WARNING:This product contains chemical known to the state of California to cause
cancer or reproductive toxicity.
1. SAVE THESE INSTRUCTIONS – This manual
contains important safety and operating instructions for battery charger model
US 3300 Corvette (model 1051).
2. Do not expose charger to rain or snow.
3. Use of an attachment not recommended or sold by CTEK may result in a risk
of fire, electric shock or serious injury to persons.
4. To reduce risk of damage to electric plug and cord, pull by the plug rather than
by the cord when disconnecting charger.
5. An extension cord should not be used unless absolutely necessary. Use of
an improper extension cord could result in a risk of fire and electric shock. If
extension cord must be used, make sure:
a) That pins on plug of extension cord are the same number, size and shape as
those of plug on charger;
b) That extension cord is properly wired and in good electrical condition; and
c) That wire size is large enough for AC ampere rating as specified in “RECOM-
MENDED MINIMUM AWG SIZE FOR EXTENSION CORDS”.
6. Do not operate charger with a damaged cord or plug – replace the cord or plug
immediately.
7. Do not operate the charger if it has received a sharp blow, been dropped or
otherwise damaged in any way; take it to a qualified serviceman.
8. Do not disassemble the charger; take it to a qualified serviceman when service
or repair is required. Incorrect reassembly may result in a risk of electrical
shock or fire.
9. To reduce risk of electric shock, unplug charger from AC outlet before attempt-
ing any maintenance or cleaning. Turning off controls will not reduce the risk.

10. WARNING - RISK OF EXPLOSIVE GASES
a)WORKING IN VICINITY OFALEAD-ACID
BATTERY IS DANGEROUS. BATTERIES
GENERATE EXPLOSIVE GASES DURING
NORMAL BATTERY OPERATION. FOR
THIS REASON, IT IS OF THE UTMOST
IMPORTANCE THAT YOU FOLLOW THE
INSTRUCTIONS EACH TIME YOU USE
THE CHARGER.
b) To reduce risk of battery explosion, follow these instructions and those pub-
lished by the battery manufacturer and the manufacturer of any equipment
you intend to use in vicinity of battery. Review cautionary marking on these
products and on engine.
11. PERSONALPRECAUTIONS
a) Consider having someone 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) Always 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 enters 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 lead-acid battery.Alead-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 12 V device. Do not use battery charger for dry-cell batteries
4 EN
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.
12. PREPARING TO CHARGE
a) 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.
b) Be sure area around battery is well ventilated while battery is being charged.
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. Do not overfill. For a battery without removable cell
caps, such as valve regulated batteries, carefully follow battery manufacturer’s
recharging instructions.
e) Study all battery manufacturer’s specific precautions while charging and rec-
ommended 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.
13. CHARGER LOCATION
a) Locate charger as far away from battery as DC cables permit.
b) Never place charger directly above battery being charged; gasses from battery
will corrode and damage the charger.
c) Never allow battery acid to drip on charger when reading specific 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 to of the charger.
14. DC CONNECTION PRECAUTIONS
a) Connect and disconnect DC output (APO, Auxilary Power Outlet, cig plug) to
vehicle after removingAC cord from electric outlet.

15. FOLLOW THESE STEPS WHEN BATTERY
IS INSTALLED IN VEHICLE.ASPARK
NEAR BATTERY MAY CAUSE BATTERY
EXPLOSION. TO REDUCE RISK OF A
SPARK NEAR BATTERY:
a) PositionAC and DC cords in a position that will reduce the 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.
IMPORTANT SAFETYINFORMATION!
The US 3300 Corvette (model 1051) cannot be used to restore a fully worn out bat-
tery. If the US 3300 Corvette (model 1051) does not switch to maintenance charge
after three days (green light illuminated), there is a fault. Possible causes:
• The battery is probably worn out and should be replaced.
• Some large antimony batteries may behave different and can allow the
US 3300 Corvette (model 1051) to charge the battery for too long, which can lead
to overcharging. See caution!
• If heavy power consumers like fitted alarms and navigation computers are con-
nected to the battery, the charging process takes longer and this can also over-
charge the battery.
• A sulfated battery will only accept current with difficulty, and consequently the
charging process takes a particularly long time.Aworn out battery cannot be
fully charged. Therefore you should always check whether the charger has been
switched to maintenance charge before you leave it turned on or unobserved for
any length of time. Caution: If the US 3300 Corvette (model 1051) does not switch
to maintenance charge mode after three days, manually switch it to pulse mainte-
nance mode. If the set has been switched to maintenance charge, then everything
is in order. Note: A battery that hasn’t changed to maintenance charge after three
days is most likely worn out and needs to be replaced.All other batteries can be
maintained for a very long time.
