WARN I N G
Cold ambient temperatures could result in loss of secondary braking capability due to
inadequate hydraulic accumulator nitrogen pre-charge. Loss of the secondary braking
system as well as main hydraulic pressure will result in little or no braking capability and a
potential for injury or death.
Perform a brake accumulator check anytime machine has been idle for longer than two
hours below -13F (-25C). Failure to follow these warnings may result in injury or death to
personnel.
N OT E
Alert indicator will illuminate when brake accumulator pressure is below operational
standard.
1. Move engine start switch to ON position. Alert indicator (Figure 1, Item 1) will come on if accumulator pressure
is below operational standard.
