Raising the Platen when there is a Container

To prevent damage to the sealing rings, make sure you do the following

steps when attempting to raise the platen from an adhesive container.

Step 1 - Make sure the platen is hot enough so that none of the adhesive

sticks to it. From the Home screen, touch the Platen button then Adjust Set

Point.

Step 2 - Use compressed air from beneath the platen to help the heated

platen raise itself up. This process is called Aerating the Container. The

following section details this procedure in greater detail.

Aerating Container

WARNING! Risk of injury! Do not use an external source of compressed air

for aeration. Excessive pressure could damage both the platen the adhesive

container.

1. Make sure the selector Raise/lower platen (2) is set to 0.

2. Remove the rod (4) out of the aeration connection.

Lowering Platen

When lowering the platen into an adhesive container, you must always

deaerate or let any air escape from under the platen.

1. Set selector Raise/lower platen (1) to Lower.

2. Place a drip pan under the air relief valve (3).

3. Unscrew the rod (2) somewhat to open the air relief valve.

4. Press both buttons on the two-hand control at the same time (within 0.5

seconds) until the platen is inside of the container. The downward motion

continues on its own now.

rod back into place.
