ADJUSTMENT AND QUALITY
Your OLIVER Model 1308 was tested at the factory using Oliver trays and film.
NOTE
THE TEMPERATURE CANNOT BE ADJUSTED BY THE OPERATOR
The heater platen temperature is factory set at approximately 300°F (Approx. 150°C).
Contact the Oliver Service Department if you suspect the heated platen temperature is
not correct.
It is necessary to periodically check for a proper seal. This can be done by pull the film
over an empty tray carrier, sealing it like normal and peeling the film. If there is a proper
seal, the pattern on the film should be a complete outline of gasket material provided.
A poor seal will occur if the product in the tray contaminates the tray flange or the
pressure generated by the sealing mechanism is less than 15lbs. The pressure can be
adjusted by removing the acorn nut atop the center arm and giving a few turns to the nut
on the heater adjustment bolt. This will expose more threads between the casting and
the sealing mechanism, therefore, generating more pressure.
Under different operating conditions, it may be necessary to increase or decrease the
sealing time. This is done by varying the length of time the operating handle is in the
down position. Holding the handle down longer makes the seals stronger. Although a
stronger seal may cause shredding or tearing of the film when removing film from tray.

CLEANING AND MAINTENANCE CONTINUED
REPLACING AND CHECKING GASKETS
•If there are any gouges, cuts or gaps in the gasket, the gasket will have to be
replaced.
•Be sure to replace all the gaskets not just the piece that is damaged.
•When reinstalling gaskets, the gasket must be seated all the way down in the
groove.
•Do not stretch gasket when reinstalling.
•After the new gaskets are installed, place the tray carrier up side down on a flat
surface and check to see if the newly installed gasket is even.
•If not even, depress or lift gasket to provide an even heat sealing surface.
•It is necessary to periodically check for a proper seal. This can be done by pull
the film over the empty tray carrier, sealing it like normal and pulling the film. If
there is a proper seal, the pattern on the film should be a complete outline of the
edges of the tray.
