Frequently Asked Questions
Q: What does LMS stand for in the TO 00591-41779-81 switch designation?
A: LMS typically indicates a Limit Switch or Load Monitoring Switch in Toyota equipment terminology. The TO 00591-41779-81 is likely a safety or position-sensing switch used in electric lift truck limit circuits to detect mast height, load presence, or mechanical stops.
Q: Where is the TO 00591-41779-81 LMS switch installed in a Toyota lift truck?
A: Limit switches in Toyota lift trucks are typically mounted on the mast structure, tilt cylinders, load wheels, or hydraulic circuits to detect maximum lift height, load conditions, or mechanical limits. Exact location varies by truck model and configuration.
Q: What electrical specifications does the TO 00591-41779-81 have?
A: Contact closing and opening voltages, amperage, and switching frequency depend on the specific Toyota truck model and control system. Provide your truck model and serial number for detailed electrical specifications.
Q: How does a failed TO 00591-41779-81 LMS switch affect truck operation?
A: A failed limit switch may cause loss of load-sense feedback, inability to detect maximum lift height, disabled safety interlocks, or uncontrolled mast movement. This creates operational hazards and may trigger control system fault codes.
Q: Is the TO 00591-41779-81 used in multiple Toyota lift truck models?
A: Toyota OEM switches may be used across multiple platform generations if electrical and mechanical interfaces remain compatible. To confirm which models use this specific part number, reference your truck documentation or provide us your model and serial range.
Q: How do I test if the TO 00591-41779-81 LMS switch is functioning correctly?
A: Limit switches can be tested using a multimeter to verify circuit continuity when the mechanical actuator is depressed and released. Compare actual measured resistance and switching points against Toyota specifications for your truck model.
