Anti-Kickback Fingers

Anti-kickback fingers help prevent stock from being thrown from the machine. These fingers operate by gravity and should be inspected for pitch or gum buildup before each day's use. The fingers must operate freely and move independently for correct operation.

Infeed Roller

The function of the infeed roller is to feed the material into the machine. It is a corrugated, sectional roller with approximately 1/4" independent movement of each section to accomodate multiple board surfacing.

To provide proper drive, the infeed roller should be set so that the bottom of its arc is 1/16" (1.6mm) below the arc of the cutterhead knives. The infeed roller is under spring tension and this tension must be sufficient to feed the stock uniformly through the planer without slipping but should not be so tight that it causes damage to the stock. The tension should be equal at both ends of the roller.

To adjust the infeed roller:

1.Disconnect machine from power source.

2.Place a dial gauge under a knife in the cutterhead. (Figure 12 shows a Bed and Feed Roll Gauge – accessory #2230002 – which can be purchased from your dealer.)

3.If a dial gauge is not available, use a finished block of wood with notches cut out for the table rolls, in conjunction with a feeler gauge. See Figure 13 for an example of a wood block you can make and use as a gauge.

4.Raise the table with the handwheel until the gauge contacts a knife at the apex of its curve. Zero the gauge at that position.

5.Move the gauge to the extreme left end of the infeed roller and check the measurement. It should be 1/16” below the knife measurement.

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.
