Quincy Compressor 390

Measure the span length of the drive (in inches)

Calculate the required deflection (in inches)

Lay a straightedge across the top outer surface of the drive belt from pulley to sheave

Apply pressure with a belt tension gauge and record the deflection force reading

Is the deflection force reading within the minimum and maximum values?

Adjust the belt(s) if necessary

For new belts, tension to the maximum value plus 33%

Disconnect & lockout the compressor from the power source (electric models) or disconnect the spark plug wire from the spark plug (gas engine models).

Is the compressor stored in a heated area if subjected to freezing temperatures?

Enter the current air pressure in the tank (PSIG).

Is the air pressure in the tank 30 PSIG or less?

Open the drain valve and allow the moisture and air mixture to drain from the tank.

Close the drain valve once the moisture has been completely drained.

Record oil level on bayonet gauge

Drain drop legs and traps in air distribution system

Perform overall visual inspection of the compressor

Ensure safety guards are in place

Is there any unusual noise or vibration?

Change oil if 1000 hours or 6 months have passed, whichever occurs first

Was the oil changed more frequently due to harsher conditions?

Inspect compressor valves for leakage

Inspect compressor valves for carbon build-up

Crankcase and Sump Strainer Cleaning

Clean oil sump strainer screen inside the crankcase with safety solvent

Check lubricant level in the crankcase

Has the compressor operated for 100 hours or 1 month?

Replace break-in lubricant with QuinCip lubricant

Determine correct amount and viscosity of lubricant

Is the lubricant's pour point at least 15°F lower than the minimum expected ambient temperature?
