DESCRIPTION:

Komatsu PC1250-7 PC1250LC-7 PC1250SP-7 Hydraulic Excavator Field Assembly Instruction Manual

FOREWORD:

• Since this machine is large in size, it is divided into some units to meet the transportation conditions and regulations applied to the transportation 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 protective 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 different languages and customs work together. The following is a reference supervision system diagram. When the work equipment is installed, the engine must be operated.
• Accordingly, before installing the work equipment, inspect and maintain the machine thoroughly. Note that this manual does not describe the whole specification of the machine but describes only the basic specification. If you have any question when dividing and transporting the machine by yourself in future, ask one of our distributors.
