Jetting The Drain - Rigid KJ-2200 Manual De Instrucciones

KJ-2200/KJ-3100 Water Jetting Machines
• Inspect system for leaks. Use caution during in-
spection to prevent injury. If leaks are found, shut
jetter OFF before fixing.
• Turn the jetter OFF. Check the inlet filter/filter
washer and make sure that they clear of debris.
• Make sure there is adequate water flow to the
jetter.
• Turn the jetter and inlet supply valve OFF. Re -
move the nozzle and clean the orifices with the
nozzle cleaning tool.
• Run the jetter without a nozzle on the hose to re-
move air or debris from the system. Turn the jetter
OFF before removing or attaching the nozzle.
7. Assume a proper operating position.
• Be sure you can control the ON/OFF action of
the foot valve. Do not press the foot valve yet.
• Be sure that you have good balance and do not
have to overreach.
• You must be able to place one hand on the jetter
hose at all times to control and support the hose.
• You must be able to reach the reel for coiling the
hose.
This operating position will help to maintain control
of the jetter hose.

Jetting the Drain

When jetting a drain, typically the hose is fed into the
drain the full distance to be cleaned and slowly pulled
back. This allows the high pressure water directed at the
drain walls to remove build-up.

Release the locking pin on the hose reel. With at least
three feet of hose in the drain and one hand on the hose
to control its movement, depress the foot valve. The re-
verse jet thrusters on the nozzle will help pull the hose into
the drain. Feed the hose in the as far as needs to be
cleaned. If the hose stops, it has encountered some type
of obstruction.
If the nozzle cannot pass through an obstruction, such as
a change in direction (trap, turn, etc.) or a blockage.
Figure 15 – Rotating the Hose.
Once past a blockage, take the time to clean that section
of drain prior to moving forward. Move several feet past
the area of the obstruction and slowly pull the nozzle
back through the area of the obstruction. Do this several
times and then move further into the drain.

• Use sharp thrusts of the hose
• Rotate the hose a quarter to half turn to orient the
set of the hose to the direction change (If the
hose is rotated, once through the obstruction,
turn the hose back to help prevent kinks) See
Figure 15.
• Use the pulse mode.
• Use a trap hose or smaller diameter hose.
