  important to read and follow these instructions carefully each time you use the battery tester. Follow these instructions in  

 

  conjunction with those of the battery and vehicle manufacturer, and the maker of any equipment you intend to use in the vicinity of  

  the battery. Remember to review warning marks on all products and on engines.

  specific instructions regarding the use of this type of equipment on each vehicle. No liability will be accepted for damage / injury,    

  where this product is not used in accordance with all instructions.

1.1.    

PERSONAL  PRECAUTIONS

 

9

   Ensure there is another person within hearing range of your voice and close enough to come to your aid, should a problem arise when  

  working near a lead-acid battery.

 

9

   Wear safety eye protection and protective clothing. Avoid touching eyes while working near battery.

 

9

   Have fresh water and soap nearby in case battery acid contacts skin, clothing, or eyes.

 

9

   Wash immediately with soap and water if battery acid contacts skin or clothing. If acid enters eye, flush eye immediately with cool, clean  

  running water for at least 15 minutes and seek immediate medical attention.

 

9

   Remove personal metallic items such as rings, bracelets, necklaces and watches. A lead-acid battery can produce a short-circuit current  

  which is high enough to weld a ring or the like to metal, which would cause severe burns.

 

9

   Ensure hands, clothing (especially belts) are clear of fan blades and other moving or hot parts of engine, remove ties and contain long  

 hair.
