Demonstration

Demonstrate you can safely setup the jointer. You will need to clean up one side and one face of a board. Remember to never adjust the out feed table as it has been precisely set to the height of the cutter head. Adjusting the in-feed table will change the amount of material removed per pass. Do not set the in-feed table to remove more than 1/16" per pass. Your fingers should never go any lower than the height of the cutter guard. Verify the fence is locked and set at the angle needed before making a pass.

Safety

There are several hazards you need to be aware of when using a jointer.

The cutters are very sharp and spin very fast. Keep your fingers away from the cutter head even when its not spinning. Use a push pad/stick to keep your fingers a safe distance from the cutters.
Never let your thumb or fingers hang down near the table when pushing a board through the machine.
Hold onto material firmly and keep it against the table and fence to help prevent material kicking back. If material catches on the blade the material can shoot back at you and this is called a kickback.
Use a hold down or push block when surfacing stock less than 12" long, or 3 inches wide, or 3 inches thick.
Never feed material backwards.
Never try to cut across grain as this could cause a kickback.
Don't exceed 1/16" cut per pass.
