The PTO switch controls the power take off. The

sound and appear if the engine speed is greater
than 950 RPM when the PTO is engaged.
To start the PTO, press the PTO switch . The
touch panel will display the HOPPER MODE
screen and the light above the switch will come
on. The PTO will start and the idle speech will
increase
FAST IDLE
When the PTO or
sweep switch is pressed while
the transmission is in neutral and the service
brake is depressed, the engine RPM will raise to
the fast idle setting of 1100 RPM.
The fast idle setting is useful for lifting the hopper
or starting the sweeping operations. The fast idle
is cancelled by pressing the service brake.

sound and appear if the engine speed becomes
greater than 2200 RPM while the PTO is

off, and press the PTO switch again. The light
above the PTO switch will turn off.
