How to use

Before use, check fuel level and engine oil according to the engine manufacturer’s guidance. Adjust the cutting height to the desired setting and ensure the grass bag (if fitted) or rear discharge is correctly attached. Start the engine following the standard pull-start procedure for small petrol engines, then walk behind the mower at a steady pace, overlapping each pass slightly for an even cut. Empty the grass collector regularly and clean any accumulated clippings from the cutting deck after use. Perform routine maintenance such as spark plug inspection, air filter cleaning, and blade sharpening according to the user manual schedule.

Usage recommendations

Use fresh unleaded petrol and a compatible engine oil grade. Mow when grass is dry for best results, and avoid cutting more than one-third of the grass blade length in a single pass to maintain lawn health. Store the mower in a dry, ventilated area and follow the engine manufacturer’s maintenance intervals to prolong service life.
