PERSONAL PRECAUTIONS
-
Consider having someone close enough by to come to your aid when you work near a lead-acid battery.
b.Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing, or eyes.
c.Wear complete eye protection and clothing protection. Avoid touching eyes while working near battery. -
If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters eye, immediately flood eye with running cold water for at least 10 minutes and get medical attention immediately.
- NEVER smoke or allow a spark or flame in vicinity of battery or engine.
- Be extra cautious to reduce risk of dropping a metal tool onto battery. It might spark or short-circuit battery or other electrical part that may cause explosion.
- Remove personal metal items such as rings, bracelets, necklaces, and watches when working with a lead-acid battery. A lead-acid battery can produce a short-circuit current high enough to weld a ring or the like to metal, causing a severe burn.
- Use Maintainer for charging Gel, LEAD-ACID orAbsorbed Glass Mat (AGM) batteries only. It is not intended to supply power to a low voltage electrical system other than in a starter-motor application. Do not use battery Maintainer for charging dry-cell batteries that are commonly used with home appliances. These batteries may burst and cause injury to persons and damage to property.
- NEVER charge a frozen battery.
-
PREPARING TO CHARGE
- If necessary to remove battery from vehicle to charge, always remove grounded terminal from battery first. Make sure all accessories in the vehicle are off, so as not to cause an arc.
- Be sure area around battery is well ventilated while battery is being charged.
-
Clean battery terminals. Be careful to keep corrosion from coming in contact with eyes.
- Add distilled water in each cell until battery acid reaches level specified by battery manufacturer. Do not overfill. For a battery without removable cell caps, such as valve regulated lead acid batteries, carefully follow manufacturer’s recharging instructions.
- Study all battery manufacturer’s specific precautions while charging and recommended rates of charge.
- Determine voltage of battery by referring to vehicle owner’s manual and make sure it matches output rating of battery Maintainer.
- not place Maintainer or electrical connections on ground or floor.
-
MAINTAINER LOCATION
