General precautions 

Inappropriate handling causes an extreme danger. Read and understand what is described in the operation and maintenance manual before operating the machine. Read and understand what is described in this manual before starting the work.

• Before performing any greasing or repairs, read all the safety labels stuck to the machine. For the locations of the safety labels and detailed explanation of precautions, see the operation and maintenance manual.
• Locate a place in the repair workshop to keep the tools and removed parts. Always keep the tools and parts in their correct places. Always keep the work area clean and make sure that there is no dirt, water or oil on the floor. Smoke only in the areas provided for smoking. Never smoke while working.
• When performing any work, always wear the safety shoes and helmet. Do not wear loose work cloths, or clothes with buttons missing. 1. Always wear the protective eyeglasses when hitting parts with a hammer. 2. Always wear the protective eyeglasses when grinding parts with a grinder, etc.
• When performing any work with 2 or more workers, always agree on the working procedure before starting. While working, always keep conversations of the work between your fellow workers and your self on any step of the work. During the work, hang the warning tag of “UNDER WORKING” in the operator’s compartment.
• Only the approved personnel can do the work in a closed environment or in a prohibited area.
• Only qualified workers must perform the work and operation which require license or qualification.
• Keep the tools in good condition. And learn the correct way to use the tools, and use the proper ones among them. Before starting the work, thoroughly check the tools, lift truck, service vehicle, etc.
• If welding repairs is required, always have a trained and experienced welder with good knowledge of welding perform the work. When performing welding work, always wear welding gloves, apron, shielding goggles, cap, etc.
• Before starting work, warm up your body thoroughly to start work under good condition.
• Avoid continuing work for long hours and take rests with proper intervals to keep your body in good condition. Take a rest in a specified safe place.
• When you work in high places, use a platform.
• Before you start the work, use the personal fallarrest equipment to prevent falling. There is a danger of personal accident that you fall by slipping.
• Always do the work correctly. If you find the unsafe behavior of co-worker, give him/her a notice and stop it. • Because there is a danger that you are caught, be very careful when the work is done in dangerous areas such as: when you go in the range where the lifted load possibly falls, or when you stand directly in front of tire, or when you are near the sliding parts.
