KJ-2200 Water Jetter Machine
zle will advance the jetter hose, but it is also necessary
to manually feed and rotate the jetter hose to work the
set around the bend.
3. If the hose will not advance, pull back on the hose
slightly and rotate the hose a quarter to a half turn so
the set will align itself with the bend. Then advance the
hose forward.
Using The Pulse Mode To Negotiate
Bends And Traps
In some cases, simply rotating the hose will not be
enough to negotiate a bend or trap. In these instances, it
will be necessary to induce some pulse action. In the
pulse mode, the pump induces large pulsation and jetter
hose vibration which will ease hose advancement.
1. Rotate the pulse actuator lever clockwise to induce the
pulse (Figure 5).
2. While in the pulse mode, again rotate the hose to align
the set with the bend. This technique will normally
overcome stubborn bends and traps.
NOTE! In the pulse mode, the jetter's pressure gauge
will read approximately 1800 – 1900 PSI.

3. Once through the bend or trap, return the pulse con-
trol actuator lever to the OFF position. Continue the
jetter head's advance.
Encountering Blockages
1. If the jetter nozzle does not pass right through the
blockage, combine the pulse action of the pump with
manual manipulation of the hose.
2. Once through the obstruction, pass the jetter nozzle
back and forth several times (preferably with pulse
OFF) through that section of the drain to ensure thor-
ough clearing. Then advance the nozzle several feet
further down the line before retrieving the hose.
"Jet Cleaning" or "Jetting" the Line
The jetter's cleaning action occurs by the nozzle orifices di-
recting high pressure water at the walls of the drain line
restoring the drain to the full inside line diameter. (This
same pressure produces the thrust that pushes the nozzle
down the line.) The slower the jetter hose is retrieved, the
better the results.
1. Make sure the pulse actuator is OFF. This will maxi-
mize the pressure and flow at the nozzle.
2. Slowly retrieve the jetter hose and clean the inside
walls of the drain.
WARNING
the pipe being cleaned. Hose can whip and nozzle spray
can penetrate skin causing serious injury.
NOTE! If at any time during the jetting process the pres-
sure oscillates up and down between 100 and
2200 psi, stop the jetter:
• Turn the jetter and water supply OFF. Remove
• If the problem persists, remove the nozzle and
Pressure Wash Package
(Optional Accessory)
The KJ-2200 can operate as a pressure washer to spray
wash service vehicles, tools, drain cleaning equipment
and cables. The wash wand mounted to the
hose is attached to the jetter outlet port. Detergent can be
dispensed for more effective cleaning by using the in-
jector manifold.
To Utilize the Wash Feature
WARNING

1. Make sure the pulse actuator is in the OFF position.
2. Attach the wash wand to the

(They are probably blocked). Clean them with the

wire completely through each thruster orifice.
insert the hose into the drain. Check the inlet fil-
ter screen at the inlet port and make sure it is
clean. Restart to flush the system of any trapped
air or debris that could be hampering the unit's
operation.
