10. Personal Safety Preparation
Always wear safety glasses when operating any
machine.
Remove exposed keys or cell phones and any other
items that could get caught in the machine.
Tape measures should also be removed.
Always tuck the front half of your shirt while
operating the jointer.
15. 8” Cutter Head
Cutter Head rotates clockwise when looking at it
from the front of the machine.
This means that it is rotating towards the Infeed
Table.
16. Margin of Safety
Margin of Safety 12” total
Margin of Safety 6” on each
side of the Cutter Head.

18. Body Position
People should never be directly behind or in front of
the Ends of a board.
This includes the operator or anyone else in the shop.
This applies to the Infeed and Outfeed table.
This rule is in place to avoid possible injury to
anyone due to Kickback.
It is the operators responsibility to make sure this
area is clear.
19. More Safety Considerations
Always use a Metal Detector to check wood
for metal that could be inside and not visible.
Make sure the Guard is operating properly by
pulling the Guard back slightly and allowing
it to snap back towards the Fence.
Check the Guard only when the Cutter Head
is not moving. Do not use and tell instructor
immediately if the Guard is not working
properly.
20. Reasons Why the Jointer is Dangerous
The Cutter Head runs at a very high RPM.
The Cutter Head blades are extremely sharp.
The Cutter Head is exposed as the board is
exiting.
21. Fence Lock
Always make sure
that the Fence
Lock is locked by
making sure it is
just snug.
22. The 2 Adjustments an Operator Can Make
The student can loosen and tighten the Fence
Lock in order to move the Fence into the
correct position
The Infeed Table Height Adjustment can be
moved by an operator. But, in our class the
students will never adjust the Infeed Table
height.
Only the instructor will ever adjust the Infeed
Table.

24. Face Jointing- Fence Adjustment
Move the Fence up far enough to cover extra
Cutter Head but wide enough to allow your
board to pass through.
Always run your board through with the
machine off (Dry Run) so that you know that
your board will make it through.
This is important because your board may be
wider at one end.
26. Other Face Defect Issues
Always joint the Bowed Face
Always get instructor assistance when trying
to joint a Twisted board
When these rules conflict each other, use the
most stable Face.
Stable means that the board should not rock
or shift while cutting.
27. Face Jointing- Hand Placement
Make sure all Push Blocks that your intend on using during
your cut are within easy reach.
Your left hand (leading hand) will start with a Push Blocks in
contact with the top of the board a few inches back from the
End.
When jointing the Face of a longer board you must use your
right hand to feed the wood.
When your board reaches the end of the Infeed Table, you
will pick up your Combo Block, hook it on the End of the
board, and use it during the rest of the cut.
When picking up the second Push Stick, make sure that your
left hand and Push Block are not moving and are not inside
of the Margin of Safety.
28. Face Jointing Short Boards- Hand
Placement
The operator can start with a Combo Block in the
right hand, and hooked on the End of the board.
If the board is long enough, you can use a Push
Block in the left hand to help guide the wood.
If the board is very short (minimum 12”), only use
the Combo Block. You must use both hands on the
combo block handle.
Always use a Combo Block and Push Block when
moving your hands through the Margin of Safety.
Never have your hands in contact with the board
while moving through the Margin of Safety.

30. Edge Jointing
This is the 3rd step in the 6 step process
Make sure to loosen the Fence Lock Handle
and bring the Fence as far forward as possible
to reduce the amount of exposed Cutter
Head.
Make sure that the Fence is relocked before
continuing.
Then make a Dry Run while the machine is
off.
31. Edge Jointing with Defects
Crook Down, wood is stable Crown Down, wood not stable
CORRECT INCORRECT
Flip 180 deg. to correct.
32. Hand Placement
A Push Stick and Push Block need to be used
on any board that is not wider than 6 inches.
If the board is wider than 6 inches, then the
operator can use their hands to feed the board
through.
All parts of your hands must remain above the
Fence even when jointing a wide board.
33. Body Placement
Always stand in an upright position, never
lunge or lean.
Use small shuffled steps and move with the
wood as you joint it.
Always use consistent and smooth pressure.
Keep your arms straight and your body close
to the machine. This allows you to use your
body weight to help feed the board.

36. General Machine Rules
Tuck in you shirt.
Make sure machine reaches Full RPM, The
noise stops changing.
Make sure that the Cutter Head stops moving
before leaving the machine.
Clean up area: push tools, tools, and pieces of
wood.
37. Jointer Wrap-Up
Jointing makes the surface flat.
Jointing improves a Rough Sawn finish.
38. Jointer Wrap-Up
Step 2 (Jointing the cupped face) and Step 3
(Jointing the crooked edge) create a Square
corner along the length of the board.
