Set Up

Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this manual including all text under subheadings therein before set up or use of this product.

TO PREVENT SERIOUS INJURY:
Operate only with proper spark arrestor installed.

Operation of this equipment may create sparks that can start fires around dry vegetation.
A spark arrestor may be required. The operator should contact local fire agencies for laws or regulations relating to fire prevention requirements.

High Altitude Operation Above 3000 feet

To prevent serious injury from fire:
Follow instructions 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 proceeding. Do not smoke.

NOTICE
Warranty void if necessary adjustments are not made for high altitude use.

At high altitudes, the engine's carburetor, governor (if so equipped), and any other parts that control the fuel-air ratio will need to be adjusted by a qualified mechanic to allow efficient high-altitude use and to prevent damage to the engine and any other devices used with this product. The fuel system on this engine may be influenced by operation at higher altitudes. Proper operation can be ensured by installing an altitude kit at altitudes higher than 3000 ft. above sea level. At elevations above 8000 ft, the engine may experience decreased performance, even with the proper main jet. Operating this engine without the proper altitude kit installed may increase the engine's emissions and decrease fuel economy and performance. The kit should be installed by a qualified mechanic.

1. Turn off the engine.
2. Close the fuel valve.
3. Place a bowl under the fuel cup to catch any spilled fuel.
   
   Carburetor bowl may have gas in it which will leak upon removing the bolt.
4. Unthread the bolt holding the fuel cup.
5. Remove the bolt, Bolt Seal, fuel cup, Fuel Cup Seal and Main Jet from the body of the carburetor assembly.
   A carburetor screwdriver (not included) is needed to remove and install the Main Jet.
   Note: The mixing tube is held in place by the Main Jet and might fall out when it is removed. If it falls out, replace it in the same orientation before replacing the Main Jet.
6. Replace the Main Jet with the replacement Main Jet needed for your altitude range (part 1a or 2a).
   Note: The Fuel Cup Seal and Bolt Seal may be damaged during removal and should be replaced with the new ones from the kit.
7. Replace the Fuel Cup Seal (4a), fuel cup, Bolt Seal (3a), and bolt. Tighten in place.
   NOTICE: Do not cross thread bolt when tightening. Finger tighten first and then use a wrench to make sure the bolt is properly threaded.
8. 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.

Controls

Connecting Hoses

Note: Hoses not included.
NOTICE: Do not use any reducer on the inlet or discharge port. However, if any reducers were included as part of this pump, they may be used.
Note: The Intake Hose (not included) MUST be reinforced with non-collapsible construction. Match hose diameter to port diameters. Do not reduce hose diameter size.

1. Thread intake hose onto Intake Port.
   NOTICE: Use only a non-collapsible intake hose.
   
2. Slide the Intake Strainer into the end of the intake hose. Tighten until secure.
   
3. Thread discharge hose onto Discharge Port. Tighten until secure.
   

Locating the Water Pump

Locate the Water Pump on a flat, level, sturdy surface capable of supporting the weight of the Pump.

1. For best Pump performance, place the Pump near the water level and use hoses that are no longer than necessary. See diagram below.
   
   
   As the head (pumping height) increases, pump output decreases. A non-collapsible suction hose must be used. The length, type, and size of the suction and discharge hoses can significantly affect Pump output.
   Discharge head capability is always greater than suction head capability. This means pumping height for the Intake Hose (suction head) should be shorter than the pumping height for the Discharge Hose.
   Minimizing suction head (placing the Pump closer to the water level) will also help make it easier to prime the pump (fill it with water).
2. Route the Intake Hose with the Intake Strainer fully immersed in the water supply source.
3. Place Strainer into water to be pumped.
   NOTICE: Immerse strainer fully in water. Do not operate Pump without Strainer connected to end of suction hose. Keep Strainer out of sand or silt by placing Strainer in a bucket or on stones.
   NOTICE: Air leaks must not appear in the suction line. If there is an air leak in the suction line, you will not be able to prime the pump. Use a thread sealant to seal air leaks.
   
   
4. Secure the Intake Hose in place to keep it from moving once the Pump is turned on. The Intake Hose should be as short as possible for more efficient operation.
5. Route the discharge hose to the desired discharge location. If necessary, connect additional discharge hoses to direct the discharge to the desired location. Make sure to secure the discharge hose in place to keep it from moving once the Water Pump is turned on. The discharge hose should be kept as short as possible for more efficient operation.

Operation

Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this manual including all text under subheadings therein before set up or use of this product.

Prime the Pump

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

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.

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.

Checking and Filling Engine Oil

NOTICE: 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. Engine will not start with low or no engine oil.

3. Make sure the engine is stopped and is level.
4. Close the Fuel Valve.
5. Clean the top of the Dipstick and the area around it. Remove the Dipstick by turning it counterclockwise, and wipe it off with a clean, lint free rag.
   
   
6. 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.
7. 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 in the Maintenance section shows other viscosities to use in different average temperatures.)
8. Thread the dipstick back in clockwise.
   NOTICE: Do not run the engine with too little oil. Engine will shut off if engine oil level is too low.

Checking and Filling Fuel
