4. Setup

Before first use, the lawn mower requires some assembly and preparation.

4.1 Handlebar Assembly

1. Unfold the lower handlebar section and secure it with the provided bolts and wing nuts.
2. Attach the upper handlebar section, ensuring the starting cable is routed correctly and not pinched. Secure with the remaining bolts and wing nuts.

4.2 Adding Engine Oil

The engine is supplied without oil. It is crucial to fill the engine with appropriate 4-stroke engine oil before starting. Refer to the engine manual for specific oil type and capacity. Do not overfill.

4.3 Adding Fuel

Use fresh, unleaded petrol (gasoline) with an octane rating of at least 91 RON. Do not use E85 or other ethanol blends not approved for small engines. Fill the fuel tank carefully, avoiding spills. Ensure the fuel cap is securely tightened.

4.4 Initial Checks

• Check that all fasteners are tight.
• Ensure the spark plug wire is securely connected.
• Verify the grass collection bag is correctly attached.

5. Operating

Follow these steps for safe and effective operation of your lawn mower.

5.1 Adjusting Cutting Height

The cutting height can be adjusted to 3 levels (30-60 mm) using the single wheel adjustment mechanism. Ensure the engine is off and the spark plug wire is disconnected before making adjustments. Lift the mower slightly and move the adjustment lever to the desired height setting.

5.2 Starting the Engine

1. Ensure the fuel tank is filled and the oil level is correct.
2. Press the primer bulb (if present) 3-5 times until fuel is visible.
3. Hold the engine brake lever against the handlebar.
4. Pull the starter cord firmly and steadily until the engine starts. Do not let the cord snap back.

5.3 Mowing

Push the mower at a steady pace. For best results, overlap each pass slightly. Avoid mowing wet grass, as it can clog the mower and lead to an uneven cut. The mower is recommended for areas up to 800 m².

5.4 Stopping the Engine

Release the engine brake lever to stop the engine. Wait for all moving parts to come to a complete stop before approaching the mower.

5.5 Emptying the Grass Bag

When the fill-level indicator on the grass bag shows it is full, stop the engine and allow the blade to stop. Carefully remove the grass bag using its two handles and empty the clippings. Reattach the bag securely before resuming operation.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your lawn mower.

6.1 Cleaning

After each use, clean the mower deck and grass bag. Remove grass clippings and debris. Do not use high-pressure water directly on the engine or electrical components.

6.2 Engine Oil Check and Change

Check the engine oil level before each use. Change the engine oil after the first 5 hours of operation, and then every 25 hours or annually, whichever comes first. Refer to the engine manual for detailed instructions.

6.3 Spark Plug Inspection

Inspect the spark plug annually or every 50 hours. Clean or replace if necessary. Ensure the gap is set correctly according to the engine manual.

6.4 Air Filter Cleaning

Clean the air filter regularly, especially in dusty conditions. A dirty air filter can reduce engine performance. Refer to the engine manual for cleaning instructions.

6.5 Blade Inspection

Regularly inspect the cutting blade for sharpness and damage. A dull or damaged blade can lead to poor cutting performance and excessive vibration. Have the blade sharpened or replaced by a qualified service technician if needed.

6.6 Storage

For long-term storage, clean the mower thoroughly. Drain the fuel tank or add a fuel stabilizer. Remove the spark plug and add a small amount of engine oil into the cylinder, then slowly pull the starter cord a few times to distribute the oil. Store the mower in a dry, well-ventilated area. The foldable handlebar allows for compact storage.
