General Safety Instructions

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.

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.
• 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.

Personal Safety

• Always wear eye protection. Use safety glasses or goggles.
• Dress properly. Do not wear loose clothing or jewelry. Keep your hair and clothing away from moving parts.
• Stay alert, watch what you are doing, and use common sense when operating a power tool.

Setup

Unpacking

Carefully remove the screw gun and any accessories from the packaging. Inspect the tool for any damage that may have occurred during shipping. Do not discard packaging until you are sure all components are present and the tool is in good condition.

Inserting a Bit

1. Ensure the screw gun is unplugged from the power source before inserting or removing bits.
2. Pull back the collar on the 1/4-inch quick-change bit holder.
3. Insert the desired 1/4-inch hex shank bit fully into the bit holder.
4. Release the collar to lock the bit in place. Gently pull on the bit to ensure it is securely seated.

Power Connection

Connect the screw gun's power cord to a standard 120V AC electrical outlet. Ensure the outlet is properly grounded.

Operating Instructions

Starting and Stopping

• To start the tool, depress the two-finger trigger. The speed is variable depending on how far the trigger is pressed.
• To stop the tool, release the trigger.

Variable Speed Control

The screw gun features a variable speed trigger. Light pressure on the trigger results in lower speeds, while increasing pressure increases the speed up to the maximum 2,500 RPM. This allows for precise control when starting screws or working with delicate materials.

Forward/Reverse Operation

A forward/reverse switch is located near the trigger. Push the switch to the left for forward rotation (driving screws) and to the right for reverse rotation (removing screws). Always ensure the tool has come to a complete stop before changing the direction of rotation.

Using the Positive Clutch

The positive clutch engages when pressure is applied to the screw gun, pushing the bit into the fastener. This mechanism helps prevent over-tightening and stripping of screw heads. Apply firm, steady pressure to the tool to engage the clutch and drive the screw. Release pressure once the screw is seated to disengage the clutch.

Driving Screws

1. Select the appropriate bit for your screw type.
2. Place the screw on the bit tip.
3. Position the screw gun perpendicular to the workpiece.
4. Apply firm, steady pressure to the tool and slowly depress the trigger to start the screw.
5. Increase trigger pressure as the screw enters the material, maintaining consistent forward pressure until the screw is fully seated.
6. Release pressure and the trigger to stop the tool.

Maintenance

Regular maintenance ensures optimal performance and extends the life of your DEWALT DW281 Screw Gun.

Cleaning

• Always unplug the tool before cleaning.
• Use a clean, dry cloth to wipe down the exterior of the tool.
• Periodically clean the ventilation openings to prevent overheating. Do not use solvents or harsh chemicals.

Inspection

• Regularly inspect the power cord for damage. If damaged, have it replaced by a qualified service technician.
• Check the bit holder for wear or damage. Replace if necessary to ensure secure bit retention.
