Safety

[1] Before starting maintenance work, read carefully and fully understand materials (instruction manual and maintenance manual).
[2] Before disassembling and assembling, take sufficient safety measures to prevent accidents such as falling loads, being caught in or under the machine and burns. When working under the machine, use safety blocks to support the machine to avoid workers getting caught.
[3] Cranes and other hoist equipment must be operated by licensed operators.
1) Crane operators and slinging workers must be licensed.
2) Make sure to inspect rigging.
[4] Wear proper clothing and protective gear as necessary during inspection or maintenance (safety shoes, helmets, protective goggles, gloves, earplugs, dust mask and other protective devices).
[5] Always keep the work area clean to avoid accidents such as skidding during travel and falling objects.
[6] Make sure to ventilate properly when inspecting or servicing a machine indoors.
[7] Be prepared for any emergencies and take necessary fire preventative measures

Introduction

• Appropriate operations, maintenance, inspections, troubleshooting, and repair of the machine are vital
  to keep it performing at its best and for the longest possible period of time, and to prevent it from breaking
  down.
• This document includes a General Outline, Specifications (Performance), Troubleshooting and Disassembly/
  maintenance instructions, which are necessary for inspection, troubleshooting and repair of the
  machine.
  (Note: This Shop Manual is to be filed with the additional information to be added later.)
• For details of the engine, refer to the maintenance manual published by the engine manufacturer.
• For daily inspections and maintenance, see the Operator’s Manual to take advantage of the machine’s
  full performance.
• Numerical values or others may be changed without notice due to design alterations or other reasons.
