Operating Instructions

Follow these steps for safe and effective operation of your lawnmower.

1. Adjust Cutting Height: The lawnmower features a central cutting height adjustment with 5 steps, ranging from 25 mm to 70 mm. Locate the adjustment lever and set it to your desired cutting height before starting the engine.
2. Starting the Engine:
   • Ensure the spark plug lead is securely connected.
   • Prime the engine if necessary (refer to engine manual).
   • Engage the safety bail lever on the handle.
   • Pull the starter cord firmly until the engine starts. The Magnetron electronic ignition system facilitates a quick start.
3. Mowing:
   • The PLM4621N2 is equipped with a 1-speed wheel drive, assisting in comfortable maneuvering across your lawn.
   • Mow in overlapping rows to ensure an even cut.
   • Avoid mowing wet grass, as it can clog the mower and lead to an uneven cut.
4. Mulching (Optional): A mulching kit is included with the mower. To mulch, remove the grass collection bag and insert the mulching plug into the discharge chute. This allows the grass clippings to be finely cut and returned to the lawn as natural fertilizer.
5. Stopping the Engine: Release the safety bail lever to stop the engine. Allow the blade to come to a complete stop before approaching the mower.

Maintenance

Regular maintenance ensures the longevity and optimal performance of your Makita lawnmower.

• Cleaning: After each use, clean the underside of the mower deck to prevent grass buildup. Use a brush or scraper. Do not use high-pressure water directly on the engine.
• Blade Care: Regularly inspect the cutting blade for sharpness and damage. A dull blade can tear grass, leading to an unhealthy lawn. Sharpen or replace the blade as needed. Always disconnect the spark plug before handling the blade.
• Engine Oil: Check the engine oil level before each use. Change the engine oil periodically as recommended in the engine manual, typically after the first 5 hours and then every 25-50 hours of operation.
• Air Filter: Clean or replace the air filter regularly, especially when operating in dusty conditions. A clogged air filter can reduce engine performance.
• Spark Plug: Inspect and clean the spark plug annually or as recommended. Replace if worn or fouled.
• Storage: For long-term storage, drain the fuel tank or add a fuel stabilizer. Clean the mower thoroughly and store it in a dry, protected area.
