Continue to push the drum separation air button
(Fig. 26) only enough to keep the drum from rising

WARNING
Excessive air pressure in the material drum could
cause the drum to rupture, causing serious injury.
The ram plate must be free to move out of the
drum. Never use drum separation air with cold
adhesive or a damaged drum.

Positive pressure is released from the drum when
the ram plate seal is pulled clear. Always wear
protective clothing and stand directly in front of the
ram control box when removing the drum.

Once the follower plate leaves the drum, place the
drip tray in the brackets provided.
WARNING
Never reach under the heated follower plate after it
leaves the drum. Serious burns could result from
dripping materials.

Follow the steps in MATERIAL LOADING
(page 12) and PUMP BLEEDING (page 16).
NOTE:
It is only necessary to lubricate the follower
plate tire seals on initial material loading.
