General Power Tool Safety Warnings

WARNING Read all safety warnings and all instructions. Failure to follow the warnings and instructions 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 mains-operated (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 anextension 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 residual current device (RCD) protected supply. Use of an RCD 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 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 yourfinger 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 mayresult 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, clothing and gloves 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 dustcollection can reduce dust-related hazards.

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 toolaccidentally.
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 cutting tools sharp and clean. Properlymaintained 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.

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.

Safety Instructions For Tackers

Tacker Safety Warnings

Always assume that the tool contains fasteners. Careless handling of the tacker can result in unexpected firing of fasteners and personal injury.
Do not point the tool towards yourself or anyone nearby. Unexpected triggering will discharge the fastener causing an injury.
Do not actuate the tool unless the tool is placed firmly against the workpiece. If the tool is not in contact with the workpiece, the fastener may be deflected away from your target.
Disconnect the tool from the power source when the fastener jams in the tool. While removing a jammed fastener, the tacker may be accidentally activated if it is plugged in.
Use caution while removing a jammed fastener. The mechanism may be under compression and the fastener may be forcefully discharged whileattempting to free a jammed condition.
When fastening electrical cables, make sure the cables are not energized. Hold the tacker only by insulated gripping surfaces. Use only fasteners designed for electrical cable installations. Inspect that the fastener has not damaged the insulation of the electrical cables. A fastener that damages the insulation of electric cables can lead to electric shock and fire hazards.

Sumbols

ELECTRICAL CONNECTION

Your DEWALT® Electric Stapler/Nailer operates on 120 volt, 60 Hertz alternating current. The outlet should be rated for 6.4 Amps.

TRIGGER OPERATION

Trigger is located on the bottom of the handle. Each pull of the trigger will result in one complete cycle; that is the drive and return stroke are completed before it is possible to release the trigger. Make sure your finger is not on the trigger when connecting the tool to the power supply. A staple/brad cannot be fired unless the stapling tacker is pressed against a work surface. This engages a contact fire safety switch which is located on the bottom of the gun.

FEATURES

Double Insulation: This eliminates the need for a three-wire grounded power cord yet offers equal protection to a grounded tool. Plug your stapling tacker into any 120 volt AC outlet.
HI-LO Power: DEWALT® Electric Stapler/Nailer has power adjustment. Use the HI setting to drive staples/brad nails into hard materials or use the LO setting to drive staples/brads into thin or soft materials without going all the way through them.
Easy Loading: The sliding base allows for easy loading and unloading of staples/brad nails by simply squeezing the latch and pulling.
On/Off Switch: Allows the tool to be easily shut off when not in use.
Contact-Fire Safety Switch: A staple/brad nail cannot be fired unless the stapling tacker is pressed against a work surface.

LENGTH OF BRAD STRIP

The tool uses brad strips that are 4 1/2″ long. We recommend breaking them in half before loading into the tool.

USE OF EXTENSION CORDS

Make sure extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current the tool will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. Table 1 shows the correct size to use depending on cord length and name plate ampere rating. If in doubt, use the next heavier gauge. The smaller the gauge number (AWG), the heavier the cord. When tool is used outdoors, use only extension cords intended for outdoor use and so marked.
