KJ-1350 & KJ-1750 Jetter Machines
NOTE! If at any time during the jetting process the pres-
sure oscillates up and down between 100 and
1000 PSI, stop the jetter: Turn the Jetter and
water supply OFF, remove the jetter nozzle and
check the nozzle orifices (They are probably
blocked). Clean them with the nozzle cleaning
tool by pushing the proper size wire completely
through each thruster orifice.
If the problem persists, remove the nozzle and
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.
Once through the bend or trap, return the pulse control
actuator lever and valve to the OFF position. Continue
the jetter head's advance.

Encountering Blockages

Normally, the jetter nozzle will pass right through grease
or soft blockages. More stubborn blockages may require
manual manipulation of the hose combined with the pulse
action of the pump.
Once through the obstruction, pass the jetter nozzle
back and forth several times through that section of
the drain to ensure it is thoroughly cleared, then advance
the nozzle several feet further down the line before re-
trieving the hose.

"Jet-Cleaning" or "Jetting" the Line

The Jetter's cleaning action occurs by the nozzle orifices
directing high pressure water at the walls of the drain
line. This same pressure produces the thrust that pushes
the nozzle down the line. This cleaning action helps to re-
store the drain to the full inside line diameter. The slower
the jetter hose is retrieved, the better the results.
Before the jetter hose is retrieved back out of the drain,
turn the pulse dampener valve (#2) to the OFF position.
This will maximize the pressure and flow at the nozzle.
Slowly retrieve the jetter hose and clean the inside
walls of the drain.
WARNING Never permit end of hose to rotate out of
the pipe being cleaned. Hose can whip and nozzle spray
can penetrate skin causing serious injury.

Pressure Wash Package

Both the KJ-1350 and KJ-1750 can operate as pressure
washers to spray wash service vehicles, tools, drain
cleaning equipment and cables. The wash wand mounted
to the 1 / " x 35' hose is attached to the jetter outlet port.

Detergent can be dispensed for more effective cleaning by
using the injector manifold. Attach the supply hose to
10
the manifold and submerse the other end into a liquid so-
lution.

Washer Operation

WARNING
human.
To utilize the pressure wash feature make sure both
pulse valves are in the OFF position. Adjust system pres-
sure with the wash wand activated. The wash wand will fit
the 1 / " ID x 35' hose provided or any
4
The injector introduces a detergent into the water flow for
more effective cleaning. To use the injector:
1. Attach the injector to the outlet port by removing the
connection hose and quick coupling on the Jetter.
Use thread sealant to prevent any leaks. Make sure
arrow on manifold is going in the right direction (away
from Jetter).
2. Re-attach connection hose and attach wash wand
hose to quick coupling.
3. Place one end of a siphon hose into the detergent's
container and other end on injector manifold.
4. The wash wand has two adjustments on the nozzle.
By rotating the nozzle the wash pattern can be wide or
narrow. The nozzle can be pushed forward for low
pressure. Detergents are only dispensed when wash
wand nozzle is in the low pressure setting.
5. After the application, pull the nozzle back to achieve
full pressure.
