AUTOMATIC BRUSH ASSEMBLY (ruby50e)
Put the brush onto the floor next to the brush
base.
1. Check that there is the electric supply.
2. Lift the brush base acting upon the pedal.
3. Move the machine so that the brush base
gets over the brush.
4. Lower slowly the brush base acting upon the
pedal and check that it is centred onto the brush.
5. Press the switch of the brush motor.
6. Act shortly onto the lever presence so that
the brush buttons get coupled in their plate se-
ats.
ATTENTION:
Use only brushes supplied with the machine or
the ones indicated in the paragraph “RECOM-
MENDED BRUSHES”. The use of other brushes
can compromise security.
RECOVERY TANK
Check that the cover of the suction filter (1) is
correctly secured, after rotating the levers and
that the suction motor hose (2) is correctly con-
nected.
Verify also that the squeegee hose is correctly in-
serted into the seats (3 and 4) and that the ex-
haust hose plug (5) placed in the front part of the
machine, is closed.
DETERGENT SOLUTION TANK
The capacity of the detergent solution tank is in-
dicated in the technical data.
Open the screw plug (1) placed in the rear left
part of the machine and fill the detergent solu-
tion tank with clean water at a maximum tem-
perature of 50°C. Add the liquid detergent in the
percentage and conditions foreseen by the
manufacturer. To avoid excessive foam presence,
which could cause problems to the suction mo-
tor, use the minimum percentage of detergent.
Screw down the plug to close the tank.
ATTENTION:
Use always low foam detergent. To avoid foam
presence, before starting working operation, in-
troduce into the recovery tank a minimum quan-
tity of anti-foam product.
Never use pure acid.
FLOOR CLEANING
STARTING OF THE MACHINE
The machine is equipped with a mains cable
complete with a plug for the connection to the
mains system and with a socket connector to in-
sert inside the plug (16) situated underneath the
instrument board.
1. Insert the socket inside the machine plug (16).
2. Hook the cable onto the support (17) to avoid
that probable tears can damage the socket.
3. Insert the plug into the appropriate mains
socket and check that on the instrument board
the signal lamp for tension presence comes on
(5).
4. For machines equipped with key switch (see
under "OPTIONAL ACCESSORIES”), turn the key (8)
clockwise to switch on the machine, counter-
clockwise to switch it off.
5. Press the brushes motor switch (1).
6. Press the switch of the suction motor (2) and
this will start to function.
7. Acting upon the solution valve lever (10) ad-
just the solution detergent quantity bringing the
floor uniformly wet, avoiding the leakage of de-
tergent from the splash guards. Always consider
that the correct quantity of solution detergent
depends on type of floor, dirtiness and machine
speed.
8. For machines optionally equipped with sole-
noid valve (see under "OPTIONAL ACCESSORIES")
the flow of detergent solution will be activated
automatically, once the solution valve has been
opened through the lever (10), acting upon the
levers presence (9). On the instrument board the
signal lamp of the open solution valve will come
on (6). Releasing these levers, flow will stop
automatically.
9. Acting upon the brushes base lifting pedal
(12) lower the brushes base.
10. Acting upon the squeegee lifting lever (11)
lower the squeegee.
11. Activating the levers (9), the brushes will start
rotating transferring to the machine a forward
movement. The squeegee will start drying the
floor.
12. During the first meters check that the deter-
gent solution flow is appropriate and that the
squeegee adjustment guarantees a perfect dry-
ing action.
ADJUSTMENT OF THE BRUSHES PRESSURE (OP-
TIONAL)
Through the register (1) placed in the inner part
near the front right wheel, it is possible to adjust
the brushes pressure on the cleaned surface.
By turning the wing nut clockwise the pressure
increases, rotating the wing nut counterclock-
wise, the pressure decreases.
This device allows a more efficient cleaning ac-
tion also on very difficult and dirty surfaces.
BRUSHES MOTOR OVERLOAD PROTECTION DE-
VICE
The machine is equipped with a protection de-
vice (7) that intervenes in case of an overload of
the brushes motor disconnecting the motor. If
the protection device intervenes again and often,
contact the authorized technical assistance.
ATTENTION:
To reset the brushes motor, turn off the brushes
motor switch (1) for a few seconds and turn it on
again, rearm the push button of the protection
device (7).
OVERFLOW DEVICE
In order to avoid serious damages to the suction
motor, the machine is equipped with a float that
intervenes when the recovery tank is full, closing
the suction hose and stopping the suction.
