The planer is the jointers other half. It's first use is to make the opposing surface of a 'jointed' board both flat and parallel (coplanar). It is also used bring boards to a desired thickness. Did you make a cutting board with a few high spots? No need to spend hours sanding it down, just send it through the planer!
Safety practices to remember before operating the planer:
Inspect the material. Make sure it is free of all knots, cracks, sand, nails, glues, paint, and other foreign material.
Never adjust the machine to take a cut of more than 1/16”.
The shortest stock that can be planed safely is 14 inches, or the distance between the in feed and out feed rollers plus two inches. Sorter stock “kicks back.”
Surface one board at a time unless the machine is equipped with a sectional in feed roller.
Never plane stock less than ¼” thick.
Safety practices to follow when operating the planer:
Obtain permission from the instructor before starting the planer.
Stand to one side to avoid chips that may be thrown back with great force.
Watch the position of your fingers when inserting a board into the planer. Fingers can easily be pinched when the in feed rollers first grip the material and force it against the table.
If the planer does not operate correctly or if a board becomes stuck under the cutter, LOWER THE TABLE 1/8 TURN OF THE WHEEL, TURN OFF THE POWER AND CALL THE INSTRUCTOR.
