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 THIS PIECE OF EQUIPMENT.
Follow these instructions and those published by the battery
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.
,
Observe standard workshop safety procedures when using the
 Memory Master.
Ensure there is another person within hearing range, or
close enough to come to your aid when working near, or with,
 lead-acid batteries.
Wear safety eye protection and protective clothing. Avoid
 touching eyes while working with or near a battery.
Have fresh water and soap nearby in case battery acid contacts
 skin, clothing or eyes.
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.
Remove personal metallic items such as rings, bracelets,
necklaces and watches. A lead-acid battery can produce a
short-circuit current high enough to weld a ring or the like to
 metal, which may cause severe burns.
Ensure hands, clothing (especially belts) are clear of fan blades
and other moving or hot parts of engine, remove tie and contain
 long hair.
Keep the work area clean and uncluttered and ensure there is
adequate lighting. Keep tools and other items away from the
engine and ensure you can see the battery and working parts of
 engine clearly. 
Maintain correct balance and footing. Ensure the floor is not
 slippery and wear non-slip shoes.
Keep children and unauthorised persons away from the working
 area.
WARNING! DO NOT use tester where there are flammable
 gases or liquids (especially petrol and diesel). 
WARNING! DO NOT use tester on any vehicles other than those
 with 12 Volt DC systems.
DO NOT smoke or allow a spark or flame in the vicinity of battery or
 engine.
DO NOT dis-assemble tester. The tester must be checked by
 qualified service personnel only.
DO NOT get tester wet or use in damp or wet locations or areas
 where there is condensation.
DO NOT use the tester for any purpose other than that for which
 it is designed.
DO NOT pull the cables or clamps from the battery terminals.
