repair is required. Incorrect reassembly may result in risk of electric shock or fire.
11. To reduce the risk of electric shock, unplug the charger from the outlet before attempting any maintenance or cleaning. Turning off the
controls will not reduce this risk.
WARNING - RISK OF EXPLOSIVE GASES
12.
a. WORKING IN VICINITY OF A LEAD-ACID BATTERY IS DANGEROUS. BATTERIES GENERATE EXPLOSIVE GASES DURING
NORMAL BATTERY OPERATION. FOR THIS REASON IT IS OF UTMOST IMPORTANCE THAT EACH TIME BEFORE USING YOUR
CHARGER, YOU READ THIS MANUAL AND FOLLOW THE INSTRUCTIONS EXACTLY.
b. To reduce the risk of battery explosion, follow these instructions and those published by the battery manufacturer and manufacturer of
13.
14.
15.
any equipment you intend to use in vicinity of the battery. Review cautionary markings on these products and on the engine.
PERSONAL PRECAUTIONS
a. Someone should be within range of your voice or close enough 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.
d. If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enter eyes, immediately flood eyes with running
cold water for at least 10 minutes and get medical attention immediately.
e. NEVER smoke or allow a spark or flame in vicinity of the battery or engine.
f. Be extra cautious to reduce risk of dropping a metal tool onto the battery. It might spark or short-circuit the battery or other electrical parts
that may cause an explosion.
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. Use this 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 this 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.
i. NEVER charge a frozen battery.
PREPARING TO CHARGE
a. If necessary to remove battery from vehicle to charge, always remove the grounded terminal from the battery first. Make sure all
accessories in the vehicle are off, so as not to cause an arc.
b. Be sure the area around the battery is well ventilated while the 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 the 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 the battery manufacturer. This helps purge excessive gas
from cells. Do not overfill. For a battery without cell caps, carefully follow the manufacturer's recharging instructions.
e. Study all battery manufacturer's specific precautions such as removing or not removing the cell caps while charging and the
recommended rates of charge.
f.Determine voltage of the battery by referring to the car owner's manual and make sure that the output voltage selector switch is set at the
correct voltage. If the charger has adjustable charge rate, charge the battery initially at the lowest rate.
CHARGER LOCATION
a. Locate the charger as far away from the battery as the DC cables permit.
b. Never place the charger directly above the battery being charged; gases from the battery will corrode and damage the charger.
c. Never allow battery acid to drop on the charger when reading the specific gravity or filling battery.
d. Do not operate the charger in a closed-in area, or restrict ventilation in any way.
e. Do not set a battery on top of the charger.
IMPORTANT SAFETY INSTRUCTIONS

16. DC CONNECTION PRECAUTIONS
a. Connect and disconnect the DC output clamps only after setting the charger switch to the OFF position and removing the AC cord from
the electric outlet. Never allow the clamps to touch each other.
b. Attach the DC clamps to the battery post and twist or rock back and forth several times to make a good connection. This tends to keep
the clamps from slipping off the terminals and helps to reduce the risk of sparking.
17.
FOLLOW THESE STEPS WHEN THE BATTERY IS INSTALLED IN A VEHICLE. A SPARK NEAR THE
BATTERY MAY CAUSE A BATTERY EXPLOSION. TO REDUCE THE RISK OF A SPARK NEAR THE
BATTERY:
a. Position the AC and DC cords to reduce the risk of damage by the hood, door, or moving engine parts.
b. Stay clear of fan blades, belts, pulleys, and other parts that can cause injury to persons.
c. Check the polarity of the battery post. The POSITIVE (POS, P, +) battery post usually has a larger diameter than the NEGATIVE (NEG,
N, -) post.
d. Determine which post of the battery is grounded (connected) to the chassis. If the negative post is grounded to the chassis (as in most
vehicles), see item "e". If the positive post is grounded to the chassis, see item "f".
e. For negative-grounded vehicles, connect the POSITIVE (RED) clamp from the battery charger to the POSITIVE (POS, P, +) ungrounded
post of the battery. Connect the NEGATIVE (BLACK) clamp to the vehicle chassis, heavy gauge metal part of the frame, or engine block,
away from the battery. Do not connect to the carburetor, fuel lines, or sheet metal body parts.
f.For positive-grounded vehicles, connect the NEGATIVE (BLACK) clamp from the battery charger to the NEGATIVE (NEG, N, -)
ungrounded post of the battery. Attach the POSITIVE (RED) clamp to the vehicle chassis or engine block away from the battery. Do not
connect the clamp to the carburetor, fuel lines, or sheet-metal body parts.
g. When disconnecting the charger, turn the switch to OFF, disconnect the AC cord, remove the clamp from the vehicle chassis, and then
remove the clamp from the battery terminal.
h. See the operating instructions for length of charge information.
FOLLOW THESE STEPS WHEN THE BATTERY IS OUTSIDE THE VEHICLE. A SPARK NEAR THE
18.
BATTERY MAY CAUSE BATTERY EXPLOSION. TO REDUCE THE RISK OF A SPARK NEAR THE
BATTERY:
a. Check the polarity of the battery post. The POSITIVE (POS, P, +) post usually has a larger
diameter than the NEGATIVE (NEG, N, -) post.
b. Attach at least a 24 inch long 6-gauge (AWG) insulated battery cable to the NEGATIVE (NEG, N, -
) battery post.
c. Connect the POSITIVE (RED) charger clamp to the POSITIVE (POS, P, +) post of the battery.
d. Position yourself and the free end of the cable as far away from the battery as possible, then
connect the NEGATIVE (BLACK) charger clamp to the free end of cable.
e. Do not face the battery when making the final connection.
f. When disconnecting the charger, always do so in reverse sequence of connecting procedure, and break the first connection while
standing as far away from the battery as practical.
g. A marine (boat) battery must be removed and charged on shore. To charge it on board requires equipment specially designed for marine
19.
use.

12V CRANKING ASSIST
Turn off all the lights and accessories in the stalled vehicle.
Connect the charger to the battery per previous instructions.
Set the CHARGE VOLTAGE switch to the 12HI position.
Charge the battery on 12HI for at least five minutes. Make sure the battery is accepting current before setting charger to 12V START.
Set the switch in the 12V START position. Start the vehicle with the charger connected to the battery.
NOTE: Do not crank the engine more than 20 seconds in any five minute period; excessive cranking may overheat and damage the starter.
DO NOT USE THE 12V START POSITION TO CHARGE BATTERIES.
If the vehicle fails to start, return the CHARGE VOLTAGE switch to the 12HI position.
While waiting for the starter to cool, allow the charger to continue to charge the battery.
Turn the timer to the OFF position before disconnecting the clamps.
CHARGING SULFATED BATTERIES
If your battery has sat in the discharged state for an extended period of time, it can become SULFATED. This usually is seen as a white deposit
near the top of the battery. The sulfate is formed when a battery with low water levels remains discharged for an extended time. Sulfated batteries
exhibit the characteristic of accepting no charge regardless of the rate of charge.
The charging method is two staged. The first stage of attempting to break down the sulfation to allow the battery to accept a charge must be closely
watched to avoid excessive charge rates as the battery begins to charge and overheat. The second stage is a slow charging to restore the battery
to full charge.
READ AND FOLLOW ALL PRECAUTIONS AND WARNINGS IN YOUR INSTRUCTION MANUAL BEFORE ATTEMPTING TO CHARGE
SULFATED BATTERIES. FAILURE TO OBSERVE THESE WARNINGS MAY RESULT IN PROPERTY DAMAGE OR SERIOUS PERSONAL
INJURY OR DEATH.
To recharge a sulfated battery:
1. Attach the battery clamps as described in the instruction manual.
2. Always use the charger’s lowest rate when turning the charger on. Set the charger to the charger’s highest rate for the voltage of the battery
being charged.
CAUTION: NEVER CHARGE A BATTERY AT VOLTAGE RATES ABOVE THAT OF THE BATTERY.
3. The battery will show little or no amperage at the start of the charging process. This will continue until the sulfation begins to break down.
CAUTION: AS THE SULFATION BREAKS DOWN, THE AMPERAGE MAY RAPIDLY RISE. CONSTANT
ATTENTION MUST BE OBSERVED TO PREVENT SERIOUS OVERHEATING OF THE BATTERY.
4. Lower the charge rate to the lowest rate for the voltage of battery being charged.
5. Charge the battery at this low rate until the electrolyte reaches the fully charged state as described in the tables in your instruction manual.
This may take as long as two or three days.
NOTE: SOME BATTERIES MAY BE SO BADLY SULFATED THEY CAN NOT BE RESTORED TO A NORMAL OPERATING CONDITION,
REGARDLESS OF THE RATE OF CHARGE OR THE LENGTH OF TIME THE CHARGE IS APPLIED. IF THE BATTERY CANNOT BE
RESTORED TO A FULLY CHARGED CONDITION BY A SLOW CHARGING, IT SHOULD BE REPLACED.
