2. PERSONAL PRECAUTIONS
WARNING! RISK OF EXPLOSIVE GASES. A SPARK NEAR THE
BATTERY MAY CAUSE A BATTERY EXPLOSION. TO REDUCE THE
RISK OF A SPARK NEAR THE BATTERY:
2.1 NEVER smoke or allow a spark or ame in the vicinity of a battery or engine.
2.2 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 to
metal, causing a severe burn.
2.3 Be extra cautious, to reduce the risk of dropping a metal tool onto the
battery. It might spark or short-circuit the battery or other electrical
part that may cause an explosion.
2.4 Do not permit the internal battery of the unit to freeze. Never charge a
frozen battery.

the battery and chassis as indicated below. Never allow the output
clamps to touch each other.
4.2 Position the DC cables to reduce the risk of damage by the hood,
door and moving or hot engine parts. NOTE: If it is necessary to close
the hood during the jump starting process, ensure that the hood does
not touch the metal part of the battery clips or cut the insulation of the
cables.
4.3 Stay clear of fan blades, belts, pulleys and other parts that can cause injury.
4.4 Check the polarity of the battery posts. The POSITIVE (POS, P, +)
battery post usually has a larger diameter than the NEGATIVE (NEG,
N, -) post.
4.5 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 step 4.6. If the positive post is grounded to the chassis,
see step 4.7.
4.6 For a negative-grounded vehicle, connect the POSITIVE (RED) clamp
from the jump starter to the POSITIVE (POS, P, +) ungrounded post
of the battery. Connect the NEGATIVE (BLACK) 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. Connect
to a heavy gauge metal part of the frame or engine block.
4.7 For a positive-grounded vehicle, connect the NEGATIVE (BLACK)
clamp from the jump starter to the NEGATIVE (NEG, N, -) ungrounded
post of the battery. Connect 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. Connect to
a heavy gauge metal part of the frame or engine block.
4.8 When nished using the jump starter, remove the clamp from the
vehicle chassis and then remove the clamp from the battery terminal.
