IMPORTANT SAFETY INSTRUCTIONS

SAVE THESE INSTRUCTIONS
This manual contains important safety and operating instructions for battery charger Model FX0421. Do not substitute any other charger. Before using battery charger, read all instructions and cautionary markings on

1. battery charger,
2. battery pack, and
3. product using battery.

CAUTION To reduce risk of injury, charge only Li-Ion type rechargeable batteries. Other types of batteries may burst causing personal injury and damage. Charge only FLEX rechargeable batteries listed in the manual. Other types of batteries may burst causing personal injury and damage. Charge battery pack within the required temperature range. Store charger and battery pack in locations where temperature is within the recommended storage temperature range. This is important to prevent serious damage to the battery cells. Do not recharge battery in damp or wet environment. Do not expose charger to rain or snow. Water entering battery charger may result in electric shock or fire.
Battery leakage may occur under extreme usage or temperature conditions. Avoid contact with skin and eyes. The battery liquid is caustic and could cause chemical burns to tissues. If liquid comes in contact with skin, wash quickly with soap and water. If the liquid contacts your eyes, flush them with water for a minimum of 10 minutes and seek medical attention. Place charger on flat nonflammable surfaces and away from flammable materials when recharging battery pack. Carpeting and other heat insulating surfaces block proper air circulation which may cause overheating of the charger and battery pack. If smoke or melting of the charger or battery pack is observed, unplug the charger immediately and do not use the battery pack or charger. Contact customer service immediately. Keep the cord and charger from heat to prevent damage to housing or internal parts.Do not allow gasoline, oils, petroleum- based products, etc. to come in contact with plastic parts. These materials contain chemicals that can damage, weaken, or destroy plastic. Make sure cord is located so that it will not be stepped on, tripped over, or otherwise subjected to damage or stress. Damaged plug and cord may result in electric shock or fire. Disconnect the charger by pulling the plug rather than the cord. Do not operate charger with damaged cord or plug; have them replaced immediately. Damaged plug or cord may result in electric shock or fire. Do not insert battery pack in charger if battery pack case is cracked. Using damaged battery pack may result in electric shock or fire. Do not disassemble charger or operate the charger if it has received a sharp blow, been dropped or otherwise damaged in anyway. Incorrect reassembly or damage may result in electric shock or fire. Before each use, check the battery charger, cable and plug. If damage is detected, do not use the battery charger. Never open the battery charger yourself, take it to a FLEX Factory Service Center, or qualified serviceman only using original spare parts. Incorrect reassembly may result in electric shock or fire. Do not touch the uninsulated portion of output connector or uninsulated battery terminal. There is a risk of electric shock. Do not use attachment not recommended or sold by FLEX. Using attachments not recommended may result in electric shock or fire. Do not store battery pack in charger. Battery pack stored in charger over a long period of time could lead to battery pack damage and fire. Unplug charger from outlet before storage, attempting any maintenance or cleaning. Such preventive safety measures reduce the risk of electric shock or fire. Keep the battery charger clean by blowing compressed air on charger vents and wiping the charger housing with a damp cloth. Contamination may result in electric shock or fire.

EXTENSION CORDS
SED UNLESS ABSOLUTELY NECESSARY. Use of improper extension cord could result in risk of fire and electrical shock. If an extension make sure

•  The extension cord is properly wired and in good electrical condition.
•  The wire size is large enough for AC ampere rating of charger as specified below:

FCC CAUTION

1. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
2.  This device may not cause harmful interference.
3.  This device must accept any interference received, including interference that may cause undesired operation.
4. Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this 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 the 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.
• Some dust created by power sanding, sawing, grinding, drilling and other construction activities contains chemicals known to the State of California to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:
  •  Lead from lead-based paints.
  •  Crystalline silica from bricks, cement, and other masonry products.
  •  Arsenic and chromium from chemically-treated lumber.
• Your risk from these exposures varies, depending upon how often you do this type of work. To reduce your exposure to these chemicals:
  •  Work in a well-ventilated area.
  •  Work with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.
  •  Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling, and other construction activities. Wear protective clothing and wash exposed areas with soap and water. Allowing dust to get into your mouth or eyes or to lie on the skin may promote absorption of harmful chemicals.

CHARGING A HOT OR COLD BATTERY PACK
A steady red LED indicates that the battery is over or under the optimal temperature. Remove the battery pack from the charger. If the battery is too hot, cool the battery under air flow. If the battery is too cold, place it indoors until it reaches room temperature.
CHARGER ERROR
If the charger self-inspection fails to react when the charger is plugged in, the causes include no power to the charger, bad contacts, or a charger error. Check to see if the charger self-inspection can be activated when the charger is plugged in again or plugged into a different outlet. If  it still fails, have the charger serviced by an Authorized FLEX Service Station.

BATTERY PACK ERROR
If the charger detects a problem, the red/green LED will begin flashing red. Remove and re-insert the battery pack in the charger. If the red/green LED still flashes red, try charging a different battery pack.

•  If a different battery pack charges normally, have the first malfunctioning battery pack serviced by an Authorized FLEX Service Station.
•  If a different battery pack also indicates an error, the charger may be malfunctioning. Have the charger serviced by an Authorized FLEX Service Station.
