Foam Marker Operation
Maintenance
Preliminary Checks
After a long period of inactivity, it is recommended to
check the tightness of the seal fittings.
Preparation and Solution
• Pour an amount of concentrated foaming liquid into the
tank according to the instructions given on the package
of the product.
• Add clean water to fill the tank. Use a hose inserted
down to the bottom of the tank to mix the product well
and prevent foam from forming. Otherwise, it is
necessary to mix carefully after filling the tank.
• Screw on the cap and tighten it carefully.
• To use it in wintertime, add windshield washer in the
amounts indicated on the package.
Starting and Operation
• Start up the compressor with the lever selector A, on
the control panel. After a few seconds, the circuit will
reach its working pressure, making foam come out of
the selected foam nozzle.
• Adjust the intensity of the foam outlet, using the flow-
rate regulator on the tank cap.
• During use, it is possible to alternate the right- or left-
hand foam nozzle by moving the selector lever.
• To stop operation of the foam marker, turn the selector
lever to the OFF position (middle).
• To finally stop the supply to the foam marker, turn the
starter key to the OFF position (if the electrical
connections described in the
“Mounting control unit”
section have been made).
Topping up Liquid
• Discharge the remaining pressure from the tank as shown on page 2.
• Refill with liquid, observing the procedures described in the “Preparation and Solution” section.
Flow-rate Adjustment
Pressure Relief Valve
The pressure relief valve on the tank cap needs
no maintenance. Adjusting the pressure discharge
ring under the tank cap prevents incrustations from
forming on the pressure relief valve. At the same
time, it checks efficiency.
