Functional Description

3.Grounded, cord-connected machines intended for use on a supply circuit having a nominal rating between

150- 250 volts, inclusive:

If the machine is intended for use on a circuit that has an outlet that looks like the one illustrated in Fig. C, the machine will have a grounding plug that looks like the plug illustrated in Fig. C. Make sure the machine is connected to an outlet having the same configuration as the plug. No adapter is available or should be used with this machine. If the machine must be re-connected for use on a different type of electric circuit, the re- connection should be made by qualified service personnel; and after re-connection, the machine should comply with all local codes and ordinances.

IN ALL CASES, MAKE CERTAIN THE R E C E P TA C L E I N Q U E S T I O N I S P R O P E R LY GROUNDED. IF YOU ARE NOT SURE HAVE A Q U A L I F I E D E L E C T R I C I A N C H E C K T H E RECEPTACLE.

EXTENSION CORDS

Use proper extension cords. Make sure your extension cord is in good condition and is a 3-wire extension cord which has a 3-prong grounding type plug and matching receptacle which will accept the machine’s plug. When using an extension cord, be sure to use one heavy enough to carry the current of the machine. An undersized cord will cause a drop in line voltage, resulting in loss of power and overheating. Fig. D, shows the correct gauge to use depending on the cord length. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

28-475X, 28-248 specifications

The Porter-Cable 28-248 and 28-475X are two impressive models from Porter-Cable, a brand known for its high-quality power tools that cater to the needs of both professionals and DIY enthusiasts. These models are designed to deliver reliable performance, durability, and innovative features suitable for a wide range of applications.

The Porter-Cable 28-248 is a 28-gauge pneumatic brad nailer. This tool is compact and lightweight, making it easy to maneuver in tight spaces. One of its standout features is the tool-free depth of drive adjustment, allowing users to modify the depth of the nails without additional tools. This is particularly useful when working with different materials or when precision is paramount.

The 28-248 is equipped with a rear exhaust that directs air away from the user, keeping the workspace clean and enhancing comfort during operation. The integrated power adjustment dial lets users adjust the power depending on the material being used, providing versatility across various projects. Additionally, the 28-248 features a reload indicator that signals when it's time to refill the magazine, preventing interruptions during work.

On the other hand, the Porter-Cable 28-475X is a more robust option designed for industrial applications. It is a 27-gauge nail gun that offers a higher capacity magazine for less downtime. The 28-475X features a stainless steel magazine that ensures durability and smooth operation while reducing the risk of jams.

This model also includes a selective actuation switch, allowing users to choose between sequential and contact firing modes based on their needs. The built-in dry fire lockout mechanism is another valuable feature that prevents the tool from firing without nails, which prolongs its lifespan and ensures safety.

The ergonomic design of both models emphasizes user comfort, with features like rubber grips that minimize fatigue during prolonged use. Both tools are compatible with a variety of nail sizes and types, making them suitable for a range of tasks from cabinetry to flooring installations.
