Section 2 is the removal/installation
procedures for the frame covers which are
subject to higher removal/installation
frequency during maintenance and
servicing operations.

Section 3 describes the inspection/
adjustment procedures, safety rules and
service information for each part, starting
from periodic maintenance.

Sections 5 through 12 give instructions
for disassembly, assembly and adjustment
of engine parts. Section 13 is the removal/
installation of chassis. Section 15 states
the testing and measuring methods of
electrical equipment.

Most sections start with an assembly or
