Notes:
75. Check sight glass after compressor has run for 10 minutes. Oil should be at the half-way point in the sight glass.
Add compressor oil as required to maintain proper level. Remove excess oil if above half-way point in sight glass.
Loosen drain plug only enough for oil to seep from around the plug. Do not totally remove plug or too much oil may be
lost.
CAUTION
Insure that the suction and discharge service valves are front seated prior to loosening
drain plug. Bleed compressor crankcase prior to placing system back on line.
