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

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.
