2.
Unscrew two knobs (D, Figure 8-3) and remove
deflector cover (E).
Figure 8-3: removing deflector cover
3.
Look through access hole (Figure 8-4), while
lowering head, until you see the hexagonal
recess in center of cutterhead shaft through the
hole. This will be at about the 1-1/4 inch mark
on the thickness scale.
4.
Insert a 4mm hex wrench through hole and into
recess, as shown. Use this wrench to rotate
cutterhead during the knife inspection process.
5.
Use the provided T-wrench to remove two
screws from a knife insert. See Figure 8-4. Lift
knife insert from cutterhead slot.
6.
Rotate knife insert 180-degrees for a fresh edge
and reinstall. Securely tighten screws.
Figure 8-4: knife insert rotation/replacement
Make certain all knife insert
screws are securely tightened before turning on
the planer. Loose inserts can be propelled from
the cutterhead at high speed causing serious
injury.
Remove hex wrench from
access hole before starting planer.
9.0 Operation
Thickness planing refers to the sizing of lumber to a
desired thickness while creating a level surface
parallel to the opposite side of the board.
Note: The cutterhead may throw off a slight spray of
lubricant when the machine is first turned on. Allow
it to run for a few moments, then shut it off and wipe
any oil off the tables before proceeding.
To avoid risk of injury due to
kickbacks, do not stand directly in line with the
front or rear of the planer.
9.1 General recommendations
1.
Many variables determine suitable depth of cut,
such as wood width, density, grain structure,
dampness, etc. For best results, use shallow
cuts and multiple passes. Excessive depth of
cut can place additional strain upon the motor.
2.
Use shallower cuts on wider workpieces.
3.
A thickness planer works best when the lumber
has at least one flat surface. Use a jointer to
create a flat surface. If this is not possible, make
several passes of the same surface through the
planer until it is flat. Then flip the material over
to plane the opposite surface.
4.
Plane alternate sides until desired thickness is
obtained. When half of the total cut has been
taken from each side, the board will have a
uniform moisture content and additional drying
will not cause it to warp.
5.
Make a test cut on scrap wood to verify
thickness; check its accuracy before working on
the finished product.
6.
Avoid knots. Heavily cross-grained wood
makes knots hard. Knots can come loose and
jam the knives.
7.
Do not plane dirty boards; dirt and small stones
are abrasive and will wear out the knife inserts.
8.
Do not plane boards less than 9-1/2 inches
long. It is recommended that when planing short
boards you butt them end-to-end to avoid
kickback and reduce snipe.
9.
For optimum planing performance, the depth of
cut should be less than 1/16-inch.
10. Recommended maximum depth of cut:
Hard/Softwood up to 5-1/2" wide...........1/8"
Hard/Softwood 5-1/2 to 13" wide.........1/16"
9.2 Basic operating procedure
1.
Turn crank handle to desired setting. Use depth
gauge if desired.
2.
Turn on planer and select feed rate.
3.
Turn on dust collection system.
4.
Place material flat-side down on infeed table
and slide it straight into machine until it is
engaged by infeed roller. Do not push or pull on
the workpiece as it is being planed.
5.
Move to rear of planer, out of the line of feed,
and grasp the workpiece as it exits the machine.
