and sharp edges.
• DON'T OVERREACH. Keep proper footing and balance at all times.
• DISCONNECT APPLIANCES. Disconnect the appliance from the power supply when not in use, before servicing,
and when changing accessories such as blades and the like.
• AVOID UNINTENTIONAL STARTING. Don't carry plugged-in appliance with finger on switch. Be sure switch is off when
• 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.
• USE OF ACCESSORIES AND ATTACHMENTS. The use of any accessory or attachment not recommended for use
with this appliance could be hazardous. Note: Refer to the accessory section of this manual for further details.
• STAY ALERT. Watch what you are doing. Use common sense. Do not operate tool when you are tired.
• CHECK DAMAGED PARTS. Before further use of the tool, a guard or other part that is damaged should be carefully
checked to determine that it will operate properly and perform its intended function. Check for alignment of
moving parts, binding of moving parts, breakage of parts, mounting, and any other conditions that may affect its
operation. A guard or other part that is damaged should be properly repaired or replaced by an authorized service
center unless otherwise indicated elsewhere in this instruction manual. Have defective switches replaced by
authorized service center. Do not use tool if switch does not turn it on and off.
• DO NOT OPERATE portable electric tools near flammable liquids or in gaseous or explosive atmospheres. Motors
in these tools normally spark, and the sparks might ignite fumes.
• OUTDOOR USE EXTENSION CORDS. When tool is used outdoors, use only extension cords intended for use outdoors and
• 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 gauge. The smaller the gauge number, the heavier the cord.
Minimum Gauge for Cord Sets
Total Length of Cord in Feet
American Wire Gauge
WARNING: This product or its power cord contains lead, a chemical known to the State of California to cause
cancer and birth defect or other reproductive harm. Wash hands after handling.
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. It is not intended to supply power to a low-voltage electrical system other
than in a starter-motor application.
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 on page 1.
• 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; take it to a qualified service technician when
service or repair is required. Incorrect reassembly may result in a risk of electric shock or fire, and will void
• 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.
• Do not insert foreign objects into the USB outlet.
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 jump-starter
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.
• NEVER ATTEMPT TO JUMP-START OR CHARGE A FROZEN BATTERY.
• To recharge this unit, use only the supplied AC Charging Adapter.
• 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 suitable.
• When working with lead acid batteries, always make sure immediate assistance is available in case of accident
• 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.
