ELECTRICS 2.23 When the load on the machine increases from 50% to 80% green indicators (8), (9), (10), (11), (12) and (13) illuminate progressively. When one or two green indicators are illuminated the lift operation is within the machine stability. When all the green indicators are illuminated the lift operation is still within the machines capability but extra caution is necessary. When the amber indicators (14) and (15) illuminate 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 (16) and (17) are illuminated and the audible 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. To restore longitudinal stability to the machine the following steps must be carried out in this sequence. 1. Retract the boom (if boom is extended). 2. Lower boom (if boom is elevated). TESTING AND ADJUSTMENT Troubleshooting Machine preparation for troubleshooting. NOTE: Full rear wheel steering onto the axle stops can give a false reading on the display module. The machine must be prepared correctly before attempting any troubleshooting on the system.
Use the following procedure to prepare the machine. 1. Park the machine on level ground. 2. Engage the parking brake. 3. Retract the boom. 4. Lower the coupler and the work tool to the ground. 5. Stop the engine. Visual inspection Carry out a visual inspection of the main system components before attempting any instrument checks on the system. Use the following procedure to inspect the system.
