Pressure Rollers

The pressure rollers (Fig. 10) maintain tension upon the workpiece as it passes through the machine. The spring tension of the pressure rollers has been factory set. If a board refuses to pass through the machine, or the finished surface of a board is uneven, the spring tension of the pressure rollers may need adjusting.

1.Loosen the hex nut (A, Fig. 10).

2.Place a 17mm wrench over the flat on the adjusting screw (B, Fig. 10) and lower the screw to increase the roller pressure on the workpiece; or raise the screw to decrease the pressure.

3.Retighten hex nut (A, Fig. 10).

4.Repeat this same adjustment at the opposite end of the roller to maintain parallel.

5.Repeat procedure for other two pressure rollers.

Do not over tighten the adjusting screw, as excess roller pressure will prevent the workpiece from passing through the machine, and may cause the conveyor belt to stop.

Table Height

Rotate the handwheel until the depth gauge (Fig. 11) reads the appropriate depth. One revolu- tion of the handwheel moves the table approxim- ately 1/16”.

A limit plate (Fig. 11) is mounted to the front of the sander. If the table has been set too high, the workpiece will contact this plate and a limit switch will shut off the conveyor table. If this happens, re- position the table and restart the machine.

Table Parallelism

The conveyor table has been set parallel to the drums at the factory. If the conveyor table should ever need adjusting to bring it back into parallel with the drums, proceed as follows:

1.Remove the front cover plate below the table to expose the chain. Also remove the rear cover plate.

2.Loosen the socket head cap screw on the chain tensioner (Fig. 12) and slide the chain tensioner assembly forward to slacken the chain.

3.Remove the chain from around all four sprockets.

DDS-225, DDS-237 specifications

The Powermatic DDS-237 and DDS-225 are two advanced drill presses that have been engineered for woodworkers who demand precision and versatility in their projects. These machines are part of Powermatic’s commitment to providing high-quality tools that cater to both professional and hobbyist woodworkers.

One of the main features of the DDS-237 is its robust construction. With a heavy-duty cast iron base and column, this drill press offers exceptional stability, reducing vibrations during operation which leads to accurate drilling. The DDS-225 follows suit, providing a durable design that ensures reliability even in the most challenging work environments.

The DDS-237 comes equipped with a powerful 1 HP motor, offering variable speed control ranging from 250 to 3000 RPM, allowing users to select the perfect speed for various materials. This feature is particularly advantageous for woodworkers who work with different species of wood or even metal and plastic. The DDS-225, on the other hand, features a slightly less powerful motor but maintains the same level of versatility with multiple speed settings.

Another significant aspect of these drill presses is their user-friendly interface and adjustments. Both models boast an easy-to-read digital depth gauge, enabling precise depth adjustments. This feature is crucial for applications requiring repetitive drilling depths, such as doweling or creating mortises.

Both models also incorporate innovative technologies aimed at enhancing user safety and convenience. The patented Quick-Release chuck system allows for rapid and easy tool changes without the need for additional tools, saving valuable time during setup and operation. Furthermore, the built-in work light illuminates the workspace, improving visibility during intricate drilling tasks.

Dust collection is also a fundamental aspect of both models, with integrated ports designed to minimize debris in the workspace, creating a healthier and cleaner working environment.

The Powermatic DDS-237 and DDS-225 are not just machines but essential tools that combine power, precision, and safety. Whether for professional use or serious woodworking enthusiasts, these drill presses are designed to meet the demands of any project with reliability and efficiency.
