Mowing: Before mowing, clear the area of obstacles. Always wear safety goggles and stout shoes. If grass or foreign objects block the mower, remove the lock key and battery cartridge, then wear gloves to clear the obstruction. This machine is for mowing lawns only and should not be used for weeds. Hold the handle firmly with both hands and walk at a speed of 2 to 4 seconds per meter. For long grass, mow in stages over several days. Empty the grass basket when it is full to prevent motor strain.
Adjusting Handle Height: Loosen thumb nuts, remove bolts, adjust to one of three levels, reinsert bolts, and tighten thumb nuts.
Using Mulching Plug: Remove the grass basket. Ensure grass length after cutting is 30 mm or more, and the cut length is 15 mm or less.
