Lubricating the Snowthrower

Lightly lubricate all moving parts of the snowthrower after
every 15 operating hours and at the end of the
snowthrowing season.

or friction drive plate because the wheel will slip and the
rubber may deteriorate.
1. Stop the engine and wait for all moving parts to stop.
2. Disconnect the wire from the spark plug and ensure that
the wire does not contact the plug (Fig. 18).
3. Drain the gasoline from the fuel tank; refer to Emptying
the Fuel Tank on page 24.
