To avoid injury due to unexpected machine operation
initiated by a remote controller, disconnect the
customer I/O cable from the system prior to repair.
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as skin injection, splashing
fluid and moving parts, follow the Pressure Relief
Procedure on page 17 and disconnect power from
the system before repairing the equipment.
Removing a pressurized air filter bowl could cause
serious injury. Do not service air filter until air line is
depressurized.
