SAFETY PRECAUTIONS 

 

  Before using this machine, be sure to read this “SAFTY PRECAUTIONS” and the 

appended “INSTRUCTION MANUAL” carefully for proper operation. 

  After reading through this paper, be sure to keep it in the place exposed to view at all time 

for operators. 

 

Concerning the safety precautions, this paper describes the contents of WARNING by the use 
of the following symbols and signs. 

 

Indicating the contents where a possibility of leading to serious results such as

neglect of this display is conceivable. 

Besides the above, the following WARNING label is affixed to the safety cover (coupling guard) of body coupling unit 

or its vicinity. 

 

The contents given below should always be following since any of them covers important note 
on safety. 

 

WARNING

 

1.  General 

1) 

Never allow any persons other than service engineers to engage in disassembly or repair, or remodeling work. 

2) 

Never work alone and be sure to put on helmet, safety goggles, ear plugs, safety shoes, etc. in conformity with the 

Labor Safety and Health Law, etc. 

3) 

Prior to carrying out any sparking work such as welding, etc., make sure that there are no dangers of fire and 

explosion hazards. 

4) 

Check the place where emission of toxic gas and deficiency of oxygen are conceivable, such as pit, manhole, etc. 

before starting on works and make sure of safety. 

5) 

When carrying out the work for centering check, disassembly, etc., be sure to turn OFF the motor switch and affix a 

tag indicating “NO POWER ON” or the like to the switch so that the switch will not be turned ON by mistake. 

6) 

Before starting on work, be sure to conduct checking of singing outfits such as crane, wire-rope. etc. unfailingly. 

7) 

Install safety fences around the working area and secure an emergency passageway. 

8) 

Since any splits oil on the floor, passageway, etc. may lead to a cause of slippage etc., wipe it off forthwith.
