General Maintenance 85
This safety feature is provided to warn people around that the vehicle is in the process of being
unloaded and to remind the operator that the body is still raised.
To adjust the body raised limit switch:
1. Loosen the limit switch nut.
2. Move the body to the approximate position where the switch is to be triggered. The warning
buzzer shall sound as soon as the body has reached a certain height above the chassis (usually
about 12 inches above the chassis).
3. Tighten the nut.
4. To fine tune the adjustment, loosen the nut slightly.
5. With a flathead screwdriver, turn the adjusting screw located at the center of the nut until a click
is heard.
6. Tighten the nut.
7. Test the operation.
8. If necessary, repeat steps 1 through 7.
Adjusting Tailgate Unlocked Proximity Switch
AUTOMIZER™ vehicles are equipped with a tailgate unlocked proximity switch on the tailgate left side
near the upper end of the tailgate cylinder (see Figure 3-86) [one on each side of the tailgate in co-
mingle units]. This switch gets triggered (amber light lights up) when the cylinder casing is
sufficiently near the switch head. This occurs when the cylinder is fully retracted.
When the tailgate is unlocked/open, the tailgate cylinder is partially/fully extended and no triggering
of the proximity switch occurs; the cylinder having moved downward away from the switch
1
. This
activates the backup alarm and a warning buzzer inside the cab. This also turns on the T
AILGATE
UNLOCKED warning light in the cab and disables packing.
When the tailgate is closed/locked, the tailgate cylinder is fully retracted and triggering of the
proximity switch occurs; the cylinder having moved upward toward the switch
2
. When the switch is
triggered, the warning buzzer and backup alarm stop sounding, the T
AILGATE UNLOCKED warning
light turns off and packing operation can resume.
However, some troubles may occur if the tailgate unlocked proximity switch is out of adjustment. For
example, the tailgate is locked but the in-cab buzzer is still sounding or the T
AILGATE UNLOCKED
warning light is off while the tailgate is still open. In such cases, adjusting the tailgate unlocked
proximity switch is required.
Warning!
Ensure that no one is standing behind or near the tailgate when performing this
procedure.
1. The first thing the tailgate cylinder does when the operator presses and holds the TAILGATE UP switch is to unlock the tailgate, resulting in
the cylinder head moving away from the proximity switch, thus making triggering no more possible.
2. The last thing the tailgate cylinder does when the operator presses and holds the TAILGATE DOWN switch is to lock the tailgate, resulting in
the cylinder head moving closer to the proximity switch, thus making triggering possible.
