5.If the gauge reading is greater or less than zero, reach beneath the table with a wrench and loosen the hex nut (C, Figure 17) which is above the cam (D, Figure 17) near the end of the roller that needs adjusting. Rotate the hex cap screw (E, Figure 17) until the gauge reads zero.

6.Repeat the process for the left side of the table roller, and then re-check the right side. It is important that both ends of the table roller be the same height to help prevent skewing of the board as it feeds through the machine.

7.Re-tighten the hex nuts (C, Figure 17) on both ends of the table roller.

8.Repeat the procedure for the second table roller.

Table Adjustments

The planer table is raised and lowered by twin screws supported on bearings, and is guided by machined surfaces on the side panels. The fit- up to prevent the table from rocking is controlled by two gibs in front. See Figure 18. These gibs are pre-set at the factory and require no attention. If, after extensive use of the planer, some looseness in the table develops, these gibs can be adjusted individually using the gib screws provided so that the ways are lightly contacting on all four surfaces. The gibs should be tight enough to prevent rocking or movement of the table when the planer is in operation.

To perform accurate planing, the table must be parallel with the cutterhead. Lack of parallelism results in a taper over the width of the board. To check parallelism do the following:

1.Place a gauge on the table and contacting a knife at the apex of its arc. Do this at each end of the cutterhead and compare the measurements.

2.If the table is not parallel to the cutterhead, place the gauge at the end that needs to be raised.

3.Loosen the three socket head cap screws (A, Figure 19) beneath the table.

4.Place a rod-like object (such as a hex wrench) into one of the open holes (B, Figure 19) and turn the shaft (C, Figure 19) to raise the table until the gauge reads the proper measurement. Or, the same effect can be achieved by lowering the other side of the table.

5.Re-tighten the screws (A, Figure 19).

NOTE: This adjustment may generate the need to recalibrate the table height pointer.

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.
