KJ-2200/KJ-3100 Water Jetting Machines
• 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.
Figure 15 – Rotating the Hose
Once past a blockage, take the time to clean that sec-
tion 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.
Watch the drain water level. If the water level gets too
high, you may need to turn the jetter OFF and allow
the water to drain prior to continuing. Jetting when the
line is full of water is less effective than when the line
is empty. Do not allow the jetter to run for extended
period of time with the foot valve OFF. When the foot
valve is OFF, water recirculates in the pump and cause
the water to heat up. This can cause the pump thermal
overload to open.

Once the nozzle is the desired distance into the drain,
slowly (1 ft / 30 cm per minute for heavy drain accu-
mulations) pull the nozzle back through the drain. Use
one hand to control the hose and the other to wind the
hose onto the reel. Watch as the nozzle gets closer to
the drain opening that the nozzle does not come out
of the drain while water is flowing. This could allow the
hose to whip around and cause striking and high pres-
sure fluid injuries. Always control the hose. Look for
the mark on the hose near the nozzle. Release the foot
valve to shut off the water flow.
Turn OFF the engine as directed in the engine manual,
and depress the foot valve to release the system pres-
sure. Never leave the system pressurized. If needed,
change the nozzle and continue cleaning following the
above process. Several passes through a line are rec-
ommended for complete cleaning.
When finished, with the jetter shut off, remove the noz-
zle and open inlet supply valve to flush out the pump
and hose. If using the jetter in cold weather conditions,
immediately drain the water from the system to help
prevent damage from freezing. See Machine Storage
for information on freeze protecting.
Using the Pulse Mode
When manipulating the hose is not enough to pass
through a direction change or obstruction, the pulse
mode should be used. The pulse mode induces large
variation in water pressure that causes the hose to vi-
brate, easing hose advancement.
1. Turn the pulse actuator lever clockwise to the "Pulse"
position. In pulse mode, the pressure gauge will read
less than full pressure. This is normal.
