PROCEDURE
(M/H)
1
VISUAL INSPECTION
0.2
Inspect the compressed air and oil lines for loose connections or leakage.
Tighten loose air connections. Inspect for loose bolts and nuts to tighten as
necessary. Inspect to see that no object obstructs moving parts to prevent
damage.
2
0.1
Check oil level in the oil sump using a dip stick. Add oil as necessary. Check
lubricant reserve and replenish as required. Lubricate angle drive every 300
hours.
3
FUEL
0.1
Check level of gasoline in fuel tank. Fill tank as required.
4
INTERCOOLERS, AFTERCOOLER AND FAN
0.1
Inspect cooling tubes for distortion, dents and loose connections. Check the fan
for dents, bends, looseness or other defects. Correct all defects that impair
operation.
5
Monitor the air compressor continuously during operation. Observe any loose
0.2
fittings or developed leakage. Check for leakage at the control oil tube (nylon)
connectors. Report all defects beyond the scope of operator's maintenance for
subsequent maintenance action, identifying type and location of defect or
deficiency.
6
UNUSUAL NOISES
0.2
In particular, any development of noise from normal operation must be singled
out for investigation. If the noise is severe, or if the defect is detected and
considered detrimental to the unit, stop operation immediately and correct the
cause.
7
UNUSUAL OPERATION
0.1
Detect any vibration, over-heating smoking or any other cause that would
indicate a deviation from acceptable normal operation. Locate and correct the
cause. If the cause of unusual operation cannot be corrected, shut down the
compressor for subsequent maintenance action.
8
VISUAL INSPECTIONS
0.1
Inspect the air compressor for any obvious signs of damage, looseness of wear.
Tighten all loose nuts or bolts. Check for leakage at the control oil tube (nylon)
connectors.
9
PROTECTION
0.1
Store the compressor in a sheltered or enclosed area. Secure the air
compressor in position using the supplied frame assembly tie-down rings as
required.
