2. To reduce risk of battery explosion, follow these instructions and those published by
battery manufacturer and manufacturer of any equipment you intend to use in vicinity of
battery. Review cautionary marking on these products and on engine.
C. PERSONAL PRECAUTIONS
1. Someone should be within range of your voice or close enough to come to your aid
when you work near a lead-acid battery.
2. Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing
or eyes.
3. Wear complete eye protection and clothing protection. Avoid touching eyes while
working near battery.
4. 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.
5. NEVER smoke or allow a spark or flame in vicinity of battery or engine.
6. Be extra cautious not to drop a metal tool onto battery. It might spark or short circuit
battery or other electrical part that may cause explosion.
7. 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.
8. Use charger for charging a LEAD-ACID battery only. It is not intended to supply power
to a low-voltage electrical system other than in an automotive application. Do not use
battery charger 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.
9. NEVER charge a frozen battery.
D. PREPARING TO CHARGE
1. 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.
2. Be sure area around battery is well ventilated while battery is being charged. Gas can
be forcefully blown away by using a piece of cardboard or other non- metallic material
as a fan.
3. Clean battery terminals. Be careful to keep corrosion from coming in contact with eyes.
4. Add distilled water In each cell until battery acid reaches level specified by battery
manufacturer. This helps purge excessive gas from cells. Do not overfill. For a battery
without cell caps, carefully follow manufacturers recharging instructions.
5. Study all battery manufacturers specific precautions such as removing or not removing
cell caps while charging and recommended rates or charge.
6. Determine voltage of battery by referring to car owner’s manual and make sure that
output voltage selector switch is set at correct voltage. If charger has adjustable charge
rate, charge battery initially at lowest rate.
E. CHARGER LOCATION
1. Locate charger as far away from battery as DC cables permit.
2. Never place charger directly above battery being charged; gases from battery will
corrode and damage charger.
3. Never allow battery acid to drip on charger when reading gravity or filling battery.
4. Do not operate charger in a closed-in area or restrict ventilation in any way.
5. Do not set a battery on top of charger.
6. Do not expose chuger to rain or snow.
F. DC CONNECTION PRECAUTIONS
1. Connect and disconnect DC output clips only after setting any chuger switches to off
