2. Handlebar Assembly

Attach the handlebar to the mower body. Secure it using the provided quick clamps. Ensure the clamps are tightened securely to prevent movement during operation. Note: Some users have reported issues with plastic clamp durability; ensure proper alignment and avoid over-tightening. The ergonomic handlebar is fully foldable for easy storage.

3. Battery Installation and Charging (for Electric Start)

The Briggs & Stratton 475IS Series engine features an electric start system powered by a Lithium-ion battery. Locate the battery compartment and insert the fully charged battery. Ensure the battery is charged before first use. Refer to the separate battery charger manual for charging instructions.

4. Fuel and Oil Filling

Fill the fuel tank with fresh, unleaded gasoline. Check the engine oil level and fill with the recommended engine oil (refer to the engine manual for specific oil type and capacity). Do not overfill.

5. Adjusting Cutting Height

The cutting height is centrally adjustable with a single lever, offering 7 positions from 25mm to 75mm. Select the desired cutting height by moving the lever. For best results, avoid cutting more than one-third of the grass blade length at a time.

6. Attaching the Grass Collection Bag

Attach the 55-liter hybrid grass collection bag to the rear of the mower. Ensure it is securely fitted. The bag features a fill indicator. The front comb allows for better airflow and grass collection.

Operating

1. Starting the Engine

Ensure the fuel tank is filled and the oil level is correct. Press the electric start button to engage the engine. If the engine does not start immediately, wait a few seconds and try again. For cold starts, it may require 2-3 attempts.

2. Engaging Self-Propelled Drive

To engage the self-propelled function, squeeze the drive lever on the handlebar. Release the lever to disengage the drive.

3. Mowing Techniques

Mow in overlapping rows for an even cut. For best results, mow when the grass is dry. Avoid sudden turns and maintain a steady pace. The mower is designed for efficient grass collection and mulching.

4. Mulching Function

The mulching kit allows you to finely cut grass clippings and redistribute them onto the lawn. This returns nutrients to the soil, promoting healthier grass. To activate mulching, ensure the grass collection bag is removed and the mulching plug (if separate) is installed.

5. Stopping the Engine

Release the engine brake lever (typically located on the handlebar) to stop the engine. Wait for all moving parts to come to a complete stop before approaching the mower.

Maintenance

Regular maintenance ensures optimal performance and extends the life of your lawn mower. Always disconnect the spark plug wire before performing any maintenance.

• Cleaning: After each use, clean the underside of the mower deck to prevent grass buildup. Clean the exterior with a damp cloth. Do not use a high-pressure washer directly on the engine or electrical components.
• Blade Care: Inspect the blade regularly for sharpness and damage. A dull blade can tear grass, leading to an unhealthy lawn. Sharpen or replace the blade as needed.
• Engine Maintenance:
  • Oil Change: Change the engine oil according to the schedule in the Briggs & Stratton engine manual.
  • Air Filter: Clean or replace the air filter regularly to ensure proper engine breathing.
  • Spark Plug: Inspect and clean the spark plug periodically. Replace if worn.
• Grass Bag: Empty the grass bag frequently, especially when the fill indicator shows it's full, to maintain efficient collection and prevent clogging.
• Storage: Before storing for extended periods, ensure the fuel tank is empty or treated with a fuel stabilizer. Clean the mower thoroughly. Store in a dry, protected area with the handlebar folded for compactness.
