SAFETY PRECAUTIONS FOR WORKING IN THE VICINITY OF A BATTERY
1) Batteries generate explosive gases during normal operation. Use in well-ventilated area.
2) Consider having someone close enough or within the range of your voice to come to your aid when you
work near a battery.
3) Do NOT smoke, strike a match, or cause a spark in vicinity of battery or engine. Avoid explosive gas,
flames and sparks.
4) Remove all personal jewelry, such as rings, bracelets, necklaces, and watches while working with a
vehicle battery. These items may produce a short-circuit that could cause severe burns.
5) Be extra cautious to reduce risk of dropping a metal tool onto the battery. It might spark or short-circuit
a battery or other electrical hardware which may cause an explosion or fire.
6) Wear complete eye protection, hand and clothing protection. Avoid touching eyes while working near a
battery.
7) Study all battery manufacturer’s specific precautions such as removing or not removing cell caps while
charging and recommended rates of charge.
8) Clean battery terminals before connected with the charger. Be careful to keep corrosion from coming in
contact with eyes.
9) When it is necessary to remove a battery from vehicle to charge, always remove grounded terminal from
battery first. Make sure all accessories in the vehicle are off in order to prevent an arc.
10) It is NOT intended to supply power to an extra-low-voltage electrical system or to charge dry-cell
batteries. Charging dry-cell batteries may burst and cause injury to persons and property.
11) NEVER charge a frozen, damaged, leaking or non-rechargeable battery.
12) If battery electrolyte contacts skin or clothing, wash immediately with soap and water. If electrolyte
enters eye, immediately flood eye with running clean cold water for at least 15 minutes and get medical
attention immediately.
SAFETY PRECAUTIONS FOR USING THE CHARGER
1) Do NOT place the charger in the engine compartment or near moving parts or near the battery; place as
far away from them as DC cable permits. NEVER place a charger directly above a battery being charged;
gases or fluids from battery will corrode and damage charger.
2) Do NOT cover the charger while charging.
3) Do NOT expose to rain or wet conditions.
4) Connect and disconnect DC output only after setting AC cord from electric outlet.
5) Use of an attachment not recommended or sold by the manufacturer may result in a risk of fire, electric
shock or injury to persons.
6) Do not overcharge batteries by selecting the wrong charge mode.
