Failure Symptoms

The first indication of a faulty seat adjustment valve is the inability to move the seat or the seat slowly drifting from its set position. If ignored, the adjustment mechanism may become completely inoperable, leaving the operator in an uncomfortable or unsafe driving position. The ultimate consequence is reduced operator comfort, increased fatigue, and potential strain injuries during long driving shifts.

Installation Tip

Ensure all air or hydraulic lines are correctly connected to the valve ports, paying close attention to any labeling or diagrams. Avoid forcing connections, as this can damage the valve's ports or the lines themselves.

Service Note

Inspect the pneumatic or hydraulic lines connected to the valve for leaks or damage, and check the seat suspension system for proper operation.
