Air Tanks
When draining the air tanks, do not look into the
area of the draining air. Dirt or sludge particles
may be in the air stream and could cause eye
injury.
All air tanks on the vehicle should be drained daily. Empty any moisture
from air tanks by pulling the drain valve wire or by opening the drain
cocks and allowing the air pressure to drain completely. Make sure the
drain cocks close properly after draining. During draining the tanks
should be checked for condensation fluid even if an automatic drain
valve is installed.
Trucks with Wabco air dryers: Periodically drain the purge tank to check
for contamination, water, oil, etc.
