Safety Instructions

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 carryingthe tool. Carrying power tools with your finger on the switch or energizing 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 jewelry. Keep your hair, clothing and gloves away from moving parts.Loose clothes, jewelry 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.
  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 remove the battery pack, if detachable, 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 and accessories. 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 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.

•  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.
  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 behavior 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 (130 °C) 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.

•  Never service damaged battery packs. Service of battery packs should only be performed by the manufacturer or authorized service providers.

Transportation

Shipping the DeWALT FLEXVOLT™ Battery Pack
The DeWALT FLEXVOLT™ battery pack has a battery cap that should be used when shipping the battery pack. Attach the cap to the battery pack to ready it for shipping. This converts the battery pack to three separate 20V batteries. The three batteries have the Watt-hour rating labeled “Shipping” on the battery pack. If shipping without the cap or in a tool, the pack is one battery at the Watt hour rating labeled “Use”. In this example, the battery pack is three batteries with 40 Watt-hours each when using the cap. Otherwise, the battery pack is one battery with 120 Watt hours.

Safety Instructions for All Battery Chargers

•  DO NOT attempt to charge the battery pack with any chargers other than a DeWALT charger. DeWALT chargers and battery packs are specifically designed to work together.
  These chargers are not intended for any uses other than charging DeWALT rechargeable battery packs. Charging other types of battery packs may cause them to overheat and burst, resulting in personal injury, property damage, fire, electric shock or electrocution.

•  Do not expose the charger to rain or snow.

•  Do not allow water or any liquid to enter charger.

•  Pull by the plug rather than the cord when disconnecting the charger. This will reduce the risk of damage to the electric plug and cord.

•  Make sure that the cord is located so that it will not be stepped on, tripped over or otherwise subjected to damage or stress.

•  Do not use an extension cord unless it is absolutely necessary. Use of improper extension cord could result in risk of fire, electric shock or electrocution.

•  When operating a charger outdoors, always provide a dry location and use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.

•  An extension cord must have adequate wire size (AWG or American Wire Gauge) for safety. The smaller the gauge number of the wire, the heavier the cord and thus the greater its capacity. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. The following table shows the correct size to use depending on total length of all extension cords plugged together, and nameplate ampere rating. If in doubt, use the next heavier gauge.

MAINTENANCE

Your DeWALT power tool has been designed to operate over a long period of time with a minimum of maintenance. Continuous satisfactory operation depends upon proper tool care and regular cleaning

Blade Maintenance
The cutting blades are made from high quality, hardened steel and with normal usage, they will not require resharpening. However, if you accidentally hit a wire fence (Fig. J), stones, glass, or other hard objects, you may put a nick in the blade. There is no need to remove this nick as long as it does not interfere with the movement of the blade. If it does interfere, remove the battery and use a fine toothed file or sharpening stone to remove the nick. If you drop the trimmer, carefully inspect it for damage. If the blade is bent, housing cracked, handles broken or if you see any other condition that may affect the tool’s operation contact your local authorized service center for repairs before putting it back into use.

Blade Lubrication
