6.If it is not 1/16” below the knife, correct by loosening the hex nut and turning the adjustment screw (A, Figure 14) with a hex wrench.

7.Move the gauge to the extreme right end of the infeed roller and check. Make similar adjustments if needed.

8.Tighten hex nuts (A, Figure 14) when finished.

IMPORTANT: The setting on both ends of the infeed roller must be the same to avoid skewing of the material as it is fed through the machine.

Chipbreaker

The chipbreaker is a sectionalized type made of spring-loaded sections mounted on a bar, which complements the sectional infeed roller. The functions of the chipbreaker are to break chips into small pieces, help avoid splintering of the wood, help avoid board bounce on thinner boards, to direct the flow of chips out of the machine, and to permit multiple board surfacing.

The chipbreaker has been factory set at 1/32” (0.8mm) below the cutting arc of the knives, and has been spring-tensioned properly.

A chipbreaker set too low or with excessive tension may prevent stock from feeding into the machine.

Pressure Bar

Most planing problems can be traced to improper setting of the pressure bar. Its function is to hold down the material after it passes under the cutterhead and throughout the remainder of the cut. Its basic setting is to be in line with the arc of the cutterhead knives.

If the pressure bar is too high, a shallow "clip" will occur at each end of the board. If it is too low, stock will not feed through.

Use a gauge to set the full length of the pressure bar to be .000-.001" (.02mm) below the arc of the cutterhead.

(C)and the spring tension adjustment screw (D) for the pressure bar. Loosen the hex nut and rotate the screw as needed. Make sure the setting on both ends of the pressure bar is the same. Tighten the hex nuts when adjustment is complete.

This initial setup is a starting point and final adjustment may have to be made during a test cut.

201HH specifications

The Powermatic 201HH is a highly regarded 8-inch jointer, renowned for its robust construction, precision, and advanced technology. This machine is particularly well-suited for both professional woodworkers and serious hobbyists who demand the best performance from their tools.

One of the standout features of the Powermatic 201HH is the Helical Cutterhead. This technology distinguishes it from standard jointers featuring straight knives. The helical design incorporates numerous small, square inserts that can be rotated or replaced when worn, significantly extending the overall life of the cutterhead. The helical arrangement reduces noise during operation and provides a much smoother finish on the workpiece, minimizing the need for additional sanding.

Adjustability is another area where the Powermatic 201HH excels. It boasts an easy-to-use tables adjustment mechanism that allows users to fine-tune the infeed and outfeed tables for precise jointing. This feature is essential to ensure a perfectly flat and even surface on all types of wood. The large tables, measuring 74 inches in length, provide ample support for larger workpieces, making it easier to manage and maneuver materials during operation.

The 201HH also comes equipped with a powerful 3 HP motor that drives the machine with reliability and performance. This motor is a key component in delivering consistent power and maintaining speed even under heavier workloads. Coupled with a strong base and solid construction, the jointer maintains stability during operation, which contributes to both safety and precision.

Added convenience comes in the form of an integrated dust collection port, which facilitates cleaner operation by effectively managing sawdust and shavings. This reduces cleanup time and creates a more pleasant working environment.

Moreover, the design of the Powermatic 201HH incorporates safety features, including a push block that assists in guiding stock through the machine, minimizing the risk of injury. The solid build quality and attention to detail in the engineering provide confidence to users that they are working with a reliable tool that will stand the test of time.

In summary, the Powermatic 201HH offers an impressive array of features including a helical cutterhead, extensive adjustability, a powerful motor, efficient dust collection, and strong safety measures. These characteristics make it a top choice for anyone looking to achieve exceptional results in their woodworking projects.
