SAVE THESE INSTRUCTIONS!

WORK AREA SAFETY

1. All installations must comply with local codes. Contact your plumber, utility company, or the selling distributor for specific details.
2. Risk of explosion. Do not spray flammable liquids or operate in an area where flammable or explosive materials are used or stored. Power tools create sparks that may ignite dust and fumes.
3. Keep bystanders, children, and visitors away while operating the machine. Distractions can cause you to lose control.

PERSONAL SAFETY

1. High pressure developed by jet machines will cause personal injury. Water spray should not be pointed at any person. High-pressure spray can result in serious injury. If fluid seems to have penetrated the skin, seek emergency medical attention at once.
2. Grip the jet hose or spray the wand securely with both hands before starting the machine. Failure to do so could result in injury from a whipping hose or wand.
3. Always wear eye protection and rubber gloves. Safety equipment, eye safety devices, non-skid safety shoes, and protective clothing must be worn when using this equipment.
4. Do not touch the engine during operation. The muffler and other parts of the engine get hot and can cause severe burns.
5. Do not smoke while filling the engine fuel tank. Fumes can ignite causing property damage and severe injury.
6. Stay alert, watch what you are doing, and use common sense when operating a power tool. Do not use tools while tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating power tools may result in serious personal injury.
7. Dress properly. Do not wear loose clothing or jewelry. Con- tain long hair. Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts.

SERVICE

1. Tool service must only be performed by qualified service personnel. Service or maintenance performed by untrained personnel could result in injury and damage to the equipment.
2. When servicing tools, use only identical replacement parts.
   Follow the instructions in the maintenance section of this manual.
   Use of unauthorized parts or failure to follow maintenance instructions may cause injury or damage to equipment.

JET SAFETY

1. Do not operate a jet above-rated pressure or above 140 degrees (rated water temperature). Operating a jet above rate specifications risks damage to the pump and related components and will void the warranty.
2. Do not operate the jet with the output valve in the off position for extensive periods. This will cause the water to overheat and damage the pump.
3. Never run a pump without water in it. Operating the machine without water will cause the pump to fail and void the warranty.
4. Check for worn hose and components before each use. Check that all fittings are secured before using the jet. Worn or loose fittings can cause damage to the machine and injure the operator.
5. Protect the machine and pump from freezing. Storing or operating the jet in temperatures below freezing can damage the pump, hose, and other jet components. Store the unit indoors or protect it with antifreeze when not in use.
6. General Wire Spring Co. will not be liable for any changes made to our standard machines or any components not purchased from General Wire Spring Co.

JM-3080 SPECIFICATIONS

BATTERY SPECIFICATION

• Lawn Tractor Battery
• 175 CCA
• Battery Box Size: 8 1/2” L x 6” W x 6 1/4” H (Battery can be slightly taller and still be covered by the lid.)
• The battery should have a lifting strap for easy installation.

BUFFER TANK
The J-3080 is equipped with a 12-gallon buffer tank. If the incoming water flow is less than 8 gpm required by the pump, the buffer tank will protect the pump from cavitation and damage. For instance, if your water supply can only provide 6 gpm, you can still run the jet for 8 minutes before stopping to let the holding tank refill.

REMOVABLE HOSE REEL
This Jet features a removable hose reel. It easily detaches in seconds for remote operation. To remove the reel, unscrew twist connect at the control panel outlet, then simply pull the knob at the base of the reel, and lift the reel. To reattach the reel, align the base of the reel in the carriage, then allow the knob to snap back into place.

JET HOSE

1. When selecting hose size, consider that pressure is lost as the water travels down the length of the hose. As the length increases, the pressure decreases. In addition, the smaller the diameter of the hose, the greater the loss of pressure per foot will be. As an example, at 4 GPM, a 3/8” hose will lose 90 lbs. of pressure over a 100 ft. length. The gauge reflects pressure from the pump only, no pressure at the end of the hose. It is important to select the largest possible hose size to have as much pressure as possible at the end of the hose.
2. Hoses of the same diameter may be coupled together using the CC-1 coupling, but it is not recommended for use in lines smaller than 8” in diameter. The long length of the hose connectors and coupling together can get caught in bends in the line. It is not advisable to have two different hose sizes coupled in a drain line. There is a tremendous loss of pressure when combined, aside from the difficulty of getting around bends.

HOSE SELECTION GUIDE

JET NOZZLES

1. A variety of jet nozzles are available for drain cleaning. Each has a different spray pattern and purpose. Some nozzles may have an orifice in the front to cut through the stoppage. All will have holes in the back to drive the hose down the line and clean the walls of the pipe. A tight spray pattern (15°) has more driving power for long runs, and a wide spray pattern (40°) does a better job of cutting the grease off of the walls of the pipe. A combination of nozzles may be required to clear a line. Always turn off the machine and turn off the output valve before changing nozzles.
2. Make sure the nozzle you are using matches the pump size. A 3000 psi pump requires a different nozzle orifice than a 1500 psi pump. Mismatching nozzles with pump size will either cause too little pressure, which may not clear the drain, or too much pressure, which may damage the machine.
3. Check nozzles before and after each use for clogged holes which can cause pressure to increase to dangerously high levels and damage the pump. A clogged hole can be cleared by simply using the NCT Nozzle Cleaning Tool.
4. Use the nozzle selection guide to determine what nozzle you will need for various applications. Examples: If a nozzle is stamped #111, it is a JN-111, drilled for 8 GPM @ 3000 PSI with several 15° rear jets and one forward cutting jet.

• Powerful penetrating nozzle cuts through grease and ice.
• A wide spray flushing nozzle cleans the inside of the pipe thoroughly.

ROTARY NOZZLES
Rotary nozzles are useful as a finishing tool. After the line has been cleared, you may switch to the rotary nozzle to more thoroughly clean the walls of the pipe. Use these nozzles only in a predominantly straight run since they are longer than regular nozzles and may get caught in tight bends

CHAIN SAW NOZZLES
Chain saw nozzles spin at up to 10,000 rpm to rip through roots. Lengths of chain can be quickly and easily switched for different diameter pipes.

NOZZLE SELECTION GUIDE

JET ASSEMBLY

• Upon arrival, inspect the shipping crate for damages. Uncrate and examine all parts. Note any damage to the machine or components for claims against the freight carrier.
• Jet must be stored and operated in a horizontal position. Never store in an upright position or oil may leak from the pump. If low, fill with SAE 30-weight non-detergent oil.
• Gas jets are shipped with oil in the engine. Consult the motor manufacturer’s guide for the correct weight and amount.
• Jet machines are meant to be used at or near the working area and under operator supervision. If the machine must be located out of sight of the operator, special controls may be required for proper machine operation and operator safety

OPERATION

SET-UP

1. Locate the jet near the drain line on a level surface with drainage.
   Tip: Ideally, the drain line should be cleared from the downstream side, that is, from the street back toward the house. If you must clear the line from the drain toward the street, you may need to use a siphon pump to clear away excess water.

2. Check the oil level in the pump. If low, fill with SAE 30-weight nondetergent oil.

3. Check the oil level in the engine. If low, fill with oil weight recommended in the motor manufacturer’s manual.

4. Check the inlet filter to make sure it’s clean before each use. To clean, unscrew the filter cap, remove the screen, and rinse thoroughly with water. Then, replace screen.

5. Check that the incoming water supply is clean and free of debris. Turn the water source on for at least 15 seconds to remove any possible debris in the water before connecting the hose to the water inlet

6. Connect one end of a water supply hose (not included) to the water supply and the other end to the water inlet of the jet machine. Water supply must be a minimum of 20 psi and not to exceed 100 psi. Caution: Water temperature must not exceed 140 degrees or damage to the pump can occur. Use only heavy-duty 3/4” hose of no more than 50 ft. in length. If run without an adequate water supply, the pump will cavitate. Cavitation causes the pump to vibrate, causing damage to the pump. Note: Lack of water supply can lead to seal damage, causing a loss of pressure, and will void the warranty to the pump.

7. Maximum temperature from the water source should not exceed 140°F (60°C). Using water hotter than 140°F (60°C) can cause damage to the pump and void the warranty. If the jet is being used to clear ice blockages, see instructions on Ice Blockages.

8. Select the proper hose diameter for the line to be cleaned. When using a new hose, run water through it to clean it out before attaching the nozzle.

OPERATION

NEVER POINT THE END OF THE JET HOSE AT A PERSON WHILE OPERATING.

1. Select the correct jet hose size to match the line size you are clearing. (See Hose Section Guide) Check all hoses for wear and damage. Tighten all connections securely.
2. Select the correct nozzle and attach to the end of the hose. (See Nozzle Selection Guide) Note: If you are using a new jet hose, run water through it to flush out debris before connecting a nozzle.
3. Insert the jet hose 2 to 3 feet into the drain line before turning on the machine.
4. Turn on the water supply valve fully to allow for maximum flow.
5. Turn on the jet output valve and allow water to run through the supply hose, jet, and jet hose to purge air from the system before turning on the machine.
6. Make sure that the output valve is turned on and the water is flowing.
7. Start the engine using the Engine Start-up procedures listed below.

GAS ENGINE START-UP

1. Make sure that the ball valve is turned on and water is flowing.
2. Move choke lever to the closed position. Note: Do not use a choke if the engine is warm or the ambient air temperature is high.
3. Move the throttle lever to the midpoint position.
4. Turn the engine switch to the ON position.
5. Turn the key to start the engine.
6. As the engine warms up, gradually move the choke lever to the open position.
7. Position the throttle to the desired engine speed.
8. Guide the jet hose into the drain line. Do not feed the hose continuously, but rather, move the hose forward and back to allow the pressure to break up the stoppage and the water flow to flush it away. If you are clearing the line from the upstream side, this may take more time. Clearing the line from the downstream side allows debris to flow away easily.
9. It is often helpful to turn on the Vibra-pulse valve. The vibration generated helps to hose overcome the friction in the line and glide farther down the line. See the Vibra-pulse section.
10. When the jet hose encounters a bend in the line, its advance may slow or stop. The hose has a slight curve to it from the hose reel. It may be necessary to manually feed or rotate the jet hose to work it around the bends. If the hose won’t advance, put the hose in a loop and rotate it a quarter to half turn so the curve of the hose matches the pipe. It may also be necessary to pull the hose back six inches and snap it forward to hop across a gap in the pipe fitting.
11. Once you reach the stoppage, move the hose back and forth through the section several times to ensure the line is thoroughly cleared. You may also switch nozzles to a wide spray or rotary (optional) nozzle for wall-to-wall cleaning action.

VIBRA-PULSE®
Pulsation makes the hose vibrate, helping the jet go longer distances and around tight bends more easily. The pulse control valve is located on the front of the pump. Simply turn the valve on to engage the pulse. Vibra-pulse is most effective in a 1/8” hose. You’ll notice less vibration with a 1/4” hose and almost none with a 3/8” hose. However, the pulse is still effective, causing the water to burst from the nozzle hundreds of times per second. If you are still having difficulty getting the hose around a tight bend, switch to a smaller diameter hose. Turn the pulse off before turning the machine off.

SHUT DOWN INSTRUCTIONS
After drain cleaning or spray washing is completed, run clear water through the system. Always leave the output valve in the on position when turning off the motor. Turn off the water supply and drain as much water from the pump as possible. Remove the water supply hose from the inlet. If you are in a cold climate, see the Freeze Protection section.

SPECIAL APPLICATIONS

ICE BLOCKAGES
High pressure water can be used to clear an ice blockage. A 3000 psi gas jet can clear a 4” line at an approximate rate of one foot per minute. The smaller, electric jet will take twice as long. Ambient air temperature will affect these times. Use a 15° nozzle with a forward jet. DO NOT allow the incoming water supply to exceed 140°F (60°C) or it could cause damage to the pump. Remember to follow the cold weather precautions found in the Freeze Protection section.

FREEZE PROTECTION
To protect your machine from severe damage caused by water freezing inside the components, it is important to winterize it whenever it is subjected to freezing temperatures.
The best way to protect the system is to keep it out of the cold. Barring that, the next best way is to flush the system with anti-freeze. To do so, simply attach a short garden hose (not to exceed four feet) to the inlet on the pump and put the other end into the anti-freeze container. Be sure to remove the nozzle from the hose. Turn the machine on to draw anti-freeze into the system. When anti-freeze flows out of the end of the hose, turn the machine off. Connect the high-pressure hose and trigger, and follow the above procedure. Cycle trigger on/off so that the anti-freeze will flow into the unloader and injector section of the machine.

When preparing to operate equipment for the next job, remove the anti-freeze. To do so, reconnect the water source, turn the pump on, and direct the flow of anti-freeze back into the container. Be careful not to dilute anti-freeze with the incoming water supply. Anti-freeze, if kept relatively undiluted, can be used again and again. Hoses can also be protected from freezing by using compressed air to clear them of residual water. Remember to remove the nozzle from the jet hose and hold the trigger of the spray wand in the open position.

ADJUSTING PRESSURE UNLOADER
The machine is equipped with a regulating pressure unloader to prevent pressure overload if the nozzle is clogged or the output valve or spray wand trigger is off. When the machine is in bypass mode, the pump will continue to run. However, running in bypass mode for extended periods will cause damage to the pump – no more than 5 minutes. Excessive temperatures will damage the pump and void the warranty.

The machine also comes with thermal overload protection. When the water temperature in the pump increases to 140°F (60°C), the thermal relief valve will release hot water and allow cool water to enter the pump from the freshwater supply.
To adjust the unloader, loosen the lock nut and turn the knob counter- clockwise to decrease pressure and clockwise to increase pressure. Caution: Do not over-tighten the unloader. Tighten the lock nut after adjustments are made.

ACCESSORIES

HANDY-REEL WITH FOOT PEDAL – Cat # HM-200-W (OPTIONAL)
The Handy-Reel allows for remote application of the jet. The jet can be positioned at ground level, while the Handy-Reel can be carried up on a roof to clear vents and stacks. With the help of the Handy-Reel, gas jets can be used for indoor applications while the machine operates safely outside.

The Foot Pedal interrupts the flow of water between the pump and the nozzle while leaving both hands free to guide the hose. Position the Handy-Reel at the drain site. Connect the jet machine to the inlet on the Foot Pedal. Select and attach a nozzle to the hose on the reel. Put the hose 2 to 3 ft. into the drain line. Follow the start-up procedures.

FOOT PEDAL ONLY – Cat # FM-1 (OPTIONAL)
The Foot Pedal can be used with any jet manufactured by General. It interrupts the flow of water between the pump and the nozzle while leaving both hands free to guide the hose. The pump will continue to run in by-pass mode. Do not leave the pump in the by-pass for more than a few minutes or the pump can be damaged. (See Pressure Unloader)

The Foot Pedal may be connected either at the machine or remotely at the drain site. To use the foot pedal at the machine, remove the hose going to the swivel on the hose reel and attach it to the inlet side of the Foot Pedal. Then, connect the accessory hose (available in 6 ft., 25 ft., or 50 ft. lengths) between the outlet of the pedal and the swivel on the hose reel. Some jet models may need the added length of the accessory hose on the inlet side of the pedal.

For remote operation, pull the hose from the hose reel to the drain site. Attach the hose to the inlet of the pedal. The pedal is designed for 3/8” hose fittings. If using a 1/4” hose, use the AD-1 adapter, as well. Then, attach the smaller hose (1/8” or 1/4”) to the outlet side of the pedal. Use the smaller hose to clear the drain line.

SPRAY WAND – Cat # SWA-3080

CAUTION: USE CAUTION WHEN PRESSURE WASHING. WEAR GOGGLES AND RUBBER GLOVES AND BOOTS. ANALYZE THE ANGLE OF THE SPRAY AND ANTICIPATE THE ANGLE OF THE BACK SPLASH. DO NOT POINT SPRAY AT ANYONE, INCLUDING YOURSELF. DO NOT PUT YOUR HAND IN FRONT OF WATER SPRAY. IT CAN PENETRATE THE SKIN AND CAUSE A NEED FOR AMPUTATION. IT IS BEST TO START AT A 45° ANGLE AT A 7 TO 10 FT. (2 TO 3M) DISTANCE FROM OBJECT TO BE CLEANED. DIRECT SPRAY AT CLOSE RANGE CAN BE POWERFUL ENOUGH TO CAUSE DAMAGE.

The Spray Wand can be used to clean your truck or other applications. Caution: Never clean the machine with its spray. Follow the same procedures listed previously for safety, set-up, operation, and maintenance. To operate the spray wand with your water jet, disconnect to twist the connection at the output valve. Then, connect the spray wand hose, trigger, and wand at the output valve. Turn on the water supply, then squeeze the trigger to purge air from the system. Continue to squeeze the trigger as you turn on the machine.

Hold the high-pressure spray nozzle approximately 6 – 8 ft. from the surface to be cleaned. When cleaning with a detergent, apply from the bottom up with an even left-to-right movement. Rinse from the top down with a similar motion. This will help reduce potential streaking. Always apply soap to a dry surface. This will enhance penetration and deter-gent cling and reduce dilution of detergent with an already wet surface.

You may draw soap through the spray wand in conjunction with the optional chemical injector. First set up the Chemical injector system (see Chemical Injector). Then, simply turn the nozzle barrel on the end of the wand counterclockwise. As the spray pattern widens, more of the detergent will be drawn through the wand. Turn the nozzle clockwise to reduce the detergent flow and narrow the water spray pattern to return to high pressure.

CHEMICAL INJECTOR – Cat # CMA-1
To use the chemical injector, disconnect the Twist Connect at the output valve on the jet. Then thread the Chemical Injector onto it. The Spray Wand then threads onto the free end of the Chemical Injector. Do not attach the Chemical Injector to the inlet side of the pump. Deter gents can damage the pump.

To use the detergent injector, attach one end of the siphon hose to the barbed fitting on the injector and put the filter end into the detergent solution. Be sure the end of the hose is at the bottom of the container or bucket. Some models have adjustable valves to control the amount of detergent drawn through the hose.

MAINTENANCE

Regular inspection is the key to preventing breakdowns and prolonging the life of the equipment. Follow this simple procedure religiously.

DAILY

• Check the INLET FILTER for debris before each use.
• Check that the PUMP OIL LEVEL is within operating range on the dipstick or sight glass.
• Check that the jet nozzles are not clogged or worn out.

WEEKLY
Check the pressure hose for wear and damage. The damaged hose can be repaired at a local service dealer of by your equipment dealer.

• Pump Crankcase Oil Change: Service after the 1st month, or after 20 hours. Then service every year or 500 hours. Use SAE 30W Non-Detergent Motor Oil to full mark on dipstick or to dot on sight glass.
• Engine Maintenance: Check the engine manual for specific maintenance procedures.
