the hazards and how to avoid them.
• Abide by the current OSHA lockout/tagout standard when lockout/tagout is called for in
the service instructions. Outside the USA, abide by the OSHA standard in the absence of
any other overriding standard.
WARNING 19 : Crush Hazards—Tilting machines only—The machine housing will crush
your body or limbs if it descends or falls while you are under it. Housing can descend with power
off or on. Manual operation of tilting valves overrides safety interlocks. Improper operation of
manual tilting valves may cause the housing to descend.
• Secure both red safety supports in accordance with the instructions furnished, then lock
out and tag out power at the main machine disconnect before working under the tilted
machine.
• Do not operate the manual tilt valves with anyone under the machine.
• Do not operate the tilt controls with anyone under the machine.
WARNING 20 : Confined Space Hazards—Confinement in the cylinder can kill or injure
you. Hazards include but are not limited to panic, burns, poisoning, suffocation, heat prostration,
biological contamination, electrocution, and crushing.
• Do not enter the cylinder until it has been thoroughly purged, flushed, drained, cooled,
and immobilized.

procedures. This key switch, located inside the low voltage control box, is shown in
DANGER 21 : Crush Hazard—The "Maintenance Only" position bypasses access panel
interlocks and permits access to moving parts during both manual and automatic operation. To
prevent serious injury or death, comply with, or ensure compliance with the following:
• Never use the machine for normal operation with this switch in the "Maintenance
Only" position.
• Never use this switch to clear faults or for any operational function.
• Use this switch only if you are a trained, authorized service technician, and only when
performing maintenance that requires immediate access to moving parts normally
shielded by the access panels.
• Always turn the switch to the "Safe Operation" position and remove the key before
resuming normal operation or stepping away from the machine.
• Keep the Access Panel Interlock Bypass key secured away from machine operators and all
other personnel who do not fully understand the results of using it.
