GENERAL POWER TOOL SAFETY WARNINGS

WARNING!
Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury.

Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your mainsoperated (corded) power tool or battery-operated (cordless) power tool.

WORK AREA SAFETY

Keep work area clean and well lit. Cluttered or dark areas invite accidents.
Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

ELECTRICAL SAFETY

Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.
Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
If operating a power tool in a damp location is unavoidable, use a ground fault circuit interrupter (GFCI) protected supply. Use of a GFCI reduces the risk of electric shock.

PERSONAL SAFETY

Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.
Use personal protective equipment. Always wear eye protection. Protective equipment such as a dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energising power tools that have the switch on invites accidents.
Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
Dress properly. Do not wear loose clothing or jewellery. Keep your hair and clothing away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards.
Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.
Do not wear loose clothing or jewelry. Contain long hair. Loose clothes, jewelry, or long hair can be drawn into air vents.
Do not use on a ladder or unstable support. Stable footing on a solid surface enables better control of the power tool in unexpected situations.
Wear heavy, long pants, long sleeves, boots, and gloves. Do not wear loose fitting clothing, short pants, sandals, or go barefoot. Do not wear jewelry of any kind.

POWER TOOL USE AND CARE

Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.
Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.

BATTERY TOOL USE AND CARE

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 power tools 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, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.
Do not use a battery pack or tool 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 tool to fire or excessive temperature. Exposure to fire or temperature above 265°F may cause explosion.
Follow all charging instructions and do not charge the battery pack or tool outside the temperature range specified in the instructions. Charging improperly or at temperatures outside the specified range may damage the battery and increase the risk of fire.

SERVICE

Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.
When servicing a power tool, 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.
Never service damaged battery packs. Service of battery packs should only be performed by the manufacturer or authorized service providers.

HEDGE TRIMMER SAFETY WARNINGS

Keep all parts of the body away from the cutter blade. Do not remove cut material or hold material to be cut when blades are moving. Make sure the switch is off when clearing jammed material. Blades coast after turn off. A moment of inattention while operating the hedge trimmer may result in serious personal injury.
Carry the hedge trimmer by the handle with the cutter blade stopped. Proper handling of the hedge trimmer will reduce possible personal injury from the cutter blades.
Do not use the grass shear in bad weather conditions, especially when there is a risk of lightning. This decreases the risk of being struck by lightning.
Keep all power cords and cables away from cutting area. Power cords or cables may be hidden and can be accidentally cut by the blade.
When clearing jammed material or servicing the grass shear, make sure the power switch is off and the battery pack is removed or disconnected. Unexpected actuation of the grass shear while clearing jammed material or servicing may result in serious personal injury. (Edit to indicate the power tool versus grass shear.)
Hold the power tool by insulated gripping surfaces only, because the cutter blade may contact hidden wiring. Cutter blades contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.
DANGER — Keep hands away from blade. Contact with blade will result in serious personal injury.
Maintain a firm grip on handle while cutting.
Always wear eye protection with side shields marked to comply with ANSI Z87.1. Following this rule will reduce the risk of serious personal injury.
Clear the area to be cut before each use. Remove all objects such as cords, lights, wire, or loose string which can become entangled in the cutting blade and create a risk of serious personal injury.
Before starting the power tool, make sure the blade is not in contact with any object.
Stop the unit, remove the battery pack, and make sure the blade has stopped before setting the unit down.
Never cut any material with a diameter larger than 5/16 in.
Always stop the motor when cutting is delayed or when walking from one cutting location to another.
Keep unit clean of clippings and other materials. They may become lodged in the cutting blades.
Store the unit inside in a dry place, either locked up or up high to prevent unauthorized use or damage. Keep out of the reach of children or untrained individuals.
Replace blade cover when unit is not in use.
Never douse or squirt the unit with water or any other liquid. Keep handles dry, clean, and free from debris. Clean after each use; see storage instructions.
Secure the unit while transporting.
Battery operated units do not have to be plugged into an electrical outlet; therefore, they are always in operating condition. Be aware of possible hazards even when unit is not operating.
Remove the battery pack before making any adjustments, cleaning, storing, or removing material from the unit, or when not in use.
When transporting or storing the power tool always fit the cutting device cover.
Use this product only with batteries and chargers listed in tool/appliance/battery pack/charger correlation supplement 987000-432.

STARTING AND STOPPING

See Figure 4.
To start:

Depress the lock-out button.
Depress the switch trigger.
To stop:
Release the switch trigger.

CUTTING TIPS
See Figures 5 – 6.

WARNING:
Never cut near electric cords or lines. If blade jams on any electrical cord or line, DO NOT TOUCH THE BLADE! IT CAN BECOME ELECTRICALLY LIVE AND VERY DANGEROUS. Continue to hold the grass shear/shrubber by the handle or lay it down and away from you in a safe manner. Disconnect the electrical service to the damaged line or cord before attempting to free the blade from the line or cord. Contact with the blade, other conductive parts of the grass shear/shrubber, or live electric cords or lines will result in death by electrocution or serious injury.

WARNING:
Clear the area to be cut before each use. Remove all objects such as cords, lights, wire, or loose string which can become entangled in the cutting blade and create a risk of serious personal injury.

Never use the grass shear/shrubber near power lines, fencing, posts, buildings, or other immovable objects.
Do not force the grass shear/shrubber through heavy grass or shrubbery. This can cause the blades to bind and slow down. If the blades slow down, reduce the pace.
When using the grass shear, never cut anything heavier than blades of grass or pulpy stalks and stems. Woody stems and twigs can jam or bend the shear blades.
Do not attempt to cut stems or twigs with the shrubber blade that are larger than 5/16 in. thick, or those obviously too large to feed into its cutting blade. Use a non-powered hand saw or pruning saw to trim large stems.
If blades do become jammed, stop the motor, allow the blades to stop, and remove the battery pack before attempting to remove the obstruction.
If desired, you can use a string to help cut your hedge level. Decide how high you want the hedge. Stretch a piece of string along the hedge at the desired height. Trim the hedge just above the guide line of string. Trim the side of a hedge so that it will be slightly narrower at the top. More of the hedge will be exposed when shaped this way, and it will be more uniform.
Wear gloves when trimming thorny or prickly growth. When trimming new growth, use a wide sweeping action, so that the stems are fed directly into the cutting blade. Older growth will have thicker stems and will be trimmed easiest by using a sawing movement.

OPERATING THE GRASS SHEAR/SHRUBBER

See Figures 5 – 6.

Depending on the application, stand or kneel in a stable position next to the cutting area.
Inspect and clear the area of any hidden objects.
Grasp the handle firmly and start the grass shear/shrubber.
Using a slow, sweeping action begin cutting from side to side.
If the blade hits a hard object, stop the motor, allow the blades to stop, and remove the battery pack. Inspect the blade for damage. Do not use if any damage is detected.
Do not continue use until any damaged item has been repaired or replaced.
Failure to do so may result in loss of function.
