Standard Equipment All Jetters come with

• Appropriate Jetter Nozzles

• Nozzle Cleaning Tool See the RIDGID catalog for specific equipment supplied with each catalog number. This machine is made to clean drains. If properly used it will not damage a drain that is in good condition and properly designed, constructed and main- tained. If the drain is in poor condition or not properly 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 condition of a drain before cleaning is through visual inspection with a camera. Improper use of this jetting machine can dam- age the jetter and the drain. This machine may not clear all blockages. Machine Assembly WARNING To prevent serious injury during use and prevent machine damage, follow these procedures for proper assembly. Instructions for Pump Remove plug in pump and replace with dipstick/breather cap. Check the pump oil level (jetter is shipped with oil). If oil is low, fill with SAE 30W non-detergent oil. Transport Carts H-10 Cart The two-wheeled cart has been designed to accept the KJ-1350 and the KJ-1350-2 without the need of tools. Lift and slide the jetter onto the cart making sure the one end engages the cart and on the other end, the post inserts into the receptacle (Figure 2A). Tighten the T-handle to lock the jetter down. An adapter kit is available to mount the KJ-1750 on the H-10. The hose reel and 100 feet of

/4" ID jetter hose mounts to the receptacle closest to the handle (Figure 2B). Place the post on the reel into the socket and tighten the T-handle. The length of the H-10 transport cart can be shortened for storage or lengthened by loosening two T-handles on the rails and sliding the handle in or out. Make sure all T-handles are fully tight- ened prior to transporting or lifting. H-30 Cart and Hose Reel The larger H-30 Cart and Hose Reel is designed to ac- cept the KJ-1750 without the need of tools. Lift the jetter onto the deck and place over the locator pins. Hold in place and attach front and back clips to jetter base. An adapter kit is available to mount the KJ-1350’s to the H-30. Figure 2A – Water Jetter, H-10 Cart and Hose Reel Figure 2B – Water Jetter with H-10 Cart and Hose Reel Pre-Operation Inspection WARNING Before each use, inspect your water jetter and correct any problems to reduce the risk of serious injury from high pressure water and other causes and prevent jetter damage. Always wear safety glasses, gloves and other appropriate protective equipment when inspecting your jetter to protect against chemicals and bacte- ria on the equipment.

1. Check pump oil level. If low, fill with a SAE 30 weight

non-detergent oil. NOTE! Jetter unit should be stored base down. Never NOTICE Reel PostJetter ReceptacleJetter PostT-HandleHose Reel Receptacle WARNING7 KJ-1350 & KJ-1750 Jetter Machines

278-105-671.10_REV C

store in up-right position as oil from pump will leak from reservoir.

2. Inspect the Jetter for any broken, missing, misaligned

or binding parts as well as any other conditions which may affect the safe and normal operation of the ma- chine. If any of these conditions are present, do not use the Jetter until any problem has been repaired.

3. Inspect the power cord, ground fault circuit interrupter

(GFCI) and plug for damage. If the plug has been modified, is missing the grounding pin or if the cord is damaged, do not use the jetter until the cord has been replaced. When replacing cord, use only identical replacement parts that includes GFCI protection.

4. Check inlet filter screen for debris that can restrict

water flow into the pump resulting in poor perfor- mance. If filter screen is dirty or clogged, remove, clean and replace.

5. Use accessories that are designed for your Jetter

and meet the needs of your application. The correct accessories allow you to do the job successfully and safely. Accessories suitable for use with other equipment may be hazardous when used with this machine.

6. Clean any oil, grease or dirt from all equipment han-

dles and controls. This reduces the risk of injury due to a tool or control slipping from your grip.

7. Check the jetter nozzle orifices for debris. If an orifice

is blocked, use nozzle cleaning tool to clear and re- move debris.

8. Inspect hoses for wear and damage. Hoses should

be replaced when they become damaged. Damaged hoses can burst causing seri- ous injury. Only use hoses whose pressure rating meets or exceeds that of the jetter. Machine and Work Area Set-Up WARNING Always wear safety glasses, gloves and other appropriate protective equipment when setting up your jetter to protect against chemicals and bacteria on the equipment. Rubber soled, non-slip shoes can help prevent slipping on wet surfaces.

Set up the jetter and work area according to these procedures to reduce the risk of injury from high pressure water, chemical burns, infections, electric shock and other causes, and prevent jetter damage.

1. Check work area for:

• No flammable liquids, vapors or dust that may ig- nite.

• 20 amp grounded electrical outlet.

• Clear path to the electrical outlet that does not contain any sources of heat or oil, sharp edges or moving parts that may damage electrical cord.

• Dry place for machine and operator. Do not use the machine while standing in water.

• Water supply. NOTE! If a connection is made to a potable water sys- tem, the system should be protected against backflow in accordance with all local codes and ordinances.

2. Connect the quick coupling fitting to the water supply

hose. Connect water supply hose to the jetter inlet and close the inlet supply valve. (Figure 3) Figure 3 – Connect Water Supply Hose to Jetter. Close Inlet Supply Valve (Shown In Closed Position.)

3. Connect the other end of the water supply hose to the

water faucet and turn the faucet on. Make sure there WARNING WARNING Water Supply HoseJetter Water InletInlet Supply ValveKJ-1350 & KJ-1750 Jetter Machines

are no kinks or unnecessary bends in the supply hose. Hot water improves the jetter’s perfor- mance, particularly when clearing grease blockages. Limit water temperature to below 140°F.

4. Connect a jetter hose to the jetter’s outlet quick cou-

pling on the end of the connection hose. (Refer to Jetter Hose Selection Chart.)

5. If a hose reel is used, attach connection hose to plug

fitting on hose reel.

7. Open the inlet supply valve and run water through the

jetter and hoses with unit OFF.

8. Continue to run water through the jetter until all air

9. Close the inlet supply valve.

NOTE! Both the KJ-1350’s and KJ-1750 Jetters have check valves for back flow prevention.

10. Attach a jetter nozzle to the jet hose. (Refer to Jetter

Nozzle Selection Chart.) Hand-tighten for a snug fit. Over-tightening can interfere with water flow through the nozzle orifices causing reduced flow and poor performance. Nozzles should not be removed from the drain while pressurized. Mark the hose at a distance of 24" (60cm) from nozzle to indicate the location of the nozzle.

11. Insert the jet hose into the line several feet.

12. Open the inlet supply valve and verify that water flows

freely through the nozzle.

13. Plug the Jetter into the electrical outlet making sure to

position the power cord along the clear path selected earlier. If the power cord does not reach the outlet, use an extension cord in good condition. To avoid electrical shock and electrical fires, never use an extension cord that is damaged or does not meet the following requirements:

• The cord has a three-prong plug similar to shown in Electrical Safety section.

• The cord is rated as “W” or “W-A” if being used outdoors.

• The cord has sufficient wire thickness (12 AWG). If the wire thickness is too small, the cord may overheat, melting the cord’s insulation or causing nearby objects to ignite. To reduce risk of electrical shock, keep all electrical connections dry and off the ground. Do not touch plug with wet hands. Test the Ground Fault Circuit Interrupter (GFCI) provided with the electric cord to in- sure it is operating correctly. When test button is pushed in, the indicator light should go off. Reactivate by pushing the reset button in. If indicator light goes on, the machine is ready to use. If the GFCI does not function correctly, do not use the machine.

Operating Instructions WARNING Risk of eye injury. Spray can splash back or propel objects. Always wear properly rated eye protection such as safety goggles or face shield while spray- ing. (Safety glasses do not provide full protection.) 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 uid 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. 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 eye protec- tion and gloves, and may also include equipment such as latex or rubber gloves, protective clothing, respirators, and steel toed footwear. Follow operating instructions to reduce the risk of injury from whipping hoses, high pressure liquid injection, electric shock and other causes. Start-Up and Pressure Adjustment NOTE! Both the KJ-1350 and KJ-1750 Jetters have pulse actuators. The KJ-1350-2 and KJ-1750 have an additional pulse valve (Figure 5). Both the pulse actuator and pulse dampener valve must be in the OFF position prior to turning the jetter switch ON. To obtain maximum pressure, both pulse controls must be OFF.

1. Turn the unloader valve counter-clockwise to insure

the pressure is backed down. Turn jetter switch ON and adjust the unloader valve so that the pressure gauge shows a maximum of 1350 PSI (green zone) on the KJ-1350 and KJ-1350-2. At this pressure, the KJ-1350 Jetters draw approximately 14 amps when supplied with 120 volt A/C current.

2. On the KJ-1750, adjust the unloader valve so that the

pressure gauge shows 1750 PSI (green zone). At this pressure, the KJ-1750 draws approximately 17 amps when supplied with 120 volt A/C current. (Figure 4) NOTE! Operating pressure is increased by rotating the unloader valve clock-wise +. If electrical circuit is not dedicated to Jetter, it may be necessary to reduce pressure (amp draw) to prevent tripping the circuit breaker or blowing a fuse. Figure 4 – Adjust The Unloader Valve

3. If the jetter will not generate pressure:

• Make sure the water faucet is completely open and the inlet supply valve is open.

• Check the filter screen at the inlet port to the jetter. Make certain it is clear of debris.

• Cycle the pulse actuator on the KJ-1350 and KJ- 1750 ON and OFF several times while the jetter is running to clear any trapped air in the system.

• Cycle the pulse dampener valve on the KJ-1350-2 and KJ-1750 ON and OFF several times to clear trapped air.

• Rotate unloader valve clockwise to make sure it increases pressure. Figure 5 – Pulse Actuator/Pulse Valve OFF Pulse Control Valves The KJ-1350 and KJ-1750 Jetters have a pulse actuator on the pump. Rotating the lever clockwise will engage the

pulse. The KJ-1350-2 and KJ-1750 Jetters have two lev- els of pulsation with the addition of a pulse valve. There are now three different pulses: For optimum jetter performance, you must understand the proper use of the pulse actuator and pulse valve. Normal Jetting Turn pulse actuator (#1) to the OFF position. Turn the pulse valve (#2) on the KJ-1350-2 and KJ-1750 to the OFF position. This results in maximum pressure but no pulse action.

1. When the jetter nozzle encounters a bend, its ad-

vance will usually slow or stop. The jetter hose has a slight bend or set to it. The reverse thrust of the nozzle will advance the jetter hose but it is also nec- essary to manually feed and rotate the jetter hose to work the set around the bends.

2. If the hose won’t advance, pull back on the hose

slightly and rotate the hose a quarter to a half turn. Then advance the hose forward.

3. If the jetter hose is not advancing, it may be neces-

sary to induce some pulse action. Figure 6 – Negotiating Bends and Traps Using the Pulse Mode to Negotiate Bends and Traps In some cases, simply rotating the hose will not be enough to negotiate a bend or trap. In these instances, turn the pulse actuator (#1) to the OFF position and valve (#2) for KJ-1350-2 and KJ-1750 to the ON position (Figure 6). In the pulse mode, the pump induces large pulsation and jetter hose vibration. Rotating the hose while operating in the pulse mode will normally overcome stubborn bends and traps. Negotiating Difcult Bends (w/KJ-1350-2 and KJ-1750) By turning the pulse actuator (#1) and the pulse valve (#2) to the ON position on the KJ-1350-2 and the KJ- 1750 will achieve a higher amplitude of pulse. This will allow the jetter hose and nozzle to vibrate and negotiate difficult bends. (Figure 7) Figure 7 – Negotiating Difficult Bends NOTE! In the pulse mode, the jetter’s pressure gauge will read approximately 400 - 600 PSI. NOTE! If at any time during the jetting process the pressure 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 filter 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 retrieving 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 restore 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. 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

/4" 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 the manifold and submerse the other end into a liquid solution. Washer Operation WARNING Do not use jetter within range of persons unless they wear protective clothing. High pressure jets can be dangerous if subject to misuse. The jet must not be directed at persons, live electrical equipment or the appliance itself. Do not direct the jet against yourself or others in order to clean clothes or footwear. During use of high pressure cleaners, aerosols may be formed. Inhalation of aerosols can be hazardous to health. Risk of explosion - Do not spray ammable liquids. The employer shall perform a risk assessment in order to specify the necessary protective measures regarding aerosols, depending on the surface to be cleaned and its environment. Respiratory masks of class FFP 2, an equivalent or higher are suitable for the protection against hydrous aerosols. To utilize the pressure wash feature make sure both pulse valves are in the OFF position. Adjust system pressure with the wash wand activated. The wash wand will fit the

/4" ID jetter hose. 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
