4. PREPARING TO CHARGE BATTERY
4.1 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.
4.2 Be sure area around battery is well-ventilated while battery is being charged. Gas can be force-
fully blown away by using a piece of cardboard or other nonmetallic material as a fan.
4.3 Clean battery terminals. Be careful to keep corrosion from coming into contact with your eyes.
. Add distilled water in each cell until battery acid reaches level specified by manufacturer. This
helps purge excessive gas from cells. Do not overfill. For a battery without caps, carefully follow
the manufacturer’s recharging instructions.
. Study all battery manufacturer’s specific precautions such as removing or not removing cell caps
while charging and recommended rates of charge.
4.6 Determine voltage of battery by referring to car owner’s manual, and make sure that it matches
the output rating of the charger.
5. CHARGER LOCATION
5.1 Locate the NAPA Digital Wheel Charger as far away from battery as charger cables permit.
5.2 Never place charger directly above battery being charged; gases from battery will corrode and
damage charger.
. Never allow battery acid to drip on the charger when taking gravity readings or filling a battery.
5.4 Operate charger only in a well-ventilated area, free of dangerous vapors.
5.5 Store charger in a safe, dry location and maintain in perfect condition.
5.6 Do not set battery on top of charger, or where its acid might drip onto the charger.
6. DC CONNECTION PRECAUTIONS
6.1 All switches should be set in
OFF position and AC cord should be UNPLUGGED from electrical
outlet before you connect and disconnect charger clamps.
6.2 Never allow clamps to touch each other.
6.3 When attaching charger clamps, be certain to make the best possible mechanical as well as elec-
trical connection. This will tend to prevent clamps from slipping off connections, avoid dangerous
sparking, and assure safer and more efficient charging. Clamps should be kept clean.
CAUTION: SETTING SWITCHES TO OFF DOES NOT ALWAYS DISCONNECT CHARGER
ELECTRICAL CIRCUIT FROM AC POWER CORD OR DC CHARGER CLAMPS. MAKE SURE
CHARGER IS UNPLUGGED AND UNCLAMPED WHENEVER IT IS NOT IN USE.
