5 preset idle speeds (sub set of remote PTO)
This feature comes factory preset to the following 5 engine idle speeds 900, 1100, 1300,
1500, 1700 rpm’s. They are attained by successively toggling the PTO switch on and off,
by doing so the idle speeds will step through the preset speeds and will wrap back around
to the beginning set speed if the on/off switch is toggled enough times. These set speeds
can be changed to any speed between 900 and 2000 rpm’s using a dealer service tool.
This will give the customer the ability to have multiple idle speeds to operate his/her
equipment.

is not to be used for main vehicle accelerator.
