the instructions, may cause harmful interference to radio communications. However, there
is no guarantee that interference will not occur in a particular installation. If equipment does
cause harmful interference to radio or television reception, which can be determined by turning
the equipment off and on, the user is encouraged to try to correct the interference by one or
more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
• Consult the dealer or an experienced radio/TV technician for help.
Changes or modifications not approved by the party responsible for compliance could void
user's authority to operate the equipment.

GENERAL SAFETY WARNINGS AND INSTRUCTIONS FOR ALL BATTERY CHARGERS
READ ALL INsTRUCTIONs
WARNING: Read all instructions before operating product. Failure to follow all instructions listed
below may result in electric shock, fire and/or serious injury.
• AVOID DANGEROUS ENVIRONMENTS: Don't use charger in damp or wet locations. Don't use charger in
the rain.
• KEEP CHILDREN AWAY. All visitors should be kept at a distance from work area.
• STORE CHARGER INDOORS. When not in use, charger should be stored indoors in dry, and high or
locked-up place — away from reach of children.
• GROUND FAULT CIRCUIT INTERRUPTER (GFCI) protection should be provided on the circuits or
outlets to be used. Receptacles are available having built in GFCI protection and may be used for this
measure of safety.
• DO NOT OPERATE near flammable liquids or in gaseous or explosive atmospheres. Sparks might
ignite fumes.
DANGER – Never alter AC cord or plug provided – if it will not fit outlet, have proper outlet
installed by a qualified electrician. Improper connection can result in a risk of an electric shock.
• OUTDOOR USE EXTENSION CORDS. When charger is used outdoors, use only extension cords
intended for use outdoors and so marked.

• EXTENSION CORDS. Make sure your extension cord is in good condition. When using an extension
cord, be sure to use one heavy enough to carry the current your product will draw. 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 gage. The smaller the gage number, the heavier the cord.

WARNING: BURST HAZARD: Do not use the unit for charging dry-cell batteries that are commonly
used with home appliances. These batteries may burst and cause injury to persons and damage property.
Use the unit for charging/boosting a LEAD-ACID battery only.
WARNING: SHOCK HAZARD:
• If an extension cord is used, make sure that:
a) the pins of extension cord are the same number, size and shape as those in the charger,
b) the extension cord is properly wired and in good electrical condition,
c) the wire size is large enough for the AC rating of the charger as indicated in the table in the
previous section.
• Do not operate unit with damaged cord or plug; or if the unit has received a sharp blow,
been dropped, or otherwise damaged in any way. Do not disassemble the unit; return it to the
manufacturer when service or repair is required. Opening the unit may result in a risk of electric
shock or fire, and will void warranty.
• Use of an attachment not supplied, recommended or sold by manufacturer specifically for use with
this unit may result in a risk of electrical shock and injury to persons.
• NEVER submerge this unit in water; do not expose it to rain, snow or use when wet.
• To reduce risk of electric shock, disconnect the unit from any power source before attempting
maintenance or cleaning. Turning off controls without disconnecting will not reduce this risk.
WARNING: RISK OF EXPLOSIVE GASES
• Working in the vicinity of a lead acid battery is dangerous. Batteries generate explosive gases during
normal battery operation. For this reason, it is of the utmost importance that each time before using
the charger you read this manual and follow instructions exactly.
• To reduce the risk of battery explosion, follow these instructions and those published by the battery
manufacturer and manufacturer of any equipment you intend to use in the vicinity of the battery.
Review cautionary markings on these products and on the engine.
• This equipment employs parts (switches, relays, etc.) that produce arcs or sparks. Therefore, if used
in a garage or enclosed area, the unit MUST be placed not less than 18 inches above the floor.
• THIS UNIT IS NOT FOR USE BY CHILDREN AND SHOULD ONLY BE OPERATED BY ADULTS.
CAUTION: TO REDUCE THE RISK OF INJURY OR PROPERTY DAMAGE:
• Pull cord by plug rather than cord when disconnecting the 120V AC Charging Adapter from the unit.
