IMPORTANT:

 PLEASE READ THESE INSTRUCTIONS CAREFULLY. NOTE THE SAFE OPERATIONAL REQUIREMENTS, WARNINGS & CAUTIONS. USE 

THE PRODUCT CORRECTLY AND WITH CARE FOR THE PURPOSE FOR WHICH IT IS INTENDED. FAILURE TO DO SO MAY CAUSE DAMAGE AND/OR 
PERSONAL INJURY AND WILL INVALIDATE THE WARRANTY. KEEP THESE INSTRUCTIONS SAFE FOR FUTURE USE.

1.  safety        

 

  DANGER! BE AWARE, LEAD-ACID BATTERIES GENERATE EXPLOSIVE GASES DURING NORMAL BATTERY OPERATION. FOR THIS  

 

  REASON, IT IS VERY IMPORTANT TO READ AND FOLLOW THESE INSTRUCTIONS CAREFULLY, EACH TIME YOU USE THE  

 

 

  BATTERY TESTER. 

 

  Follow these instructions and those published by the battery and vehicle manufacturers, 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.

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.

 

8

  

do not

 smoke or allow a spark or flame in the vicinity of battery or engine.

Also refer to the vehicle manufacturer’s  

  hand book.

IF IN ANY DOUBT CONSULT AN ELECTRICIAN. 

 

9

   ensure the tester is in good order and condition before use. if in any doubt do not use the unit and contact an electrician.

 

9

   only use recommended attachments and parts. to use non-recommended items may be dangerous and will invalidate your warranty.

 

9

   ensure the tester load switch is ‘off’ before attaching/detaching the power clamps to/from the battery  terminals.

 

9

   Keep tools and other items away from the engine and ensure you can see the battery and working parts of engine clearly. 

 

9

   confirm that the battery to be tested is 6 or 12 volt and not 24 volt before attaching clamps to battery terminals.

 

9

   if the tester receives a sharp knock or blow the unit must be checked by a qualified service agent before using.

 

9

   if the battery terminals are corroded or dirty clean them before attaching the clamps.

 

9
