Quincy Compressor X8

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, was the tension initially set to the maximum value plus 33%?

Ensure the following are in place before starting the compressor

Replace the break-in lubricant after 100 hours of operation or 1 month

Verify the following lubricant characteristics

Enter the approximate crankcase oil capacity for your model

Enter the viscosity of the lubricant to use

Ensure the compressor is disconnected from the power supply

Verify that all safety precautions from SECTION 5, Stopping For Maintenance, are followed

Remove the pressure switch cover

Record the current air pressure reading

Adjust the spring loaded adjustment screw

Enter the new air pressure reading after adjustment

Measure Span Length and Deflection

Measure the span length of the drive

Calculate the required deflection in inches

Measure and Adjust Belt Tension

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 the deflection force is not within the specified range

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

Manually operate the pressure relief valves to ensure they are working

Clean the cooling surfaces of the intercooler

Clean the cooling surfaces of the compressor

Check the compressor for air leaks

Check the compressed air distribution system for leaks
