FREQUENT INSPECTION CHECKLIST
M ODULE L ATCH C OMPONENTS
Maintaining the module tray latch components in good condition is essential to good
performance and service life. Failure to detect worn out latch components may result in
module trays opening unexpectedly, creating an unsafe operating condition.
1. Inspect each module tray rotary latch and related components for wear and proper
adjustment. Tighten any loose fasteners.
2. Lubricate each module tray rotary latch. Using light oil, apply a few drops to each of
the springs and to the sides of the rotary latch mechanism.

Maintaining the limit switches is
essential to safe operation and good
machine performance. Operating the
machine with a faulty limit switch could
result in reduced machine performance
and a potentially unsafe operating
condition.
Perform these procedures with the
machine on a firm, level surface that is
free of obstructions.
