Cold Start Lamp
„ If the hydraulic oil temperature is below 125°F, or if
the engine coolant temperature is below 160°F, the
engine will rise to 1,750 rpm to warm the system.
„ If the hydraulic oil temperature is below 125°F, oil
will be forced over the pitch relief valve to raise the
oil temperature.
„ The cold start lamp indicator (AMBER) will remain
on until the hydraulic oil reaches 130°F as shown in
Figure 22 in the hydraulic system or at a 30-minute
default time. The hydraulic cooling fan will come
back on and the hydraulic fluid will be diverted
away from the pitch relief valve.
NOTICE
The cold start lamp indicator is located in two locations
on the right control console. An indicator is above the
diagnostic system display, and the other is between the
ignition key and light control rocker switch.
