- 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
