INTRODUCTION :
- Most accidents happen due to the disregard of basic safety rules and precautions. To prevent accidents from happening, the factors that cause them must be avoided beforehand. Before operating this machine, carefully read this manual so that you fully understand the safety precautions and the proper procedures and instructions for inspection and maintenance. Performing maintenance and repair without adequate knowledge can cause accidents.
- A manual cannot cover every possible cause of an accident, so you also need to take precautions for items not mentioned in this SERVICE MANUAL-Chassis & Mast. It is especially important to do repair and maintenance work not covered in this manual under the direction of an instructor experienced at the task being performed.
Using this “SERVICE MANUAL-Chassis & Mast” :
- This manual has information about the layout and names of main components, explains disassembly, assembly, inspection, adjustment, and maintenance procedures, and contains troubleshooting hints that apply mainly to the model EP-TCB.
- It is important to note that in order to improve quality, performance, and safety parts used in this forklift truck are subject to change and that some portions of the contents and illustrations in the SERVICE MANUAL-Chassis & Mast at the time of printing may not be identical due to these changes.
