IMPORTANT SAFETY
INSTRUCTIONS
CALIFORNIA PROPOSITION 65
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
MUS 4.3 TEST&CHARGE (1077).
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 injury to
persons.
4. To reduce risk of damage to electric plug and cord, pull
by the plug rather than cord when disconnecting charger.
5. An extension cord should not be used unless absolutely
necessary. Use of improper extension cord could result
in a risk of fire and electric shock. If an extension cord
must be used, make sure that: a) Pins on plug of exten-
sion cord are the same number, size and shape as those

enough for AC ampere rating of charger as specified
in “RECOMMENDED MINIMUM AWG SIZE FOR AC
EXTENSION CORDS”.
6. Do not operate charger with damaged cord or plug –
return the charger to the retailer.
7. Do not operate charger if it has received a sharp blow,
been dropped or otherwise damaged in any way; take it
to the retailer.
8. Do not disassemble charger; take it to the retailer 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 attempting any maintenance or cleaning.
10. 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 OUTMOST
IMPORTANCE THAT YOU
FOLLOW THE INSTRUCTIONS
EACH TIME YOU USE THE
CHARGER.
b) To reduce risk of battery explosion, follow these instruc-
tions and those published 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. PERSONAL PRECAUTIONS
a) Consider having someone close enough by to come to
your aid when you work near a lead-acid battery.
b) Have plenty of fresh water and soap nearby in case bat-
tery 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 immedi-
ately 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 bat-
tery 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. 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 batter-
ies 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 bat-
tery 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 lead acid batteries, carefully follow manufac-
turer’s recharging instruction.
e) Study all battery manufacturer’s specific precautions
while charging and recommended rates of charge.
f) Determine voltage of battery by referring to car owner’s
manual and make sure it matches output rating of battery
charger.
13. 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 read-
ing electrolyte 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 top of charger.

14. 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 and chassis as indicated in 15(e),
15(f), 16(b) through 16(d).
15. 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 the chassis
(as in most vehicles) see (e). If positive post is grounded to
the chassis, see (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 carbure-
tor, 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, discon-
nect AC cord, remove clip from vehicle chassis, and then
remove clip from battery terminal.
h) See operating instructions for length of charge
information.
16. FOLLOW THESE STEPS WHEN
BATTERY IS OUTSIDE VEHICLE.
A SPARK NEAR BATTERY MAY

CAUSE BATTERY EXPLOSION.
TO REDUCE RISK OF
A SPARK NEAR BATTERY:
a) Check polarity of battery terminals. POSITIVE (POS,
P, +) battery post usually has a larger diameter than
NEGATIVE (NEG, N, -) post.
b) Connect POSITIVE (RED) charger clip to POSITIVE (POS,
P, +) post of battery.
c) Position yourself and free end of cable as far away from
battery as possible – then connect NEGATIVE (BLACK)
charger clip to NEGATIVE (NEG, N, -) post of battery.
d) Do not face battery when making the final connection.
e) When disconnecting charger, always do so in reverse
sequence of connecting procedure and break first con-
nection while as far away from battery as practical.
f) A marine (boat) battery must be removed and charged
on shore. To charge it on board requires equipment spe-
cially designed for marine use.
IMPORTANT SAFETY
INFORMATION!
• Charge no other batteries than specified in TECHNICAL
INFORMATION.
• Check the charger cables prior to use. Ensure that no
cracks have occurred in the cables or in the bend protec-
tion. A charger with damaged cables must be returned to
the retailer.
• Ensure that the cabling does not jam or comes into contact
with hot surfaces or sharp edges.
• Never charge a damaged battery.
• Never place the charger on top of the battery when
charging.
• Avoid covering the charger.
• All batteries fail sooner or later. A battery that fails dur-
ing charging is normally taken care of by the chargers
advanced control, but some rare errors in the battery could
still exist. Don’t leave any battery during charging unat-
tended for a longer period of time.
• If power consumers like fitted alarms and navigation com-
puters are connected to the battery, the charging process
takes longer and may drain the battery.
• Always check that the charger has switched to STEP 7
before leaving the charger unattended and connected for
long periods. If the charger has not switched to STEP 7
within 50 hours, this is an indication of an error. Disconnect
the charger.
• Batteries consume water during use and charging. For bat-
teries where water can be added, the water level should
be checked regularly. If the water level is low add distilled
water.
