How to Use the Cutterhead Lock
The cutterhead lock Figure 13 helps to eliminate snipe in the
PC4
board that is being planed. Snipe can also be eliminated by
butting boards end to end and feeding them through the planer.
Long boards should ALWAYS be supported, when feeding them
through the planer to help eliminate snipe.
1.
NOTE: To lock the cutterhead, turn handle clockwise.
To unlock, turn handle counterclockwise.
How to Adjust the Head Assembly
The head assembly contains the cutterhead, feed rollers,
chip deflector and motor. Raising and lowering the head
assembly controls the depth of cut.
1.
To adjust the head assembly, unlock the cutterhead lock
handle Figure 13. Turn the cutterhead height
PC4
adjusting handle clockwise to raise or counter-clockwise
to lower the cutterhead. One revolution of handle
Figure 14 will move the cutterhead up or down 1/16 inch
(1.6mm).
How to Use the Material Removal Gauge
See Figure 15
Your planer is equipped with a material removal gauge
used to indicate the amount of wood that will be removed in one
pass with the carriage set at its current height. The material
removal gauge reads across the entire width of the planer head.
1.
Slide approximately 3 inches of the workpiece
the carriage.
2.
Be sure that the workpiece is lying flat against the table
of the planer. If the workpiece is inserted at an angle,
the reading may be inaccurate.
3.
Lower the carriage on the workpiece until the material
removal bar engages the wood. You will see the red
arrow moving up the scale to indicate the amount
A
to be removed with the carriage at that height.
4.
Adjust the carriage height until the desired depth of cut
appears on the gauge.
5.
Note this depth as you may have to back the cutterhead
off the board to allow you to remove it. Once this is
done. Pull the material out from under the carriage and
reset the cutterhead to the desired depth.
6.
Turn the unit on and feed your material into the cutter
head.
