Operating Instructions
Belt
Be sure to relieve all system
pressure then lock out power and
tag compressor to prevent
unexpected movement of the unit.
Inspect belt tension after first 30 hours of operation
then at every 1,000 hours.
1. Check belt tensioner to make sure spring
cups totally enclose spring. When cups are
touching, the belt is adjusted properly.
2. Always replace all belts with the same brand,
at the same time. Make sure belts are uni-
matched. Do not replace belts independently.
3. Do not splash lubricating oil on belts or pul-
leys when adjusting or replacing belts.
System Pressure
System pressure is factory set but can be regulated
depending on operating conditions. Refer to com-
puter control specifications for setting adjustments
or PLC operating manual.
Safety Valve
NEVER attempt to regulate or
tamper with safety valve. Valve is
sealed and certified by ASME code
and is designed to relieve system
pressure when necessary.
Check proper operation of safety valve before each
use. Refer to figure 11. If valve does not open man-
ually, replace immediately. Discharge pressure is
generally set at 175 PSI (12.1 bar). DO NOT attempt
to open valve while machine is under pressure.
Air/Oil Separator Filter
Air/Oil Separator tank is a
pressurized component. To avoid
serious injury, be sure system
pressure is relieved before
removing filter. Be aware oil
temperature may be very hot. Use
caution when changing filter.
1. Relieve all air pressure from air/oil separator
tank, then wait approximately 5-10 minutes
before replacing filter.
2. Replace air/oil separator filter. Do not at-
tempt to clean.
