CHAPTER 4
Troubleshooting
The troubleshooting guide will help you identify the
probable cause of a malfunction and the most effective
corrective action.
Leakage from weep holes
Water or oil leaking from weep holes give clues to the
condition of intensifier components. Intensifier weep
holes and other locations are identified on the illustra-
tions on the following two pages, with the most proba-
ble cause of failure noted. If leakage is minimal, no
action may be necessary.
The troubleshooting tables in this chapter are keyed to
the weep hole graphics by letter. They provide a more
detailed description of how to troubleshoot using weep
holes, and the necessary corrective actions.
Corrective actions
The corrective action listed on a troubleshooting table is
a condensed summary of the service required to rem-
edy the problem. When you encounter a malfunction:
1. Carefully and precisely define the problem.
2. On the troubleshooting table, locate the symptom
that most closely resembles your assessment of the
problem.
3. Identify the most likely probable cause.
4. Follow the corrective action procedure.
If the symptoms in the chart do not correspond to your
malfunction, or if the problem is not resolved or elimi-
nated by the recommended corrective action, contact
Flow Technical Service.
Other possible malfunctions
At the end of this chapter is a troubleshooting table that
lists intensifier malfunctions that do not exhibit leakage
from weep holes. These are listed in order from most
likely to least likely to occur.
