4.2 HYDRAULIC SYSTEM WARM UP
The control system monitors the hydraulic system in extremely
cold temperatures and provides optimal performance by auto-
matically limiting the function speeds of the high demand func-
tions. The warm up mode automatically shuts off when system oil
reaches allowable temperatures.
While the system is cold and in the warm up mode, the tower lift,
main lift, and main telescope functions are limited to creep
speeds and is indicated to the operator by flashing the creep light
on the platform control panel.
Functions being operated when the warm up mode turns off will
remain in the creep speed until the function is re-initiated.
