Troubleshooting, general work
instructions
When troubleshooting, it's important that the work is structured and
logical. The point of the troubleshooting described in the mainte-
nance manual is to exclude components as error source so that the
real error source can be pin-pointed. A proposal for structured work
method is described below.
When troubleshooting, it's important to understand how the ma-
chine functions, certain malfunctions can be pin-pointed directly us-
ing function descriptions. In the sections 0–12 there are descriptions
of the machine's different functions.

Troubleshooting with error code, example page 5.
In the error code lists there are recommended actions for every
error code. Error code lists are found in section D Error codes.
5 If there is no error code, or problem remains, use the function
description for function in question in section 0–12.
In the function description there's information about which
components are involved in the function and how these com-
ponents work together. In certain cases, there's information
about which conditions apply to enable activation of the func-
tion. Measuring points are marked with flags (C for pressure
check connections, D for diagnostic menu).
