Important:

1500 m (5,000 ft) for a continuous period, ensure

that the High Altitude Kit has been installed

so that the engine meets CARB/EPA emission

regulations. The High Altitude Kit increases

engine performance while preventing spark-plug

fouling, hard starting, and increased emissions.

Once you have installed the kit, attach the

high-altitude label next to the serial decal on the

machine. Contact any Authorized Toro Service

Dealer to obtain the proper High Altitude Kit and

high-altitude label for your machine. To locate

a dealer convenient to you, access our website

at www.Toro.com or contact our Toro Customer

Care Department at the number(s) listed in your

Emission Control Warranty Statement. Remove

the kit from the engine and restore the engine to

its original factory configuration when running the

engine under 1500 m (5,000 ft). Do not operate an

engine that has been converted for high-altitude

use at lower altitudes; otherwise, you could

been converted for high-altitude use, look for the
