- Never plane lumber that is coated with a finish, such a lacquer or paint. Also, never plane lumber that has screws, nails, staples, etc. attached. A good "rule of thumb" is to never plane used lumber.
- Never plane lumber unless it has at least one flat surface. If it doesn't, a jointer should be used to true the surface.
- Always feed lumber into the planer so that the cutting will be done with the grain of the wood.
- The wood stock should be at least 2" longer than the distance between the infeed and the outfeed rolls. That distance will depend upon the size and make of your planer. For our class 12" is a safe length of lumber to be planed.
- Never plane more than 1/16" for each cut. Set the desired thickness to be cut by turning the elevating handwheel. Tighten the handwheel lock before inserting lumber into the planer. Repeat this process for each cut, until the desired lumber thickness us achieved.
- Never look into the planer while the power in on.
- Always stand to one side of the lumber while it is being feed through the planer.
- If a board gets stuck in the planer, stop the machine immediately. Once the planer has come to complete stop, lower the bed and use another piece of lumber to push the stuck piece through.
- When finished using the planer, turn off the power and pull on the brake until the feed rolls and cutter head has stopped rotating.
- Never Plane stock that has loose knots.
