16. Battery Jump-start Precautions
Warning – Follow these steps when jumpstarting a vehicle. A spark near battery may cause a battery
explosion to reduce risk of a spark near battery or injury, follow precautions below.
a. Always connect the external connection cable clamps to the car battery terminals prior connecting to the
Powerstation. Never touch the battery clamps together, this can cause dangerous sparks, power arcing
and/ or explosion.
b. Jump-start procedures should only be performed in a safe, dry, well-ventilated area.
c. When operating the unit near the vehicle’s battery and engine, place it on a flat, stable surface and
ensure that all clamps, cords, clothing, and body parts are kept clear of any moving vehicle components.
d. Check the polarity of the battery posts. POSITIVE (POS,P, +) battery posts usually have a larger diameter
than NEGATIVE (NEG, N, -) posts.
e. Determine which post of battery is grounded (connected) to the chassis. If the negative post is grounded
to chassis, (as in most vehicles), see (f). If the positive post is grounded to chassis, see (g).
f. For negative-grounded vehicles, connect the POSITIVE (RED) clip from jump-start cable to the
POSITIVE (POS, P, +) ungrounded post of the battery. Connect the NEGATIVE (BLACK) clip to the
vehicle chassis or engine block away from the battery. Do not connect the clip to carburetor, fuel lines, or
sheet-metal body parts. Connect to a heavy gauge metal part of the frame or engine block.
g. For positive-grounded vehicle, connect NEGATIVE (BLACK) clip from jump-start cable to NEGATIVE
(NEG, N, -) ungrounded post of battery. Connect the POSITIVE (RED) clip to vehicle chassis or engine
block away from the battery. Do not connect the clip to carburetor, fuel lines, or sheet- metal body parts.
Connect to a heavy gauge metal part of the frame or engine block.
h. When disconnecting the cables, (1) disconnect the External Battery Connection Terminal from the
Powerstation, (2) then the black negative clamps (-) and then the red positive clamp (+), in that order.
i. Store in a cool, dry place and out of reach of children.
j. Final jump-start Cautions
i.
Vehicles that have on-board computerized systems may be damaged if vehicle battery is jump-started.
Before jump-starting, read the vehicle's owner’s manual to confirm that external starting assistance is
advised.
ii.
Excessive engine cranking can damage a vehicle's starter motor. If the engine fails to start after the
recommended number of attempts, discontinue jump-start procedures and look for other problems that
may need to be corrected.
