Machine Overview
The Genie S85 is a self-propelled telescopic boom lift designed for high-reach applications with a maximum working height of approximately 91 feet (27.7 meters). It features a self-leveling platform capable of handling up to 500 lbs (227 kg), hydraulic platform rotation of 160°, and fully proportional Hall effect joystick controls. The machine’s design caters to industries demanding vertical access combined with horizontal outreach, such as construction, maintenance, and utilities.
Platform Leveling System and Issue Description
The self-leveling functionality of the Genie S85 platform is governed by sensors and hydraulic controls that maintain the platform horizontal regardless of boom position or vehicle inclination. This system ensures operator safety and stable working conditions at height.
Problems with platform leveling can manifest as uneven or unresponsive leveling behavior, causing the platform to tilt unexpectedly or fail to stabilize on inclined or uneven surfaces. Such issues typically involve sensor malfunctions, hydraulic system leaks, or control system faults.
Common Causes and Diagnostics
The Genie S85 also features dual-speed wheel motors, positive traction drive, and a 12V DC auxiliary power system supporting consistent operation in various environments. The machine is equipped with safety alarms and features like auto engine fault shutdown, enhancing reliability.
Conclusion
Platform leveling issues in the 2012 Genie S85 can be traced to sensor, hydraulic, mechanical, or electrical system faults. A methodical inspection focusing on these areas is vital for restoring proper platform stability. Preventive maintenance, operator training, and adherence to manufacturer guidelines ensure ongoing safe and efficient operation of this high-reach telescopic boom lift.

Problems with platform leveling can manifest as uneven or unresponsive leveling behavior, causing the platform to tilt unexpectedly or fail to stabilize on inclined or uneven surfaces. Such issues typically involve sensor malfunctions, hydraulic system leaks, or control system faults.
Common Causes and Diagnostics
- Sensor Faults: Tilt sensors or inclinometer failures provide incorrect feedback to control units, disrupting stabilization commands.
- Hydraulic Leaks or Air Entrapment: Fluid loss or air bubbles in hydraulic circuits can reduce system responsiveness or cause jerky platform movements.
- Joystick or Controller Issues: Faulty controls may fail to send accurate input signals for leveling correction.
- Mechanical Binding or Damage: Physical obstruction or damage to boom joints or leveling actuators can impair smooth motion.
- Electrical Wiring Problems: Loose or corroded connections affect signal transmission to sensors or control modules.
- Conduct thorough inspection of tilt sensors and inclinometer calibrations; recalibrate or replace as necessary.
- Check hydraulic fluid levels and inspect hoses, fittings, and cylinders for leaks; bleed air from the system.
- Test joystick and control box functionality, replacing worn or defective components.
- Examine mechanical joints and actuators for signs of wear or binding, lubricating or repairing as needed.
- Review electrical wiring harnesses and connectors, ensuring integrity and proper grounding.
- Regular calibration of sensors and preventive inspection of hydraulic and electrical components help avoid unexpected level failures.
- Operators should familiarize themselves with alarm systems such as tilt and descent alarms included on Genie lifts.
- Training on safe operation under leveling failure conditions minimizes accident risks.
- Self-Leveling Platform: A platform that maintains horizontal position automatically via sensor and hydraulic feedback.
- Tilt Sensor/Inclinometer: Devices measuring the angle or inclination of the platform or boom.
- Hydraulic Bleeding: The process of removing entrapped air from hydraulic circuits to maintain system efficiency.
- Hall Effect Joystick: A joystick using magnetic sensors for precise, non-contact control inputs.
- Platform Rotation: Hydraulic capability to rotate the platform, increasing operational flexibility.
