4. Operation

4.1 Starting the Lawn Mower

  1. Ensure batteries are installed and the safety key is inserted.
  2. Press and hold the safety button (if applicable), then pull the bail lever towards the handlebar. The motor will start.
  3. Release the safety button once the motor is running.

4.2 Adjusting Cutting Height

The mower offers 6 cutting height settings from 25mm to 75mm.

  1. Turn off the lawn mower and remove the safety key.
  2. Locate the cutting height adjustment lever, usually on the side of the mower deck.
  3. Pull the lever outwards and move it to the desired height setting. Ensure it locks securely into position.
  4. For best results, avoid cutting more than one-third of the grass blade length at a time.

4.3 Mowing Tips

  • Mow in overlapping rows for an even cut.
  • For thick or tall grass, consider raising the cutting height for the first pass and then lowering it for a second pass.
  • The side grass comb helps cut grass close to walls and fences.
  • Empty the grass collector regularly to maintain optimal performance and prevent clogging.

5. Maintenance

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

Always remove the safety key and batteries before performing any maintenance.

5.1 Cleaning

  • After each use, clean the underside of the cutting deck to remove grass clippings and debris. Use a brush or scraper.
  • Wipe down the exterior of the mower with a damp cloth. Do not use water jets or high-pressure cleaners.
  • Ensure the grass collector is clean and free of blockages.

5.2 Blade Care

  • Periodically inspect the cutting 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 service technician. If damaged, replace it with an original Litheli replacement blade.
  • When handling the blade, always wear heavy-duty gloves.

5.3 Storage

  • Before storing, ensure the mower is clean and dry.
  • Remove the batteries from the mower and store them in a cool, dry place, away from direct sunlight and extreme temperatures.
