Pre-Operation Inspection

WARNING

Before each use, inspect your water jetter andcorrect 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 bacteria on the equipment

Make sure that the battery isolator and engine switch is in the OFF position.
Clean any oil, grease or dirt from the equipment, including the handles and controls. This aids inspection and helps prevent the machine or control from slipping from your grip.
Inspect the water jetter and accessories for the following:
• Proper assembly and completeness.
• Broken, worn, missing, misaligned, binding or loose parts.
• Presence and readability of the warning labels. (See Figure 4.)
• Any other condition which may prevent the safe and normal operation.
If any problems are found, do not use the water jetter until the problems are corrected.

Figure 4 – KJ-5000 Warning Labels
Clean water filter (Figure 5 ). Using the drain valve, drain the tank. Unscrew the clear plastic cover from the filter and remove and clean the mesh filter. Dirt and debris can restrict the water flow to the pump and cause performance issues.
NOTICE Before screwing the plastic tank cover back on, ensure the black oring is seated correctly
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.
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 rating.
Inspect and maintain the engine per the engine operator’s manual.
Check engine fuel level. If needed, add unleaded gasoline. See engine operator’s manual for requirements. Use caution when handling gasoline. Work in a well ventilated area. Never fill the tank while unit is running, do not overfill tank and do not spill fuel.
Make sure tank cap is securely closed.
Check the oil level(s) in the pump and gear box through the sight glass and add oil if needed (see Maintenance Instructions section). Inspect Engine as directed in the engine operator’s manual.

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

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 machine 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.
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 access to the drain. Do not feed the hose through a fixture. This could damage the hose and the fixture.
Determine the correct equipment for the application.
See the Specifications section for information on the jetter. Drain cleaners and jetters for other applications can be found by consulting the RIDGID Catalog, on line at www.RIDGID.com/au/en.
Make sure all equipment has been properly inspected.
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, signs or other barriers to alert drivers.
If needed, place protective covers in the work area.
The drain cleaning process can be messy.
Take the jetter to the well-ventilated outdoor work area along the clear path. See Transportation Section. Be aware of possible slip hazards. Wear appropriate footwear to help prevent slips.

Water Supply
Run a hose from the water source to the jetter water inlet.
Use the largest diameter, shortest length hose possible.
A 3/4″ I.D. inlet hose is the minimum recommended size.
An appropriate backflow prevention device should be used to comply with all local codes and ordinances.
Dirt and debris in the water supply can cause excess pump wear, clog the jetter filter, nozzles and reduce performance. Do not use water from ponds, lakes or other sources that may be contaminated.
Fill the jetter water tank prior to starting the jetter.
The tank is equipped with a:

Low water level shut-off to prevent pump damage from insufficient water. This will shut OFF the engine when the tank water level falls below a predetermined level.
Float valve to shut-off inlet water when the tank is full, preventing water spillage through the tank vent.
By removing tank lid, the top of the tank can be removed for inspection or tank cleaning (Figure 6). NOTE: to remove the tank lid, turn/unscrew in an anticlockwise direction.

Warm water can be used for improved cleaning. Do not use water hotter than 45°C this can cause pump and/or float valve damage. When using warm 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.

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 7).
Drain Preparation

Hose Set-Up
Use care when routing jetter hoses. Routing hoses over rough surfaces, sharp edges, crossing hoses, etc. can damage the hose jacket. Keeping the jetter hose on the reel(s) will help to minimize hose damage.

The KJ-5000 is equipped with two hose reels, a primary reel mounted to the jetter frame and the remote reel which has a separate base. Typically the primary reel is equipped with larger hose suitable for jetting larger diameter drains or supplying water to the remote reel. The remote reel is typically equipped with smaller hose used for jetting smaller diameter drains.

Select a jetter hose size appropriate for the drain being cleaned. See Jetter Hose Selection Chart.
Locate the desired hose reel (primary or remote) for jetting within 1 meter 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 1 meter of the drain opening, extend the drain opening back to the hose reel with similar sized pipe and fittings (Figure 7).
Water Control Valve. Choose the valve to be used to control water flow.
If using a foot valve to control water flow, route a hose from the jetter pump to the IN fitting on the foot valve.
Connect the hose on OUT fitting of the foot valv e to the hose reel to be used. Connect so that the foot valve hose feeds into the ball valve on the hose reel. (See Figure 8.)

If not using the foot valve, use the ball valve on the reel being used to control water flow. Route a hose from the jetter pump into the ball valve on the hose reel. Make sure quick connect fittings are secure.
Position the reel for accessibility. You must be able to control the jetter hose and the water control valve.
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
Select a nozzle and attach. 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.
Many nozzles attach to the hose with a quick connect. To attach, pull the collar back, fully insert the male end of the quick connect mounted on the nozzle and release the collar (See Figure 9). Confirm that the connection is secure. This will reduce the risk that the nozzle is lost during use.

Only use nozzles for the pipe sizes they are rated for.
Using a nozzle designed for smaller pipe sizes in larger diameter pipe increases the risk of the nozzle changing direction in the drain, exiting at the user and causing serious injury.
If using the Reverse Root Cutting nozzle for drains larger than 6″/150 mm and up to 10″/250 mm, an extension must be used to reduce the risk of the nozzle changing direction in the drain, exiting at the user and causing serious injury. For drains 6″/150 mm and smaller, no extension is needed. If needed, firmly hand tighten the extension to the nozzle – do not over tighten. See Figure 10.

This nozzle is exceptionally small and short and has three rear jets with one facing forward for a range of more domestic applications e.g. internal drains/pipes etc. Nozzle includes a 1/8″ BSPT thread to connect directly to hose thread as supplied standard.|

H-500

| Reverse Root Cutting Nozzle: Use to clear roots and other type of blockages. Uses a rear facing oscillating jet for more complete drain cleaning. Attaches to hose with quick connect. For drain sizes 4″ to 10″, as noted here.

WARNING If using the Reverse Root Cutting nozzle for drains larger than 6″/150 mm and up to 10″/250 mm, an extension must be used to reduce the risk of the nozzle changing direction in the drain, exiting at the user and causing serious injury.

|

If using nozzles that are not equipped with a quick connect (such as the Macro Drain Nozzle), the female quick connect must be removed from the end of the hose and the nozzle securely threaded on.

Stock hoses and nozzles use BSPT threads. Make sure that the threads match and that sealant is used to prevent leaks.

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 45°C (inlet water temperature). This increases the risk of injury, including burns, and damage to the jetter.
One person must control the jetting process and water flow. If the jetter hose comes out of the drain, the operator must be able to shut off the water flow 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.

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.
Insert the hose with nozzle attached into the drain at least 1m (3ft) so that the end of the hose will not come out of the drain and whip around when the machine is started.
Turn the battery isolator switch ON and confirm the Emergency stop button is in the out position (rotate button clockwise) (Figure 11A & 11B). Open the fuel tap.
Confirm that the water supply is turned on and the water tank is full. Never start the engine without the water supply turned ON. This can damage the pump.
Grip the hose near the pipe opening. Open the selected water control valve (ball or foot valve). Following the starting instructions supplied in the engine manual, start the engine. Set the throttle to the full open position. Confirm that water flows freely through the nozzle. Close water control valve. When the water control valve is closed and the jetter is running, the unloader valve will recirculate water back to the tank.
Allow the engine to warm up.
If needed, turn the unloader valve while monitoring the pressure gauge on the unloader valve to adjust the pressure as desired (clockwise to increase pressure, counter-clockwise to decrease pressure).
Do not exceed the machine pressure rating. Do not force the unloader valve or use wrenches or tools to turn. This will damage the unloader valve. Pressure gauge on the remote reel will read lower than unloader valve gauge, depending on hose size and length.Jetter| KJ-5000
---|---
Pressure Rating| 5075 psi

If the jetter will not generate the rated pressure or is erratic

  * Make sure the engine throttle is properly adjusted to the full open position.
  * Turn unloader valve clockwise to increase pressure.

Do not force.

  * 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 tank and filter and make sure that they clear of debris.
  * Make sure there is adequate water flow to the jetter.
  * Turn the jetter OFF. Remove 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.

Assume a proper operating position.
- Be sure you can control the ON/OFF action of a water control valve (ball valve or foot valve). Do not turn the valve ON yet. In case of emergency you must be able to turn off water flow.
- 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.

WARNING When using the remote reel ensure the Primary Hose Restraint is connected and clipped in to the Remote Reel eyelet connection point, using the hose restraint carabineer to clip into the eyelet, to stop hose from whipping in the unlikely event of a hose end failure.

Ensure the Primary Reel Restraint is taken off when going back to primary reel operation and put it back on when using the remote reel.
Operating Instructions

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 (Figure 2). With at least 1m (3 ft) of hose in the drain and one hand on the hose to control its movement, open the flow control 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 13.
Use a flexible leader or smaller diameter 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.

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.
If the water level in the water tank falls below ¼ full, the float valve will turn the engine OFF. Generally, at this point you must allow the tank to refill before restarting the jetter. If that does not work, see troubleshooting section.
Once the nozzle is the desired distance into the drain, slowly (0.3m/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 end.

With hose still in the drain, turn OFF the engine as directed in the engine manual, and open water control valveto 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.
Draining Water from System
Draining machine will reduce the jetter weight for transportation and minimize the chance of water spillage.
To drain the tank, attach a hose to the tank drain and open valve. Once the tank is empty, disconnect the quick connect from the hose reel and allow water to drain from pump and hoses.
If using the jetter in cold weather conditions, see MachineStorage for information on freeze protecting.

Using Water Jetter Machine as a Pressure Washer
This RIDGID water jetting machine can also be used as a pressure washer. Use as a pressure washer is similar to use as a jetter, and those instructions should be used in conjunction with the following.

Locate an appropriate work area
Make sure all equipment has been properly inspected
Attach the wash wand to the jetter hose using the quick connect coupling. Make sure the hose is securely connected to prevent it from coming off under pressure. When using the jetter as a pressure wash, the wash wand acts as the water control valve. Open other valves in the system to allow water to flow
Connect an appropriate water supply, as discussed earlier, to the jetter. Never start the engine without the water supply turned ON. This can damage the pump.
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 (Figure 14).
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. Set the throttle to the full open position. Allow the engine to warm up. Release the trigger soon after the engine starts.
With the wand pointed in a safe direction, squeeze the wash wand trigger. If applicable; 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

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.
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.
Do not allow the jetter to run for extended period of time with the trigger OFF. When the trigger is OFF, water recirculates and it causes the water to heat up.
Once pressure washing is complete, release the trigger and turn OFF the engine as directed in the engine manual. Squeeze the trigger and ensure all water control valves are also in open position to release system pressure. Never leave the system pressurized.

Hose Reel Brake Adjustment

The reels are equipped with an adjustable brake to prevent the hose from playing off the reel under its own weight.
Flicking (tightening) tension brake engages drag on the reel, loosening decreases the drag. Adjust as desired. The brake only works in one direction (to resist hose moving off reel) (Figure 15).
Hose Reel Brake Adjustment

Pump Lubrication/Maintenance
Check the pump oil level prior to each use. Place the jetter on a level surface. Wipe any dirt and debris from the area of the dipstick and sight- glass. Oil level should be at the middle of the sight-glass (Figure 16). If needed, remove the dipstick and add SAE 15W-40 Mineral non-detergent oil, fill to half-way on the sight-glass. Do not overfill, reinstall dipstick.
Pump Lubrication/Maintenance

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 to approximately half-way on the sight-glass with SAE 15W40 Mineral non-detergent oil using the checking procedure.
Approximately 1000 ml of oil are required to change the pump oil.
At 1000 hours of use (less in severe use conditions) the KJ-5000 should be taken to a RIDGID Authorized Independent Service Center for pump seal and valve service.

Gearbox Lubrication
Check the gearbox oil level prior to each use. Place the jetter on a level surface. Wipe any dirt and debris from the area of the dipstick and sight- glass (Figure 16). Oil level should be at the middle of the sight-glass. If needed, remove the dipstick and add SAE 85W-140 gear lubricant oil, fill to half-way on the sight-glass. 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 to half-way on the sight-glass with SAE 85W-140 gear lubricant oil. Approximately 300 ml of oil are required to change the gearbox oil.

Preparing Pump for Cold Weather Storage
NOTICE If the jetter will be stored under conditions where the temperature is near or below 0°C, the jetter must be properly prepared. If water freezes in the pump, it can damage it.
After the tank is drained, remove the hose from the water inlet filter. 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.
