Familiarize yourself with the main components of your GREENCUT GLM660X lawn mower.







4. Setup and Assembly
Your GREENCUT GLM660X comes partially assembled. Follow these steps for complete setup.
4.1. Handlebar Assembly
- Unfold the lower handle section and secure it with the provided knobs and bolts.
- Attach the upper handle section to the lower section, ensuring all cables are routed correctly and not pinched.
- Tighten all fasteners securely.
4.2. Grass Collection Bag Attachment
- Lift the rear discharge flap.
- Hook the grass collection bag onto the mower's frame under the flap. Ensure it is securely seated to prevent grass clippings from escaping.
4.3. Initial Fluid Checks
Before first use, ensure proper fluid levels.
- Engine Oil: The engine is shipped without oil. Fill the engine with appropriate 4-stroke engine oil (refer to engine manual for specific type and capacity). Do not overfill.
- Fuel: Fill the fuel tank with unleaded petrol. Do not use E85 or other alternative fuels. Ensure the fuel cap is securely tightened.
5. Operating Instructions
5.1. Starting the Engine
- Ensure the spark plug wire is securely connected.
- Move the mower to a level, clear area.
- Press the primer bulb (if equipped) 3-5 times until fuel is visible in the bulb.
- Move the throttle lever to the "START" or "CHOKE" position.
- Hold the engine brake lever against the handle. The engine will not start unless this lever is held.
- Pull the starter rope with a rapid, continuous motion until the engine starts.
- Once started, gradually move the throttle lever to the "RUN" position.
5.2. Adjusting Cutting Height
The GLM660X allows for 3 cutting height positions, ranging from 25mm to 75mm.

- Turn off the engine and wait for the blade to stop completely.
- Locate the height adjustment levers on each wheel (or a central lever if applicable).
- Move the levers to the desired height setting. Ensure all wheels are set to the same height for an even cut.
5.3. Mowing Techniques
- Mow across slopes, not up and down.
- Overlap cutting paths slightly to ensure complete coverage.
- Avoid cutting more than one-third of the grass blade length at a time.
- For best results, mow when the grass is dry.

5.4. Emptying the Collection Bag
The 35L collection bag should be emptied regularly to maintain optimal cutting performance and prevent clogging.
- Turn off the engine and wait for the blade to stop.
- Lift the rear discharge flap.
- Carefully remove the collection bag by unhooking it from the frame.
- Empty the clippings into a suitable receptacle.
- Reattach the bag securely before resuming operation.
6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your lawn mower. Always turn off the engine and disconnect the spark plug wire before performing any maintenance.
6.1. 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: Check the air filter regularly (every 10-25 hours, depending on conditions) and clean or replace if dirty. A dirty air filter can reduce engine performance.
- Spark Plug: Inspect the spark plug annually or every 50 hours. Clean or replace if fouled or worn.
6.2. Blade Maintenance
- Sharpening: A sharp blade ensures a clean cut. Sharpen the blade as needed, typically every 25 hours of operation. Ensure the blade is balanced after sharpening.
- Replacement: Replace the blade if it is bent, cracked, or excessively worn. Use only genuine GREENCUT replacement parts.
6.3. Cleaning and Storage
- Clean the underside of the mower deck after each use to prevent grass buildup, which can affect cutting performance.
- Clean the exterior of the mower with a damp cloth. Do not use a pressure washer directly on the engine or electrical components.
- For long-term storage, drain the fuel tank or add a fuel stabilizer. Store the mower in a dry, well-ventilated area.
