Maintenance
Note: Determine the left and right sides of the
snowthrower by standing in the normal operating position.
If the extension cord is plugged into the
snowthrower and the key is in the handle,
someone could accidentally operate snowthrower
while you are performing maintenance on it,
causing serious personal injury.
Disconnect the extension cord before you perform
any maintenance. Hold the key down, turn it
clockwise and remove it from the handle.
Warning

You do not need to lubricate the snowthrower; all the
bearings were lubricated at the factory for the life of the
snowthrower.
