Ê The Danger From a Malfunctioning Clutch System
The low speed (wash speed) drive train on machines with multiple motor drives is disengaged during
extract. At the end of extract, the cylinder will slow down before the low speed drive train is permitted to
re-engage. Although extremely unlikely in a properly maintained machine, a malfunction could cause
the low speed drive to engage prematurely (a possibility in all types of industrial machines that utilize
clutches to switch between high speed and low speed operating cycles).
EXPLOSION HAZARD for machines with multiple motor drives—Pulleys
can be spun fast enough to explode into shrapnel-like fragments, injuring
personnel and/or damaging property, if the low speed drive engages dur-
ing or at the end of extract.
☞
IMMEDIATELY shut down the machine if any of these conditions occur:
•
The machine makes a sound like skidding automobile tires as it comes out of
extract,
•
The wash or drain clutch does not disengage or it reengages during extract,
•
V-belts jump off at the start of, during, or at the end of extract,
•
A strange whining sound occurs at any time during extract.
☞
DO NOT permit the machine to operate until the cause of the offending condition
is found and remedied.
