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.
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). T ouch up all scratched painted surfaces.
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 manufacturer’s 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.
