If you did not order the optional remote high idle, ensure that the dummy
plug (supplied) is installed on the end of the high idle cable! If you did
not receive a dummy plug, or have lost it, you NEED one!

PRO
and
RTU
series governors have an additional cable
port labeled high idle which can be used to provide a high idle switch at a remote
location on the vehicle. The PRO-38H High Idle Kit provides all the necessary compo-
nents needed to hook up this optional switch, including locking potentiometer, dpdt
switch, 12V lamp indicator and 12 foot cable.
How do I activate the high idle ?
To activate the high idle, simply toggle the high idle switch to ON. The high idle
activated indicator light will go on and the engine will rise to the preset speed (set by the
locking potentiometer).
How do I change the high idle speed ?
Loosen the lock nut on the potentiometer. Use a small screw driver to rotate the potenti-
ometer to raise the RPM. Using the tachometer in the cab as a reference, monitor the
speed of the engine until you reach the desired speed. Once the desired RPM is reached,
tighten the lock nut to lock in the new high idle speed.
WARNING : Turn off high idle before shutting the engine off !
* Note: The Hi-Idle function is not available for:
