Setup and Installation

Follow these steps carefully to replace the rear handle assembly on your Stihl hedge trimmer. If you are unsure about any step, consult a qualified service technician.

1. Prepare the Trimmer:
   • Ensure the hedge trimmer engine is completely cool.
   • Disconnect the spark plug cap from the spark plug to prevent accidental ignition.
   • Place the trimmer on a stable, flat surface.
2. Remove the Old Handle Assembly:
   • Locate the screws or fasteners securing the existing rear handle assembly to the trimmer body. Carefully remove them.
   • Gently detach the old handle, paying attention to how the throttle cable and ignition wires are routed and connected.
   • Disconnect the throttle cable and ignition wires from their respective points on the trimmer. Note their exact connection points for reassembly.
3. Install the New Handle Assembly:
   • Carefully route the new throttle cable and ignition wires from the SENRISE handle assembly to their corresponding connection points on the trimmer.
   • Connect the throttle cable securely.
   • Connect the ignition wires to their correct terminals. Ensure connections are firm and insulated.
   • Position the new handle assembly onto the trimmer body, aligning it with the mounting holes.
4. Secure the New Handle:
   • Insert and tighten the screws or fasteners that secure the new handle assembly to the trimmer body. Do not overtighten, as this can strip threads or crack plastic.
   • Ensure the handle is firmly attached and does not wobble.
5. Final Checks:
   • Visually inspect all connections to ensure they are correct and secure.
   • Verify that the throttle lever moves freely and returns to its idle position.
   • Ensure the ignition switch operates smoothly.
   • Reconnect the spark plug cap.
