The water may contain foreign objects such as sand, rocks, and other impurities, which can damage the rotor. To avoid these problems, you may need to install a filter. Troubleshooting non-rotation after installation: Check for plugged secondary nozzle and a blocked propeller in the turbine assembly.
- Remove the center plug with a flat blade screwdriver and unscrew the nut underneath using a 1/2" (13 mm) socket.
- Use the gear-drive insertion/ removal tool to unscrew the rotor from the piston. The tool will grab onto the screws below the rotor.
- Turn the wrench counterclockwise until the unit is free from the threads.
- Lift the unit out of the body.
- Remove the eight screws on the turbine housing (six large, two small).
- Pull to remove the propeller cover and expose the propeller.
- Remove the propeller from the housing to clear any debris that may be trapped inside.
- Turn the brass knob clockwise to slow down the rotation.
- Unthread the secondary nozzle.
- Clear any debris that may be trapped inside.
The rotating nozzle turret on the rotor has a ratcheting feature that allows the nozzle to be rotated to the field of play.
- Pull up the logo cap or activate the rotor to expose the nozzle turret and forcefully push the nozzle as needed.
- The nozzle turret will ratchet unless the arc adjustment clips interfere with the reversing trip arm on the back of the gear drive.
- If necessary, slide the arc adjusting clips to move the turret. The arc adjustment clips are used to adjust the arc in a similar fashion to impact-type sprinklers.
- To adjust the arc, activate the rotor and adjust the arc adjustment clips to set the arc to the intended area to be irrigated.
- The trip arm on the back of the gear drive can be moved manually to speed up the process.
