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
VIMPORTANT! Observe all Warning Symbols.
RWARNING! Wear approved eye protection. Wear appropriate Personal Protective Equipment. A full range of Personal Protective
Equipment is available from your Sealey dealer.
Remove personal metallic items such as rings, bracelets, necklaces and watches. A lead-acid battery can produce a short-circuit
current high enough to melt or weld a ring, which would cause severe burns.
Ensure that hands and clothing are clear of fan blades and other moving or hot engine parts. Remove ties and ensure that belts
cannot become entangled.
Ensure that there is another person within hearing distance and is able to come to your aid should a problem arise when working
near a lead-acid battery.
