Operation
Removing a Drum
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 6.
1. Relieve the Pressure.
2. Press in and hold the air-assist valve (47) until the
inductor plate rises above the drum. Release the
valve.
3. Open the snap-over valve (27) and raise the
elevator to full height.
NOTE: If you lose air pressure when reaching the
drum chime, continue holding the air-assist valve and
slowly pull out the snap-over valve until the chime is
passed. Then, immediately close the snap-over valve
to prevent raising the drum off of the floor.
