IMPORTANT: To assure product SAFETY and RELIABILITY, repairs, maintenance and adjustment should be performed by authorized service centers or other qualified service organizations. Use only identical replacement parts.

Inspect and thoroughly clean your mower at the beginning of each mowing season for longer life and better performance.
