Revision 2
• Maintain a record
of
all service performed on the equipment. This record will provide
valuable information
to
assist you in stocking spare parts and scheduling preventive
maintenance.
Note:
A maintenance log form is found in Section 5: PREVENTIVE MAINTENANCE.
B.
Trouble-Shooting Diagnostic Process
The trouble-shooting guide will aid in identifying the probable cause of a malfunction and
establish the most effective corrective action.
The probable causes of each malfunction are listed from the most likely
to
the least likely
to
occur. The corrective action is a condensed, step-by-step summary of the repair procedure
required
to
remedy the problem.
Use the following trouble-shooting diagnostic procedure when a high pressure water jetting
system malfunction occurs:
a.
Precisely define the symptom
of
the problem. This is the most important step in
identifying the probable cause.
b.
Locate the symptom that most closely resembles your appraisal
of
the problem.
c.
Identify the most likely cause.
d.
Follow the corrective action procedure.
If
the symptoms in the chart do not correspond
to
any malfunction in the guide, or if the
problem is not determined or eliminated
by
the corrective action, contact NLB's Customer
Service Department. Refer
to
Section 10: CUSTOMER SUPPORT.
