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. Safety Pre-Start Checks Inspect engine and equipment looking for damaged, loose, and missing parts before set up and starting. If any problems are found, do not use equipment until fixed properly. Checking and Filling Engine Oil 1. Make sure the engine is stopped and is level. 2. Close the Fuel Valve. 3.
Checking Pump Oil Level 1. The Oil pump is filled with 3.75 fl-oz of SAE 10W-30 NON DETERGENT oil at the factory. Under normal conditions there is no reason to add any oil or change the oil. Safety 2. Turn off engine, allow it to cool and disconnect the spark plug wire. 3. Twist the Dipstick on the Pump Breather Plug until the arrow on it lines up with the arrow on the Plug and remove the Dipstick. 4. Remove the Pump Breather Plug from the Pump.
Starting the Engine 1. To start a cold engine, move the Choke to the CHOKE position. To restart a warm engine, leave the Choke in the RUN position. Safety 1 Choke RUN 2. Open the Fuel Valve. Setup 2 3. Slide the Throttle or Speed Control Lever to 1/3 away from the SLOW position (the “turtle”). 3 Note: Some tools have a Speed Control Lever located elsewhere on the tool which functions the same as the Throttle. Use the Speed Control Lever in place of the Throttle when the tool is so equipped. 4.
IMPORTANT: Allow the engine to run at no load for five minutes with no load after each start‑up so that the engine can stabilize. 7. Adjust the Throttle as needed. 8. Break-in Period: Safety a. Breaking-in the engine will help to ensure proper equipment and engine operation. b. 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. c.
Pressure Washer Operation Do not direct spray from the pressure washer at a person or an animal. The water stream could cause serious injury. Caution Use the pressure washer only on surfaces able to withstand the force of the spray. 3. 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. 4. Turn the water supply on and hold down the Trigger to start the stream.
Maintenance WARNING Safety To prevent serious injury from accidental starting: Turn the Power Switch of the equipment to its “OFF” position, wait for the engine to cool, and disconnect the spark plug cap before performing any inspection, maintenance, or cleaning procedures. To prevent serious injury from equipment failure: Do not use damaged equipment. If abnormal noise, vibration, or excess smoking occurs, have the problem corrected before further use. Follow all service instructions in this manual.
Checking and Filling Fuel 1. Clean the Fuel Cap and the area around it. 2. Unscrew and remove the Fuel Cap. 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.
Air Filter Element Maintenance 1. Remove the air filter cover and the air filter elements and check for dirt. Clean or replace as described below. Safety 2. Cleaning: • For “paper” filter elements: To prevent injury from dust and debris, wear ANSI-approved safety goggles, NIOSH‑approved dust mask/respirator, and heavy-duty work gloves. In a well‑ventilated area away from bystanders, use pressurized air to blow dust out of the air filter. If this does not get the filter clean, replace it.
Storage 2. FUEL: WARNING! To prevent serious injury from fire: Drain 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 draining fuel. Do not smoke. a. Place a funnel leading to a proper gasoline container below the carburetor. Sediment Cup (some engines) Drain Plug b. Remove the drain bolt from the bottom of the carburetor bowl and allow the fuel to drain. b. Clean out area around spark plug.
Troubleshooting Problem Engine will not start Safety Setup Operation Engine misfires Possible Causes Probable Solutions Maintenance Fuel Related: Fuel Related: 1.
