Operation Instructions
1. Attach garden hose to water faucet. Check that flow
rate with your supply hose is at least 8 gal/minute.
Run water to clear air and flush debris out of faucet
and hose before connecting to pump.
Shut water off again when water runs clear.
2. Attach other end (male end) of garden hose to water
inlet valve at pump.
3. Connect jetter hose to reel.
4. Attach nozzle to end of hose. Finger tighten, do not
over tighten.
5. Mark the hose approximately 10ft back from nozzle
with electrical tape. Use this tape as your signal to shut
off machine before retrieving all the hose out of the
drain when you are finished.
6. Open water intake.
7. Open water faucet again
to prime pump. An equal
amount of water should
pass through the orifices of
the nozzle.
8. Push jetter hose into drain
up to the marker if possible,
or minimally 3 to 4 feet.
9. Start Motor/Engine
• Turn the fuel valve to the “open”
position
• Pull out the choke lever.
Do not use choke if engine is warm
or ambient air temperature is high.
• Make sure the throttle is approxi-
mately halfway between “MIN” and “MAX”
• Turn key to “start” and start engine
• Push choke lever in
• Move throttle to desired speed
10. Adjust pressure with pressure regulator knob, turning
right to increase pressure, left to decrease.
u
NOTE: For normal operation, do not exceed the
recommended 3000 psi with the 3/8” hose.
As the engine starts, the hose will start to advance down
the drain line. Pull the jet hose from the reel and guide it
into the line. After it advances a few feet, pull the hose back
1/2 way. The actual cleaning of the line takes place when
the hose is pulled back. Repeat the forward/back process.
Helpful Operating Hints
• Tight bends and certain blockages are often more
easily negotiated by rotating or twisting jetter hose at
drain opening. Form a loop of hose then rotate the loop
90° to 180° until the hose advances. If the hose still fails
to advance, switch to a smaller diameter hose
• Once you are through that area, pull back and pass
through several times to ensure cleaning.
• Any time you open a blockage(s), pull hose back very
slowly to provide maximum cleaning to wall of pipe.
• Use pulsation only if needed to promote forward motion
of nozzle and hose.
• When operating from the high end to low end (most
common) briefly shut off the water flow ball valve on the
reel occasionally. This will allow debris to get ahead of the
nozzle and flush it down the pipe. It is best to clean the
line several times to ensure all debris is removed
• Grease and Ice Blockages High-pressure water can
be used to clear an ice blockage. A 3,000 PSI gas jet can
clear a 4” line at an approximate rate of one foot per
minute depending on the ice blockage. Ambient air
temperature will affect these times. Use a nozzle with a
forward jet. Warm water is effective in cleaning grease
and ice blockages as well. A cold-hot mix from the tap is
adequate. However, do not exceed 145° F, it can damage
seals in your pump.
Pre Operation Checklist
• Be sure you understand all
safety precautions (pg 3)
and have been trained to
use the machine.
• Locate jetter on level
surface where water won’t
pool, engage brake
• Check fluid levels—
oil in pumps, oil and gas
in gas motor
• Check for adequate water
flow—supply hose should
deliver at least 8 gallons/
minute.
•
• Check hose for wear or
kinks, that all hoses
and lines are clear and that
inlet filter is clean
• Select nozzle and make
sure orifices are not blocked
or worn to excess.
•
• Check that hose reel and all
connections are tight
• Wear protective clothing:
gloves, rubber boots and
goggles or face shield to
protect your eyes from
spray.
Remote Jetting Set Up
• Do steps 1-5
• Position the pressure hose
and reel at the drain site.
• Connect the 50’ jumper
hose between jetter and
the inlet on the hose reel.
• Open the ball valve
on the reel.
• Continue from step #6
