WOOD GRAIN
For an improved surface finish with minimal tear out,
always plane or mold the workpiece with the grain. The
workpiece should be fed into the planer/molder so that
the blades or bits are traveling with the grain as the cut-
ters finish the cut. The grain should be angled up
toward the rear of the workpiece as it is fed into the
planer/molder.
PLANING
WARNING:
Always turn the planer/molder off and
disconnect it from the power source whenever blade
cover is removed. Never operate planer/molder without
the blade cover properly secured.
The planer/molder is supplied with planing blades mount-
ed in the cutterhead and the infeed and outfeed rollers
adjusted to the correct height. The planer/molder is capa-
ble of working at two different feed rates. Feed rate refers
to rate at which lumber travels through planer/molder.
Planing can be done at 10 FPM for an improved surface
finish or 20 FPM for faster planing (see Feed Rate
Adjustment).
Adjust the table height to produce the depth of cut
desired.
Stand to side which the handwheel is attached.
Lift edge to infeed side of the table by grasping
edges of board at approximately
middle of length.
Boards longer than 24" should have additional sup-
port from free standing material stands.
Position the workpiece with the face to be planed on
top.
Gently slide the workpiece into the infeed side of the
planer/molder until the infeed roller begins to
advance the workpiece.
Let go of the workpiece and allow automatic feed to
advance the workpiece.
Do not push/pull on workpiece.
Move to the rear and receive planed lumber by
grasping it in same manner as it was fed.
CAUTION:
Do not stand directly in line with front or
rear of planer/molder.
Do not grasp any portion of board which has not
gone past out-feed roller.
Repeat this operation on all boards which need to be
same thickness.
AVOIDING
SNIPE
Surface that the planer/molder will produce will be
smoother if shallower depth of cut is used. Snipe refers
to a depression at either end of board caused by an
uneven force on cutterhead when work is entering or
leaving planer. Snipe will occur when boards are not
supported properly or when only one feed roller is in
contact with work at beginning or end of cut. To avoid
snipe:
Gently push the board up while feeding the work
until the outfeed roller starts advancing it.
Move to the rear and receive planed board by gently
pushing it up when the infeed roller loses contact
with the board.
When planing more than one board of the same
thickness, butt boards together to avoid snipe.

HEIGHT
ADJUSTMENT
Refer to Figures 10-14 and 28, pages 7, 8 and 18.
WARNING:
Disconnect planer/molder from the power
source and turn the planer/molder OFF before attempt-
ing to adjust or replace the cutting bits or blades, or per-
forming any adjustment or maintenance to the
planer/molder.
A blade height gauge is provided for use when replac-
ing or adjusting the planing blades (Key No. 2).
Unplug the planer/molder and turn it OFE
Remove the blade cover (Key No. 8)
Loosen all the set screws (Key No. 41) on all of the
gibs (Key Nos. 40 and 42) in all 3 cutterhead slots.
Figure 10 - Loosen all Gib Set Screws
Using the brass punch, tap all the gibs down into the
cutterhead slot.
Make sure the gibs are loose and can be moved.
