TROUBLESHOOTING
In servicing equipment which has malfunctioned, it
is very important to:
1. DEFINE the problem and accurately determine
what is the malfunction.
2. Determine the BASIC CAUSE.
3. ELIMINATE the cause and repair the
malfunction (obviously, if the cause is not
properly identified and eliminated, the
malfunction may recur).
It is usually relatively easy to define the malfunc-
tion, but sometimes very difficult to spot the cause.
If the problem remains after following the sug-
gestions listed, contact Wells Manufacturing
Company at (702) 345-0444.
