Terex SmartPTO V3 Quick Start Guide

Terex quick start for the SmartPTO V3: dash-display PTO setup, starting the pump from cab or control panel, hybrid bucket controls, and charging.


  • At the SmartPTO Main Control Panel, ensure the Emergency Stop pushbutton is reset. To reset the Emergency Stop, TWIST clockwise and PULL outward to allow the pushbutton to return to the OUT (reset) position.

Note: If the Emergency Stop is active, the dash-mounted display will indicate the SmartPTO is “NOT DETECTED”.

  • Turn off the vehicle ignition and allow the engine to stop running. After the engine has shut down, turn the ignition key forward to the ON position, without starting the engine. This powers accessory equipment (strobes, work lights, etc.)

  • Prior to leaving the cab, turn ON the truck PTO system by pressing the PTO button on the dash-mounted display. The SmartPTO status should switch from “DETECTED” to “ALLOWED”.

  • When you are ready to use the vehicle hydraulic systems, the SmartPTO pump can be started EITHER from the cab or from the exterior SmartPTO Main Control Panel.
    • To start the SmartPTO pump from the truck cab, press the E-PTO button on the dash-mounted display, which will toggle from off to Green.
    • To start the pump from the SmartPTO Main Control Panel, PRESS and HOLD the Pump Toggle switch for 2 seconds to activate the SmartPTO hydraulic pump.

  • When the hydraulic pump is activated, the Touch Encoder display will switch to the “Pump Status” screen (below), which shows operational status of the unit. Verify the Pump GPM and the Pump Pressure on the Touch Encoder display.

  • Utilize the vehicle’s hydraulic systems per the normal operational procedures, for example:
    • Deploy the vehicle outriggers
    • Switch to upper controls
    • Operate the overhead boom or winch
    • Use hydraulic tool attachments

Efficiency Tip: When the chassis hydraulics are in “outrigger mode”, switch modes or turn OFF the SmartPTO pump as promptly as possible when work is completed to prevent wasting available SmartPTO energy.

  • Turn Recirculation on, then press the “eAC” button to enable the electric AC compressor.
Charging the SmartPTO

Standard Charging (Level 1)

  • Plug a 15 Amp rated, 120V extension cord into the charging port. The SmartPTO LEDs turn ON to indicate charging.

⚠️ WARNING! Using an improperly rated electrical cord could cause the cord to heat up, melt, or start a fire.

Optional Fast Charging (Level 2)

  • Plug into the SmartPTO J1772 EVSE (Level 2) charging port using a properly rated J1772 Charging Connector.
  • Press and HOLD the Fast Charge “Start” button to initiate the charge session.
  • Verify the unit is charging by checking the Touch Encoder Display or by monitoring the LED Array.
