The word WARNING is used to alert you to a procedure, that if not performed properly , might cause personal injury .
1-3. TROUBLESHOOTING T o isolate a malfunction proceed as follows:
1. Clearly define the problem or symptom and when it occurs.
2. Locate the problem in the troubleshooting table.
3. Review all possible causes, then one at a time work through the list of corrections until the problem is solved.
If maintenance procedures ar e not followed correctly , injuries and/or property damage could result.
