NOTES:

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 2,500 hours afterwards. Proper belt tension for 3 HP units is 7 lbs./.16” deflection; for 5 HP units, 7 lbs./.19” deflection.

4.See Compressor Pump Manuals for replacement or service procedures.
