WGR SWITCHER OPERATION AND TROUBLESHOOTING
OPERATION:
Install the WGR Switcher Nozzle onto the hose end. Position hose and nozzle into the pipe to be
cleaned. We recommend running the nozzle into the pipe about 3-5 feet. Verify switcher’s position of by
bringing the nozzle up to operating pressure.
Note:
1. While pressurizing the hose and nozzle expect a pressure jump when the switcher engages, which
should be below the operating pressure.
2. In the pulling/flushing mode there will be more tension on the hose versus the cleaning mode. Also
listen to the sound and watch the air/water flowing out of the pipe. Faster air/water flowing from the
pipe indicates the switcher is in the pulling/flushing mode. Slower air/water flowing from the pipe
indicates the switcher is in the cleaning mode. To switch modes, dump pressure from the hose and
nozzle until the pressure gauge reads zero. This may take several seconds. Then bring the hose and
nozzle back to operating pressure. Repeat these steps to switch between modes as necessary.

TROUBLE SHOOTING:
Tool Is Not Switching:
• If the Switcher appears to be “stuck” in either the pulling/flushing or cleaning mode, first cycle the
pump up and down in pressure several times.
• If cycling the tool doesn’t fix the problem, the Switcher Head will need to be removed from the
WGR Body and disassembled (refer to the disassembly/assembly page). The Switcher is designed
to handle debris up to .030 inches in diameter, but larger particles may lock up the mechanism.
Thoroughly clean all the components once disassembled. Examine components for excessive
wear or any other visible problems. Once cleaned and examined, the Switcher can be reassembled
following the procedure on the second page. If proper switching is not achieved with this procedure,
the Switcher will need to be returned to StoneAge for evaluation.
