side of the drain. Hose can whip, causing striking
injuries and spray can penetrate skin and cause serious
injury.
• High pressure water can inject under skin result-
ing in serious injury including amputation. Do
not direct spray at people or animals.
• Do not operate jetter above pressure rating or
140°F (inlet water temperature). This increases the
KJ-2200/KJ-3100 Water Jetting Machines
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 personal protective equipment always includes safety glasses and gloves, and

Description, Specifications and
Standard Equipment
Description
The RIDGID®Engine Powered Water Jetting Machines are
portable high pressure water jetters designed to use a
combination of water pressure and flow to clear grease,
sludge, sediment and roots out of drains. A highly flexible
and lightweight hose is propelled through the drain by
the reverse jets on the jetter nozzle, and when retrieved
scrubs the line flushing debris away. With the pulse activation engaged, difficult bends and traps are more easily
negotiated. All machines are equipped with a gasoline engine to drive the triplex plunger pump.

can restrict the water flow to the pump and cause performance issues.
Figure 7 – Inlet Filter/Filter Washer
5. Inspect the jetter nozzle orifices for any damage or
blockage. Blockages can be cleaned with a nozzle
cleaning tool. Use care not to enlarge nozzle orifices
while cleaning. Damaged nozzles or nozzles with
enlarged orifices can decrease jetter performance
and should be replaced.
6. Inspect the hoses, connectors and fittings for wear and
damage. If there are any kinks, cracks, breaks or
wear through the outer jacket of the hose or other
damage, do not use the hose. Damaged hoses can
burst or leak high pressure water and cause serious
injury. Replacement hoses and fitting should be rated
at or higher than the jetter pressure.
7. Inspect and maintain the engine per the engine operator’s manual.

1. Check work area for:
• Adequate lighting.
• Flammable liquids, vapors or dust that may ignite. If
present, do not work in area until sources have
been identified and corrected. The jetter is not explosion proof and can cause sparks.
• Clear, level, stable dry place for machine and operator. If needed, remove the water from the work
area. Wood or other coverings may need to be put
down.
• Jetter location that is in a well ventilated outdoor
area. Do not place the jetter indoors, even with
doors and windows open. Jetter can be located remotely from the point of use.
• Suitable water supply.
• Clear path to transport the jetter to the set up location.
2. Inspect the drain to be cleaned. If possible, determine
the access point(s) to the drain, the size(s) and
length(s) of the drain, distance to tanks or mainlines,
the nature of the blockage, presence of drain cleaning
chemicals or other chemicals, etc. If chemicals are
present in the drain, it is important to understand the
specific safety measures required to work around
those chemicals. Contact the chemical manufacturer
for required information.
If needed, remove fixture (water closet, etc.) to allow ac-
cess to the drain. Do not feed the hose through a fixture. This could damage the hose and the fixture.
3. Determine the correct equipment for the application.
See the
Specifications
section for information on these
jetters. Drain cleaners and jetters for other applications
can be found by consulting the RIDGID Catalog, on
4. Make sure all equipment has been properly inspected.
5. Evaluate the work area and determine if any barriers
are needed to keep bystanders away. Bystanders
can distract the operator. If working near traffic,
erect cones or other barriers to alert drivers.
6. If needed, place protective covers in the work area.
The drain cleaning process can be messy.
7. Take the jetter to the well-ventilated outdoor work
area along the clear path. If the machine needs to be
lifted, use proper lifting techniques. Use care moving
equipment up and down stairs, and be aware of possible slip hazards. Wear appropriate footwear to help
prevent slips.
Water Supply
Confirm that there is sufficient water flow for jetter. Run a
hose from the water source to the jetter. Use the largest diameter, shortest length hose possible. A
3
/4" I.D. hose is the
minimum recommended size. An appropriate backflow
prevention device should be used to comply with all local
codes and ordinances. Turn the water on at the source and
measure the time it takes to fill a clean five gallon bucket.
See the following table for maximum bucket fill times for
each jetter.
Insufficient water flow will prevent the jetter from reaching
the pressure rating and could damage the pump. Inspect
the water in the bucket for dirt and debris. Dirt and debris in
the water supply can cause excess pump wear, clog the jetter filters nozzles and reduce performance. Do not use
water from ponds, lakes or other sources that may be
contaminated.
In cases of insufficient water flow, possible solutions include
using fittings to allow multiple supply hoses to be connected to the jetter or the use of a tank.
If a tank is used, plumb a tee with full port valves to the jetter water inlet as shown in
Figure 9.
Connect a 3/4" (19 mm)
hose no longer than 6 feet (1.8 m) to the valve on the outlet of the tee, and connect the water supply to the run of the
tee. Either place the hose end in the tank or connect to the
tank outlet. The entire length of the tank hose should be no
more than 5" (12.7 cm) above the jetter water inlet, or
the jetter will not draw water from the tank.

Fill the tank prior to starting the jetter. When starting jetter,
turn the tank valve OFF. As soon as the jetter is started,
open the tank valve. Monitor the tank water level, and if
needed, stop jetting to allow the tank to refill. Do not allow
the water level to fall below the hose end.
Hot water can be used for improved cleaning. Do not
use water hotter than 140°F. – this can cause the pump
thermal overload to open. When using hot water, use
appropriate personal protective equipment to reduce the
risk of burns.
When using in cold weather, use precautions to prevent
water from freezing in the pump. This can damage the
pump.
Make sure that the inlet supply valve on the jetter is
closed and attach the supply hose to the jetter.
Drain Preparation
If working through a manhole, storm grate or other large access, use pipe and fittings to create a guide for the jetter
hose from the drain opening to operation point. This will prevent the jetter hose from whipping around in the access and
protect the hose from damage.
Figure 10 – Extending the Drain Opening to the
Operation Point
Hose Set-Up
Use care when routing jetter hoses. Routing hoses over
rough surfaces, sharp edges, crossing hoses, etc. can
damage the hose jacket, especially when the jetter is used
in the pulse mode. Keeping the jetter hose on the reel
will help to minimize hose damage.
KJ-2200/KJ-3100 Water Jetting Machines
1. Select a jetter hose size appropriate for the drain
being cleaned. It is not generally recommended to
connect two jetter hoses together for cleaning drains.
The connection between the two hoses is less flexible
and can prevent passage through fittings
See Jetter
Hose Selection Chart.
2. As needed, separate the hose reel from the mot or/pump assembly. Locate the hose reel within 3 feet
of the drain opening. Do not allow excessive amounts
of hose outside of the drain to prevent hose damage. If the hose reel cannot be placed within 3 feet of
the drain opening, extend the drain opening back to
the hose reel with similar sized pipe and fittings.
3. Route a hose from the jetter to the IN fitting on the foot
valve. Use PTFE tape to seal the connection. Position
the foot valve for accessibility. You must be able to
control the jetter hose and the foot valve.
4. Connect the hose from the reel to the OUT fitting
on the foot valve.
Figure 11 – Foot Valve Connection
5. Mark the jetter hose near the end to indicate when the
nozzle is getting close to the drain opening when
withdrawn. This will help prevent the nozzle from
coming out of the drain and whipping around. The distance depends on the configuration of the drain, but
should be at least 4'/1.2 m.
6. Remove the nozzle from the end of the jetter hose
and place the end of the jetter hose in the drain.
Open the inlet supply valve to purge the air and any
debris from the jetter and hoses. Allow water to flow
for at least 2 minutes.
7. Close the inlet supply valve.
8. Select a nozzle. Use nozzles specifically sized for the
jetter being used. Using incorrect nozzles can cause
poor performance (low operating pressure or low
flow) or may damage the jetter with excessively high

pressures. Make sure the nozzle orifices are clear and
open.
See Jetter Nozzle Selection Chart.
If using the RR3000 nozzle for drains larger than 6"
and up to 9"/ 229 mm, the extension must be used.
For drains 6"/ 152 mm and smaller, no extension is
needed. If needed, firmly hand tighten the extension
to the RR3000 – do not over tighten. Using the
RR3000 nozzle in a line larger than 6" and up to 9"
without an extension, or in lines larger than 9" may
allow the nozzle to change direction in the drain, exit
at the user and cause serious injury
(Figure 12)
.
9. Firmly hand tighten the nozzle to the end of the hose
– do not over tighten. Over tightening the nozzle can
damage the nozzle and cause poor performance.
10. Insert the hose with nozzle attached into the drain and
open the inlet supply valve. Confirm that water flows
freely through the nozzle and close the inlet supply
valve.

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 injuries
and spray can penetrate skin and cause serious injury.
High pressure fluid can inject under skin resulting in
serious injury, including amputation. Do not direct
spray at people or animals.
Do not operate jetter above pressure rating or 140°F
(inlet water temperature). This increases 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 equipment 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 personal
protective equipment always includes safety glasses
and gloves, and may also include equipment 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 remotely
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 damage
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 instructions supplied
in the engine manual, start the engine. Allow the engine to warm up.
Figure 13 – Controls
6. Turn the unloader valve while monitoring the pressure
gauge to adjust the pressure as desired (clockwise to
increase pressure, counter-clockwise to decrease
pressure). Do not exceed the machine pressure rating being used. Do not force the unloader valve or use
wrench es or tools to turn. This will damage the unloader valve.
If the jetter will not generate the rated pressure or is er-
ratic
• Make sure the engine throttle is properly adjusted.
• Make sure that the inlet supply valve is fully open
and other valves in the supply system are fully
open.
• Turn unloader valve clockwise to increase pres-
sure. Do not force.
• Make sure the pulse actuator is on the “Pressure”
setting.
• Cycle the pulse actuator between the “Pressure”
and “Pulse” position several times while the unit is
running to clear any trapped air from the system.

• Inspect system for leaks. Use caution during inspection to prevent injury. If leaks are found, shut
jetter OFF before fixing.
• Turn the jetter OFF. Check the inlet filter/filter
washer and make sure that they clear of debris.
• Make sure there is adequate water flow to the
jetter.
• Turn the jetter and inlet supply valve OFF. Re move the nozzle and clean the orifices with the
nozzle cleaning tool.
• Run the jetter without a nozzle on the hose to remove air or debris from the system. Turn the jetter
OFF before removing or attaching the nozzle.
7. Assume a proper operating position.
• Be sure you can control the ON/OFF action of
the foot valve. Do not press the foot valve yet.
• Be sure that you have good balance and do not
have to overreach.
• You must be able to place one hand on the jetter
hose at all times to control and support the hose.
• You must be able to reach the reel for coiling the
hose.
This operating position will help to maintain control
of the jetter hose.
Figure 14 – Proper Operating Position
Jetting the Drain
When jetting a drain, typically the hose is fed into the
drain the full distance to be cleaned and slowly pulled
back. This allows the high pressure water directed at the
drain walls to remove build-up.
Release the locking pin on the hose reel. With at least
three feet of hose in the drain and one hand on the hose
to control its movement, depress the foot valve. The reverse jet thrusters on the nozzle will help pull the hose into
the drain. Feed the hose in the as far as needs to be
cleaned. If the hose stops, it has encountered some type
of obstruction.
If the nozzle cannot pass through an obstruction, such as
a change in direction (trap, turn, etc.) or a blockage.
• 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.
(see next section)
• Use a trap hose or smaller diameter hose.
Figure 15 – Rotating the Hose.
Once past a blockage, take the time to clean that section
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.

KJ-2200/KJ-3100 Water Jetting Machines
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 /minute for heavy drain accumulations) 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 pressure 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 pressure.
Never leave the system pressurized. If needed, change
the nozzle and continue cleaning following the above
process. Several passes through a line are recommended
for complete cleaning.
When finished, with the jetter shut off, remove the nozzle
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 infor-
mation 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 vibrate, 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.
Figure 16 – Pulse Actuator Lever Position
2. If needed, use sharp thrusts of the hose and hose rotation to help the nozzle through the obstruction.
3. Once through the obstruction, turn the pulse actuator
lever counter-clockwise to the “Pressure” position.
Do not leave the jetter in pulse mode any longer
than needed to pass through an obstruction. Exces sive use of the pulse feature can cause premature
wear on hoses and system.
Using Water Jetter Machine as a
Pressure Washer
The RIDGID water jetting machines can also be used as
pressure washers with the addition of the pressure wash
package. Use as a pressure washer is similar to use as a
jetter, and those instructions should be used in conjunction
with the following.
1. Locate an appropriate work area.
2. Make sure all equipment has been properly inspected.
3. Attach the wash wand to the wash wand hose. Al ways use hose with a pressure rating at least as
high as the jetter pressure rating. Use a thread sealant
to prevent leaks.
4. Attach hose to the jetter outlet. Make sure the ends of
the hose are securely connected to prevent them
from coming off under pressure.
5. Connect an appropriate water supply, as discussed
earlier, to the jetter.
6. Open the inlet supply valve and squeeze the wash
wand trigger to allow water to flow and purge any air
from the system. Never start the engine without the
water supply turned ON. This can damage the pump.

7. Make sure that pulse actuator lever is rotated counterclockwise in the “Pressure” position.
8. Wash Wand Nozzle Adjustments – By rotating the
nozzle, the wash pattern can be adjusted from a fine
stream to a wide fan type spray. By pulling the nozzle
forward (low pressure) and backward (high pressure), the pressure can be adjusted. Make sure that
the nozzle is pulled back to the high pressure position
to start operation.
Figure 17 – Wash Wand Nozzle Adjustments
9. Wash Wand Lock Out – the wash wand includes a
lock out on the back of the trigger. Flip the lock out
down to prevent the operation of the trigger when the
wash wand is not in use.
10. With the wand pointed in a safe direction, squeeze the
wash wand trigger to reduce pressure and allow the
engine to be started. Following the starting instructions
supplied in the engine manual, start the engine. Allow
the engine to warm up. Release the trigger as soon as
the engine starts.
11. With the wand pointed in a safe direction, squeeze the
wash wand trigger. Turn the unloader valve while
monitoring the pressure gauge to adjust the pressure as desired. Do not exceed the machine pressure
rating. Release the wash wand trigger.
Pressure Washer Operation
1. When using as a pressure washer use both hands to
grip and direct the wash wand for greater control.
Never direct the wash wand at people. High pressure
fluid can inject under skin resulting in serious injury.
Never direct wash wand at electrical equipment or
wiring to reduce the risk of electrical shock.
2. Control the flow of water with the trigger. Use care
when using the pressure washer. Holding the nozzle
too close to a surface can damage it. Test a small, inconspicuous area to confirm the settings work as
desired.
3. Do not allow the jetter to run for extended period of
time with the trigger OFF. When the trigger is OFF,
water recirculates in the pump and it causes the
water to heat up. This can cause the pump thermal
overload to open.
4. Once pressure washing is complete, release the trigger and turn OFF the engine as directed in the engine
manual. Squeeze the trigger to release system pressure. Never leave the system pressurized.
Detergent Injector
1. If needed, attach the detergent injector to the outlet
port. Remove the output hose and attach the detergent injector with arrow on the unit pointing the same
direction as the water flow. Use thread sealant to
prevent leaks. Reattach the output hose.
2. Attach the siphon hose to the detergent injector.
Place the strainer end of hose into the detergent
container. Only use detergents designed for use with
pressure washers. Follow all detergent instructions.
Do not spray flammable liquids or toxic chemicals.
Other detergents, solvents, cleaners, etc. can damage
the jetter, or cause serious injury.
3. When pressure washing, detergents are only dispensed when wash wand nozzle is in the low pressure position. Pull the nozzle forward to the low
pressure position to dispense detergent.
4. During operation, the detergent application rate can be
adjusted by turning the sleeve on the detergent injector. Counter-clockwise increases the amount of
detergent, clockwise decreases.
5. When detergent application is complete, remove the
strainer from the detergent, place into a bucket of
clean water and flush the system of any detergent.
Maintenance Instructions
WARNING
Before performing any maintenance, engine switch
should be in OFF position and spark plug wires
should be disconnected to prevent inadvertent operation. Press foot valve or wand trigger to release
any fluid pressure in system.
Always wear safety glasses and gloves when performing any maintenance to help protect against
drain chemicals and bacteria.
Cleaning
The hose should be cleaned as needed with hot, soapy
water and/or disinfectants. Do not allow water to enter
the engine or electrical system. Do not clean with pressure washer. Wipe the unit down with a damp cloth.

Engine
Maintain the engine as directed in the engine operator’s
manual supplied with the unit.
Pump Lubrication
Check the pump oil level prior to use. Place the jetter on
a level surface. Wipe any dirt and debris from the area
of the dipstick and remove the dipstick – check the oil
level. If needed, add SAE 30W non-detergent oil. Do not
overfill. Reinstall dipstick.
Change oil in pump after first 50 hours of operation
and every 500 hours of operation after that. With the
pump warm from operation, remove plug on bottom of
pump and drain oil into suitable container. Replace
plug. Fill with approximately 32 oz of SAE 30W non-detergent oil using the checking procedure.
Gearbox Lubrication
Check the gearbox oil level prior to use. Place the jetter
on a level surface. Wipe any dirt and debris from the
area of the dipstick and remove the dipstick – check the
oil level. If needed, add SAE 90W gear lubricant. Do not
overfill. Reinstall dipstick.
Change oil in gearbox every 500 hours of operation.
With the gearbox warm from operation, remove plug on
bottom of gearbox and drain oil into suitable container.
Replace plug. Fill with approximately 8 oz of SAE 90W
gear lubricant oil using the checking procedure.
Preparing Pump for Cold Weather
Storage
If the jetter will be stored under conditions
where the temperature is near or below 32°F (0°C),
the jetter must be properly prepared. If water freezes in
the pump, it can damage it.
There are two methods for preparing the jetter for cold
weather storage. The first is to open all valves in the system and use compressed air to force any water out of
the system. This can also be used to remove water
from the hoses.
The second method uses RV antifreeze (non-ethylene
glycol antifreeze). Do not use ethylene glycol antifreeze
in the jetter pump. Ethylene glycol cannot be used in
drainage systems.
1. Attach a 3 foot section of hose to the inlet supply
valve and open valve.
2. Place the end of the hose into the container of RV antifreeze.
3. Remove the nozzle from the end of the hose.
4. Start the jetter and run until antifreeze comes out of
the end of the hose.
