MANUAL BUSH INSTALLATION
•Use lever (1) to lift the base (lever downwards).
•Turn key (2) to OFF and remove it from the control panel (installing the brushes
with power on may cause injury to the hands).
•With the base raised thread the brushes into the seat on the plate below the base,
turning them until the three buttons enter the holes on the plate. Turn them abruptly
to push the button towards the retaining spring so that the brush locks in place. The
photo shows the direction of rotation for installing the right brush. Rotate the
opposite direction to install the left brush.
•For the single brush models the procedure is the same and the rotation direction for
the brush coupling is indicated on the picture.
•(Only for double brush machines) we recommend inverting right and left brushes
every day and vice versa. If brushes are not new and have distorted bristles then it
is best to install them always in the same position (the right brush on the right side
and the left brush on the left side) to prevent bristles with a different slope from
overloading the brush motor and causing excess vibrations.
ASSEMBLY OF THE BRUSHES WITH AUTOMATIC COUPLING-
RELEASE
(Optional) Place the brushes under the base after taking out the splashguard with the
proper spring hook, so that the brushes are centred with the brush holders. This
assembly can also occur placing the brushes under the base and moving forward the
machine until the brushes are dragged along by the machine, which means that they
are automatically centred under the brush holders (only on machines provided with
the OPTIONAL automatic coupling system). Pushing the control lever, lower the
base. Now just switch on brush motor and they will be automatically fastened to
brush holders and work can start.
RECOVERY TANK
Open hood (1). Check:
•That plug (2) is properly anchored (it must not pull out when it is lifted, otherwise
turn it clockwise)
•That aspiration tube (3) is inserted in its seat.
SOLUTION TANK
Fill the solution tank with clean water at a temperature not in excess of 50°C. Add
liquid detergent in the amounts and using the procedures recommended by the
detergent manufacturer. Use only a minimal percentage of detergent to prevent
formation of an excess quantity of foam since too much foam may damage the
vacuum motor.
NOTE:
Always use low-foam detergent. Introduce a small amount
of anti-foam detergent in the recovery tank before starting to work. Be sure to
prevent foam from being generated.
Never use pure acids.
