BATTERY & CHARGER INSTRUCTIONS

Despite all the safety precautions, caution must always be exercised when handling batteries. The following points must be obeyed at all times to ensure safe use. Safe use can only be guaranteed if undamaged cells are used. Incorrect handling of the battery pack  can cause cell damage.

• AVOID DANGEROUS ENVIRONMENTS – Do not charge the battery pack in rain, snow or in damp or wet locations. Do not use the battery pack or charger in the presence of explosive atmospheres (gaseous fumes, dust or flammable materials)  because sparks may be generated when inserting or removing the battery pack, which could lead to a fire.

• CHARGE IN A WELL-VENTILATED AREA – Do not block the charger vents. Keep them clear to allow for proper ventilation. Do not allow smoking or open flames near a charging battery pack. Vented gases may explode.
  NOTE: The safe temperature range for the battery charging is -4°F to 113°F. Do not charge the battery outside in freezing weather; charge it at room temperature.

• MAINTAIN CHARGER CORD – When unplugging the charger, pull the plug, not the cord, from the receptacle to reduce the risk of damage to the electrical plug and cord. Never carry the charger by its cord or yank it by the cord to disconnect it from the  eceptacle. Keep the cord away from heat, oil and sharp edges. Make sure the cord will not be stepped on, tripped over or subjected to damage or stress when the charger is in use. Do not use the charger with a damaged cord or plug. Replace a damaged charger immediately.

• DO NOT USE AN EXTENSION CORD UNLESS IT IS ABSOLUTELY NECESSARY – Using the wrong, damaged or improperly wired extension cord poses a risk of fire and electric shock. If an extension cord must be used, plug the charger into a  properly wired 16 gauge or larger extension cord with the female plug matching the male plug on the charger. Make sure that the extension cord is in good electrical condition.

• CHARGER IS RATED FOR 120 VOLT AC ONLY – The charger must be plugged into an appropriate receptacle.

• USE ONLY RECOMMENDED ATTACHMENTS – Use of an attachment not recommended or sold by WEN Products may result in risk of fire, electric shock or personal injury.

• UNPLUG CHARGER WHEN NOT IN USE – Make sure to remove battery packs from unplugged chargers.
  WARNING! To reduce the risk of electric shock, always unplug the charger before performing any cleaning or maintenance. Do not allow water to flow into the charger. Use a Ground Fault Circuit Interrupter (GFCI) to reduce shock hazards.

• DO NOT BURN OR INCINERATE BATTERY PACKS – Battery packs may explode, causing personal injury or damage. Toxic fumes and materials are created when battery packs are burned.

• DO NOT CRUSH, DROP OR DAMAGE BATTERY PACKS – Do not use the battery pack or charger if they have sustained a sharp blow, been dropped, run over or have been damaged in any way (i.e. pierced with a nail, hit with a hammer, stepped on,  tc.).

• DO NOT DISASSEMBLE – Incorrect reassembly may pose a serious risk of electric shock, fire or exposure to toxic battery chemicals. If the battery or charger are damaged, call WEN customer service at 1-847-429-9263 for assistance.

• BATTERY CHEMICALS CAUSE SERIOUS BURNS – Never let a damaged battery pack contact the skin, eyes or mouth. If a damaged battery pack leaks battery chemicals, use rubber or neoprene gloves to safely dispose of it.
  If skin is exposed to battery fluids, wash the affected area with soap and water and rinse with vinegar. If eyes are exposed to battery chemicals, immediately flush with water for 20 minutes and seek medical attention. Remove and dispose of contaminated  clothing.

• STORE YOUR BATTERY PACK AND CHARGER IN A COOL, DRY PLACE – Do not store the battery pack or charger where temperatures may exceed 104 °F, such as in direct sunlight or inside a vehicle or metal building during the summer.

• DO NOT SHORT CIRCUIT – A battery pack will short circuit if a metal object makes a connection between the positive and negative contacts on the battery pack. Do not place a battery pack near anything that may cause a short circuit, such as paper  clips, coins, keys, screws, nails and other metallic objects. A short-circuited battery pack poses a risk of fire and severe personal injury.

1. The battery pack has to be charged completely before you use the tool for the first time.
2. For optimum battery performance, avoid low discharge cycles by charging battery pack frequently.
3. Lithium-ion batteries are subject to a natural aging process. The battery pack must be replaced at the latest when its capacity falls to just 80% of its capacity when new. Weakened cells in an aged battery pack are no longer capable of meeting the high power  equirements needed for the proper operation of your tool, and therefore pose a safety risk.
4. Do not throw battery packs into an open fire as this poses a risk of explosion. Do not ignite the battery pack or expose it to fire.
5. Do not exhaustively discharge batteries. Exhaustive discharge will damage the battery cells. The most common cause of exhaustive discharge is lengthy storage or non-use of partially discharged batteries. Stop working as soon as the performance of the  battery falls noticeably or the electronic protection system triggers. Place the battery pack in storage only after it has been fully charged.
6. Protect batteries and the tool from overloads. Overloads will quickly result in overheating and cell damage inside the battery housing even if this overheating is not apparent externally.
7. Avoid damage and shocks. Immediately replace batteries that have been dropped from a height of more than one meter or those that have been exposed to violent shocks, even if the housing of the battery pack appears to be undamaged. The battery cells  inside the battery may have suffered serious damage. In such instances, please read the waste disposal information for proper battery disposal.
8. If the battery pack suffers overloading and overheating, the integrated protective cutoff will switch off the equipment for safety reasons.
9. Use only original battery packs. The use of other batteries poses a fire risk and may result in injuries or an explosion.

ABOUT THE CHARGER
Protect the battery charger and its cord from damage. Keep the charger and its cord away from heat, oil and sharp edges. Electrical plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with grounded appliances.  Unmodified plugs and matching outlets will reduce the risk of electric shock.
Keep the battery charger, battery pack(s) and the cordless tool out of the reach of children. Do not use the supplied battery charger to charge other cordless tools. During periods of heavy use, the battery pack will become warm. Allow the battery pack to cool to  room temperature before inserting it into the charger to recharge.
Do not overcharge batteries. Do not exceed the maximum charging times. These charging times only apply to discharged batteries. Frequent insertion of a charged or partially charged battery pack will result in overcharging and cell damage. Do not leave battery  in the charger for days on end. Never use or charge a battery if you suspect that it has been more than 12 months since the last time they were charged. There is a high probability that the battery pack has already suffered dangerous damage (exhaustive  discharge). Do not use battery that have been exposed to heat during the charging process, as the battery cells may have suffered dangerous damage. Do not use battery that have suffered curvature or deformation during the charging process or those that exhibit  other atypical symptoms (gassing, hissing, cracking, etc.)

WARNING! Waste electrical products should not be disposed of with household waste. Please recycle where facilities exist. Check with local authority or retailer for recycling advice.

CHARGING THE BATTERY

1. Plug the charger into a 120V, 60Hz AC power source.
2. Slide the battery all the way into the charger stand until it clicks.
3. Refer to the instructions included with your charger for the meanings of the status LEDs on the charger.

NOTE: It is normal for batteries to become warm while charging. If battery is hot after continuous use in the tool, allow it to cool down to room temperature before charging. This will extend the life of your batteries.
WARNING! Always disconnect the battery pack from the tool before any assembly, adjustments or changing accessories.
