of the cable, that is, 16 gauge has more capacity than 18 gauge.
An undersized cord will cause a drop in line voltage resulting in loss
of power and overheating. The following table shows the correct
size to use depending on cord length and nameplate ampere
rating. If in doubt, use the next heavier gauge. The lower the gauge
number, the heavier the cord.

• Do not place any object on top of the charger or place the charger
on a soft surface that might block the ventilation slots and result in
excessive internal heat. Place the charger in a position away from
any heat source.
• Do not operate the charger with a damaged cord or plug.
• Do not operate the charger if it has received a sharp blow, been
dropped or otherwise damaged in any way.
• Do not disassemble the charger. Incorrect reassembly may result in
a risk of electric shock, electrocution or fire.
• Disconnect the charger from the outlet before attempting any
cleaning. This will reduce the risk of electric shock. Removing the
battery pack will not reduce this risk.

Not Recommended
• NEVER attempt to connect two chargers together.
• The charger is designed to operate on standard 120V household
electrical power. Do not attempt to use it on any other voltage.
Personal Precautions
• Consider having someone close enough by to come to your aid
when you work near a lead-acid battery.
• Wear complete eye protection and clothing protection. Avoid
touching eyes while working near battery.
• Have plenty of fresh water and soap nearby in case battery acid
contacts skin, clothing, or eyes.
• 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.

• If battery acid contacts skin or clothing, wash immediately 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.
• NEVER smoke or allow a spark or flame in vicinity of battery or
engine.
• 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.
Important Notes:
Several factors can affect a charger's ability to charge a vehicle's
battery, including, but not limited to, the size of the vehicle battery, the
temperature (hot or cold), whether the battery is damaged or defective,
and whether the D
