Troubleshooting Guide for Units in Service for a Period of Time (Continued)
SYMPTOM
Unit vibrates excessively
Water in discharge air
Oil in discharge air
CAUSE
Loose fasteners
Loose pulley, loose belt or
misalignment or pulleys
Defective pump
Hot humid weather
Water accumulated in the
tank
Restricted intake filter
Wrong type of oil
Worn rings or scored cylinder Replace rings and/or replace cylinder.
Compressor running hot
SOLUTION
This includes mounting bolts for the pump, motor, belt guard, mag.
starter, etc. Check for loose fasteners as part of a routine maintenance
schedule. Tighten any loose fasteners.
The pulley and belt may need to be tightened over time. The pulleys
may need to be realigned to assure proper belt wear and lower
vibration. These should be checked as part of regular maintenance.
A defective pump includes knocking or making noises not normal to
the pump design. Severe oil out the breather usually indicates ring or
cylinder wear. Low pump performance could indicate valve problems.
There are numerous symptoms associated with a defective pump. The
pump will need to be evaluated.
During hot and humid weather it is normal to accumulate water in the
compressor tank. This is normal and requires frequent draining of tank.
We recommend use of an automatic drain along with filters and dryers
if this is a problem.
Drain tank of water to prevent tank corrosion and air tool wear. It is
recommended use of an automatic drain along with filters and dryer to
prevent water into exhaust air of the compressor.
The filter should be changed frequently to avoid possible problems and
to make the compressor operation efficient. There is a vacuum created
in the intake of the compressor, which causes high oil consumption by
pulling oil through the rings. There is also a chance of the intake filter
media being destroyed, allowing contaminants to enter the intake and
cause wear problems.
Do not use SAE-30 automotive type oil. Using the wrong oil can cause
various problems with the pump and will void the warranty. Only use
the oils that the operating manual recommends.
Make sure compressor is running the correct rotation. Compressor
should be clean and in a well ventilated area. Oil should be changed on
regular intervals according to the specifications listed in the manual.
Air filter must be changed as it gets dirty.
