3. Purpose of the Planer
Surface the second face
Second face should be the crowned face
Outcomes
Uniform thickness over the entire length and
width of the board.
This means that the faces are parallel.

15. Indexing the Planer
Check for debris before indexing.
Place the thickest part of the board under the cutting
head.
Raise table until the board is just barley snug.
Lower table by turning Table Height Adjustment
Wheel 1 full turn counter clockwise.
Remove board.
Raise the Table Height Adjustment Wheel 1 ½ turns
clockwise.
18. Hand Position
Placing your fingers
under the board could
cause them to get
smashed
Fingers should always be
kept on the sides or
edges of the wood.
19. Outfeed Position
The operator must
support the wood
as it leaves the
machine.
Never pull on the
wood or reach in
to the machine.
20. Three things you can touch
On/Off swich
Table Height Adjustment
The Wood
21. Table Height Adjustment
You can adjust the table height while the
machine is running.
Never adjust the height while the wood is in
the machine.
22. Margin of Safety
Any other part of the machine other than the
previously listed parts.
This includes the infeed and outfeed tables
and any other parts of adjustments not
specifically listed in the previous slide.
23.
24. Snipe
Snipe can happen at either end of a piece of wood up to 6”
from the end, when the wood flexes up and the cutter makes a
deeper cut than desired.
Snipe is caused by the wood not being in contact with the out
feed rollers on its way into the machine.
On the out feed, it happens when the wood comes out of
contact with the infeed rollers
26. Defects
Surface tear out means that you are planing against
the grain.
Grain direction can be difficult to judge. Trial and
error is the best method. Flip the board lengthwise to
change the grain direction.
Ridges running the length of the board are a sign of
chipped teeth.
Tell the instructor if you find ridges in you wood.
27. What to Do If a Board Gets Stuck
1. Use a trailer board that has the
same or smaller thickness than
the board you are planing.
2. If the wood is still stuck after step #1 using light
pressure, shut off the machine and wait untill it comes
to a complete stop. Remove your board and re-index
the planer.
3. Get the instructor to help
28. Clearing Debris Stuck Inside
First, use a long piece of wood to try to push the
debris out
If it is still stuck, inform the instructor
The instructor will make sure that the power and the
circuit breaker are disconnected and turned off.
Even though the power is off the blades can still cut
you if you bump into them, so make sure to lower
the table far enough to ensure safe clearance.
