FOR FUTURE REFERENCE! Keep this manual with the machine for use by the operator.

• Never operate the jetter with the hose end out- 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 jet- ter.

• 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 equip- ment. Drain may contain chemicals, bacteria and other substances that may be toxic, infectious, cause burns or other issues. Appropriate personal protective equip- ment always includes safety glasses and gloves, and may also include equipment such as latex or rubber gloves, face shields, goggles, protective clothing, res- pirators, and steel toed footwear.

• Practice good hygiene. Use hot soapy water to wash hands and other body parts exposed to drain contents after handling or using drain cleaning equipment. Do not eat or smoke while operating or handling drain cleaning equipment. This will help pre- vent contamination with toxic or infectious material.

• Do not spray toxic or flammable liquids. This will re- duce the risk of burns, fire, explosion or other injury.

• Gasoline and its vapors are highly flammable and explosive. See engine manual for precautions to re- duce the risk of burns, explosions and serious injury while handling and using gasoline.

• Engines produce carbon monoxide, a colorless, odorless poison gas. Breathing carbon monoxide can cause nausea, fainting or death. Do not start and run engine in an enclosed area, even if doors and windows are open. Only operate outside.

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 acti- vation engaged, difficult bends and traps are more easily negotiated. All machines are equipped with a gasoline en- gine to drive the triplex plunger pump.

If prop- erly used it will not damage a drain that is in good con- dition and properly designed, constructed and maintained. If the drain is in poor condition or not prop- erly designed, constructed or maintained, the drain cleaning process may not be effective or could cause damage to the drain. The best way to determine the con- dition of a drain before cleaning is through visual in- spection with a camera. Improper use of this jetting machine can damage the jetter and the drain. This ma- chine may not clear all blockages. Machine Assembly WARNING To prevent serious injury during use and prevent machine damage, follow these procedures for proper assembly. Engine Oil Jetter is shipped without oil in the engine. Operating the engine without oil will result in engine failure. Add oil prior to operation. See supplied engine operator’s manual for specific information on adding oil and oil selection. Pump/Gearbox Oil Pump: Replace the plug in the top of the pump and re- place with dipstick/breather cap. Operating the jetter with the plug in place could damage the pump seals. Check oil level per Maintenance Instruction section. Gearbox (KJ-3100 only): Replace the plug in the top of the pump with dipstick/breather cap. Oper ating the jetter with the plug in place could damage the gearbox seals. Check lubricant level per the Maintenance Instruction section. Figure 4 – Assembly of the KJ-2200 KJ-2200 Transport Cart

4. Clean water inlet filter/filter washer.Unscrew cover

from bottom of inlet filter for cleaning. Dirt and debris can restrict the water flow to the pump and cause per- formance 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.

nect the hose reel latch and rotate the hose reel for- ward until it rests on the frame to provide access to the engine gas cap Figure 8 . If needed, add unleaded KJ-2200/KJ-3100 Water Jetting Machines FilterFuel Tank Cap8

1. Check work area for:

• 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 ex- plosion proof and can cause sparks.

• Clear, level, stable dry place for machine and oper- ator. 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 re- motely from the point of use.

• Suitable water supply.

• Clear path to transport the jetter to the set up loca- tion.

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 fix- ture. 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 line at www.RIDGID.com or www.RIDGID.eu

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 pos- sible 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 di- ameter, shortest length hose possible. A

" 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 jet- ter 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 con- nected to the jetter or the use of a tank. If a tank is used, plumb a tee with full port valves to the jet- ter water inlet as shown in Figure 9. Connect a

" (19 mm) hose no longer than 6 feet (1.8 m) to the valve on the out- let 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. Figure 9 – Water Supply Connections When Using A Tank KJ-2200/KJ-3100 Water Jetting Machines Jetter GPM Rating Maximum 5 Gallon Bucket Fill Time KJ-2200 2.4 125 seconds KJ-3100 5.5 55 seconds Hose To Tank Water In To JetterWater Supply In Tee Inlet FilterFull Port Valve9 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 ac- cess, use pipe and fittings to create a guide for the jetter hose from the drain opening to operation point. This will pre- vent 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 dam- age. 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 dis- tance 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 In Fitting Out Fitting10 KJ-2200/KJ-3100 Water Jetting Machines 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. Figure 12 – RR3000 Nozzle with Extension

Always wearappropriate personal protective equipment for thework environment.Never operate the jetter with the hose end outside ofthe drain. Hose can whip, causing striking injuriesand spray can penetrate skin and cause serious in-jury. High pressure fluid can inject under skin resulting inserious injury, including amputation. Do not directspray at people or animals.Do not operate jetter above pressure rating or 140°F(inlet water temperature). This increases the risk ofinjury, including burns, and damage to the jetter.One person must control both the jetting processand the foot valve. Always use the foot valve. Ifthe jetter hose comes out of the drain, the operatormust be able to shut the water flow off to reduce therisk of the jetter hose whipping, causing strikingand high pressure injection injuries.Always use appropriate personal protective equip-ment while handling and using drain cleaning equip-ment. Drain may contain chemicals, bacteria andother substances that may be toxic, infectious,cause burns or other issues. Appropriate personalprotective equipment always includes safety glassesand gloves, and may also include equipment such aslatex or rubber gloves, face shields, goggles, pro-tective clothing, respirators, and steel toed footwear.Follow operating instructions to reduce the risk ofinjury from whipping hoses, high pressure liquid in-jection, 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 lo- cated 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 -

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 en- gine 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 rat- ing being used. Do not force the unloader valve or use wrench es or tools to turn. This will damage the un- loader 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 in- spection 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 re- move 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 re- verse 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.13 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 noz- zle 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, im- mediately 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 ro-

tation 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. PULSEPRESSURE14 KJ-2200/KJ-3100 Water Jetting Machines

7. Make sure that pulse actuator lever is rotated counter-

clockwise 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 pres- sure), 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 pres- sure 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, in- conspicuous 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 trig-

ger and turn OFF the engine as directed in the engine manual. Squeeze the trigger to release system pres- sure. 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 deter- gent 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 dis-

pensed when wash wand nozzle is in the low pres- sure 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 in- jector. 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 op- eration. Press foot valve or wand trigger to release any fluid pressure in system. Always wear safety glasses and gloves when per- forming 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 pres- sure washer. Wipe the unit down with a damp cloth. Low Pressure High PressureLock OutPatternAdjustment15 KJ-2200/KJ-3100 Water Jetting Machines 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-de- tergent 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 sys- tem 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 an-

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.
