Safety Switch
WARNING

Always make sure the switch is in the off
position before plugging in the planer!
Failure to comply may cause serious injury!
To remove the safety switch, first turn off the
planer. Pull out the switch key (A, Fig. 6), and
store in a safe place. Re-install the switch key
just before operating the planer.
Setting the Depth of Cut
CAUTION

Never turn the thickness adjustment handle
while stock is being planed. This can put
stress on the blades, the cutterhead, and the
motor which can lead to machine damage.
1. One side of the material should be run
through a jointer before planing.
2. Turn off the planer.
3. Place the material with the flat side down on
the planer bed. Slide the material under the
infeed roller and lower the head until the
gauge (A, Fig. 7) shows 1/64".
4. Run the material through the planer at this
setting to start.
5. One full clockwise revolution of the handle
assembly (B, Fig. 6) will lower the depth of
cut approximately 5/64".
6. First cuts should be very shallow. You may
wish to make several passes shallower than
5/64".
Planing Warped Wood
WARNING

Do not attempt to plane a board which is
warped along its length. A warped board
can jam itself against the cutterhead knives
resulting in kickback and or damage to the
planer.
Failure to comply may cause serious injury!
For best results one side of the material should
be run through a jointer prior to planning.
However, if a board is somewhat cupped, as in
Figure 8, you may attempt to plane it. If the
board is narrow enough, consider using a
tablesaw or bandsaw to rip the top of the warp
before planing the board. If this is not practical,
plane the top of the board until it is flush with
the two sides of the board.
Turn the board over and plane the bottom edges
until they are flush with the middle.
planing the board, use a tablesaw or jointer to
square the board's edges.
