DANGER
Do not attempt to clean a manhole with the WGR hanging by the hose. The tool can turn around and
strike the Operator. Specific accessories are offered and are required to safely clean manholes. Do
not allow the tool to enter a manhole or vault while in operation. If the tool is not contained in a pipe it
presents a serious hazard and if not avoided could result in death or serious injury.
NOTE: A 15-25 foot long section of leader hose of a different color than the jetter hose is recommended
to indicate how close the tool is to exiting the pipe.
• Flush the jetter hose prior to installing the nozzle to remove debris. Install the hose guard or Tiger
Tail. If the WGR is being used in pipe diameters less than 10 inches it can be attached directly to
the hose end. If being used in larger pipes a straight rigid pipe or centralizer must be placed behind
the tool such that the rigid length is greater than the pipe diameter to ensure the tool cannot turn
around in the pipe.
• To clean lines, position the WGR and Tiger Tail so it can enter the pipe to be cleaned. The
recommended cleaning direction is upstream from the manhole.
• Slowly bring the pump up to pressure, making certain that the WGR begins to pull its way into the
pipe in the proper direction; allow it to advance a few feet and note the location of the leader hose
or other hose marker being used. Once the pump is up to operating pressure, feed out the reel at a
reasonable rate to allow the jets time to clean the pipe.
• If roots are present, feeding at a slower rate will improve the cleaning results. Depending on the
amount of debris in the pipe, it may be necessary to occasionally pull the WGR back toward the
manhole to prevent buildup of debris behind the tool.
• When finished cleaning, withdraw the tool back to its initial starting point noted by the location of
the leader or hose marker.
• Shut down and secure the pump before removing the WGR from the line.
• After the job has been completed, remove the WGR from the hose and blow out the water with
compressed air to prolong the life of the internal components.
