Essential Maintenance Tasks and Schedules
The following tasks should be performed regularly to keep your Briggs & Stratton pressure washer engine in top condition. Consult your owner's manual for specific recommendations for your model.
1. Oil Changes:
- Why it's important: Oil lubricates the engine's internal components, reducing friction and wear. Over time, oil breaks down, becomes contaminated with dirt and debris, and loses its lubricating properties.
- First Oil Change: After the first 5 hours of operation. This is critical for removing metal shavings and other contaminants from the manufacturing process.
- Subsequent Oil Changes: Every 25-50 hours of operation, or at least once a year, whichever comes first. If you use your pressure washer frequently or in harsh conditions (dusty environments, high temperatures), change the oil more often.
- Procedure:
- Gather Supplies: Fresh oil (refer to your owner's manual for the correct type and weight), oil filter (if applicable), oil drain pan, wrench for removing the drain plug, rags or paper towels, funnel.
- Warm Up the Engine: Run the engine for a few minutes to warm the oil, making it flow more easily. Do not run it for too long, as the oil will become too hot to handle.
- Disconnect the Spark Plug Wire: This prevents accidental starting during the oil change.
- Locate and Remove the Drain Plug: The drain plug is usually located on the bottom of the engine. Place the drain pan underneath to catch the oil. Use the wrench to remove the plug.
Allow the Oil to Drain Completely: This may take 15-30 minutes. - Replace the Drain Plug: Once the oil is drained, reinstall the drain plug and tighten it securely. Do not overtighten.
- Replace the Oil Filter (if applicable): Unscrew the old oil filter and lightly lubricate the rubber gasket of the new filter with fresh oil. Screw the new filter onto the engine by hand until the gasket makes contact, then tighten it another half to three-quarters of a turn.
- Add Fresh Oil: Refer to your owner's manual for the correct oil capacity. Use a funnel to pour the oil into the oil fill port.
- Check the Oil Level: Use the dipstick to check the oil level. Add more oil if necessary until it reaches the "full" mark. Do not overfill.
- Reconnect the Spark Plug Wire.
- Dispose of the Used Oil Properly: Take it to a recycling center or auto parts store. Do not pour it down the drain or into the ground.
2. Air Filter Maintenance:
- Why it's important: The air filter prevents dirt and debris from entering the engine, which can cause wear and damage. A clogged air filter restricts airflow, reducing engine performance and fuel efficiency.
- Inspect: Every 5 hours of operation.
- Clean: Every 25 hours of operation, or more frequently in dusty conditions.
- Replace: Every 100 hours of operation, or annually.
- Procedure:
- Locate the Air Filter Housing: This is usually a plastic cover located on the side or top of the engine.
- Remove the Air Filter Cover: This usually involves unscrewing a few screws or releasing a clip.
- Remove the Air Filter: Carefully remove the air filter, noting its orientation.
- Clean the Air Filter (if applicable):
- Foam Filters: Wash the filter in warm soapy water. Rinse thoroughly and allow it to dry completely. Apply a light coating of air filter oil.
- Paper Filters: Tap the filter gently on a hard surface to remove loose dirt. Do not wash paper filters. If the filter is heavily soiled or damaged, replace it.
- Clean the Air Filter Housing: Wipe out the inside of the air filter housing with a clean cloth.
- Reinstall the Air Filter: Make sure the filter is properly seated in the housing.
- Reinstall the Air Filter Cover.
3. Spark Plug Maintenance:
- Why it's important: The spark plug ignites the air-fuel mixture in the engine's cylinder, initiating the combustion process. A fouled or worn spark plug can cause starting problems, misfires, and reduced engine performance.
- Inspect and Clean: Every 100 hours of operation, or annually.
- Replace: Every 200-300 hours of operation, or every 2 years.
- Procedure:
- Disconnect the Spark Plug Wire: This prevents accidental starting.
- Locate the Spark Plug: This is a small, hexagonal-shaped component protruding from the engine's cylinder head.
- Remove the Spark Plug: Use a spark plug wrench to unscrew the spark plug.
- Inspect the Spark Plug: Look for signs of wear, damage, or fouling (carbon buildup).
- Clean the Spark Plug (if applicable): Use a wire brush to clean the spark plug electrodes.
- Check the Spark Plug Gap: Use a spark plug gap tool to ensure the gap between the electrodes is within the specification recommended in your owner's manual. Adjust the gap if necessary by gently bending the ground electrode.
- Reinstall the Spark Plug: Screw the spark plug into the cylinder head by hand until it is snug. Then, use the spark plug wrench to tighten it another half to three-quarters of a turn. Do not overtighten.
- Reconnect the Spark Plug Wire.
4. Fuel System Maintenance:
- Why it's important: Fresh, clean fuel is essential for proper engine performance. Stale fuel can gum up the carburetor and fuel lines, leading to starting problems and reduced power.
- Use Fresh Fuel: Use fuel that is less than 30 days old.
- Add Fuel Stabilizer: If you plan to store your pressure washer for an extended period (more than 30 days), add fuel stabilizer to the fuel tank. This will prevent the fuel from breaking down and forming deposits.
- Drain the Fuel Tank: Before storing your pressure washer for the winter, drain the fuel tank completely. This will prevent fuel-related problems during the off-season.
- Clean the Carburetor (if necessary): If your engine is experiencing starting problems or running poorly, the carburetor may need to be cleaned. This is a more complex procedure and may require the assistance of a qualified technician.
- Procedure (Fuel Stabilizer):
- Add the correct amount of fuel stabilizer to the fuel tank according to the manufacturer's instructions.
- Run the engine for a few minutes to allow the stabilized fuel to circulate through the fuel system.
- Procedure (Draining the Fuel Tank):
- Locate the fuel shut-off valve (if equipped) and turn it to the "off" position.
- Disconnect the fuel line from the carburetor.
- Place a container underneath the fuel line to catch the fuel.
- Open the fuel shut-off valve (if equipped) and allow the fuel to drain completely.
- Reattach the fuel line to the carburetor.
5. General Inspection and Cleaning:
- Why it's important: Regular inspection and cleaning can help you identify and address potential problems before they become serious.
- Frequency: Before each use.
- Procedure:
- Inspect for Leaks: Check for fuel or oil leaks around the engine.
- Clean the Engine: Wipe down the engine with a clean cloth to remove dirt and debris.
- Check the Hoses and Fittings: Inspect the hoses and fittings for cracks, leaks, or damage.
- Check the High-Pressure Hose: Inspect the high-pressure hose for kinks, cuts, or bulges. Replace the hose if it is damaged.
- Check the Nozzles: Clean the nozzles with a nozzle cleaning tool to remove any clogs.
6. Winterizing Your Pressure Washer:
- Why it's important: Protecting your pressure washer from freezing temperatures is crucial to prevent damage to the pump and other components.
- Procedure:
- Drain the Water: Disconnect the high-pressure hose and spray gun and drain all the water from the pump and hoses.
- Add Pump Protector: Add pump protector to the pump to prevent freezing and corrosion. Follow the manufacturer's instructions.
- Store in a Dry Place: Store the pressure washer in a dry, protected location, such as a garage or shed.
