF switch on the control panel (Foto
E-13*) .
Select the brush rotation with the brush switch
(Foto E-33*) and start the brush rotation pulling
the control lever (Foto A-2*) : the brush will couple
automatically.
To assemble the pad holder follow the same pro-
cedure.
• Do not allow the length of the rows of brushes
to become lower than 1 cm.
• Do not allow the thickness of the abrasive disks
to become less than 1 cm.
Working with excessively worn brushes or exces-
sively thin abrasive disks may damage the machine
and the floor.
Regularly check the wear on these parts before
starting to work.
Disassembly or replacement:
Lift the squeegee using the lifting/lowering lever
(Foto B-19*)
Holding the handlebar (Foto C-20*) push it down-
ward in order to lift the front part of the machine
by rotating it on the rear wheels (Foto C-20*);
Select the brush rotation with the brush switch
(Foto E-33*) and start the brush rotation pulling
the control lever (Foto A-2*) while holding the
machine lifted up; release the control lever to stop
the rotation: the brush will unhook automatically.
To disassemble the pad holder follow the same
procedure.

MACHINE TRANSPORT

To transport the machine while not working, pro-
ceed as follows:
Switch OFF the machine using (Foto E-32*) the
general ON/OFF switch on the control panel (Foto
E-13*) .
lift the squeegee using the lifting/lowering lever
(Foto B-19*).
Holding the handlebar (Foto C-20*) push it down-
ward in order to lift the front part of the machine
by rotating it on the rear wheels;
While holding the machine in this position, push
it to the new working area or to the parking area.

SQUEEGEE ASSEMBLY

Lower the squeegee using the specific lever (B-19*).
Put the two fixing pins of the squeegee (Foto
G-28*) inside the holes in the squeegee support
(Foto G-44*) .
Screw the two knobs (Foto H-45*) in order to se-
cure the squeegee to the support (Foto H-28*) .
Connect the suction hose coming from the ma-
chine to the suction coupling pipe on the squeegee
body (Foto H-27*) .

SQUEEGEE DISASSEMBLY

Lower the squeegee using the specific lever (B-19*).
Disconnect the suction hose from the coupling pipe
on the squeegee body (Foto I-27*) .
Unscrew the two knobs (Foto I-45*) that secure
the squeegee to its support.
Lift the support of the squeegee (Fotp L-40*).
Remove the squeegee.
7.6 SQUEEGEE BLADES DISASSEMBLY /
ASSEMBLY
Disassemble the squeegee from its support ( see
7.5).
Unscrew the knobs (Foto D-31*) and remove metal
blade retainer (Foto D-30*).
Extract the fixing bolts (Foto D-24*) and remove the
front metal blade retainer (Foto D-25*);
remove the squeegee rubber blades tearing them
from a side.
To replace the squeegee rubber blades, follow the
same procedure on the contrary starting from the
front blade;
lock the fixing bolts (Foto D-24*) retaining them in
the squared seats in the squeegee body;
