SECTION 5 - LMIS SERVICE AND MAINTENANCE
5.1 AUTO-DIAGNOSTIC SYSTEM
The LMIS is equipped with an auto-diagnostic system which is able to detect faulty
pressure transducers, boom angle/length sensors, broken cables or internal
electronic faults.
When the alarm sounds, the display shows an alarm message. If an alarm code
sounds apply the park brake, shift the transmission into “Neutral”, lower forks or
attachment to the ground and shut off the engine. Restart the engine.
If the alarm code persists, refer to “Alarm Codes” on page 5-2. For troubleshooting
information, refer to the appropriate machine service manual.
For additional information, contact your local authorized service distributor.
