Important safety instructions for battery PACKS

For safe operation, read this manual and manuals originally supplied with tools before using the charger. The battery pack is not fully charged out of the carton. Before using the battery pack and charger, read the safety instructions below. Then follow the charging procedures outlined.

Read all Instructions

  • Do not incinerate the battery pack even if it is severely damaged or completely worn out. The battery pack can explode in a fire. Toxic fumes and materials are created when battery packs are burned.
  • Do not charge or use a battery in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Inserting or removing the battery from the charger may ignite dust or fumes.
  • If battery contents come into contact with the skin, immediately wash the area with mild soap and water. If battery liquid gets into the eye, rinse water over the open eye for 15 minutes or until irritation ceases. If medical attention is needed, the battery electrolyte for Li-ion batteries is composed of a mixture of liquid organic carbonates and lithium salts.
  • Contents of opened battery cells may cause respiratory irritation. Provide fresh air. If symptoms persist, seek medical attention.

Never attempt to open the battery pack for any reason. If the battery pack case is cracked or damaged, do not insert it into the charger. Do not crush, drop or damage the battery pack. Do not use a battery pack or charger that has received a sharp blow, been dropped, run over, or damaged in any way (i.e., pierced with a nail, hit with a hammer, stepped on). Damaged battery packs should be returned to a service center for recycling.

Storage Recommendations

The best storage place is one that is cool and dries away from direct sunlight and excess heat or cold. 2. Long storage will not harm the battery pack or charger.

Charger Diagnostics

This charger is designed to detect certain problems that can arise with the battery packs or the power source. Problems are indicated by one LED flashing in different patterns.

Bad battery
The charger can detect a weak or damaged battery. The red LED flashes in the pattern indicated on the label. If you see this bad battery blink pattern, do not continue to charge the battery. Return it to a service center or a collection site for recycling.

Hot/Cold pack delay

When the charger detects a battery that is excessively hot or excessively cold, it automatically starts a Hot/Cold Pack Delay, suspending charging until the battery has normalized. After this happens, the charger automatically switches to the Pack Charging mode. This feature ensures maximum battery life. The red LED flashes in the pattern indicated on the label when the hot/cold pack delay is detected.

Important Charging Notes

  1. The longest life and best performance can be obtained if the battery pack is charged when the air temperature is between 60°F and 80°F (16°- 27°C). DO NOT charge the battery pack in an air temperature below +40°F (+4.5°C), or above +105°F (+40.5°C). This is important and will prevent serious damage to the battery pack.
  2. The charger and battery pack may become warm to the touch while charging. This is a normal condition and does not indicate a problem. To facilitate the cooling of the battery pack after use, avoid placing the charger or battery pack in a warm environment such as in a metal shed, or an uninsulated trailer.
  3. The battery pack should be recharged when it fails to produce sufficient power on jobs that were easily done previously. DO NOT CONTINUE to use under these conditions. Follow the charging procedure. You may also charge a partially used pack whenever you desire with no adverse effect on the battery pack.
  4. Foreign materials of a conductive nature such as, but not limited to, steel wool, aluminum foil, or any buildup of metallic particles should be kept away from charger cavities. Always unplug the charger from the power supply when there is no battery pack in the cavity. Unplug the charger before attempting to clean it.
  5. Do not freeze or immerse the charger in water or any other liquid.


WARNING: To avoid serious injury, remove the battery from the tool before performing any maintenance.

  1. Keep the air intake slots clean to avoid overheating.
  2. Your trimmer line can dry out over time. To keep your line in top condition, store spare pre-wound spools or bulk line in a plastic,
    sealable bag with a tablespoon of water.
  3. Plastic parts may be cleaned by using a mild soap and a damp rag.
  4. The line cutter on the edge of the guard can dull over time. It is recommended you periodically touch-up the sharpness of the
    blade with a file.

IMPORTANT: To assure product SAFETY and RELIABILITY, repairs, maintenance and adjustment should be performed by
authorized service centers or other qualified service organizations, always using identical replacement parts.
