Air System Maintenance
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
materials presented here are listed in accordance with the
Machine Maintenance Checklist
on page 134. Consideration of severe working conditions may dictate a revision in
schedule periodic checks.
DAILY:
AIR TANKS
Open the air tank drain cocks at least once daily to blow out moisture and accumulated
sediment. The drain cocks are located on the frame rail by the battery box.
WEEKLY:
AIR SYSTEM SAFETY VALVE
Manually actuate the air system safety relief valve (1) by pushing in on the stem. This will
ensure that the valve is not sticking. If the valve cannot be actuated in this manner, it
should be repaired or replaced.
