Frequently Asked Questions - KJ1350 RIDGID

How do I purge air from the system before use?

After connecting the water supply and nozzle, open the water supply valve and let water flow without starting the motor until all air is expelled through the nozzle. Then close the valve, plug in the unit, and start the motor. If maximum pressure is not reached, actuate the pulsator several times between ON and OFF to purge residual air.

Why is my drain cleaner not producing pressure?

First check that the water supply valve is fully open, the inlet filter screen is not clogged, and there are no kinks in the supply hose. Then ensure the nozzle is not obstructed. If the problem persists, purge air as described above or operate the pulsator. Finally, check the pressure regulator adjustment: turn it to the right to increase pressure.

How do I use the pulsator to navigate bends in the pipe?

For normal bends, leave the pulsator (No. 1) in the OFF position and the pulsation valve (No. 2) in OFF. If the hose stops advancing, turn the pulsation valve to ON while leaving the pulsator OFF. This produces pulses that help negotiate siphons. For very tight bends, activate both the pulsator and the pulsation valve (both ON) for more intense vibrations.

What oil should I use for the pump and motor?

Use SAE 30W detergent oil for the pump. The oil level should be checked regularly; the unit comes with oil already in place. For the electric motor, no oil is necessary (sealed motor). Consult the maintenance section of the manual for draining procedures.

How do I winterize the machine to prevent freezing?

If the machine may be exposed to sub-zero temperatures, it must be protected. Use the H-25 winterizing kit which contains special RV antifreeze (no ethyl alcohol). Fill the pump and hoses with this antifreeze following the kit instructions. Never use alcohol-based antifreeze as its discharge is prohibited.

What should I do if the nozzle is clogged?

Immediately stop the drain cleaner and close the water supply. Unscrew the nozzle and use the provided cleaning rod (H-21 tool) to clear each propulsion orifice. Insert a wire of appropriate size into each orifice. If clogging persists, also check the water inlet filter screen.

How do I use the pressure washer (washing function)?

Attach the pressure washer kit (HP-EL) to the machine outlet. Connect the wash hose and wand (HW-EL). To use detergent, connect the injector and immerse the siphon hose in the product. Adjust pressure with the regulator. Rotate the wand nozzle for a wide or narrow jet. Detergents are only dispensed in low-pressure mode (nozzle pushed forward). Never spray flammable liquids.

What are the essential electrical safety instructions?

The unit must be plugged into a grounded (3-prong) outlet. Use a ground fault circuit interrupter (GFCI) – it is integrated into the cord. Test it before each use by pressing the test button: the indicator should turn off. Never use a damaged extension cord; choose a 12 AWG model with ground, rated for outdoor use (W or W-A). Keep all connections dry and do not touch plugs with wet hands.

How do I mount the machine on the H-10 cart?

Place the drain cleaner on the cart by first engaging the front end into the housing, then aligning the rear pin. Tighten the handle to secure the unit. For the reel, insert its pin into the receptacle near the handle and tighten the handle. Ensure all handles are tightened before transporting the machine. The cart can be folded for storage by loosening the rails.

How do I test the GFCI on the cord?

Plug the cord into a power outlet. Press the test button (usually marked 'Test'): the indicator light should turn off. To reset, press the reset button ('Reset'); the light will then come back on. If the light does not turn off during the test, or if the GFCI does not reset, the cord is defective and must be replaced before further use.

General Safety Information

WARNING! Read and understand all instructions. Failure to follow all instructions listed below may result in electric shock, fire and/or serious personal injury.

SAVE THESE INSTRUCTIONS!

Work Area Safety

- Keep your work area clean and well lit. Cluttered benches and dark areas invite accidents.

RISK OF FIRE!

• Do not operate tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
• Keep by-standers, children, and visitors away while operating a power tool. Distractions can cause you to lose control.

Electrical Safety

GROUNDING INSTRUCTIONS:

- Grounded tools must be plugged into an outlet, properly installed and grounded in accordance with all codes and ordinances. Never remove the grounding plug or modify the plug in any way. Do not use any adapter plugs. Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. If the tool should electrically malfunction or break down, grounding provides a low resistance path to carry electricity away from the user.

Grounding prong Cover of grounded outlet box Grounding prong

- Avoid body contact with grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electrical shock if your body is grounded.

GROUND FAULT CIRCUIT INTERRUPTERS (GFCI):

• Water Jetter is provided with a ground-fault circuit-interrupter (GFCI) built into the power supply cord. This GFCI provides additional protection from the risk of electrical shock.
• Before using, test the Ground Fault Circuit Interrupter (GFCI) provided with the power cord to in-

sure the GFCI is operating properly. Damaged GFCI increases risk of electrical shock.

- Do not abuse cord or Ground Fault Circuit Interrupter (GFCI). Keep cord from heat, oil, and sharp edges. Damaged cords increase the risk of electrical shock.

EXTENSION CORDS:

• Use only an outdoor extension cord marked "W-A" or "W". These cords are rated for outdoor use and reduce the risk of electrical shock.
• Use only three-wire extension cords which have three-prong grounding plugs and three-pole receptacles which accept the machine's plug. Use of other extension cords will not ground the tool and increase the risk of electrical shock.
• Extension cords are not recommended unless they are plugged into a Ground Fault Circuit Interrupter (GFCI) found in circuit boxes or outlet receptacles. The GFCI on the machine power cord will not prevent electrical shock from the extension cords.
• Use proper extension cords. (See chart.) Insufficient conductor size will cause excessive voltage drop and loss of power.

Minimum Wire Gauge for Extension Cord
Nameplate Amps	Total Length (in feet)
	0 – 25 26	- 50 51 – 100
0 – 6 18	AWG 16 AWG	16 AWG
6 – 10 18	AWG 16 AWG	14 AWG
10 – 12 16	AWG 16 AWG	14 AWG
12 – 16 14	AWG 12 AWG		NOT RECOMMENDED

• Do not abuse extension cords. Keep cord from heat, oil and sharp edges. Do not yank on any cord to disconnect. Damaged cord increases risk of electrical shock.
• Keep all electric connections dry and off the ground. Do not touch plugs or tool with wet hands. Reduces the risk of electrical shock.
• Always disconnect the extension cord from the receptacle before disconnecting the product from the extension cord. Reduces risk of electrical shock.

Personal Safety

- Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use tool while tired or under the influence of drugs, alcohol, or medications. A moment of inattention while operating power tools may result in serious personal injury.

• Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts.
• Avoid accidental starting. Be sure switch is OFF before plugging in. Carrying tools with your finger on the switch or plugging in tools that have the switch on invites accidents.
• Remove adjusting keys or wrenches before turning the tool ON. A wrench or a key that is left attached to a rotating part of the tool may result in personal injury.
• Do not overreach. Keep proper footing and balance at all times. Proper footing and balance enables better control of the tool in unexpected situations.
• Use safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes, hard hat, or hearing protection must be used for appropriate conditions.

Tool Use and Care

• Do not force tool. Use the correct tool for your application. The correct tool will do the job better and safer at the rate for which it is designed.
• Do not use tool if switch does not turn it ON or OFF. Any tool that cannot be controlled with the switch is dangerous and must be repaired.
• Disconnect the plug from the power source before making any adjustments, changing accessories, or storing the tool. Such preventive safety measures reduce the risk of starting the tool accidentally.
• Store idle tools out of the reach of children and other untrained persons. Tools are dangerous in the hands of untrained users.
• Maintain tools with care. Keep valves, hoses, and nozzles in proper operating condition. Properly maintained tools are less likely to malfunction and cause injury.
• Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the tool's operation. If damaged, have the tool serviced before using. Many accidents are caused by poorly maintained tools.
• Use only accessories that are recommended by the manufacturer for your model. Accessories that may be suitable for one tool may become hazardous when used on another tool.
• Inspect tool and extension cords periodically and

replace if damaged. Damaged cords increase the risk of electrical shock.

- Keep handles dry and clean; free from oil and grease. Allows for better control of the tool.

- Should replacement of the cord become necessary, use only identical replacement parts that include GFCI protection. GFCI protection must be maintained to reduce the risk of electrical shock.

Service

• Tool service must be performed only by qualified repair personnel. Service or maintenance performed by unqualified repair personnel could result in injury.
• When servicing a tool, use only identical replacement parts. Follow instructions in the Maintenance Section of this manual. Use of unauthorized parts or failure to follow maintenance instructions may create a risk of electrical shock or injury.

Machine Inspection

WARNING

To prevent serious injury, inspect your Jetter. The following inspection procedures should be performed on a daily basis.

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

1. 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 machine. If any of these conditions are present, do not use the Jetter until any problem has been repaired.

2. 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.

⚠ WARNING When replacing cord, use only identical replacement parts that includes GFCI protection.

1. Check inlet filter screen for debris that can restrict water flow into the pump resulting in poor performance. If filter screen is dirty or clogged, remove, clean and replace.
2. 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.
3. Clean any oil, grease or dirt from all equipment handles and controls. This reduces the risk of injury due to a tool or control slipping from your grip.
4. Check the jetter nozzle orifices for debris. If an orifice is blocked, use nozzle cleaning tool to clear and remove debris.
5. Inspect hoses for wear and damage. Hoses should be replaced when they become damaged.

⚠ WARNING Damaged hoses can burst causing serious injury. Only use hoses whose pressure rating meets or exceeds that of the jetter.

Machine and Work Area Set-Up

WARNING

NOTE! Both the KJ-1350 and KJ-1750 Jetters have pulse actuators (Figure 5). The KJ-1350-2 and KJ-1750 have an additional pulse valve (Figure 7). 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 unloading 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 115 volt A/C current.

2. On the KJ-1750, adjust the unloading valve so that the pressure gauge shows 1750 PSI (green zone). At this pressure, the KJ-1750 draws approximately 17 amps when supplied with 115 volt A/C current. (Figure 4)

NOTE! Operating pressure is increased by rotating the unloading 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.

1. 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.

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 levels of pulsation with the addition of a pulse valve. There are now three different pulses:

	Actuator (#1) Valve (#2)
Normal	OFF	All	OFF
Bends & Traps OFF ON KJ-1750
Difficult Bends ON ON

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 advance 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 necessary 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 necessary to induce some pulse action.

Figure 7 – 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 7). In the pulse mode, the pump induces large pulsation and jet-ter hose vibration. Rotating the hose while operating in the pulse mode will normally overcome stubborn bends and traps.

KJ-1350-2 Negotiating Difficult 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 8)

#1 Actuator ON

Figure 8 – 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.

⚠ WARNING 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 14 " 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 Water spray should not be pointed at any human.

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 14 " ID x 35' hose provided or any 14 " 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 .letter).
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 full pressure.

⚠ WARNING Do not spray flammable liquids or toxic materials.
