4. Adding Fuel and Oil
WARNING: Never refuel a hot engine. Allow the engine to cool down before adding fuel or oil.
- Engine Oil: Fill the engine with appropriate 4-stroke engine oil (e.g., SAE 30 or 10W-30) up to the 'FULL' mark on the dipstick. Refer to the engine manual for exact oil capacity.
- Gasoline: Fill the fuel tank with fresh, unleaded gasoline. Do not overfill. Ensure the fuel cap is securely tightened after refueling.
Operating Instructions
1. Starting the Engine
- Ensure the spark plug wire is securely connected.
- Push the primer bulb 3-5 times (if equipped) until fuel is visible in the bulb.
- Move the throttle lever to the "START" or "CHOKE" position.
- Firmly grasp the starter handle and pull the starter rope with a smooth, continuous motion until the engine starts. Do not let the rope snap back.
- Once the engine starts, gradually move the throttle lever to the "RUN" position.
2. Stopping the Engine
To stop the engine, release the engine brake lever (if applicable) or move the throttle lever to the "STOP" position. The engine will shut off automatically.
3. Adjusting Cutting Height
The cutting height can be adjusted using the lever located near the wheels. There are multiple height settings available. Adjust the height to suit your lawn conditions. For best results, avoid cutting more than one-third of the grass blade length at a time.
4. Mowing Techniques
- Mow in overlapping rows to ensure even coverage.
- Avoid mowing wet grass, as it can clog the mower and lead to an uneven cut.
- Always push the mower forward; do not pull it towards you.
- Empty the grass catcher regularly to maintain optimal performance.
Maintenance
WARNING: Always ensure the engine is off and the spark plug wire is disconnected before performing any maintenance.
1. Cleaning
After each use, clean the underside of the mower deck to prevent grass buildup, which can affect cutting performance. Use a stiff brush or scraper. Do not use a high-pressure washer directly on the engine or electrical components.
2. Blade Care
Regularly inspect the cutting blade for sharpness and damage. A dull blade tears grass, leading to an unhealthy lawn. Sharpen or replace the blade as needed. Always use genuine Stanley replacement parts.
3. Spark Plug
Check the spark plug annually or every 25 hours of operation. Clean or replace it if it is fouled or worn. Refer to the engine manual for the correct spark plug type and gap.
4. Oil Change
Change the engine oil after the first 5 hours of operation, and then every 25-50 hours or at least once per mowing season. Refer to the engine manual for the correct procedure and oil type.
5. Storage
For long-term storage (over 30 days):
- Drain the fuel tank or add a fuel stabilizer.
- Change the engine oil.
- Clean the mower thoroughly.
- Store in a clean, dry area, away from direct sunlight and extreme temperatures.
