which attach it to the snow thrower housing.

Engine

Refer to the separate engine manual for all engine
maintenance procedures.

Check engine and snow thrower frequently for
loose hardware, and tighten as needed.

Lubrication

Lubricate pivot points on the control handle and the
extension spring at the end of the clutch cable with
a light oil once every season and before storage of
the snow thrower at the end of the season.

Lubricate the flange keepers on the chute crank
once a season with a light oil making sure the crank
rod moves freely. Remove bolts holding the shroud
to the housing, and lift shroud to access the chute
crank bracket.

WARNING:

Before servicing, repairing, or

inspecting, disengage all clutch levers and stop
engine. Wait until all moving parts have come
to a complete stop. Disconnect spark plug wire
and ground it against the engine to prevent
unintended starting.
