Operating Instructions
WARNING
Always wear eye protection to protect your eyes
against dirt and other foreign objects. Always wear
appropriate personal protective equipment for the
work environment.
Never operate the jetter with the hose end outside
of the drain. Hose can whip, causing striking inju-
ries and spray can penetrate skin and cause serious
injury.
High pressure fluid can inject under skin resulting
in serious injury, including amputation. Do not di-
rect spray at people or animals.
Do not operate jetter above pressure rating or
140°F / 60°C (inlet water temperature). This increas-
es the risk of injury, including burns, and damage
to the jetter.
One person must control both the jetting process
and the foot valve. Always use the foot valve. If the
jetter hose comes out of the drain, the operator
must be able to shut the water flow off to reduce the
risk of the jetter hose whipping, causing striking
and high pressure injection injuries.
Always use appropriate personal protective equip-
ment while handling and using drain cleaning
equipment. Drain may contain chemicals, bacteria
and other substances that may be toxic, infectious,
cause burns or other issues. Appropriate person-
al protective equipment always includes safety
glasses and gloves, and may also include equip-
ment such as latex or rubber gloves, face shields,
goggles, protective clothing, respirators, and steel
toed footwear.
Follow operating instructions to reduce the risk of
injury from whipping hoses, high pressure liquid
injection, carbon monoxide and other causes.
1. Make sure that machine and work area is properly
set up and that the work area is free of bystanders
and other distractions. If the jetter is located remote-
ly from the point of use, another person should be
located at the jetter.
2. Insert the hose with nozzle attached into the drain
at least three feet so that the end of the hose will not
come out of the drain and whip around when the
machine is started.
3. Confirm that the pulse actuator lever is rotated
count er-clockwise in the “Pressure” position (Figure
16).
4. Open the inlet supply valve. Never start the engine
without the water supply turned ON. This can dam-
age the pump.
5. Press the foot valve to reduce pressure and allow
the engine to start. Confirm that water flows freely
through the nozzle. Following the starting instruc-
tions supplied in the engine manual, start the en-
gine. Allow the engine to warm up.

Features four (4) reverse jet thrusts for maximum propulsion to jet long distances. Use this nozzle
for most applications.
H-101 H-111
Uses three jet thrusters in reverse plus one jet pointed forward to penetrate solid grease or sludge
blockages. The forward jet blasts a small hole in the blockage for the nozzle to follow. It is also
very effective when jetting ice blockages.
H-102 H-112
Use the drop head to help negotiate difficult bends. This nozzle has four (4) reverse jet thrusts. H-104
Use the spinning nozzle to help clean grease and similar blockage from drain. H-105 H-115
Use to clear roots and other type of blockages.
NOTE! Use extension to stabilize the RR3000 when cleaning 8” / 200 mm diameter drains.
