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 any
equipment you intend to use in vicinity of the battery. Review cautionary markings on these products and on the engine.
PERSONAL PRECAUTIONS
13.
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
14.
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.

15. 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.
DC CONNECTION PRECAUTIONS
16.
a.Connect and disconnect the DC output clamps only after setting the charger switches 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.
FOLLOW THESE STEPS WHEN THE BATTERY IS INSTALLED IN A VEHICLE. A SPARK NEAR THE BATTERY
17.
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 switches 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 BATTERY
18.
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, +) 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
use.
GROUNDING AND AC POWER CORD CONNECTION INSTRUCTIONS
19.
The charger should be grounded to reduce the risk of electric shock. This charger is equipped with an electric cord having an equipment
grounding conductor and a grounding plug. The plug must be plugged into an outlet that is properly installed and grounded in accordance with
all local codes and ordinances.
DANGER. Never alter the AC cord or plug provided - if it will not fit the outlet, have a proper outlet installed by a qualified electrician.
Improper connection can result in a risk of an electric shock. This battery charger is for use on a nominal 120-volt circuit, and has a grounding
plug that looks like the plug illustrated in FIGURE (A). A temporary adapter, which looks like the adapter illustrated in FIGURE (C), may be used
to connect this plug to a two-pole receptacle, as shown in FIGURE (B), until a properly grounded outlet can be installed by a qualified
electrician.
DANGER. Before using an adapter as illustrated, be certain
that the center screw of the outlet plate is grounded. The greencolored rigid ear or lug extending from the adapter must be
connected to a properly grounded outlet - make certain it is
grounded. If necessary, replace the original outlet cover plate
screw with a longer screw that will secure the adapter ear or lug
to the outlet cover plate and make ground connection to
grounded outlet.
NOTE:USE OF AN ADAPTER IS NOT ALLOWED IN CANADA. IF A GROUNDING TYPE RECEPTACLE IS NOT AVAILABLE, DO NOT
USE THIS APPLIANCE UNTIL THE PROPER OUTLET IS INSTALLED BY A QUALIFIED ELECTRICIAN.

(CCA rating) and temperature will affect test results - follow instructions carefully.
1.Turn off engine, accessories and battery test equipment.
2.Connect negative (black) clamp to the negative (NEG, N,-) battery post. Connect positive (red) clamp to positive (POS, P, +) battery post.
"Rock" clamps back and forth to insure a good electrical connection.
3.With clamps connected, tester's meter will indicate battery's STATE OF CHARGE. If state of charge is less then 12.4 (6.2) volts ("V"
symbol on meter), the battery should be recharged before load testing. If recharging does not bring voltage to 12.4 (6.2), battery is
defective. If meter needle is off scale to the left, check for loose or reversed clamps; otherwise battery is defective.
4.Note battery's rating in Cold Cranking Amps (CCA). If the rating is not printed on the battery, use the following guidelines to estimate
battery size. Small (4 cyl) -300 CCA; Medium (6 cyl) -400 CCA; Large (8 cyl) -500 CCA.
5.Depress load switch for 10 seconds.
6.Read meter at the end of 10 seconds - with switch depressed. Refer to LOAD TEST ANALYSIS chart.
COMPENSATING FOR LOW TEMPERATURES
Low temperature has a degrading effect on batteries and will affect test results. This can be compensated by reading a different scale.
If battery is 50E, read scale 100 CCA less then battery rating.
If battery is 30E, read scale 200 CCA less than battery rating.
If battery is 10E, read scale 300 CCA less than battery rating.
