4. Setup
Follow these steps to prepare your lawnmower for first use:

- Grass Collector Assembly: Assemble the grass collector bag according to the instructions provided with the bag. Attach it to the rear of the lawnmower.
- Add Engine Oil: Fill the engine with the recommended 4-stroke engine oil. Refer to the engine oil capacity in the specifications. Use FUXTEC original oils for optimal performance. Do not overfill.
- Add Fuel: Fill the fuel tank with unleaded petrol. Do not use E85 or other alternative fuels. Ensure the fuel cap is securely tightened.
- Initial Checks: Before starting, check that all fasteners are tight, the blade is securely attached, and the cutting height is set as desired.


5. Operating
Understand the various functions and controls for effective lawn mowing.
5.1 Starting the Engine
- Ensure the spark plug wire is connected.
- Push the primer bulb (if equipped) 3-5 times.
- Move the throttle lever to the 'START' or 'CHOKE' position.
- Firmly pull the starter cord until the engine starts.
- Once started, move the throttle lever to the 'RUN' position.
5.2 Adjusting Cutting Height
The cutting height can be centrally adjusted to 7 levels, ranging from 25 mm to 75 mm. Locate the height adjustment lever on the side of the mower deck and move it to the desired position. Always adjust the height with the engine off.
5.3 Mowing Functions (4-in-1)
- Collecting: Attach the 60L grass collector bag to the rear discharge opening.
- Mulching: Insert the mulching plug into the rear discharge opening and remove the grass collector. The special mulching blade will cut grass into fine pieces, returning nutrients to the lawn.
- Side Discharge: Attach the side discharge chute to the side opening and remove the grass collector. This is ideal for taller grass where collection or mulching is not preferred.
- Rear Discharge: Operate without the grass collector or mulching plug, allowing clippings to be discharged from the rear.
5.4 Engaging Self-Propulsion
To engage the self-propulsion, squeeze the drive lever on the handle. Release the lever to disengage the drive. The rear-wheel drive system makes mowing easier, especially on larger areas or slight inclines.
5.5 Stopping the Engine
Release the engine brake lever (usually located on the handle) to stop the engine. For emergency stops, simply release this lever.


6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your lawnmower.
6.1 EasyClean System
The integrated EasyClean system allows for intuitive and easy cleaning of the mower deck after use or at the end of the mowing season. Connect a garden hose to the EasyClean port, start the engine, and let the rotating blade clean the underside of the deck. Always follow safety guidelines during this process.
6.2 Blade Care
Inspect the blade regularly for sharpness and damage. A dull or damaged blade can lead to poor cutting performance and excessive vibration. Sharpen or replace the blade as needed. Always disconnect the spark plug wire before inspecting or working on the blade.
6.3 Engine Maintenance
- Oil Change: Change the engine oil after the first 5 hours of operation, then every 25 hours or annually, whichever comes first.
- Air Filter: Clean or replace the air filter regularly, especially in dusty conditions, to ensure proper engine breathing.
- Spark Plug: Inspect and clean the spark plug annually. Replace if worn or fouled.
6.4 Storage
For long-term storage, especially over winter:
- Drain the fuel tank or add a fuel stabilizer.
- Change the engine oil.
- Clean the entire mower thoroughly, including the underside of the deck.
- Store in a dry, well-ventilated area, away from direct sunlight and extreme temperatures.
