Stationary Mode
To operate the PTO in this mode the vehicle must meet
the following conditions:
• Be in PARK position (vehicles equipped with auto-
matic transmission)
• Upfitter provider (on/off) switch has been activated
• Parking brake applied (vehicles equipped with
manual transmission)
• Brake pedal must not be applied
• Vehicle engine must be running
• No vehicle, brake or clutch switch faults present
• PTO must be correctly installed using the vehicle
provided circuits
The customer has the choice to operate the PTO by
utilizing the cruise control switches or by utilizing a
remote control (provided by the PTO supplier). To oper-
ate the feature using the cruise control switches, the
customer must first activate the upfitter-provided on/off
switch which will turn on the PTO. In order to increase or
decrease the engine idle speed, to optimize the PTO
function, the “RESUME/ACCEL” and “DECEL” cruise
switches can be used respectively. To disengage PTO
operation and return to “standard vehicle operation”
simply turn the upfitter-provided on/off switch to the
OFF position.
The torque converter lockup clutch will automatically
engage at engine speeds above 1,200 RPM (engine speed)
in PTO stationary mode. Once engaged, the lockup clutch
will remain on and not disengage until the engine speed
is below 1,000 RPM. Lockup clutch engagement is desir-
able for certain types of PTO applications (AS68RC
Six-Speed Automatic Transmission Only).
