STORAGE RECOMMENDATIONS

Lower the snow thrower to the ground.

Remove the snow thrower from the tractor.

Clean the snow thrower thoroughly. Wash off any salt deposit which may have dried on the thrower and housing.

Any bare metal that has become exposed should be painted or coated with a light oil to prevent rust.

Store in a dry place.
