Inadequate delivery pressure or defective components
operations can generally be traced to leakage, blocked
lines, or the buildup of moisture and sediment in the
system. A regular program of preventive maintenance
is an essential part of air system operation. The mate-
rials presented here are listed in accordance with the
MAINTENACE CHECK LIST in this section. Consider-
ation of severe working conditions may dictate a revi-
sion in schedule periodic checks.
DAILY:
AIR TANKS Open the air tank drain cocks at least
once daily to blow out moisture and accumulated sed-
iment. The drain cocks are located on the frame rail by
the battery box.
WEEKLY:
AIR SYSTEM SAFTY VALVE Manually actuate the air
system safety relief valve by pushing in on the stem.
