Check if there are any dents on the drum, they could
block the shovel plate of the ram inside the drum.
•
Turn the lifting control lever upwards (
see the illustration
).
•
Acting on the air governor to the ram, gradually increase the
feeding pressure to the pneumatic cylinder till the ram starts
lifting. Let the ram reaches its maximum height.
NOTE
The pneumatic cylinder's speed can be regulated acting on the
adjustable silencer (
I1
) loceted on the ram control lever (see
illustration)

FLAT PRESSING
PROCEDURE IN THE CASK
(FOR EXTRUSION VERSIONS ONLY)
•
Open the primary air supply to the hoist.
•
Turn the valve knob (
J
1
) upward.
•
By turning the adjustment knob (
J
2
) to increase gradually the
supply pressure of the hoist until it starts to rise. (to increase
the pressure, turn the knob (
J2
) clockwise).
•
Let the hoist reaches its highest position.
•
Remove the cover from the frame by 200 litres that you
intend to use.
Check all the fittings for connection of
the various components (pump, hose, gun
etc.), before using the appliance.
Avoid approaching too much to the hoist
during lifting and lowering
Check that the stem does not present
excessive bruising, these can cause the
pressure plate of the hoist with an automa-
tically inside the drum.
•
Place the drum on the ram's plate.
•
Turn the control lever downwards till the shovel plate lowers
near the upper edge of the drum.
•
Stop the descent of the ram by turning the control lever to
the drum correctly so as it is in axis with the shovel plate.
•
Center the drum correctly so as it is in axis with the shovel
plate (
when installed
).
•
Resume the extrusion ram descent, inserting the pump or
the follower plate (
where installed
), inside the drum.
•
Open the bleeder valve placed on the shovel plate, (
when
installed
).
•
Open the ari passage valve of the shovel plate.
•
Allow the compressed air flow into the pump acting on the
air pressure to the minimum valve necessary to a continuous
working.
•
The pump will start working and them will stop when all the
chamber of the product is full. The pump will start working
again any time the trigger of the gun is pushed or the delivery
valve is open.
In case of difficult suction of the pump, slowly open the
bleeder valve placed on the shovel plate and close it when
some product comes out from the vent (
for any possible
working problem, follow the instructions described in the
section "problems and solutionsi"
).
Never let pump idle for a long period: it could
damage the pneumatic motor and ruin the seals.
