- Before performing any maintenance or adjustments, always turn off the engine and disconnect the spark plug wire to prevent accidental starting.

2. Engine Preparation
Your MTD ThorX engine requires oil and fuel before its first use. Refer to the engine manual for specific oil type and capacity. Fill the fuel tank with fresh, unleaded gasoline (E10 compatible) as specified by the engine manufacturer. Do not overfill.
3. Brush Height Adjustment
The sweeper features a stable swivel wheel and a unique brush lift function for reversing. Adjust the brush height to suit the surface and type of debris. For general sweeping, the brush should lightly contact the surface. For snow removal, a slightly higher setting might be appropriate to prevent excessive drag.
4. Attaching Optional Accessories
The Optima PS 700 is compatible with optional accessories such as a collection container (Part No.: 196-067-000, 47-liter volume) or a snow blade. Attach these accessories securely following their respective instruction manuals.

Operating Instructions
Follow these steps for safe and effective operation of your sweeper.
1. Starting the Engine
- Ensure the fuel tank is filled and the oil level is correct.
- Move the choke lever to the 'CHOKE' position (for cold starts).
- Press the primer bulb 3-5 times until fuel is visible in the bulb.
- Pull the starter rope firmly until the engine starts.
- Once the engine runs smoothly, gradually move the choke lever to the 'RUN' position.
2. Engaging the Brush
Once the engine is running, engage the brush lever to start the sweeping action. The brush will begin to rotate, clearing debris from the path.
3. Sweeping Operation
Guide the sweeper forward at a comfortable pace. The stable swivel wheel allows for easy maneuvering. For optimal cleaning, overlap each pass slightly. The machine is versatile and can be used for various tasks, including clearing leaves, dirt, gravel, and even light snow.

When backing up, utilize the unique brush lift function to raise the brush off the ground. This prevents unnecessary wear on the brush and makes maneuvering easier.
5. Shutting Down
To stop the engine, move the throttle lever to the 'STOP' position or turn the ignition key (if equipped) to 'OFF'. Allow the engine to cool before storage.
