Maintaining Snowthrower

described in this manual. Shut engine off before
performing any maintenance service or
adjustment. Additionally, pull wire off spark
plug and keep wire away from plug to prevent
accidental starting. If major repairs are ever
needed, contact your local Authorized TORO
Service Dealer for assistance.
25. Keep snowthrower in safe operating condition
by keeping nuts, bolts, and screws tight. Check
engine mounting bolts frequently to assure they
are tight.

governor settings. Recommended maximum
engine speed is 3500 rpm. To assure safety and
accuracy, check maximum engine speed (3500
rpm) with a tachometer.

enclosure such as a garage or storage shed.
