Function group structure
The information in the manual is divided in a structure of functions
at different levels, based on the machine's design and use, called
function groups.
The upper level (called main group) determines area, e.g., group 7
Load handling. The second level (called two-digit) determines func-
tion, e.g., 7.2 Lift and lower. The third and fourth levels are used to
break down functions in smaller parts (components).
The function groups' structure for main group and two-digit group
level are common for all machines from Kalmar Industries, e.g., 4.3
Servo brake system. Machine-unique adaptations of functions are
done at the third and fourth group level, e.g., 4.3.9 Wheel brake and
4.3.9.1 Disc pack. This means that certain function groups (headings)
will be left out in the documentation for certain machines since the
machine is missing that specific function or component. In turn, this
means that there may be skips in the function groups' numbering
(e.g., the three-digit heading level 4.8.7 Oil cooler may be included
for some machines, but is missing for others).
The function groups are intended to be used as search terms to find
different types of information between different sections and manu-
als. The information in a function group is divided in smaller sections
according to the type of content, e.g., description or change.
The maintenance manual and Workshop manual contain different in-
formation. The maintenance manual contains only the information
needed for preventive maintenance and simpler troubleshooting.
The Workshop manual contains more in-depth information and re-
pair instructions.
References between sections in the same manual are indicated with
section and group number, e.g., see section
4 Brakes , group 4.3.9
Wheel brake ". References within a section are indicated with page
number, e.g., "see Sensor fuel level, description page 24 ".
References between Maintenance manual and Workshop manual
are not given. If more information is desired for a function group, the
primary recommendation is to search in the same function group in
the other manual. For additional information about where different
information types are found and which references are given, see
References between different information types page 7 .
