3. Setup and Assembly
The Einhell GC-HM 300 requires minimal assembly. Follow these steps to prepare your lawn mower for use:
- Handlebar Assembly: Attach the handlebar sections to the main body of the mower using the provided hardware. Ensure all bolts are tightened securely. The curved handlebar is designed for optimal ergonomics.

4. Operating Instructions
Operating your Einhell GC-HM 300 is straightforward. Follow these guidelines for effective mowing:
4.1. Cutting Height Adjustment
The cutting height can be adjusted individually in 4 levels, ranging from 13 mm to 37 mm. Locate the height adjustment mechanism, typically near the wheels or cutting cylinder, and select your desired cutting height. A higher setting is recommended for the first cut of the season or for very long grass.
4.2. Mowing Technique
- Push the mower forward at a steady, comfortable pace. The ball-bearing cutting cylinder with 5 high-performance steel blades will rotate as the wheels turn, cleanly cutting the grass.
- Overlap each pass slightly to ensure an even cut across the entire lawn.
- For best results, mow when the grass is dry. Avoid mowing wet grass, as it can clog the blades and collection box.
- Empty the grass collection box regularly to maintain optimal performance and prevent blockages.

5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your Einhell GC-HM 300 manual lawn mower.
5.1. Cleaning
- After each use, clean grass clippings from the cutting cylinder, blades, and wheels. Use a stiff brush or a damp cloth.
- Ensure the grass collection box is emptied and cleaned regularly.
- Do not use high-pressure washers directly on the bearings or cutting mechanism.
5.2. Blade Care
The 5 high-performance steel blades are designed for durability. If you notice a decrease in cutting efficiency, the blades may require sharpening. It is recommended to have this done by a qualified service technician to ensure proper balance and sharpness.
5.3. Storage
When not in use, store the lawn mower in a dry, protected area. The parking position allows for simple and safe storage, minimizing the space required.
