Use only identical manufacturer’s replacement parts and accessories. Use of any other parts may create a hazard or cause product damage.

Always wear safety glasses with side shields marked to comply with ANSI Z87.1. Everyday glasses have only impact-resistant lenses. They are NOT safety glasses. Following this rule will reduce the risk of eye injury. Use a face mask if operating in dusty workspaces.
Avoid Dangerous Environment – Don’t expose power tools to damp conditions. Water entering a power tool will increase the risk of electric shock.
Don’t use it in the rain.

Keep all bystanders, children, and pets at least 50 ft. away.
Dress Properly – Do not wear loose clothing or jewellery. They can be caught in moving parts. The use of rubber gloves and substantial footwear is recommended when working outdoors. Wear a protective hair covering to contain long hair.
Use the right Appliance. Do not use an appliance for any job except that for which it is intended.

Avoid Unintentional Starting – Don’t carry the appliance with your finger on the switch. Be sure the switch is off when the battery is plugged in.
Don’t Force Appliance – It will do the job better and with less likelihood of a risk of injury at the rate for which it was designed.
Don’t overreach – Keep proper footing and balance at all times.

Stay alert – Watch what you are doing. Use common sense. Do not operate this unit when you are tired, ill or under the influence of alcohol, drugs or medication.
Always store idle power tools indoors – When not in use, power tools should be stored indoors in a dry and high or locked-up place, out of reach of children.
Maintain Appliance With Care – Replace string head if cracked, chipped, or damaged in any way. Be sure the string head is properly installed and securely fastened. Keep cutting edge sharp and clean for best performance and to reduce the risk of injury. Follow instructions for lubricating and changing accessories. Inspect appliance cord periodically, and if damaged, have it repaired by an authorized service facility. Inspect extension cords periodically and replace them if damaged. Keep handles dry, clean, and free from oil and grease. Failure to do so can cause serious injury.

Check damaged parts before using the appliance, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function. Check for alignment of moving parts, binding of moving parts, breakage of parts, damaged mountings, and any other condition that may affect its operation. A guard or other part that is damaged should be properly repaired or replaced by an authorized service centre unless indicated elsewhere in this manual.
Remove or disconnect the battery before servicing, cleaning or removing material from the gardening appliance.
Do not modify or attempt to repair the appliance or the battery pack (as applicable) except as indicated in the instructions for use and care. Use appliances only with speciﬁcally designated battery packs.

Use of any other battery packs may create a risk of injury and ﬁre. Use only with Greenworks GBA80250/BAB723/GBA80200 battery or other BAB series.
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 only with Greenworks GCH8040 charger or other CAB series.
When the 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 a fire.

Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts the eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.
Do not use a battery pack or appliance that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behaviour resulting in fire, explosion or risk of injury.
Do not expose a battery pack or appliance to fire or excessive temperature. Exposure to fire or temperature above 265 °F (130 °C) may cause an explosion.

Do not dispose of the batteries in a fire. The cells 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.
Exercise care in handling batteries in order not to short the battery with conducting materials such as rings, bracelets, and keys. The battery or conductor may overheat and cause burns.

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.
Have servicing performed by a qualified repair person using only identical replacement parts. This will ensure that the safety of the product is maintained.
Keep guards in place and working order.

Keep hands and feet away from the cutting area.
Disconnect the battery pack from the appliance before making any adjustments, changing accessories, or storing the appliance. Such preventive safety measures reduce the risk of starting the appliance accidentally.
