DIAGNOSTIC MAINTENANCE
PROCEDURES.
2.10.1. How to Perform Diaqnostic Maintenance
Procedures. Paving machine diagnostic procedures are
presented in a logic flowchart. A separate flowchart is
provided for each major system of the machine. In some
procedures separate flowcharts are used to troubleshoot
specific paving machine functions.
Each diagnostic flowchart uses a series of logical steps.
The steps are numbered in sequence, starting with
number "1". Each numbered step presents you with a
diagnostic procedure and a question about the outcome
of the procedure. For each step an INFO KNOWN block
states what is known about the problem at the time. A
POSSIBLE PROBLEMS block indicates what problems
could be causing the malfunction. TEST OPTIONS
presents methods or test equipment available for
performing the procedure. A REASON FOR QUESTION
block states the logic behind the procedure. The basic
information required for troubleshooting is presented in
upper case text.
When performing a diagnostic procedure, start with step
number "1". Perform each step in sequence and answer
the related questions. Each question can be answered
with "YES" or "NO". Based on the "YES" or "NO"
answer, continue through the flowchart until you remedy
the problem or until the problem is referred to the Direct
Support (DS) level of maintenance.
The numbered diagnostic procedures and related
information blocks are always presented on the left hand
page. On the facing right hand page, support
information for use by less experienced personnel is
presented in lower case text. Procedural WARNINGS
and CAUTIONS to be observed are given here. All
personnel shall observe the warning and caution
statements.

maintenance manual.
