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.
We do not recommend the use of 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.
