1.   Be careful you do not run any material that might have nails, screws, etc, through the jointer.  It not only can damage the machine, but it may cause the work to be thrown out and hurt you.

 

2.   Always see that the jointer is set to the correct depth before making a cut.  If it is set too deep, the work can be jerked out of your hands.

 

3.   You must not use the jointer for flat work that is less than ½” thick.  Thin stock cannot be held down against the cutter head and are liable to break.

 

4.   You must not use the jointer for work that is less than 12” long.  If the front corner should tip into the cutter head, it can be flipped out of the machine and your hands could slide into the cutters.

 

5.   Always use a safety shoe or push stick when running the flat side of a board through the jointer.  This will keep your fingers from getting too close to the cutter head.

 

6.   You must use a push stick when jointing pieces of wood 3” wide or less.  This will keep your fingers from getting too close to the cutter head.

 

7.   Do not use the jointer for cuts heavier than 1/8 of an inch.  You must press very hard on the work and it could be thrown out causing you to fall into the cutters.

 

8.   You must never change the adjustment of the rear table.  If you think it is out of adjustment, report it to the instructor.

 

9.   Push stock through the jointer slowly.  About 15 feet per minute is the correct feed rate.

 

10.   Stand on the left side of the jointer when using it.  If you stand in back of it, you will have to reach too far forward to push your work through and if the material is kicked out it will hit you.

 

11.   Keep your hands away from the cutter head at all times.  Don’t take any chance of having your hands fall into the cutter head.  Jointers make 10,800 cuts per minute or 180 cuts per second.

 

12.   Whenever cutting tapers on the jointer, make sure you clamp a stop block to the table.  This will support the end of the work and prevent it from kicking back.
