Every rental store owner knows that preventive maintenance can save money. This is especially true with compressors. Here are tips to help increase the productivity of your compressors:

• Check oil and fluid levels daily.

• Change compressor oil/fluids every 500 hours on small machines (up to 600 cubic feet per minute), 1,000 hours on large machines (750 cfm and above).

• Change air filters after 500 hours of use.

• Replace the separator element after 1,000 hours of operation, 2,000 hours on large machines. The separator is important because it prevents excessive oil use.

• All hoses should be checked regularly and replaced if they appear worn, cracked or damaged.

• Overhaul or exchange the airend between 8,000 and 10,000 hours. This usually depends on how effectively the machine has been maintained.

• Clean the fuel tank annually.

• Make sure the heat exchangers are clean to reduce operating temperature.

• Check fasteners and ensure they are tightly secured.

• Test the safety shutdown system monthly. This will ensure machine protection against high temperatures and low engine oil pressure.
