A35 FDNY EXAM/9 QUESTIONS AND ANSWERSThe Cooling System - -The 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 - -The 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 - -The 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.
-The Automatic low-level Inidicator - -The automatic low-level oil indicator
switch should 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.
-The air receiver - -Water builds up in the moisture separator assembly and
the air 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.
