Step 3: Select Feed Direction
Inspect the workpiece and identify the direction of the edge grain. Choose a feed direction such that
workpiece will receive a downhill cut.
Good – Planer Cuts Downhill Not Ideal – Planer Cuts Uphill
Sometimes it is impossible to perform a downhill cut for the entire length of a workpiece. In this case, try
feeding the workpiece in opposite direction and see what works best. Reducing the depth of cut and feed
rate can also help improving cut quality.
Step 4: Planing Wood to Desired Thickness
WARNING
ALWAYS wear goggles, and other protection device when operating this machine.
Stay on the side of the planer next to the power switch to avoid kickback related
accidents. NEVER look inside the planer during operation. Failing to comply may
result in serious injuries or death.
CAUTION
Use ear protection device to prevent hearing loss. Ensure dust collection system is
functional and use dusk mask to avoid inhaling harmful airborne particles.
With the above preparation steps completed, the workpiece is ready for planing.
1. Please put on all protection devices before proceed. If you have a long workpiece, please make sure
it is properly supported throughout the process.
2. Measure the thickness/height of the workpiece, then move the cutterhead no more than 1/16” below
the highest/thickest point of the workpiece. This allows the feed rollers to properly engage the
workpiece, and at the same time not taking too much materials off for a test pass.
3. Turn on dust collection system and the planer.
4. While standing on the side of the planer, place the workpiece on the table with the flat side down.
Gently feed the workpiece towards the infeed roller. Once the infeed roller engages the workpiece,
allow the machine to feed the workpiece. DO NOT force feed the workpiece through the planer.
If the infeed roller does not engage the workpiece:

Headstock height is set too high.

Stop the machine. Wait for the machine to come to a complete stop.
 Raise the headstock and remove the workpiece.

Reduce the initial headstock height, and restart form step 3.
