Overview

The JM-3080 Gas Jet is a powerful, gas-powered water jet designed for drain cleaning. It is built for outdoor use in well-ventilated areas, emphasizing safety and efficient operation.

Function Description:

The JM-3080 Jet-Set is primarily used for clearing clogs and cleaning the interior walls of pipes. It operates by generating a high-pressure stream of water, which can be directed through a jet hose and various nozzles into drain lines. The machine is equipped with a removable hose reel for remote operation, allowing the main unit to remain in a safe, well-ventilated area while the hose is guided into the drain. A key feature is the Vibra-Pulse® system, which causes the hose to vibrate, helping it navigate longer distances and around tight bends in the pipe, making the jet more effective. The machine can also be used for general pressure washing with an optional spray wand and can draw detergent through a chemical injector for enhanced cleaning. It is designed to handle various pipe sizes and types of blockages, including grease, ice, and roots, with different nozzles available for specific tasks.

Important Technical Specifications:

  • Buffer Tank: 12-gallon capacity. This tank protects the pump from cavitation and damage if the incoming water flow is less than the 8 GPM required by the pump. It allows the jet to run for approximately 8 minutes before needing to refill.
  • Pressure: The pump operates at 3000 psi. It is crucial not to exceed this rated pressure or a water temperature of 140°F (60°C) to prevent damage and voiding the warranty.
  • Hose Reel: 400 ft. hose reel, which is removable for remote operation.
  • Battery: Requires a Lawn Tractor Battery (175 CCA). The battery box size is 8 1/2" L x 6" W x 6 1/4" H.
  • Water Supply: Requires a minimum water supply of 20 psi and not to exceed 100 psi. The water temperature should not exceed 140°F (60°C). Heavy-duty 3/4" hose, no more than 50 ft. in length, is recommended for the water supply.
  • Nozzle Orifice: Specific nozzle orifices are required for the 3000 psi pump to ensure proper pressure and avoid damage.
  • Engine: Gas-powered engine (specific model details like 670cc Rewind GPC or MITM are mentioned in the parts list, but not in the general specifications).

Usage Features:

  • Removable Hose Reel: Allows for remote operation, enabling the main unit to be positioned safely while the hose is used in confined or elevated spaces (e.g., roofs for vent cleaning).
  • Vibra-Pulse® System: Enhances hose navigation through drains by creating vibrations, reducing friction and making it easier to clear tight bends. Most effective with 1/8" hoses.
  • Nozzle Variety: A range of jet nozzles is available for different applications:
    • Thruster Nozzle (JN-101/JN-111): General purpose.
    • Flusher Nozzle (JN-102/JN-112): Wide spray for flushing and cleaning pipe walls.
    • High Thrust Degreaser Nozzle (JN-103/JN-113): Designed for cutting through grease.
    • Monster Nozzle (JN-104/JN-114): For heavy-duty cleaning.
    • Rotary Nozzles (JNRB-7/JNRB-11): Useful as a finishing tool for thoroughly cleaning pipe walls after a clog is cleared, best for straight runs.
    • Chain Saw Nozzles (JCSN-11): Spin at up to 10,000 rpm to rip through roots, with interchangeable chains for different pipe diameters.
  • Hose Selection Guide: Provides recommendations for hose size (ID*) based on pipe size and typical applications (e.g., 3/8" hose for 4"-8" floor drains/septic lines, 1/4" hose for 2"-4" kitchen sinks/laundry drains).
  • Adjusting Pressure Unloader: A regulating pressure unloader prevents pressure overload if the nozzle is clogged or the output valve is off. It allows for adjustment of pressure.
  • Thermal Overload Protection: Releases hot water and allows cool water to enter the pump if the water temperature in the pump increases to 140°F (60°C).
  • Optional Accessories:
    • Handy-Reel with Foot Pedal (HM-200-W): Combines the removable reel with a foot pedal for hands-free operation, interrupting water flow between pump and nozzle.
    • Foot Pedal Only (FM-1): Provides hands-free control of water flow, allowing the operator to guide the hose.
    • Spray Wand (SWA-3080): For general pressure washing applications.
    • Chemical Injector (CMA-1): Allows the machine to draw soap for detergent cleaning.

Maintenance Features:

  • Daily Inspection:
    • Check INLET FILTER for debris.
    • Check PUMP OIL LEVEL on dipstick or sight glass.
    • Check jet nozzles for clogs or wear.
  • Weekly Inspection:
    • Check pressure hose for wear and damage. Damaged hoses can be repaired by a service dealer.
  • Pump Crankcase Oil Change: Service after the first month or 20 hours, then annually or every 500 hours. Use SAE 30W Non-Detergent Motor Oil.
  • Engine Maintenance: Refer to the engine manual for specific procedures.
  • Freeze Protection (Winterization): Essential to protect the machine from freezing damage. Involves flushing the system with anti-freeze or using compressed air to clear residual water from hoses.
  • Troubleshooting Guide: Comprehensive guide for common problems, probable causes, and solutions, covering issues like low pressure, rough operation, water/oil leaks, excessive wear, and detergent drawing failures.
  • Replacement Kits: Specific kits are available for common wear parts, including valves, water seals, oil seals, piston guides, and pistons.
