OPERATING INSTRUCTIONS

USING THE TOOL WITH DIFFERENT TRIGGERING OPTIONS

Complete all steps of PREPARING THE TOOL before using the tool.

This tool is shipped from the factory with a “single sequential actuation” trigger which will limit the tool to firing method number 1 only.

A “contact actuation” trigger is available. The “contact actuation” trigger allows the tool to be fired in either of two methods described below;

1.[SINGLE SEQUENTIAL ACTUATION TRIGGER]: To fire, grip tool firmly to maintain control, position nose of tool onto work surface, push the tool firmly against work surface to depress safety (S) Fig. 23, and squeeze trigger to fire a fastener. Allow tool to recoil away from work surface as fastener is driven. This “single sequential actuation” method provides the most accurate fastener placement.

-OR-

2.[CONTACT ACTUATION TRIGGER]: To fire, grip tool firmly to maintain control, squeeze and hold trigger, push the tool firmly against work surface. Allow tool to recoil away from work surface as fastener is driven. If safety element is allowed to recontact work surface before trigger is released an unwanted fastener will be fired. The tool will fire a fastener each time the safety is depressed. This method is known as “contact actuation” and allows very fast repetitive fastener placement.

IMPORTANT: A “contact actuation” trigger is available free-of-charge by calling 1-800-321-9443 in the United States and Canada or 001-731-660- 9374 outside the United States and Canada, and providing tool model and serial number. For identification purposes: the contact actuation trigger is black and the single sequential actuation trigger is red.

Disconnect tool from air supply before performing maintenance, clearing a jammed fastener, leaving work area, moving tool to another location, or handing the tool to another person.

Clean and inspect tool daily. Carefully check for proper operation of trigger and safety mechanism. Do Not use the tool unless both the trigger and the safety mechanism are functional, or if the tool is leaking air or needs any other repair.

The depth to which a fastener is driven is controlled by the depth adjustment knob (A) Fig. 24. The depth of drive is factory adjusted to a nominal setting. Test fire a fastener and check depth. If a change is desired, rotate the adjustment knob (A) Fig. 24. The adjustment knob has detents every 1/4 turn.

Rotate the knob (A) Fig. 24 clockwise

to increase the depth of drive, rotate

the knob counterclockwise to decrease the

 

depth of drive. Test fire another fastener and

 

check depth. Repeat as necessary to

 

achieve desired results. The amount of air

 

pressure required will vary depending on the

 

size of the fastener and the material being

 

fastened. Experiment with the air pressure

 

setting to determine the lowest setting that

 

will consistently perform the job at hand. Air

A

pressure in excess of that required can

 

cause premature wear and/or damage to the

Fig. 24

tool.

DA250B specifications

The Porter-Cable DA250B is a well-regarded tool in the world of pneumatic nailers, designed for those seeking efficiency, precision, and durability in their projects. This particular model is an 18-gauge brad nailer that excels in a variety of applications, such as trim work, cabinetry, and light woodworking. Its lightweight design and user-friendly features make it a popular choice among both professional contractors and DIY enthusiasts.

One of the standout characteristics of the DA250B is its powerful motor that drives nails from 5/8 inch to 2 inches in length. This range allows users to tackle a wide array of tasks, from affixing delicate trim to securing more substantial materials. The tool’s capacity to shoot brads at a rapid rate significantly enhances productivity, allowing projects to move forward without unnecessary delays.

The DA250B is equipped with a tool-free depth-of-drive adjustment feature, allowing users to easily adjust the depth of the nail without the use of additional tools. This ensures consistent results and minimizes the risk of over-driving or under-driving nails, both of which can compromise the aesthetic and structural integrity of finished work.

Another impressive feature is its integrated rear exhaust that effectively directs air away from the user and work surface, helping to keep both clean during operation. This design consideration is particularly important in a working environment where visibility and cleanliness are paramount.

The nailer also boasts a lightweight construction, weighing in at just over 3 pounds, which reduces user fatigue. The ergonomic grip and balanced design further enhance the comfort of the user during extended periods of work. Its robust aluminum housing adds to its durability, ensuring that the tool can withstand the rigors of frequent use on job sites.

Additionally, the DA250B incorporates a no-mar tip to prevent damage to the work surface, making it ideal for projects requiring a high level of finish quality. The magazine is easy to load, accommodating up to 100 brads, reducing downtime for reloading.

In conclusion, the Porter-Cable DA250B is a versatile, efficient, and durable brad nailer that offers an array of features designed to maximize productivity and ease of use. Its combination of power, precision, and user-friendly characteristics makes it a reliable choice for both professionals and hobbyists alike, ensuring that any project can be completed with confidence and finesse.
