1. SAFETY INSTRUCTIONS
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
Ensure that there is another person within hearing of your voice and close enough to come to your aid
3
should a problem arise when working near a lead-acid battery.
Wear safety eye protection and protective clothing. Avoid touching eyes while working near battery.
3
Have fresh water and soap nearby in case battery acid contacts skin, clothing or eyes.
3
Wash immediately with soap and water if battery acid contacts skin or clothing. If acid enters eye, flush eye immediately with cool, clean
3
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
3
which is high enough to weld a ring or the like to metal, which would cause severe burns.
Ensure hands, clothing (especially belts) are clear of fan blades and other moving or hot parts of engine, remove ties and contain long hair.
3
DO NOT smoke or allow a spark or flame in the vicinity of battery or engine.

1.2. GENERAL SAFETY INSTRUCTIONS
Familiarise yourself with the application, limitations and potential hazards of the tester. Also refer to the vehicle manufacturer’s handbook.
3
IF IN ANY DOUBT, CONSULT A QUALIFIED VEHICLE TECHNICIAN. For use on lead-acid batteries only.
Ensure that the tester is in good condition before use. If in any doubt do not use the unit and contact an electrician.
3
Use only recommended attachments and parts. To use unapproved items may be dangerous and will invalidate your warranty.
3
Keep tools and other items away from the engine and ensure that you can see the battery and working parts of the engine clearly.
3
Confirm that the battery to be tested is 12 volt and not 6 or 24 volt before attaching clamps to battery terminals.
3
If the tester receives a sharp knock or blow it must be checked by a qualified service agent before being used.
3
If the battery terminals are corroded or dirty, clean them before attaching the clamps.
3
Keep children and unauthorised persons away from the work area.
3
DO NOT disassemble the tester for any reason. The tester must only be checked by qualified service personnel.
7
WARNING! To prevent the risk of sparking, short circuit and explosion DO NOT drop metal tools in the battery area, or allow them to touch
p
the battery terminals.
DO NOT cross-connect leads from tester to battery. Ensure positive (+/RED) is to positive and negative (-/BLACK) is to negative. If the
7
symbols cannot be distinguished, remember that the battery negative terminal is normally the one directly connected to the vehicle bodywork.
DO NOT pull the cables or clamps from the battery terminals.
7
DO NOT use the tester outdoors, or in damp, or wet locations and DO NOT use in the vicinity of flammable liquids or gases.
7
Ensure that there is effective ventilation to prevent a build-up of explosive gases and do not cover or obstruct the tester ventilation louvres.
3
DO NOT use the tester for a task for which it is not designed.
7
When not in use, store the tester carefully in a safe, dry, childproof location.
