OPERATING INSTRUCTIONS

PREPARING TO CHARGE
a. If necessary to remove battery from vehicle to charge, always remove the grounded ter-
minal from battery first. Make sure all accessories in the vehicle are off, so as not to cause
an arc.
b. 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.
c. Clean battery terminals. Be careful to keep corrosion from coming in contact with eyes.
d. Add distilled water in each cell until battery acid reaches level specified by battery manu-
facturer. This helps purge excessive gas from cells. Do not overfill. For a battery without cell
caps, carefully follow manufacturer's recharging instructions.
e. Study all the battery manufacturer's specific precautions such as removing or not remo-
ving cell caps while charging and recommended rates of charge.
f. Determine voltage of battery by referring to car owner's manual and make sure that output
voltage is set at correct voltage. If charger has adjustable charge rate, charge battery initially
at lowest rate.
CHARGER LOCATION
a. Locate charger 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 gravity or filling battery,
d. Do not operate charger in a closed-in area, or restrict ventilation in any way.
e. Do not set a battery on top of charger.
DC CONNECTION PRECAUTIONS
