REGULATING PRESSURE
AND USING STEAM
(If available)
This chapter concerns only
those models provided with
the "pressure regulating" de-
vice. The pressure regulator,
fig. 11, allows the operator to
adjust the working pressure.
When knob C is turned in
an anti-clockwise direction
(B) (minimum), the working
pressure is reduced.
Turn the thermostat knob "B"
(fig. 6 on page 21) to steam
position to obtain an increase
in the temperature of the water
at delivery.
At work temperatures higher
than 95°C (203°F), the work
pressure must be < 32 bar
(460 PSI).
Use the steam nozzle (sup-
plied as an accessory).
During use with boiling water, "Steam Phase", keep
!
away from the openings for fumes discharge (risk of bur-
ning).
When you have finished using the "Steam Phase", turn
the thermostat knob "B" to position "0" (fig. 6 on page 21)
and let the machine cool down for about 3 minutes with
the gun turned on.

when work is over or for storage, antifreeze must be used to
prevent serious damage to the hydraulic circuit.
