The Cooling System - ANSThe cooling system should be tested every 6 months to make
sure that it is working correctly.
The water supply control valves should always be open when the air compressor is in
operation.
The Air Intake system - ANSThe air intake filter should be inspected and cleaned weekly. It
should be replaced every 6
months. If at any time the filter is damaged it should be replaced.
The lubrication Oil - ANSThe Certificate of Fitness holder should refer to the manufacturer's
manual to determine the safe
operating temperatures of the lubrication oil. The level of the lubricating oil (lube oil) should
be
checked weekly using the dipstick. The lube oil is designed to lubricate the moving parts on
the
air compressor. The oil used must be of the grade specified by the compressor
manufacturer.
The lube oil should be replaced every six months.

be tested every 3 months. This is tested by
manually draining the oil from the air compressor when it is running. The indictor switch will
shut down the air compressor within a few minutes if it is working correctly. When testing the
compressor in this way, do not run the air compressor for a long period of time. If the switch
is
defective, it should be repaired or replaced. The air
compressor should be refilled with oil before it is used again.

receiver must be drained daily;
however, there is one exception. Do not drain moisture from the air compressor when the
ambient temperature drops below 40 degrees Fahrenheit. This is done by opening the drain
valve and draining off the excess water. All safety valves should be manually operated every
week. This is to ensure that they will function correctly in case of an emergency. It is
recommended that the air receiver tank be pressure tested at a minimum of every 5 years by
a
qualified technician.

frequently by the Certificate of
