(1) This is a green 20% load indicator.
(2) This is a green 40% load indicator.
(3) This is a green 50% load indicator.
(4) This is a green 60% load indicator.
(5) This is a green 70% load indicator.
(6) This is a green 80% load indicator.
(7 and 8) These indicators are amber 85% load indicators.
(9 and 10) These indicators are red 100% load indicators.
(11) The "TEST" switch initiates a self-diagnostic routine test for the display module.
(12) The "DUTY" switch toggles between machine operation with the stabilizers in the raised position, or machine operation with the stabilizers in the lowered position.
(13) This is an indicator that shows machine operation with stabilizers in the raised position.
(14) This is an indicator that shows machine operation with stabilizers in the lowered position.
(15) The "CAL" on/off switch is used to select the calibration mode.
(16) The "SPAN" switch is not used.
(17) The "SPAN + %" switch is used in the calibration mode to obtain the calibration point for setting the indicators.
Indicator (1) through indicator (10) shows the status of the attempted lift operation in comparison to the limit of the machine stability.
As the load on the machine increases from 20% to 80%, green indicators (1), (2), (3), (4), (5) and (6) illuminate progressively. When the load on the machine reaches 85%, amber indicators (7) and (8) illuminate and an alarm will beep at approximately two second intervals. If the load on the machine reaches 100%, red indicators (9) and (10) will illuminate and an alarm will sound continuously. Indicator (1) through indicator (10) should be observed carefully as the load is being raised.
Switch (11) is used in order to test the longitudinal stability indicator. In normal operation, press the "TEST" switch (11) on the front panel of the display module in order to perform a full functional test of the unit. Indicator (1) through indicator (10) will illuminate and the audible alarm will sound when "TEST" switch is pressed.
Depress switch (12) in order to set the longitudinal stability indicator for operation on tires. Duty indicator (13) will be illuminated. Depress switch (12) in order to set the longitudinal stability indicator for operation with lowered stabilizers. Duty indicator (14) will be illuminated.
When one green indicator is illuminated or two green indicators are illuminated, the lift operation is within machine capability. When all of the green indicators are illuminated, the lift operation is still within machine capability, but extra caution is necessary.

Extending the boom or lowering a raised boom further increases the outreach of the load. This can reduce the forward stability of the machine. Machine tip over could result. If the longitudinal stability indicator shows that the machine stability limit is being approached, do not lower or further extent the boom. Retract the boom before lowering. Machine tip over could cause personal injury or death to the operator or other personnel in the work area. |
When amber indicators (8) and (9) are illuminated, the audible alarm sounds intermittently. This indicates that the limit for the longitudinal stability of the machine has been reached. Extra caution is necessary. Do not increase the outreach of the load.
When red indicators (9) and (10) are illuminated and the alarm sounds continuously, the limit for the longitudinal stability of the machine has been exceeded. When this condition occurs do not proceed with the lift operation. Retract the boom if the boom is extended. Lower the boom if the boom is elevated.
The visual alarms and the audible alarm may operate momentarily when the machine is travelling with a load on the work tool which is close to the maximum weight for the machine. This may occur more frequently on uneven ground.
When a reverse force is exerted on the boom green indicators (3) and (4) illuminate. This occurs after the boom has been lowered to the ground and the joystick control is held forward. The system will return to normal operation when the boom is raised. This condition can be avoided if you release the joystick control immediately. When the load is resting securely on the ground, release the joystick control.
