Additional Tips for Jointer safety:

get someone to help you with full length boards. Be sure they are following safety rules for the joiner also

Push forward NOT down against blades as they cut- LET THE BLADES DO THE WORK FOR YOU

Do not talk to anyone while jointing or let anyone within the machine’s safety zone while using the machine

Have a plan for your cut before you turn the machine on
