1. Inspect and perform maintenance periodically according to maintenance schedule.
2. The maintenance schedule relates to the normal operating conditions. If the circumstances and load condition are adverse, shorten the cycle time and do
maintenance accordingly.
3. * The tension of the V-belt should be adjusted during the initial stage and inspected every 1,500 hours afterwards. Proper belt tension for 3/4 to 3 HP units is
12 lbs./.5” deflection; for 5 to 20 HP units, 16 lbs./1.5” deflection

facing the black fan shroud and
counterclockwise if facing the
compressor flywheel.)
c. Set both selector switches to the
auto position. Compressors will
both run until the lead pressure
switch closes.
d. Open valve at the air receiver
leading to Medical Air System.
e. Check for air leaks at the
connections.
9. Check that the compressor operates
without excessive vibration, unusual
noises or leaks.
10. Check the discharge pressure. Also
make sure the air pressure rises to the
designated pressure setting by
checking the discharge pressure
gauge.
11. Check the operation of the pressure
switch or the pilot valve for
continuous run units by opening
the stop valve and confirming the
compressor starts or reloads as
pressure drops.
