3. Setup and Assembly
Your lawn mower may require some assembly before first use. Follow these steps carefully.
3.1 Handle Assembly
Unfold the handle and secure it using the provided knobs and bolts. Ensure all connections are tight and the handle is stable.
3.2 Adding Engine Oil
The engine is shipped without oil. Before starting, fill the engine with the recommended type and amount of oil. Refer to the engine manual for specific oil requirements and capacity. Do not overfill.
3.3 Adding Fuel
Fill the fuel tank with fresh, unleaded gasoline. Do not use E85 or other ethanol blends not approved for small engines. Ensure the fuel cap is securely tightened after refueling.
3.4 Attaching the Grass Collection Box
Assemble the 65-liter grass collection box according to its separate instructions, then attach it securely to the rear discharge opening of the mower.
3.5 Front Wheel Locking Lever
The front wheel features a locking lever for stability. For general mowing, the wheel can swivel freely. For straight-line mowing or on slopes, engage the locking lever to fix the front wheel's direction.

4. Operating Instructions
This section details how to operate your Scheppach MS197-51-3W lawn mower safely and effectively.
4.1 Starting the Engine
- Ensure the fuel tank is filled and the oil level is correct.
- Press the primer bulb (if equipped) several times until fuel is visible.
- Move the throttle lever to the 'START' or 'CHOKE' position.
- Pull the starter cord firmly and smoothly until the engine starts.
- Once the engine runs, move the throttle lever to the 'RUN' position.
4.2 Adjusting Cutting Height
The cutting height can be adjusted to 7 levels, from 25 mm to 75 mm. Locate the height adjustment lever(s) on the mower deck and move them to the desired position. Always adjust the cutting height when the engine is off and the blades are stationary.
4.3 Mowing Techniques
The MS197-51-3W offers multiple mowing functions:
- Mowing with Collection: Attach the grass collection box to gather clippings. Empty the box when full to maintain optimal performance.
- Mulching: For mulching, remove the grass collection box and insert the mulching plug (if included). This finely chops grass clippings and returns them to the lawn as natural fertilizer.
- Side Discharge: For side discharge, remove the grass collection box and mulching plug, then attach the side discharge chute. This disperses clippings to the side.

4.4 Engaging the Drive Wheel
The mower is equipped with a drive wheel for easier operation. To engage the drive, squeeze the drive lever on the handle. Release the lever to disengage the drive.
4.5 Stopping the Engine
To stop the engine, release the engine brake lever (usually located on the handle). The engine will shut off automatically. Wait for all moving parts to stop before approaching the mower.
5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your lawn mower. Always disconnect the spark plug wire before performing any maintenance.
5.1 Cleaning
After each use, clean the underside of the mower deck to prevent grass buildup, which can affect cutting performance. The mower features an 'Easy Clean' function: connect a garden hose to the designated port, start the engine, and let the rotating blade clean the deck. Ensure the engine is off and cool before manually cleaning any remaining debris.

5.2 Blade Care
Regularly inspect the cutting blade for sharpness and damage. A dull blade tears grass, leading to an unhealthy lawn. Sharpen or replace the blade as needed. Always wear heavy-duty gloves when handling the blade.
5.3 Engine Maintenance
- Oil Change: Change the engine oil after the first 5 hours of operation, then every 25-50 hours or annually, whichever comes first.
- Air Filter: Clean or replace the air filter regularly, especially in dusty conditions, to ensure proper engine performance.
- Spark Plug: Inspect and clean the spark plug annually. Replace if worn or fouled.
5.4 Storage
For long-term storage, especially over winter:
- Drain the fuel tank or add a fuel stabilizer.
- Change the engine oil.
- Clean the mower thoroughly.
- Store in a dry, well-ventilated area. The foldable handle allows for space-saving storage.
