Operation 100743 - 3 in. (7.5 cm) Semi-Trash Pump EMPTY NOTICE FULL Our engines work well with 10% or less ethanol blend gasoline. When using ethanol-gasoline blends there are some issues worth noting: – Ethanol-gasoline blends can absorb more water than gasoline alone. – These blends can eventually separate, leaving water or a watery goo in the tank, fuel valve and carburetor.
Operation 100743 - 3 in. (7.5 cm) Semi-Trash Pump DANGER Total head Using an engine indoors CAN KILL YOU IN MINUTES. Engine exhaust contains carbon monoxide. This is a poison you cannot see or smell. Discharge head Suction head NEVER use inside a home or garage, EVEN IF doors and windows are open. ONLY use OUTSIDE and far away from windows, doors, and vents. Connecting a Hose Kit NOTICE Both the inlet and outlet ports are 3 in. (7.5 cm) NPT.
Operation 100743 - 3 in. (7.5 cm) Semi-Trash Pump 3. Locate and slide the silver colored hose clamp (marked 7479) over the blue outlet hose. 5. Slide the hose clamp in place about midway on the outlet hose adapter as shown. Tighten to 7.4±1.5 lbf-ft (10±2 Nm) with a 13mm wrench. The hose clamp should be placed behind the outlet adapter barbs on the smooth part of the adapter. 4. Slide the blue discharge hose over the outlet hose fitting. Connect the Suction Hose (Green) and Suction Filter 1.
Operation 100743 - 3 in. (7.5 cm) Semi-Trash Pump 3. Separate the cam lock coupler and fitting. Align the green hose to the coupler and mark the locations of the ribs on the fitting. 7. Insert the threaded or quick coupler in the green rigid suction hose until properly seated. NOTICE 4. Mark the second rib on the coupler on the hose. You may use a small amount of dish soap on the cam lock coupler to help ease the green hose on the fitting. Work the soap around the coupler with your finger.
Operation 100743 - 3 in. (7.5 cm) Semi-Trash Pump 10. Tighten each clamp to 7.4±1.5 lbf-ft (10±2 Nm) with a 13mm wrench. If you do not have a torque wrench, hand tight then ¼ turn past full tight. 14. Attach the cam lock coupler to the fitting. 15. Lock in place with the cam levers. 11. Test connection is tight by twisting coupler in the hose to make sure it doesn’t turn. If coupling turns, then tighten clamps further until coupling won’t turn.
Operation 100743 - 3 in. (7.5 cm) Semi-Trash Pump 18. Place the clamp marked 80-85 on the other end of the green hose. Attach the strainer to the green suction hose. 21. You should have everything connected. Priming the Pump NOTICE NOTICE You may use a small amount of dish soap on the filter to help ease the green hose on the filter.

Operation 100743 - 3 in. (7.5 cm) Semi-Trash Pump Before Starting the Engine NOTICE 1. Route the suction hose so that the filter is immersed completely in the water supply source. Keep choke lever in “CHOKE” position for 2 pulls of the recoil starter. After second pull, move choke lever to the “RUN” position for up to the next 3 pulls of the recoil starter. Too much choke leads to spark plug fouling/engine flooding due to the lack of incoming air. This will cause the engine not to start. 2.
Operation 100743 - 3 in. (7.5 cm) Semi-Trash Pump 2. Let the engine run until fuel starvation has stopped the engine. This usually takes a few minutes. WARNING Rapid retraction of the recoil cord will pull hand and arm towards the engine faster than you can let go. Unintentional startup can result in entanglement, traumatic amputation or laceration. Broken bones, fractures, bruises or sprains could result. 3. Press the engine switch to the “OFF” position. 7.
Maintenance 100743 - 3 in. (7.5 cm) Semi-Trash Pump 4. Inspect all air vents and cooling slots to ensure that they are clean and unobstructed. WARNING Operation using the alternative main jet at elevations lower than the recommended minimum altitude can damage the engine. For operation at lower elevations, the originally supplied standard main jet must be used.
Maintenance 100743 - 3 in. (7.5 cm) Semi-Trash Pump Cleaning and Adjusting the Spark Plug(s) 2. Remove the foam element. 3. Wash the foam element in liquid detergent and water.
