24.
3. Operate the machine for 15 minutes and then collect a lubricant sample for laboratory analysis.
The first lubricant change interval may need to be shortened to allow for complete removal of the cleaning
agent and contaminants.
The laboratory results will indicate the extent which cleaning agent and contaminants are still in the
system and determine when the pre-emptive lubricant change interval should occur.
Disassembly and mechanical cleaning will be required for removal of major semi-solid deposits or solid
deposits. It is therefore important that the lubricant system be properly maintained, and that lubricant
grades, types or brands not be mixed.
4.5.2
Long Term Storage
When starting a unit which has been idle for several months, it is recommended that the connection
above the inlet valve be removed and compressor lubricant be poured into the unit through the intake.
Add 1/2 cup of lubricant for every 10 HP of compressor size rating. Care must always be exercised when
working with inlet air and lubricant lines to keep foreign matter from entering the system. The air
compressor rotors run at close clearances and could be severely damaged by foreign material.
4.5.3
Changing Lubricants
When changing lubricant, always drain all components as thoroughly as possible to prevent
contamination of fresh lubricant. Drain when lubricant is hot to help prevent varnish deposits and to carry
away impurities. Completely drain lubricant system, including reservoir, air end, cooler(s) and piping.
4.5.4
Obtain Sample
Preferred sampling location is at the fluid filter during element change interval. If unable to use this point,
proceed as follows:
1. Shutdown and lockout compressor.
2. Relieve pressure in reservoir.
3. Remove plug from reservoir drain line.
4. Drain water from reservoir and discard in approved manner.
5. Fill sample bottle with lubricant.
6. Close valve and replace plug in drain line.
7.
Return compressor to service and check fluid level during operation.
4.5.5
Lubricant Sample Kit
A fluid analysis kit containing a sample bottle, labels and instructions are available from Rogers
Machinery Company, Inc. Contact the Service Department to request part number CLS46-TESTKIT.
Collect a sample from the oil filter element or from the lubricant drain line supplied on the separator tank,
after removing any liquid water and disposing.
