3. Setup and Assembly
The Scheppach BMS196-88 requires some assembly before first use. Follow these steps carefully.
3.1 Unpacking
Carefully remove all components from the packaging. Check for any damage during transit and ensure all parts are present according to the packing list.
3.2 Handlebar Assembly
Attach the handlebar to the main unit. Ensure all bolts are securely tightened. The handlebar is adjustable in 3 heights for ergonomic working.
3.3 Wheel Installation
Install the large wheels with off-road profile. This step may require patience due to tight clearances. Ensure wheels are securely fastened for optimal traction.
3.4 Initial Fluid Checks

4. Operating Instructions
4.1 Starting the Engine
The mower is equipped with a pull starter. Follow the engine manufacturer's instructions for starting, typically involving setting the choke, engaging the throttle, and pulling the starter cord firmly.

4.2 Adjusting Cutting Height
The cutting height can be adjusted from 30 mm to 60 mm. Adjust the height according to the grass type and desired finish. For very high grass, it is recommended to make multiple passes, gradually lowering the cutting height.

5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your scythe mower.
5.1 Cleaning
After each use, clean the cutting bar and the underside of the machine to remove grass clippings and debris. This prevents corrosion and maintains cutting efficiency. Use a brush or compressed air; avoid using high-pressure water directly on the engine or electrical components.
5.2 Blade Care
Inspect the cutting blades regularly for sharpness and damage. Dull or damaged blades can lead to poor cutting performance and increased strain on the engine. Sharpen or replace blades as needed. Always wear heavy-duty gloves when handling blades.
5.3 Engine Maintenance
Refer to the engine manual for detailed maintenance schedules. This typically includes:
- Checking and changing engine oil.
- Cleaning or replacing the air filter.
- Inspecting and cleaning the spark plug.
- Checking the fuel filter.

5.4 Storage
When storing the mower for extended periods, especially during off-season, ensure the fuel tank is empty or treated with a fuel stabilizer. Clean the machine thoroughly and store it in a dry, protected area.
