Plan Your Gear Box and Pressure-Control Repair
Record the operating problem before selecting parts. Pressure changes, starting faults and unusual noise need diagnosis, as the affected component may be in the control, motor, drive or fluid system.
Check for a cracked or stripped knob. A knob replacement does not address every electrical pressure-control fault.
Have the potentiometer and associated control system assessed using the applicable service procedure.
Have the cause investigated before fitting a replacement. Match the specified fuse and never bypass circuit protection.
Stop operation and arrange inspection. Identify the correct mounting or drive component before replacing parts.
Service safety: Disconnect power, relieve system pressure and follow the Titan instructions before maintenance. Use a qualified technician for internal electrical testing and repairs.
