5. Mowing Tips
- For best results, mow when the grass is dry.
- Do not cut more than one-third of the grass blade length at a time.
- Overlap mowing strips slightly to ensure an even cut.
- Change mowing patterns regularly to prevent matting and uneven growth.
Maintenance
Regular maintenance ensures optimal performance and extends the life of your lawn mower. Always disconnect the battery before performing any maintenance.
1. Cleaning
- After each use, clean the underside of the mower deck to remove grass clippings and debris.
- Wipe down the exterior with a damp cloth. Do not use water jets or high-pressure washers directly on the mower.
- Ensure the grass bag is emptied and cleaned regularly.
2. Blade Care
- Inspect the blade regularly for sharpness and damage. A dull blade can tear grass, leading to an unhealthy lawn.
- If the blade is dull or damaged, have it sharpened or replaced by a qualified service technician.
- Always wear heavy-duty gloves when handling the blade.
3. Battery Care
- Store batteries in a cool, dry place, away from direct sunlight and extreme temperatures.
