2. Safety Instructions

Always follow these safety guidelines to prevent injury and damage to the equipment.

• Read the Manual: Familiarize yourself with all controls and proper use before operating the mower.
• Personal Protective Equipment: Always wear sturdy footwear, long trousers, and eye protection. Avoid loose clothing that could get caught in moving parts.
• Clear the Area: Before mowing, remove all objects such as stones, sticks, wires, bones, and other debris from the lawn that could be thrown by the blade.
• Keep Bystanders Away: Ensure children, pets, and other people are at a safe distance (at least 15 meters) from the mowing area.

2. Grass Collector Assembly: Assemble the grass bag according to the instructions and attach it to the rear of the mower.
3. Check Connections: Verify that all connections, especially the spark plug wire and safety levers, are securely in place.

4.2. Fuel and Oil

The engine is shipped without oil or fuel. It is critical to add both before starting the mower.

1. Add Engine Oil: Remove the oil fill cap/dipstick. Slowly pour the recommended 4-stroke engine oil (e.g., SAE 30 or 10W-30) into the oil fill opening until it reaches the 'FULL' mark on the dipstick. Do not overfill.
2. Add Fuel: Fill the fuel tank with fresh, unleaded gasoline. Do not use E85 or E15 fuel. Leave some space for fuel expansion. Securely replace the fuel cap.

4.3. Battery Charging (for Electric Start)

If your model includes an electric start, ensure the battery is charged before first use. Refer to the separate battery charger instructions for details. Connect the charger to the battery and a power outlet until fully charged.

5. Operating Instructions

2. Choke: Move the choke lever to the 'CHOKE' position (for cold starts).
3. Safety Lever: Hold the engine safety lever (bail bar) against the handlebar.
4. Electric Start: Press and hold the electric start button until the engine starts. Release the button once the engine is running.
5. Manual Start: If electric start is not available or battery is low, pull the recoil starter handle firmly and smoothly until the engine starts.
6. Warm-up: Once the engine starts, gradually move the choke lever to the 'RUN' position as the engine warms up.

5.2. Stopping the Engine

Release the engine safety lever (bail bar). The engine will automatically shut off.

5.3. Adjusting Cutting Height

The GREENCUT GLM770XE offers 7 cutting height positions, ranging from 25mm to 75mm.

1. Ensure the engine is OFF and the spark plug wire is disconnected.
2. Locate the height adjustment lever on each wheel or a central lever.

5.4. Mowing Techniques

For best results, mow when the grass is dry. Overlap cutting swaths slightly. For very tall grass, it is recommended to make two passes, setting the cutting height higher for the first pass and then lowering it for the second.
