- Move the throttle lever to the 'Start' or 'Choke' position.
- Firmly pull the starter cable until the engine starts.
- Once the engine starts, move the throttle lever to the 'Run' position.
4.2 Adjusting Cutting Height
The lawnmower features 7 levels of cutting height adjustment, from 0.7 inches to 3.2 inches.

To adjust the cutting height, locate the height adjusting lever near the wheels. Move the lever to the desired position. For best results, avoid cutting more than one-third of the grass blade length at a time.
4.3 3-in-1 Functions: Bagging, Mulching, and Side Discharge
This lawnmower offers versatile grass clipping management options.

- Bagging: Attach the grass catcher box to collect clippings for a clean lawn finish. The large 62L catcher reduces emptying frequency.
- Mulching: Remove the grass catcher and close the side discharge chute. The blade will cut grass into fine pieces, returning nutrients to the lawn.
- Side Discharge: Attach the side discharge chute to direct clippings out the side of the mower, useful for taller grass or when bagging is not desired.
4.4 Mowing Tips
- Mow when the grass is dry for optimal results.
- Overlap cutting paths slightly to ensure an even cut.
- When mowing on slopes, maintain a firm grip and stable footing. The mower is designed for stable operation on sloped yards.
5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your lawnmower.
5.1 Engine Maintenance

- 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, especially in dusty conditions. Replace if damaged.
- Spark Plug: Inspect the spark plug annually. Clean or replace as needed to ensure easy starting and efficient engine operation.
5.2 Blade Maintenance
- Blade Inspection: Regularly check the cutting blade for sharpness and damage. A dull blade can tear grass, leading to an unhealthy lawn.
- Blade Sharpening/Replacement: Have the blade sharpened or replaced by a qualified service technician if it is dull or damaged.
5.3 General Cleaning and Storage
- Chassis Cleaning: After each use, clean the underside of the cutting deck to prevent grass buildup. The thickened metal chassis is designed for durability and resistance to corrosion.
- Storage: Store the lawnmower in a clean, dry area. If storing for an extended period, drain the fuel or use a fuel stabilizer.
