The Wood

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.

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.

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

Correct Grain Direction

Feed Direction

Infeed Table

Grain pointing away from the planer

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.

What to Do If a Board Gets Stuck1. 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

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.
