-
Do not Overreach – Keep proper footing and balance at all times.
-
Stay Alert – Watch what you are doing. Use common sense. Do not operate appliance when you are tired.
-
Store Idle Appliances Indoors – When not in use, appliances should be stored indoors in dry, and high or locked-up place out of reach of children.
-
Maintain Appliance With Care – Keep cutting edge sharp and clean for best performance and to reduce the risk of injury. Follow instructions for lubricating and changing accessories. Keep handles dry, clean, and free from oil and grease.
-
Check Damaged Parts – Before further use of 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, mounting, 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 center unless indicated elsewhere in this manual.
-
Keep hands away from blades.
-
Do not use or charge appliance in rain, or in wet locations.
-
Do not use battery-operated appliance in rain.
-
Remove or disconnect battery before servicing, cleaning or removing material from the appliance. Such preventive safety measures reduce the risk of starting the appliance accidentally.
-
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.
-
Use safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes, hard hat, or hearing protection must be used for appropriate conditions.
-
Be aware that this appliance is always in an operating condition, because it does not have to be plugged into an electrical outlet.
-
Do not operate appliances in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Appliances create sparks which may ignite the dust or fumes.
-
A battery operated appliance with integral batteries or a separate battery pack must be recharged only with the specified charger for the battery. A charger that may be suitable for one type of battery may create a risk of fire when used with another battery.
-
Use battery operated appliance only with specifically designated battery pack. Use of any other batteries may create a risk of fire.
-
Remove adjusting keys or wrenches before turning the appliance on. A wrench or a key that is left attached to a rotating part of the appliance may result in personal injury.
-
Do not use appliance if switch does not turn it on or off. An appliance that cannot be controlled with the switch is dangerous and must be repaired.
-
Use only accessories that are recommended by the manufacturer for your model. Accessories that may be suitable for one appliance may create a risk of injury when used on another appliance.
-
Appliance service must be performed only by qualified repair personnel. Service or maintenance performed by unqualified personnel may result in a risk of injury.
-
When servicing an appliance, use only identical replacement parts. Follow instructions in the Maintenance section of this manual. Use of unauthorized parts or failure to follow Maintenance instructions may create a risk of shock or injury.
-
Before cutting grass, remove foreign matter such as rocks and large sticks from the work area. Be careful not to catch foreign matter between blades, otherwise blades may be jammed. If this happens, switch the appliance off. Then remove the obstruction from the blades.
-
When not in use, be sure to cover the blades with blade cover.
-
If the blades stop moving due to the stuck of foreign objects between the blades during operation, switch off the tool and remove the battery cartridge, and then remove the foreign objects using tools such as pliers. Removing the foreign objects by hand may cause an injury for the reason that the blades may move in reaction to removing the foreign objects.
-
During operation, keep bystanders or animals at least 15 m (50 ft.) away from the tool. Stop the tool as soon as someone approaches.
-
Hold the tool firmly when using the tool.
-
Avoid unintentional starting. Do not carry the tool when the battery cartridge is installed and with finger on the switch. Make sure that the switch is off when installing the battery cartridge.
-
When not in use, attach the blade cover to the tool and store the tool indoors in dry, and high locked-up place, out of reach of children.
-
When attaching or removing the blade cover, be careful not to injure your hands.
-
Before operation, examine the work area for wire fences, stones, or other solid objects.
They can damage the blades. -
Check the hedges and bushes for foreign objects, such as wire fences or hidden wiring before operating the tool.
Battery tool use and care
-
Prevent unintentional starting. Ensure the switch is in the off-position before connecting to battery pack, picking up or carrying the machine. Carrying the machine with your finger on the switch or energizing machine that have the switch on invites accidents.
-
Disconnect the battery pack from the machine before making any adjustments, changing accessories, or storing machine. Such preventive safety measures reduce the risk of starting the machine accidentally.
-
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 machines 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 be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, seek medical help. Liquid ejected from the battery may cause irritation or burns.
-
Do not use a battery pack or machine 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 machine to fire or excessive temperature. Exposure to fire or temperature above 130°C (265°F) may cause explosion.
-
Follow all charging instructions and do not charge the battery pack or machine 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. -
Do not modify or attempt to repair the machine or the battery pack except as indicated in the instructions for use and care.
Electrical and battery safety
-
Do not dispose of the battery(ies) in a fire.
The cell may explode. Check with local codes for possible special disposal instructions. -

Released electrolyte is corrosive and may cause damage to the eyes or skin. It may be toxic if swallowed. -
Do not charge battery in rain, or in wet locations.
-
Do not charge the battery outdoors.
-
Do not handle charger, including charger plug and charger terminals with wet hands.
-
Avoid dangerous environment. Don’t use the machine in damp or wet locations or expose itto rain. Water entering the machine will increase the risk of electric shock.
