Signs a Platform Control Box May Need Replacement

• The platform lift or lower function operates intermittently.
• The joystick does not provide consistent drive response.
• The emergency stop button is physically damaged.
• Control switches are broken, loose or no longer responsive.
• The enclosure is cracked or has suffered impact damage.
• The cable, plug or connector is cut, worn or damaged.
• Water or contamination has entered the original control box.

Diagnose Before Replacing

Platform control problems are not always caused by the control box itself. Similar symptoms may result from low battery voltage, damaged wiring, loose connectors, relays, switches, hydraulic valves, machine controllers or safety interlocks.

Inspect and diagnose the machine before replacing the control unit. When possible, confirm the fault using the machine service information or a qualified equipment technician.
