Off-Season Storage

The following steps should be taken to prepare your lawn mower for storage.

•Clean and lubricate mower thoroughly as described in the lubrication instructions. Do not use a pressure washer or garden hose to clean your unit.

•Refer to engine manual for correct engine storage instructions.

•Coat mower’s cutting blade with chassis grease to prevent rusting.

•Store mower in a dry, clean area. Do not store next to corrosive materials, such as fertilizer.

When storing any type of power equipment in a poorly ventilated or metal storage shed, care should be taken to rust-proof the equipment. Using a light oil or silicone, coat the equipment, especially cables and all moving parts of your lawn mower before storage.
