JM-3080™ Gas Jet Operating Instructions Your JM-3080 Jet-Set gas-powered water jet is designed to give you years of trouble-free, profitable service. However, no machine is better than its operator. Read, understand and follow all safety warnings and instructions provided with the product. Failure to follow the warnings and instructions may result in electric shock and/or serious injury. Save all warnings and instructions for future reference.
Jet-Set JM-3080™ Serious injury or death may occur from inhaling engine exhaust or dangerous vapors. Use this product only in a well ventilated area. This water jet is designed for outdoor use only. Always make sure there is adequate ventilation (fresh outside air) for breathing and combustion. WARNING! Read and understand all instructions. Failure to follow all instructions listed below may result in electric shock, fire and/or serious personal injury.
Jet-Set JM-3080™ GENERAL SAFETY RULES JET SAFETY 1. Do not operate jet above rated pressure or above 140 degrees (rated water temperature). Operating jet above rate specifications risks damage to the pump and related components, and will void the warranty. 2. Do not operate jet with the output valve in the off position for extensive periods of time. This will cause the water to overheat and damage the pump. 3. Never run pump without water in it.
Jet-Set JM-3080™ 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. 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.

JET ASSEMBLY 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.
Jet-Set JM-3080™ SPECIAL APPLICATIONS OPERATION CONTINUED 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.
Jet-Set JM-3080™ The Spray Wand can be used to clean your truck or other applications. Caution: Never clean the machine with its own 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 connect 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.
Jet-Set JM-3080™ TROUBLE SHOOTING GUIDE Problem Probable Cause Solution Low pressure. Worn, clogged, or oversized nozzle. Clean or replace worn nozzle. Check nozzle size. Clogged water inlet strainer. Clean or replace strainers. Inadequate water supply. Make certain water supply valve is on fully. Make certain water supply hose is at least 3/4” in diameter, in good condition, with no kinks or damage, and is not longer than 50 ft. Worn or damaged piston cups. Replace piston cups.
Jet-Set JM-3080™ TROUBLE SHOOTING GUIDE continued Problem Probable Cause Solution Washer fails to draw detergent. Detergent metering valve closed, or valve clogged or defective. Open detergent metering valve, following procedure in operating instructions. Back pressure in hose (when using additional lengths of pressure hose). Contact dealer for proper injector size when adding lengths of hose. Back pressure in pressure hose (when using dual lance wand).
