1mm2, 60 meter -1.5mm2.

8. Do not operate charger with damaged cord or plug, replace the cord or plug immediately.

9. Do not operate charger if it has received a sharp blow, been dropped, or otherwise

damaged in any way; take it to a qualified serviceman.

10. Do not disassemble charger; take it to a qualified serviceman when service or repair is
required. Incorrect reassembly may result in a risk of electric shock or fire.

11. To reduce risk of electric shock, unplug charger form outlet before attempting any
maintenance or cleaning. Turning off controls will not reduce this risk.

12. WARNING - RISK OF EXPLOSIVE GASES
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 risk of battery explosion, follow these instructions and those published by
battery manufacturer and manufacturer of any equipment you intend to use in vicinity of
battery. Review cautionary marking on these products and on engine.

13. 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 eye, immediately flood eye 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 battery or engine.
f. Be extra cautious to reduce risk of dropping a metal tool onto battery. It might spark or

short circuit battery or other electrical part that may cause 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 charger for charging a LEAD-ACID battery only. It is not intended to supply power to a
low-voltage electrical system other than in a starter motor application. Do not use 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.

14. PREPARING TO CHARGE
a. If necessary to remove battery from vehicle to charge, always remove the grounded

terminal 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

manufacturer. 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
removing 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 selector switch is set at correct voltage.
If charger has adjustable charge rate, charge battery initially at lowest rate.

15. CHARGER LOCATION
a. Locate charger as far away from battery as dc 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.

16. DC CONNECTION PRECAUTIONS
a. Connect and disconnect dc output clips only after setting any charger switches to off

position and removing ac cord from electric outlet.
Never allow clips to touch each other.
b. Attach clips to battery posts and twist or rock back and forth several times to make a good
connection. This tends to keep the clips from slipping off terminals and helps to reduce risk of
sparking.

17. FOLLOW THESE STEPS WHEN BATTERY IS INSTALLED IN VEHICLE. A SPARK
NEAR BATTERY MAY CAUSE BATTERY EXPLOSION. TO REDUCE RISK OF A SPARK
NEAR BATTERY:
a. Position ac and dc cords to reduce risk of damage by hood, door, or moving engine part.
b. Stay clear of fan blades, belts, pulleys, and other parts that can cause injury to persons.
c. Check polarity of battery posts. POSITIVE (POS, P, +) battery post usually has larger

diameter than NEGATIVE (NEG, N, -) post.
d. Determine which post of battery is grounded (connected) to the chassis. If negative post is
grounded to chassis (as in most vehicles), see item "e". If positive post is grounded to the
chassis, see item "f".
e. For negative-grounded vehicle, connect POSITIVE (RED) clip from battery charger to
POSITIVE (POS, P, +) ungrounded post of battery.
Connect NEGATIVE (BLACK) clip to vehicle chassis or engine block away from battery. Do
not connect clip to carburetor, fuel lines, or sheet metal body parts. Connect to a heavy gage
metal part of the frame or engine block.
f. For positive-grounded vehicle, connect NEGATIVE (BLACK) clip from battery charger to
NEGATIVE (NEG, N, -) ungrounded post of battery. Connect POSITIVE (RED) clip to vehicle
chassis or engine block away from battery. Do not connect clip to carburetor, fuel lines, or
sheet-metal body parts. Connect to a heavy gage metal part of the frame or engine block.
g. When disconnecting charger, turn switches to off, disconnect AC cord, remove clip from
vehicle chassis, and then remove clip from battery terminal.

h. See operating instructions for length of charge information.

18. FOLLOW THESE STEPS WHEN BATTERY IS OUTSIDE VEHICLE. A SPARK NEAR
THE BATTERY MAY CAUSE BATTERY EXPLOSION. TO REDUCE RISK OF A SPARK
NEAR BATTERY:
a. Check polarity of battery posts. POSITIVE (POS, P, +) battery post usually has a larger

diameter than NEGATIVE (NEG, N, -) post.
b. Attach at least a 60cm-long 16mm2 insulated battery cable to NEGATIVE (NEG, N, -)
battery post.

c. Connect POSITIVE (RED) charger clip to POSITIVE (POS, P, +) post of battery.
d. Position yourself and free end of cable as far away from battery as possible - then connect

NEGATIVE (BLACK) charger clip to free end of cable.

e. Do not face battery when making final connection.
f. When disconnecting charger, always do so in reverse sequence of connecting procedure

and break the first connection while as far away from 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.

19. AC POWER CORD CONNECTION INSTRUCTIONS

The plug must be plugged into an outlet that is properly installed in accordance with all local
codes and ordinances.
DANGER. Never alter AC cord or plug provided - if it will not fit outlet, have 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 110-volt circuit.

20. LENGTH OF CHARGE

The following instruction will allow you to determine how long it will take to bring a specific
battery to full charge.
a. Test the battery for state of charger with a hydrometer or electronic percent-of-charge

tester.
b. Determine the size of the battery in Amp-Hour or Reserve Capacity. If the ratings are not
printed on the battery, contact your local battery dealer for this information. These are the
only ratings that can be used to determine length to charging time.
c. Use the battery rating, the charge level of the battery, and amp setting to be used on the
charger in the formula provided below.

Amp Hour Rating of Battery × Percent of Charged Needed
