Pre-Start Checks

Inspect Pump and engine, looking for damaged, loose, and/ or missing parts before set up and starting. If any problems are found, do not use equipment until fixed properly.

Prime the Pump

Checking and Filling Engine Oil

CAUTION! Your Warranty is VOID if the engine’s crankcase is not properly filled with oil before each use. Before each use, check the oil level. Do not run the engine with low or no engine oil. Running the engine with no or low engine oil WILL permanently damage the engine.

1.Make sure the engine is stopped and is level.

2.Close the Fuel Valve.

3.Clean the top of the Dipstick and the area around it. Remove the Dipstick by threading it counterclockwise, and wipe it off with a clean lint free rag.

Before starting the engine, fill the Pump with water. To do this:

Full level

Full level

1.Unthread the Priming Water Filler Cap by turning it counterclockwise.

2.Fill the unit with clean water up to the top of the opening. Replace the Priming Water Filler Cap and tighten securely.

Priming Water

Filler Cap

IMPORTANT! Always check for water in the Pump Housing before each use. Never attempt to run the Water Pump without the Pump Housing FULL of water. Running the Water Pump without water for an extended period of time will damage the Water Pump and void the Warranty.

4.Reinsert the Dipstick without threading it in and remove it to check the oil level. The oil level should be up to the full level as shown above.

5.If the oil level is at or below the low mark add the appropriate type of oil until the oil level is at the proper level. SAE 10W‑30 oil is recommended for general use. (The SAE Viscosity Grade chart on page 12 in the Service section shows other viscosities to use in different average temperatures.)

6.Thread the dipstick back in clockwise.

CAUTION! Do not run the engine with too little oil. The engine will be permanently damaged.

Checking and Filling Fuel

WARNING! To prevent serious injury from fire:

Fill the fuel tank in a well-ventilated area away from ignition sources. If the engine is hot from use, shut the engine off and wait for it to cool before adding fuel. Do not smoke.

1.Clean the Fuel Cap and the area around it.

2.Unscrew and remove the Fuel Cap.

3.If needed, fill the Fuel Tank to about 1″ under the fill neck of the Fuel Tank with 87 octane or higher unleaded gasoline.

Note: Do not use gasoline containing more than 10% ethanol (E10). Do not use E85 ethanol.

Note: Do not use gasoline that has been stored in a metal fuel container or a dirty fuel container. It can cause particles to enter the carburetor, affecting engine performance and/or causing damage.

4.Then replace the Fuel Cap.

5.Wipe up any spilled fuel and allow excess to evaporate before starting engine. To prevent FIRE, do not start the engine while the smell of fuel hangs in the air.
