The Planer is used to trim wood boards down by precise measurements, never more than 1/16 of an inch. This heavy duty planer offers performance and value, loaded with standard features not found on other machines in its class. The powerful 5HP motor and 20" planing capacity will handle the most demanding work. The helical cutterhead provides quieter operation and finer finishing than conventional systems, and the four-sided knife inserts seat themselves without requiring a set-up gauge. The 5" dust port connects easily to any dust collector. The anti-kickback fingers and pressure bar are located in close proximity to the cutterhead for an exceptional finish. The solid cast iron base, table and head are designed for production. The 2-speed oil bath gearbox transmits full power to feed rollers and facilitates fast speed changes at 24 and 31 FPM. The gearbox can be changed to 4-speed with the included gear to run lower speeds of 16 and 20 FPM. The corrugated infeed and fine groove outfeed rollers ensure a smooth feed. The precision ground and polished cast iron table rides on four steel columns giving it plenty of support for the larger workpiece. Heavy cast iron extension wings ensure a flat, smooth cut.
The demonstration for this machine will be to plane both sides of scrap piece of wood from the woodshop. It would be preferable to use a piece of would that is warped in some way to understand the process of planning each side.
- Connect and turn the one of the dust collectors (shown below) on so we can keep the place clean. Ensure that the restriction plate is “out”.
- The planer has two feed speeds, typically, the 24 fpm is used whenever possible. For softwood, the 31 FPM setting can be used.
- Before turning machine on, adjust wheel to feed in work piece and adjust wheel back down to fit snuggly.
- Remove piece and adjust wheel to trim desired amount off of work piece.
- Do not attempt to remove more than 1/16” per pass (one turn). Do not over load motor. Multiple passes result in less tear-out and are easier on the machine.
- Always determine the thickness of the thickest part of the board and adjust planer to match this thickness.
- Do not attempt to pass stock less than 12” in length through the planer.
- Turn the Thickness Planer on and wait until it has reached full speed before starting to plane your stock.
- Only plane one piece of stock at a time. Stand to the side of the stock and feed it into the infeed opening. Let go of the stock when the roller takes hold of it.
- Always plane with the grain, never perpendicular to grain (i.e., feed boards lengthwise, not width-wise).
- Never attempt to force feed the planer; always allow stock to move through under the force of the feed roller only.
- Stock will sometimes “hang” (or stop moving forward). Causes and solutions are:
- The pressure bar is causing too much pressure on the wood. To fix, simply raise the pressure bar lever slightly and your stock should continue on its path. When it starts moving again, gently put the pressure bar lever back down.
- The feed control may have slipped. Simply push it all the way to the right.
- The table is too high (not adjusted to the proper height). This should NOT happen since you’re supposed to measure the stock and then make table adjustment according to your needs.
- Never attempt to reverse feed stock.
- Be careful not to let your fingers become pinched between stock and table.
- If stock is real long, get help holding it while you feed it into the infeed opening. Ensure your helper is standing to the side of the stock and NOT behind it.
- Keep your full attention on the stock, the controls, and where your hands/fingers are while you plane.
- After half of the stock has entered the planer, walk around back and hold the end up as the rest of the stock comes out of the machine. Do not pull the stock out; simply allow the machine to push it toward you. Adjust the pressure bar lever if needed.
- Do NOT plane to a thickness less than 3/8”.
- Listen to the sound the planer makes as it’s operating. If something doesn’t sound right, turn the Thickness Planer off and notify the shop aid.
- Always turn the Thickness Planer off and wait until it stops moving before making any adjustments.

The Powermatic planer contains a 5HP motor and 20" planing capacity that will handle the most demanding work. The helical cutterhead provides quieter operation and finer finishing than conventional systems, and the four-sided knife inserts seat themselves without requiring a set-up gauge. The 5" dust port connects easily to any dust collector. Used to remove material from wood, as well as squaring to create straight pieces.
