Test: Auto Pack Function Locked Out by Tailgate Ajar
Each tailgate latch hook triggers a proximity switch when fully closed. These proximity switches, when
triggered, allow the ‘Auto Pack’ function. This feature is included to prevent the operator from activating Auto
Pack at the landfill with the tailgate open, leaving the cab and being struck with ejecting refuse from the body.
For this test, proceed as follows:
1. With the packing panel fully forward to its home position, remove the tailgate lock blocks and
activate the Tailgate ‘Open’ function so that the tailgate is at least partially open.
2. Activate ‘Auto Pack’. The packing panel should not move.
3.
If the packing panel moves when depressing ‘Auto Pack’, refer to the Proximity Switches section in
the
Maintenance Manual
.
Test: Eject Function Locked Out by Tailgate Not Fully Open
Each tailgate latch hook triggers a proximity switch when fully closed. In addition, the tailgate triggers
a tilt switch that senses when the tailgate is fully open. This combination of switches, allow the ‘Eject’
function only when the tailgate is fully open.
For this test, proceed as follows:
1. With the packing panel fully forward to its home position, remove the tailgate lock blocks and
activate the Tailgate ‘Open’ function so that the tailgate is at least partially open.
2. Activate the ‘Eject’ Button. The packing panel should not move.
3.
If the packing panel moves when depressing ‘Eject’, refer to the Proximity Switches section in the
Maintenance Manual
.
Test: Auto Pack and Eject Locked Out by Arms Elevated
The lift arms trigger a proximity switch when being raised to a height that would place the forks over
the legal height of 13’-6”. This arm position roughly corresponds to the fork pivot tube being just
above the cab windshield. The proximity switch, triggered in this position, prevents ‘Auto Pack’ and
‘Eject’ from functioning, and also illuminates the ‘Arms Overheight’ warning lamp. This prevents the
operator from being able to pack with a container in the hopper.
For this test, proceed as follows:
1. With the packing panel fully forward to its home position, raise the lift arms so that the ‘Arms
Overheight’ warning lamp is triggered ‘on’.
2. Activate ‘Auto Pack’. The packing panel should not move.
3.
Next, leaving the arms in their current position, open the tailgate completely.
4. Activate ‘Eject’. The packing panel should not move.
5.
If the packing panel moves when depressing ‘Eject’, refer to the Proximity Switches section in the
Maintenance Manual
