Clearing a Case Jam
The WEXXAR Model WF-10T Case Formers will provide reliable, trouble-free performance on a
wide variety of case sizes. Occasional jams are not uncommon, but frequent jamming can
usually be traced to a particular reason, such as incorrectly set machine adjustment, and
corrected. Refer to Section 7:
‘Case Size Adjustments’,
Section 8.5:
‘Maintenance Adjustments’
and Section 9:
‘Troubleshooting & Repairs’
for further information.
To place the machine back into service as quickly as possible after a jam has occurred, proceed
as follows:
1.
Press one of the ‘EMERGENCY STOP’ buttons
. This will shut off the electrical and air
power to the machine mechanisms. It may take a few moments for the system air
pressure to decline to zero;
wait approximately 3 seconds, or until air pressure has
fully exhausted and all mechanisms are stationary before proceeding.
2. If required by local regulations or company policy, lock out the electrical power and air
supply before proceeding.
3. Open the guard door for access to the jammed case.
4. Remove all jammed case corrugate. Any mechanism that is entangled with the jammed
case may safely be moved by hand, as all air pressure has been exhausted.
5. Close the guard door and pull out the
‘EMERGENCY STOP’
button. Remove lock-out, if
applicable.
