SAFETY INSTRUCTIONS

Read all safety warnings, instructions, illustrations , and specifications. Failure to follow all instructions listed below may result in electric shock, fire, and/or serious injury.

Work area safety
Keep work area clean and well-lit. Cluttered or dark areas invite accidents.
Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.

Electrical safety
Do not expose power tools to rain or wet
conditions. Water entering a power tool will increase the risk of electric shock.

Battery tool use and care
Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.
Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.
When battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws, or other small metal objects, that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.
Under abusive conditions, liquid may beejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.

Do not use a battery pack or tool that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behavior resulting in fire, explosion, or risk of injury.
Do not expose a battery pack or tool to fire or excessive temperature. Exposure to fire or temperature above 265 °F may cause explosion.
Follow all charging instructions and do not charge the battery pack or tool outside the temperature range specified in the instructions.  Charging improperly or at temperatures outside the specified range may damage the battery and increase the risk of fire.

Service
Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.
Never service damaged battery packs. Service of battery packs should only be performed by the manufacturer or authorized service providers.

SAFETY RULES FOR BATTERIES

Before using battery, read all instructions and cautionary markings on (1) battery charger, (2) battery pack, and (3) product using battery.

Risk of fire and burns. Do not recharge, disassemble, heat above 100 °C (212 °F), or incinerate. Keep battery out of reach of children and in original package until ready to use.

Battery tools do not have to be plugged into an electrical outlet; therefore, they are always in operating condition. Be aware of possible hazards when not using your battery tool or when changing accessories.

Do not place battery tools or their batteries near fire or heat. 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 crush, drop or damage the battery pack. Do not use a battery pack or charger that has been dropped or received a sharp blow. A  damaged battery is subject to explosion. Properly dispose of a dropped or damaged battery immediately.

Do not insert battery pack in charger if battery pack case is cracked. Using damaged battery pack may result in electric shock or fire.

Batteries vent hydrogen gas and can explode in the presence of a source of ignition such as a pilot light. To reduce the risk of serious personal injury, never use any cordless product in the presence of open flame. An exploded battery can propel debris and chemicals. If exposed, flush with water immediately.

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.

Do not store outside or in vehicles.
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.

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.

Do not let gasoline, oils, petroleum-based products, etc. come in contact with plastic parts. They contain chemicals that can damage,  weaken or destroy plastic.

Do not touch the uninsulated portion of output connector or uninsulated battery terminal. There is a risk of electric shock.

Replace  battery pack if a substantial drop in operating time per charge is observed. Battery pack may be nearing the end of its life.

BATTERY CARE

When batteries are not in tool or charger, keep them away from metal objects. For example, to protect terminals from shorting DO  NOT place batteries in a tool box or pocket with nails, screws, keys, etc. Fire or injury may result.
DO NOT PUT BATTERIES INTO FIRE OR EXPOSE TO HIGH HEAT. They may explode.

BATTERY DISPOSAL

Do not attempt to disassemble the battery or remove any component projecting from the battery terminals. Fire or injury may result. Prior to disposal, protect exposed terminals with heavy insulating tape to prevent shorting.

Lithium-Ion Batteries: If equipped with a lithium-ion battery, the battery must be collected, recycled, or disposed of in an environmentally sound manner.

The EPA certified RBRC Battery Recycling Seal on the lithium-ion (Li-ion) battery indicates Chervon North America is voluntarily participating in an industry program to collect and recycle these batteries at the end of their useful life when taken out of service in the  United States or Canada. The RBRC program provides a convenient alterative to placing used Li-ion batteries into the trash or the municipal waste stream, which may be illegal in your area. Please call 1-800-8-BATTERY for information on Li-ion battery recycling and disposal bans/ restrictions in your area, or return your batteries to a FLEX Service Center for recycling. Chervon North America’s involvement in this program is part of our commitment to preserving our environment and conserving our natural resources.

• 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.

NOTE: Use of chargers or battery packs not sold by FLEX will void the warranty.

OPERATING INSTRUCTIONS

To reduce the risk of fire, personal injury, and product damage due to a short circuit, never immerse your charger or battery pack in fluid or allow a fluid to flow inside them. Corrosive or conductive fluids, such as seawater, certain industrial chemicals, bleach or bleach-containing products, etc. can cause a short circuit.

Do not attempt to modify the battery pack or create accessories not recommended for use with this battery pack.   Any such alteration or modification is misuse and could result in a  hazardous condition leading to possibly serious personal injury.

POWER INDICATOR
This lithium-ion battery pack is equipped with power indicators on both sides of the battery pack that display the battery charge level.
Press the power-indicator button on the front of battery pack to display the four LEDs in the power indicator. The LEDs will remain lit for approximately 10 seconds. It is recommended that the battery pack be recharged to full charge before starting a big job or using it for long periods of time.
The power indicator can be used regardless whether the battery is attached or removed from tool.

Press the power-indicator button and the LEDs will light up to communicate the battery pack charge level:

OVER-VOLTAGE WARNING
If the battery pack is charged at a voltage above this threshold level, all four LEDs will rapidly flash green for approximately 10 seconds. Remove the battery pack from the charger or power tool.

LOW-CAPACITY WARNING
If one LED on the power indicator begins to flash, the battery pack charge is under 10% capacity and should be recharged. Unlike other types of battery packs, lithium-ion battery packs deliver fade-free power for their entire run time. The tool will not experience a slow,  gradual loss of power as it is used.

The power delivered to the tool will drop quickly when the battery pack is at the end of its run time and needs to be charged. When the battery pack is completely discharged or overvoltage, the power indicator will begin to flash all four LEDs. When this happens, remove the tool from the workpiece and charge the battery pack as needed.

OVER-TEMPERATURE WARNING
The battery circuitry also protects the battery pack from overheating. To protect the battery pack from damage and prolong its life, the battery pack circuitry will send a warning signal to the tool if the temperature becomes too high during use. The first and third LEDs on the power indicator will rapidly flash green to warn of the over-temperature condition.
This may happen in extremely high torque, binding, and stalling situations. The battery pack will begin normal operation after it has cooled down.
NOTICE: A significantly reduced run time after fully charging the battery pack indicates that the batteries are near the end of their usable life and must be replaced.

COLD WEATHER OPERATION
When the battery pack is very cold, the performance may be weakened. Put the battery pack on a tool and use the tool in a light application for a while to “warm-up” the battery pack or place the battery pack in room temperature until it has warmed. The battery pack will operate normally.

TO CHARGE THE BATTERY PACK (FIG. 2)

NOTICE: This lithium-ion battery pack is shipped partially charged. Before using it for the first time, fully charge the battery pack.
Always charge the battery pack with the correct charger.
Please refer to the charger manual for detailed charging instructions.
a. Connect the charger to a power supply.
b. Attach the battery pack to the charger by aligning the raised ribs of the battery pack with the slot in the charger. Slide the battery pack onto the charger.
c. When the charger indicates that the battery pack is fully charged, remove it from the charger.
NOTICE: If the battery pack cannot accept a charge, the contacts of the charger or battery pack may be contaminated. Clean the contacts of the charger or battery pack (e.g., by inserting and removing the battery several times or scrubbing with a cotton swab and alcohol), or replace the battery pack, as required.
