FOREWORD

Since this machine is large in size, it is divided into some units to meet the transportation
conditions and regulations applied to the transporta­ tion route when shipped from our factory.
This manual describes how to assemble the units into the complete machine in the field.
We hope that this machine will display its quality and you will use it safely according to the
operation manual.
Many units are large in size and heavy in weight and may be handled in a dangerous place or
posture and many workers may have to work together to sling them with cranes.
Accordingly, before starting the assembly work, the work supervisor is required to hold a safety
meeting to oblige the workers to put on pro­ tective gear and appoint a work leader and a crane
work signal man and allot roles to all the workers for safe work.
In particular, the above meeting is more important when worker of dif­ ferent languages and
customs work together.
The following is a reference supervision system diagram.
