3. PREPARING TO USE THE UNIT WITH A BATTERY
WARNING: RISK OF CONTACT WITH
BATTERY ACID. BATTERY ACID IS A
HIGHLY CORROSIVE SULFURIC ACID.
3.1 If necessary to remove the battery from
the vehicle, always remove the grounded
terminal from battery rst. Make sure all
accessories in the vehicle are off, so as
not to cause an arc.
3.2 Be sure area around battery is well
ventilated while using the unit.
3.3 Clean battery terminals. Be careful to
keep corrosion from coming in contact
with eyes.
3.4 Add distilled water in each cell until
battery acid reaches level specied by
battery manufacturer. Do not overll. For a
battery without removable cell caps, such
as valve regulated lead acid batteries,
carefully follow manufacturer’s recharging
instructions.
3.5 Study all battery manufacturer’s specic
precautions while using the unit with
a battery.
3.6 Determine the voltage of the battery by
referring to the car owner’s manual and
make sure that the battery is a 12V rated
battery. The unit is designed for 12V
batteries only.
3.7 Make sure that the unit's cable clips make
tight connections.
4. UNIT LOCATION
WARNING: RISK OF EXPLOSION
AND CONTACT WITH BATTERY ACID.
4.1 Locate the unit as far away from battery
as DC cables permit.
4.2 Never place the unit directly above the
battery; gases from battery will corrode
and damage the unit.
4.3 Never allow battery acid to drip on the unit
when reading electrolyte specic gravity
or lling battery.
4.4 Do not operate the unit in a closed-in area
or restrict ventilation in any way.
4.5 Do not set a battery on top of the unit.
5. DC CONNECTION PRECAUTIONS
5.1 Connect and disconnect DC output clips
only after setting any switches to “off”
position and removing AC cord from
electric outlet. Never allow the clips of the
unit to touch each other.
5.2 Attach clips to battery and chassis, as
indicated in sections 6 and 7.
6. FOLLOW THESE STEPS WHEN BATTERY IS INSTALLED IN VEHICLE
WARNING: A SPARK NEAR THE
BATTERY MAY CAUSE A BATTERY
EXPLOSION. TO REDUCE THE RISK OF
A SPARK NEAR THE BATTERY:
6.1 Position AC and DC cords to reduce risk
of damage by hood, door, or moving
engine part.
6.2 Stay clear of fan blades, belts, pulleys, and
other parts that can cause injury to persons.
6.3 Check polarity of battery posts. POSITIVE
(POS, P, +) battery post usually has larger
diameter than NEGATIVE (NEG, N,–) post.
6.4 Determine which post of battery is
grounded (connected) to the chassis. If
negative post is grounded to chassis (as
in most vehicles), see (6.5). If positive
post is grounded to the chassis, see (6.6).
6.5 For negative-grounded vehicle, connect
POSITIVE (RED) clip from the unit 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 gauge metal
part of the frame or engine block.
6.6 For positive-grounded vehicle, connect
NEGATIVE (BLACK) clip from the unit
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 gauge metal
part of the frame or engine block.
6.7 Connect the unit's AC supply cord to
electrical outlet and press the START/
STOP button to turn the output on.
6.8 When disconnecting the unit, press the
START/STOP button to turn the output off,
disconnect the AC cord, remove the clip
from the vehicle chassis and then remove
the clip from the battery terminal.
