Preset PTO Mode

stand
‐
by engine speed (850 rpm)
when the PTO in-cab 1 switch
position is pressed or, by pressing
and releasing the remote arming
switch. Then within five seconds,
assert the remote PTO enable
switch to on. This provides an initial
start-up engine speed to match the
engagement of the PTO load.
The PTO standby engine speed
can be reprogrammed to a higher
speed by your dealer.
Choose one of two factory presets
by pressing the PTO In-cab
−
/SET or +/RES switch positions
or the remote PTO SET switch.
Speed 1 and Speed 2 are
programmable by a service
technician from base engine idle
rpm to max PTO operation speed
(3100 rpm).
.
Speed 1: Pressing the
−
/SET
position of the PTO switch
results in a preset speed of
1250 rpm.

Speed 2: Pressing the +/RES
position of the PTO switch
results in a preset speed of
1700 rpm.
Pressing the 0 switch position on
the PTO in-cab switch or moving the
remote PTO enable switch to OFF
results in the return of the engine
speed back to normal idle. The PTO
load relay is also disengaged.
Maximum PTO Operating Speed:
During PTO operation, the
accelerator pedal can be pressed to
adjust the engine speed. To protect
the PTO from over
‐
speed, the PTO
system will disengage when the
engine speed exceeds 2100 rpm.
The Stationary PTO Mode provides
both in

cab and remote controls.
The in
‐
cab controls are enabled as
the factory preset. The remote
controls are disabled. This factory
preset configuration can also be
reprogrammed to enable the remote
controls, and disable the in-cab
PTO controls (i.e., PTO switch,
accelerator pedal). See your dealer
for more information.
