Use the guard and sled to cover the jointer's knives

Step 1: Using the Guard

The adjustable guard covers the knives and keeps fingers away. The yellow arm at the end of the guard moves when the board is slid against it. It will lift up or slide the to the side, depending on orientation.

When jointing the face of the board, the arm should be vertical.

  • This board will slide under the guard, causing it to rise.
  • Always use a push stick when face jointing.
  • If the board is thicker than 3”, it must be run next to the guard (horizontal arm position).

When jointing the edge of the board, the arm should be horizontal.

  • This board will force the guide to slide sideways on the table.

Step 2: Using the Large Capacity Push Stick

The large capacity push stick is the best tool to use for jointing the face of a wide, thin board. It should be used with any board 1" thick or less.

  1. Place the large capacity push stick flat on the board.
  2. Put the yellow arm in the vertical position.
  3. Push the board through, using the handles on the large capacity push stick.
  4. When the plastic blade on the large capacity push stick hits the yellow arm, the arm will move to the horizontal position.

Step 3: Fence Adjustment

The fence has two adjustments; width and angle.

To move the fence closer to (or further from) the operator, unlock the width lock and move the fence to the desired location.

To put an angled cut (a chamfer) on the edge of a board, the fence can be angled. Unlock the angle lock, change the angle and re-lock.

Return the fence to 90 degrees after use. Use a machinist's square.

Step 4: Guard Adjustment

To help keep the guard from taking too much space near the machine, it can be folded.

Slide the black tab to unlock and hinge the guard.

Always adjust the guard so it touches the fence; this will keep the knives covered.

Never leave the knives uncovered.

Step 5: Machining Curved Hardwood

If the board is bowed, warped or cupped, place the high point up. It may take multiple passes to make the board flat. If you are working from Pier 9, ask Shop Staff for best methods. If you are working from a different studio, refer to the jointer's manual for best practices.
