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
IMPORTANT! Observe all Warning Symbols.
V
WARNING! Wear approved eye protection. Wear appropriate Personal Protective Equipment. A full range of Personal Protective
R
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.
Have fresh water nearby in case battery acid contacts skin or clothing; flush affected area immediately. If acid enters eyes, flush
immediately with clean running water for a minimum of 15 minutes, seek medical attention.
DO NOT smoke or allow a spark or flame in the vicinity of the 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 hand
book. IF IN ANY DOUBT CONSULT A QUALIFIED ELECTRICIAN.
Ensure that the tester is in good condition before use. If in any doubt do not use the unit and contact a qualified electrician.
Only use recommended attachments and parts. To use unapproved items may be dangerous and will invalidate your warranty.
Keep tools and other items away from the engine and ensure that you can see the battery and working parts of engine clearly.
Determine the system voltage before using the tester.
If the tester receives a sharp knock or blow the unit must be checked by a qualified service agent before using.
Clean battery terminals before using the tester.
Keep children and unauthorised persons away from the work area.
DO NOT disassemble the tester for any reason. The tester must only be checked by qualified service personnel.
WARNING! To prevent the risk of sparking, short circuit and possible explosion DO NOT drop metal tools in the battery area, or allow
R
them to touch the battery terminals.
DO NOT cross-connect tester to battery. Ensure positive (RED) clamp is to positive terminal and negative (black) clamp is to
negative terminal. If battery symbols cannot be distinguished, remember that the negative terminal is the one directly connected to
the vehicle bodywork.
DO NOT use the tester outdoors, or in damp, or wet locations and DO NOT use in the vicinity of flammable liquids or gases.
Ensure there is effective ventilation to prevent a build-up of explosive gases.
DO NOT use the tester for a task for which it is not designed.
When not in use, store the tester carefully in a safe, dry, childproof location.
