SECTION 4-22
Setting and Adjusting the Rear Chamber Pneumatic Cylinder
OVERVIEW
Proper adjustment of pneumatic cylinder is important to performance and safety. Improper settings can
result in premature failure of the jackscrews.
To avoid severe damage to the cylinders, BE PREPARED TO SHUT THEM DOWN IMMEDIATELY
WHEN THE CHAMBER IS MOTIONLESS FOR ANY REASON WHILE THE MOTORS ARE
RUNNING. This condition can occur when the chamber jams on debris or when the chamber reaches
the end of its stroke, whether on the opened or closed end of the stroke (if the limit switches are not
properly adjusted).
TURN OFF AND LOCKOUT the power per OSHA 1910.147 OR ANSI Z244.1-1982 (Lockout/Tag-
out of Energy Sources).
If it is not possible to lock out the power, have an electrician remove the fuses.
Make sure the rotor has come to a complete stop.
The pneumatics, which open the rear of the machine, should not operate until the power is completely
off. If you discover that the pneumatics DO operate while the power is still on, immediately shut down
the machine and call for maintenance to adjust it.
Wear gloves to protect against injury from the rotor or bed knives.
