3. Adding Fuel and Oil:

• Engine Oil: Before starting for the first time, fill the engine with the recommended type and amount of engine oil (refer to the engine manual for specifics). Do not overfill.
• Fuel: Fill the fuel tank with fresh, unleaded gasoline. Do not use E85 or other high-ethanol fuels. Ensure the fuel cap is securely tightened.
• Always perform these steps outdoors and away from ignition sources.

Operating Instructions

1. Starting the Engine:

• Ensure the spark plug wire is securely connected.
• Push the primer bulb (if equipped) 3-5 times until fuel is visible.
• Move the throttle lever to the 'START' or 'CHOKE' position.
• Firmly pull the starter rope until the engine starts. Once started, move the throttle to the 'RUN' position.

2. Adjusting Cutting Height:

• The MGF G51SHL features centralized height adjustment. With the engine off, locate the height adjustment lever near one of the wheels.
• Pull the lever outwards and move it to the desired cutting height setting. Ensure all wheels are set to the same height.

3. Mowing Techniques (4-in-1 System):

• Grass Collection: Attach the grass collection bag to the rear discharge opening. This collects clippings for disposal.
• Side Discharge: Remove the grass bag and mulching plug (if installed). Attach the side discharge chute to direct clippings away from the mower.
• Mulching: Remove the grass bag and side discharge chute. Insert the mulching plug into the rear discharge opening. This finely chops clippings and returns them to the lawn as fertilizer.
• Rear Discharge: With no bag, chute, or plug, clippings are discharged from the rear.

4. Engaging Self-Propel:

• Once the engine is running, engage the self-propel lever on the handlebar. The mower will begin to move forward.
• Release the lever to disengage the self-propel function.

5. Stopping the Engine:

• Release the engine brake lever (usually located on the handlebar). The engine will stop automatically.
• For emergency stops, simply release the engine brake lever.

Maintenance

Regular maintenance ensures optimal performance and extends the life of your MGF G51SHL lawn mower.

1. Cleaning the Mower:

• After each use, clean the underside of the deck to prevent grass buildup.
• The mower is equipped with a washing connector. Attach a garden hose to this connector, start the engine, and engage the blade for a few minutes to clean the deck.
• Always disconnect the spark plug wire before cleaning or performing any maintenance.

2. Blade Maintenance:

• Regularly inspect the multi-purpose blade for sharpness and damage. A dull blade tears grass, leading to an unhealthy lawn.
• If the blade is dull, have it sharpened by a qualified service technician or replace it with a genuine MGF replacement blade.
• Always disconnect the spark plug wire and wear heavy-duty gloves when handling the blade.

• 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: Inspect and clean the air filter regularly. Replace if heavily soiled or damaged.
• Spark Plug: Inspect and clean the spark plug annually. Replace if worn or fouled.
• Refer to the separate engine manual for detailed engine maintenance schedules and procedures.

4. Storage:

• Before storing for extended periods, drain the fuel tank or add a fuel stabilizer.
• Clean the mower thoroughly.
• Store in a dry, well-ventilated area, away from direct sunlight and extreme temperatures.
