Why Does My Raymond EASI Have No Auxiliary Function and How Can I Fix It?

A Raymond EASI forklift showing no auxiliary (aux) function typically indicates issues with the mast controls such as reach, tilt, or side shift not responding. Troubleshooting involves checking joystick switches, mast cable integrity, driver cards, wiring, and hydraulic components to restore full aux functionality.

What Does “No Aux Function” Mean on a Raymond EASI Forklift?

“No aux function” means that while steering might work, auxiliary hydraulic functions like reach, tilt, and side shift do not activate. This limits the forklift’s ability to manipulate loads effectively and safely.

How Do You Diagnose Loss of Auxiliary Functions?

• Inspect joystick switches for proper operation and continuity.

• Check the mast cable for damage or disconnections.

• Swap or test driver cards controlling aux functions.

• Examine wiring harnesses and connectors for faults.

• Verify hydraulic pressure and solenoid valve function.

Systematic checks help isolate electrical or hydraulic faults.

Which Components Are Most Commonly Responsible for Aux Function Failures?

• Joystick switches: Faulty or worn switches can fail to send control signals.

• Mast cable: Physical damage or wear interrupts signal transmission.

• Driver cards: Malfunctioning cards fail to process commands.

• Hydraulic solenoids: Electrical or mechanical failure prevents actuation.

• Wiring and connectors: Corrosion or loose connections cause intermittent faults.

Why Is It Important to Check Both Electrical and Hydraulic Systems?

Auxiliary functions rely on both electrical signals and hydraulic power. Electrical faults prevent command signals from reaching valves, while hydraulic issues stop fluid flow even if signals are correct. Both systems must be operational for aux functions to work.

How Can You Test Joystick Switches and Mast Cables?

• Use a multimeter to test switch continuity in different positions.

• Visually inspect mast cables for fraying, breaks, or pinched sections.

• Swap known-good components to confirm faults.

• Monitor signal voltages at connectors during joystick operation.

When Should You Replace Driver Cards or Hydraulic Components?

• Replace driver cards if testing reveals no output despite correct inputs.

• Replace solenoid valves or hydraulic cylinders if mechanical failure or leaks are detected.

• Consider replacements if faults persist after wiring and switch repairs.

Where Can You Find Official Raymond EASI Service Manuals?

Authorized Raymond dealers provide detailed service manuals containing:

• Wiring diagrams and pinouts.

• Diagnostic procedures for aux function faults.

• Hydraulic schematics and valve specifications.

• Recommended test equipment and safety guidelines.

Consult manuals for accurate troubleshooting.
