• Always have protective eyewear when using this product: contact with battery acid may cause blindness and/or
severe burns. Be aware of first aid procedures in case of accidental contact with battery acid.
• Have plenty of fresh water and soap nearby in case battery acid contacts skin.
• If battery acid contacts skin or clothing, wash immediately with soap and water for at least 10 minutes and get
medical attention immediately.
• Never smoke or allow a spark or flame in vicinity of vehicle battery, engine or power station
• 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, or similar metal
object, to skin, causing a severe burn.
• Do not wear vinyl clothing when jump-starting a vehicle when jump-starting a vehicle, friction can cause
dangerous static-electrical sparks.
• Jump-start procedures should only be performed in a safe, dry, well-ventilated area.
• Always store battery clamps when not in use. Never touch battery clamps together. This can cause dangerous
sparks, power arcing and/or explosion.
• When using this unit close to the vehicle's battery and engine, stand the unit on a flat, stable surface, and be sure
to keep all clamps, cords, clothing and body parts away from moving vehicle parts.
• Never allow RED and BLACK clamps to touch each other or another common metal conductor — this could
cause damage to the unit and/or create a sparking/explosion hazard.
a) For negative-grounded systems, connect the POSITIVE (RED) clamp to the POSITIVE ungrounded battery post
and 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.
b) For positive-grounded systems, connect the NEGATIVE (BLACK) clamp to the NEGATIVE ungrounded battery
post and 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.
• If the connections to the battery's POSITIVE and NEGATIVE terminals are incorrect, the Reverse Polarity Indicator
will light (red) and the unit will sound a beep. Disconnect clamps and reconnect to battery with correct polarity.
• Always disconnect the NEGATIVE (BLACK) jumper cable first, followed by the POSITIVE (RED) jumper cable,
except for positive grounded systems.
• Do not expose battery to fire or intense heat since it may explode. Before disposing of the battery, protect
exposed terminals with heavy-duty electrical tape to prevent shorting (shorting can result in injury or fire).
