• Stop the unit and disconnect the power source when not in use. Carry the unit with the motor stopped.
• Store out of the reach of children.
• Do not hang unit so that the switch trigger is depressed.
• 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. Always engage the lock-out lever before placing the trimmer on the wall-mounted charger. Following this rule will reduce the risk of electric shock, fire, or serious personal injury.
• Under abusive conditions, liquid may be ejected 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 dispose of the batteries in a fire. The cell may explode. Check with local codes for possible special disposal instructions.
• Do not open or mutilate the batteries. Released electrolyte is corrosive and may cause damage to the eyes or skin. It may be toxic if swallowed.
• Do not place battery tools or their batteries near fire or heat. This will reduce the risk of explosion and possibly injury.
• Batteries 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 crush, drop or damage 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.
• Under extreme usage or temperature conditions, battery leakage may occur. If liquid comes in contact with your skin, wash immediately with soap and water. If liquid gets into your eyes, flush them with clean water for at least 10 minutes, then seek immediate medical attention. Following this rule will reduce the risk of serious personal injury.
• Recharge only with the charger specified by the manu-facturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.
• Use appliances 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.
• Follow all charging instructions and do not charge the battery pack or appliance outside of the temperature range specified in the instructions. Charging improperly or at temperatures outside of the specified range may damage the battery and increase the risk of fire.

A – Button
B – Line

• Use the tip of the line to do the cutting; do not force string head into uncut grass.
• Wire and picket fences cause extra line wear, even breakage. Stone and brick walls, curbs, and wood may wear line rapidly.
• Avoid trees and shrubs. Tree bark, wood moldings, siding, and fence posts can easily be damaged by the line.

ADVANCING LINE

LINE CUT-OFF BLADE
See Figure 12.

• A – Screw
• B – Line cut-off blade

This trimmer is equipped with a line cut-off blade on the grass deflector. For best cutting, advance line until it is trimmed to length by the line cut-off blade. Advance line whenever you hear the engine running faster than normal, or when trimming efficiency diminishes. This will maintain best performance and keep line long enough to advance properly.
