Testing Procedure:
1.
Open the side access door approximately 2" (5 cm) and attempt to operate any hydraulic
function. All hydraulic functions should be disabled.
Caution!
Injury or death may occur if you attempt to enter the body while the packer blade or arms
are working.
If all hydraulic functions are not disabled, it may be that the proximity switch is not adequately
adjusted.
To adjust the side access door proximity switch:
1.
Complete lockout/tagout procedure (see Lockout/Tagout Procedure on page 37).
2.
Loosen the proximity switch mounting nuts. Slide the switch forward or backward in the mount
to achieve a gap of approximately 1/4" with the tab.
3.
Tighten the proximity switch nuts.
4.
Test the operation.
