TO CHANGE PLANER KNIVES 1. Use the T-wrench to remove the four screws in the top of the planer. 2. Lift the top off (Fig. 1) and place it aside. 3. Remove the three wing nuts that seal the dust shroud over the cutter head. 4. Rotate the dust shroud up so the round connection that locks onto the fan housing is in the open position (Fig. 2). 5. Push the dust shroud to the left so it disengages from the fan housing. 6. Take the dust shroud out of the unit (Fig. 3) and set it aside. 7. The cutter head is now exposed. If the eight screws in the cutter head clamp are not visible, use a piece of scrap wood to carefully rotate the cutter head (Fig. 4) until the screws are accessible and the cutter head lock lever (R) engages. This will prevent further rotation of the cutter head as you change the knives. WARNING: KEEP YOUR FINGERS AWAY FROM THE CUTTER HEAD AT ALL TIMES. USE THE TOOL PROVIDED TO HANDLE THE KNIVES. 8

If your material is only slightly twisted:
Plane both sides alternating from one to the other until the desired

TO PLANE CUPPED WOOD
To obtain the best possible results with
cupped wood:
Rip the material down the middle and plane it as two separate pieces.
Ripping the material reduces the severity of the cup and allows
the machine to deliver better results. Understand that you will have
to remove more material on cupped wood to achieve the desired
thickness than you would on a normal board.
If ripping the material is not an option:
Plane one side of the material until flat, then plane the opposite side
until it is also flat.
NOTE:
Do not flip the board back and forth between each pass as
recommended by the general planing directions.
TO PLANE BOWED WOOD
The feed rollers and cutter head in your planer will push the bow out
of the material as it feeds. However, when the material exits the
planer, the pressure of the rollers
