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 in the Maintenance section shows other viscosities to use in different average temperatures.)
6. 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

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. Remove the Strainer and remove any dirt and debris. Then replace the Strainer.
   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. If needed, fill the Fuel Tank to about 1 inch under the fill neck of the Fuel Tank with 87 octane or higher unleaded gasoline that has been treated with a fuel stabilizer additive. Follow fuel stabilizer manufacturer's recommendations for use.
5. Then replace the Fuel Cap.
6. 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.

Starting the Engine

Before Starting the Engine

1. 
   Inspect the equipment and engine.
2. Fill the engine with the proper amount and type of both stabilizer-treated unleaded gasoline and oil.
3. TURN ON WATER SUPPLY, REMOVE NOZZLE, POINT WAND IN SAFE DIRECTION, AND HOLD DOWN TRIGGER UNTIL ALL AIR IS RELEASED FROM THE SYSTEM, AT LEAST 30 SECONDS. Then release the Trigger, lock it in the safety position and replace Nozzle before starting engine.

Manual Start

1. To start a cold engine, move the Choke to the START position. To restart a warm engine, leave the Choke in the RUN position.
   
2. Open the Fuel Valve.
   
3. Turn the Engine Switch on.
   Note: If engine does not start, check engine oil level. Engine will not start with low or no engine oil.
   
4. Grip the Starter Handle of the Engine loosely and pull it slowly two times to allow the gasoline to flow into the Engine's carburetor. Then pull the Starter Handle gently until resistance is felt. Allow Cable to retract fully and then pull it quickly. Repeat until the engine starts.
   Note: Do not let the Starter Handle snap back against the engine. Hold it as it recoils so it doesn't hit the engine.
   
5. Allow the Engine to run for several seconds. Then, if the Choke lever is in the START position, move the Choke Lever very slowly to its RUN position.
   Note: Moving the Choke Lever too fast could stall the engine.
   

Break-in Period:

1. Breaking-in the engine will help to ensure proper equipment and engine operation.
2. The operational break-in period will last about 3 hours of use. During this period:
   • Do not apply a heavy load to the equipment.
   • Do not operate the engine at its maximum speed.
3. The maintenance break-in period will last about 20 hours of use.
   • Change the engine oil after this period.
     Under normal operating conditions subsequent maintenance follows the schedule explained in the MAINTENANCE section.

Pressure Washer Operation

Do not direct spray from the Pressure Washer at a person or an animal.
The water stream could cause serious injury.

Use the Pressure Washer only on surfaces able to withstand the force of the spray.

1. Choose the Nozzle that best meets the needs of the job. See Chart below. Only use the Nozzles on surfaces capable of withstanding the force of the spray. Only use the Black Nozzle when using pressure washer detergent. The power of the other Nozzles will propel mist back at the operator and can embed detergent into the surface.

2. Pull back the quick connect collar and push the Nozzle onto the end of the Wand. Make sure the quick connect collar locks the Nozzle in place.
   If using detergent: Read detergent directions. Only use detergents specified for use with pressure washers. Open the Detergent Tank Lid, fill Detergent Tank with prepared detergent solution and close the Lid. The Pressure Washer will draw one gallon of detergent for every seven gallons of water. Only use the Black (low pressure) Nozzle when spraying detergents.
3. With water supply on and Engine running following directions in Starting the Engine, unlock and hold down the Trigger to start the stream. Be aware that when it is first started, the gun will kick.
4. Start with a low pressure Nozzle, and gradually use higher pressures as needed. Test spray the edge of the surface to be cleaned first to make sure that the stream is not too strong for the surface. If the stream damages the surface, move further away from the surface being cleaned to reduce the pressure being applied to the surface. If the stream is still too strong, lock the Trigger in the safety position and change to a lower pressure Nozzle.
5. Hold the Wand at about a 45° angle when cleaning; spraying the surface directly could embed dirt into the surface (especially with the high pressure Nozzles). Spray at a distance of about three to five feet.
6. Clean vertical and sloped surfaces from the top down.
7. When cleaning horizontal surfaces, occasionally use the stream to clear the area of excess water.
   
   Do not allow the Pressure Washer to idle without the Trigger held down for more than two minutes. The water will heat up and damage the Pressure Washer. RISK OF BURNS! The Pump will expel very hot water if allowed to idle too long.
   Note: During normal operation the Thermal Relief Valve may release small amounts of water intermittently.
8. Hold the Trigger down and move the Wand back and forth slowly and steadily to pressure wash the surface. Take special care when spraying surfaces made of two different materials (brick and mortar, for example), so as to not damage the softer of the two materials during pressure washing.
9. If the surface is streaked or uneven at the end of a job, switch to a Nozzle that has a wider spray pattern to blend the affected area.

Stopping the Engine and Pressure Washer

1. To stop the engine in an emergency, turn the Engine Switch off.
   
2. Under normal conditions, use the following procedure:
   1. Release the Trigger on the Spray Gun handle.
   2. Turn the Engine Switch off.
   3. Close the Fuel Valve.
   4. Turn the water supply off.
3. Squeeze the Trigger to release excess pressure.
   
4. If pressure washer detergent has been used, run clean water through the system to eliminate detergent residue using the following procedure:
   1. Turn off the Engine as detailed in step 2.
   2. Fill the Detergent Tank with clean water.
   3. Remove the Nozzle and restart the Engine following directions in Starting the Engine.
   4. Point Wand in safe direction and hold down Trigger to flush water through system until clean.
   5. Turn off the Engine as detailed in step 2.
