STORAGE

WARNING: AVOID INJURY. Read

and understand the entire Safety section before proceeding.

SHORT TERM

IMPORTANT: NEVER spray unit with high

pressure water or store unit outdoors. Run with attachment clutch engaged a few

minutes after each use to free unit of any loose or melting snow.

Close fuel shut-off valve. Inspect unit for visible signs of wear,

breakage or damage. Keep all nuts, bolts and screws properly

tightened and know unit is in safe working condition.

Store unit in a cool, dry protected area.

LONG TERM

Clean unit thoroughly with mild soap and low pressure water and lubricate (see MAINTENANCE on page 22). Touch up all scratched painted surfaces.

Remove weight from wheels by putting blocks under frame or axle.

Fuel System

Gasoline left in the fuel system for extended periods without a stabilizer will deteriorate, resulting in gum deposits in the system. These deposits can damage the carburetor and the fuel hoses, filter and tank. Prevent deposits from forming in the fuel system during storage by adding a quality fuel stabilizer to the fuel. Follow the recommended mix ratio found on the fuel stabilizer container.

To treat the fuel system for storage:

1. Add fuel stabilizer (Ariens p/n 00592900) according to manufacturers’ instructions.

2. Run engine for at least 10 minutes after adding stabilizer to allow it to reach the carburetor.

NEVER store the engine with fuel in the fuel tank inside of a building with potential sources of ignition.
