6. Operating Instructions

6.1 Starting the Mower

To start the Litheli Cordless Lawn Mower:

1. Insert the fully charged battery into the battery compartment.
2. Press and hold the safety button located on the handle.
3. While holding the safety button, pull the bail switch lever towards the handle. The motor will start.

6.2 Mowing Tips

• For best results, mow dry grass. Wet grass can clog the mower and lead to an uneven cut.
• Overlap cutting paths slightly to ensure complete coverage.
• Avoid cutting more than one-third of the grass blade length at a time. If the grass is very tall, make multiple passes, gradually lowering the cutting height.
• The 13-inch cutting width is ideal for small to medium-sized lawns, covering up to 1,300 sq. ft. on a single charge.
• The high-performance motor provides 3400 RPM for efficient cutting.

7. Maintenance

Regular maintenance ensures the longevity and optimal performance of your lawn mower.

7.1 Cleaning

• Always remove the battery before cleaning.
• Use a brush or cloth to remove grass clippings from the mower deck, wheels, and grass bag.
• Do not use water directly on the motor or electrical components.
• Empty the 8-gallon grass bag regularly to maintain collection efficiency.

7.2 Blade Care

• The mower features a durable manganese steel blade.
• Periodically inspect the blade for sharpness and damage. A dull or damaged blade can lead to poor cutting performance and strain the motor.
• If the blade is dull, it can be sharpened by a qualified professional. If it is bent or cracked, it must be replaced.
• Always wear heavy-duty gloves when handling the blade.
