Setting up for Operation
Fig. 4
Always locate the jet in the driest and safest place possible. Avoid high traffic areas and use flashers and safety
cones. Position the jet so that hose can be pulled directly off of the reel for use. Remember that jetting is most
effective when you jet against the water flow. See Fig. 4 for the recommended positioning of the jet for best visibility
during manhole work. Note that loose hose and damaging corners are minimized when the jet is parked as shown.
(See pages 15 and 16 for instructions on using upper and lower manhole guides.)
When operating upon unlevel ground, position trailer with the hitch (tanksump) end at the downhill side.
Warning: Trailer must be level for low water shutdown to operate correctly. When trailer is on an incline
with hitch end at the down hill side and tank is empty, enough water can be held in the lower front corner
of tank to keep float switch in the operating position.
For non-manhole use, allow extra space for handling the hose before it is wound back on the reel or run the hose
directly to the pipe inlet using extra hose guards to protect the hose from cutting when going around corners.
Warning: Do not unhitch or operate trailer jet unhitched upon unlevel ground.
When unhitching the machine from towing vehicle, always follow these steps:
— Place wheel chocks around trailer jet wheels.
— Lower hitch jack, pin clamp securely.
— Disconnect ball hitch by raising lever and jacking hitch up. Disconnect safety chains and light cord before driving
away.
