6) When receiver pressure gauge reads
Air does not
at least 100 psi, check receiver safety
valve by puling safety link If air does
not escape from receiver valve repeat
above procedures to install another
new safety valve.
7) Remove redtag from power panel 1
circuit breaker 3P5.
Check that air pressure gauges on air
pressure regulators 1 and 2 Indicate 40
psi. If not, set pressure regulators 1 and
2 by turning adjusting screw on bottom
of regulator clockwise to decrease and
counterclockwise to increase air pres-
sure beyond regulator.
k. Check for normal operation -when set
Air pressure does
on AUTO, compressor cycles on and off
not maintain nor-
to maintain proper air pressure. If not
normal, shut down using extendedshut-
down procedures and troubleshoot
Make repairs/adjustments as required.
DO NOT use compressed air to clean cloth-
ing or work space. High pressure (HP) air
turns small particles Into dangerous projec-
tiles that may cause bodily Injury.
When using compressed air to clean equip-
merit, ALWAYS use protective shield to pro-
tect eyes and face from flying particles.
