7.Rotate the cutterhead using the belt or pulley, and repeat steps 2 through 6 for each of the remaining three knives.

8.When all four knives have been installed and made snug, begin the tightening process.

NOTE: All knives and gibs should be in place before tightening. Tightening one knife in without the others in position can cause cutterhead distortion.

9.The tightening process should proceed working from the center outward on each knife. Go once around the cutterhead further tightening all gib screws in sequence. Then repeat the same sequence a second time, this time fully tightening all screws.

After installing knives, re- check all gib screws for tightness. Loose gib screws can result in knives being thrown from the cutterhead, causing severe damage to the machine and possible serious or fatal injury to the operator or bystanders.

Replacing or Rotating Knife Inserts (Helical Cutterhead only)

The knife inserts on the model 201HH are four- sided. When dull, simply remove each insert, rotate it 90° for a fresh edge, and re-install it.

No set-up gauge is necessary for the inserts. Use the provided star point screwdriver to remove the knife insert screw. See Figure 10. It is advisable to rotate all inserts at the same time to maintain consistent cutting. However, if one or more knife inserts develops a nick, rotate only those inserts that are affected.

Each knife insert has an etched reference mark so that you can keep track of rotations.

IMPORTANT: When removing or rotating inserts, clean saw dust from the screw, the insert, and the cutterhead platform. Dust accumulation between these elements can prevent the insert from seating properly, and may affect the quality of the cut.

Before installing each screw, lightly coat the screw threads with machine oil and wipe off any excess.

Securely tighten each screw which holds the knife inserts before operating the planer!

Make sure all knife insert screws are tightened securely. Loose inserts can be propelled at high speed from a rotating cutterhead, causing injury.

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.
