OPERATION
ENGINE THROTTLE
The engine throttle has three primary speed settings: Idle,
Charge, and Operating RPM.
1. Each press of the Throttle Switch (Figure 13) steps it
from idle to operating speed if operator presence is
detected.
Figure 13. Throttle Switch
2. The speed defaults to idle at startup or when no
operator presence is detected.
3. The speed defaults to full speed when the foot pedal is
depressed and operator presence is detected.
Battery Management
Idle speed is raised automatically to prevent battery drain
when:
Hydraulic oil cooler fan is running.
Lights are on
Battery voltage drops below preset voltage
Cold Start
1. Idle speed is raised automatically to expedite bringing
machine to operating temperature when:
Hydraulic oil is below preset temperature (Oil
forces across relief valve to raise oil temperature).
Engine coolant temperature is below preset
temperature.
2. Aux 1 on indicator will light when machine is in cold
start mode.
Safety Interlocks
1. Full engine throttle is allowed only when operator
presence detected.

2. Engine speed changes to idle when operator leaves
the seat or the foot pedal is released for more than a
set period of time.
PUMP STROKE
Stroke is proportionally controlled by the foot pedal input
position via feedback from the stroke position sensor.
Safety Interlock
1. Pump is automatically de-stroked if operator presence
not detected.
2. Upon startup, the foot pedal will not control pump
stroke if the pedal is depressed unless it has been
released after start up. This prevents machine from
unintentionally moving when started.
3. Pump is automatically de-stroked if error is detected
from foot pedal sensor.
4. Stroke position is directly controlled by foot pedal if
error is detected from the stroke sensor.
CRUISE CONTROL
Setting the Cruise Control will set and maintain a set pump
stroke position command.
1. Press the cruise control switch (Figure 14) to engage
the cruise control. The cruise control switch LED
indicator lights when cruise control is engaged.
