Test: Arms ‘Up’ Locked Out by Packer Panel Not Home
The packer panel triggers a proximity switch in the fully forward or ‘home’ position. This proximity
switch, when triggered, allows the operator to raise the arms. If the proximity switch is not triggered,
the operator can only raise the arms until they trigger overheight proximity switch #1, which roughly
corresponds to the arms being at a height that puts the fork pivot tube above the cab windshield. This
lockout prevents the operator from dumping a container behind the packing panel.
For this test, proceed as follows:
1. With the arms down, activate the ‘Auto Pack’ function and then depress the ‘Pump Shutoff’
switch. The packing panel will stop.
2. Pull out the ‘Pump Shutoff’ switch to engage the pump, and raise the arms as far as they will go.
3.
The arms should stop when the fork pivot tube is approximately at the level of the top of the cab
windshield.
4.
If the arms travel all the way to the dump position, refer to the Proximity Switches section in the
Maintenance Manual
.
Test: Arms ’Up’ Locked Out by Top Door Not Open
The top door triggers a proximity switch when it is fully open. When this proximity switch is
triggered, it allows the arms to lift and dump a container. If the proximity switch is not triggered, the
operator can only raise the arms until they trigger overheight proximity switch #1, which roughly
corresponds to the arms being at a height that puts the fork pivot tube above the cab windshield. This
lockout prevents the operator from dumping a container with a closed or partially closed top door,
which would cause serious damage.
For this test, proceed as follows:
1.
With the arms down, activate the top door ‘Close’ function so that the door is partially closed.
2. Raise the arms as far as they will go.
3.
The arms should stop when the fork pivot tube is approximately at the level of the top of the cab
windshield.
4.
If the arms travel all the way to the dump position, refer to the Proximity Switches section in the
Maintenance Manual
.
Test: Joystick Locked Out by Body Raised
On full eject units with service hoist, the body triggers a proximity switch when at rest on the chassis
frame. This proximity switch, when triggered, allows movement of the lift arms only when the body is
down on the chassis frame. This lockout prevents the lift arms from damaging the chassis cab.
For this test, proceed as follows:
1. With the arms raised completely and the forks stowed in the hopper, raise the hoist or service
hoist so that the body raised proximity switch is not triggered.
2. Activate arms ‘down’. The arms should not move.
3.
If the arms move, refer to the Proximity Switches section in the Maintenance Manual .
