IMPORTANT SAFETY INSTRUCTIONS in upright position or oil may leak from pump. If low, fill with SAE 30 weight non-detergent oil. • Gas jets are shipped with oil in the engine. Consult motor manufac- turer’s guide for oil requirements. • Jet machines are meant to be used at or near the working area and under operator supervision.
• Battery should have lifting strap for easy installation. BUFFER TANK The JM-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 cavatation and damage.

INSTALLATION & PREPARATION 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.

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.
OPERATION 10. When the jet hose encounters a bend, it’s advance will usually slow or stop. The hose has a slight bend in 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.

OPERATION attach a short garden hose (not to exceed four feet) to inlet on the pump and put 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.
