Maintenance
Important: All electrical repairs should be performed only by an
Authorized Service Dealer.
Note:
Determine the left and right sides of the machine from the
normal operating position.
If the extension cord is plugged into the snowthrower,
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.
Lubricating the Snowthrower
You do not need to lubricate the snowthrower; all the bearings were
lubricated at the factory for the life of the snowthrower.
Replacing the Scraper
The scraper is located at the bottom of the rotor housing as shown
in Figure 11.

You may need to tap the Allen wrench with a hammer to
loosen the rotor shaft. Wedge a stick or a hammer handle in the
rotor to prevent it from rotating.
Note:
If you cannot remove the rotor shaft by holding the rotor,
remove the left side cover and the skid (Figure 14).
