  • การทำความสะอาด: After each use, disconnect the mower from power and carefully clean any grass clippings or debris from the blade and underside of the mower deck. This prevents buildup and corrosion.

  • Poor Cutting Performance (Uneven Cut, Torn Grass):
    • Confirm the blade is installed with the cutting edges facing the correct direction.
    • ตรวจสอบใบมีดว่าทื่อหรือชำรุดหรือไม่
    • Ensure the mower deck height is set appropriately for the grass type and conditions.
  • ใบพัดไม่หมุน:
    • Ensure the mower is plugged in and receiving power.
