g) 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.
h) Charger is designed to be used for recharging lead acid batteries. Never
use it to power a low voltage electrical system, or for attempting to
recharge dry cell batteries that are commonly used in house holds. These
batteries may explode and cause injury to persons and damage property.
Never ccharge aa ffrozen bbattery oor aa bbattery aat aa ttemperature aabove
123° FF.
a) If necessary to remove battery from equipment to charge, always remove
ground terminal first. Turn off all accessories in the vehicle, so as not to
cause an arc.
b) Be sure area around battery is well ventilated while battery is being
charged. Gas vapors can be forcefully blown away by using a piece of non-
metallic material as a fan.
c) Clean battery terminals. Be careful to keep corrosion from contacting eyes.
d) Add distilled water to each cell until battery acid reaches level specified by
the manufacturer. This helps Purge excessive gas from cells. Do not overfill.
For a battery with out cell caps, follow manufacturer's recharging instruc-
tions.
e) Study all battery manufacturer's specific instructions such as removing cell
caps while charging and recommended charge rates.
f) Determine voltage of battery by referring to equipment owner's manual and
make sure that charger output voltage is correct.
Charger LLocation
a) Make sure charger is as far away from battery as output cables permit.
b) Never place charger directly above battery being charged; gases from battery
will corrode and damage charger.
c) Never allow battery acid to drip on charger when reading specific gravity or fill-
ing.
d) Do not operate charger in a closed-in area or restrict ventilation in any way.
e) Do not set battery on top of charger.

Connection P
Precautions
a) Connect and disconnect DC output clips only after removing charger from
outlet.
b) Never allow clips to touch each other.
c) Attach clips to battery posts and twist or rock back and forth several times to
make good contact. This keeps clips from slipping off terminals and reduces
risk of sparking.
