Sakai TW352 - User Manual

PREFACE
Generally, rollers tend to come large-sized and find their applications in
dangerous fields such as rough terrain, steep slopes or slippery areas. Faulty
rollers may risk a grave accident.
For purpose-built rollers to negotiate problem terrain with the ultimate in
performance maintained free from failure over the longest possible period of
time, adequate handling and regular preventive maintenance recommended
are of prime importance. If a trouble developes, it should be effectively
corrected with proper safety measures taken.
This service manual is intended to serve as a guide particularly for
maintenance personnel to perform quality service by gaining working
knowledge of and reliable maintenance techniques for machines in question.
Included in this literature are descriptions of SPECIFICATIONS, STRUCTURE
& OPERATION, INSPECTION & ADJUSTEMNT, FAULT DIAGNOSIS and
DISASSEMBLY & ASSEMBLY. Systematic explanations are being given to
each of these five cathegories in this sequence.
Rollers principally concern qualitative factors as represented by ‘compaction
density’, to say nothing of quantitative elements like ‘productivity’.
SPECIFICATIONS section includes performance data of major significance
e.g. ‘vibratory frequency’ to be checked when servicing machines in question.
For reasonable maintenance services, it is a precondition to know the vital
portions of machines in question and how they work. Referring to relevant
electric wiring and hydraulic circuit diagrams, STRUCTURE & OPERATION
instructs location of key units and function of systems into which the key units
are assembled.
