WOOD GRAIN
For an improved
surface
finish with minimal tearout,
always plane or mold the workpiece with the grain. The
workpiece should be fed into the planer/molder so that
the
knives 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
dis-
connect it from the power source whenever knife cover
is removed. Never operate planer/molder
without
the
knife 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
13 FPM for an improved
surface
finish or 26 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 was
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 looses contact
with the
board.
•
When planing
more
than
one
board
of
the same
thickness, butt
boards
together
to
avoid snipe.
KNIFE
HEIGHT ADJUSTMENT
Refer to Figures 6 and 15,
pages
7 and 16.
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
knives,
or
per-
forming any adjustment or maintenance to the
planer/molder.
A knife height
gauge
is provided for use when replacing
or
adjusting
the
planing knives
(Key
No. 40).
•
Unplug
the planer/molder
and turn
it OFF.
• Remove the knife
cover
(Key
No.4)
•
Loosen
all
the set screws (Key No.
42)
on all
of the
gibs (Key Nos. 41
and 43) in
all
3
cutterhead
slots.
•
Using the brass
punch,
tap
all
the
gibs
down
into the
cutterhead slot.
•
Make
sure
the
gibs
are
loose and can
be moved.
•
Remove the
old knives, all gibs and spacers (Key
No.
44).
•
Make
sure the cutterhead slots
and gibs
are clean.
• Install the
new planer knives
and replace
gibs
and
spacers.
• Tighten
the
gib
set
screws only enough to
hold the
gibs and knives
in
position.
•
Make sure there is
no
gap
between the g
ibs,
and the
spacers
are
in place.
• Place
the
knife height gauge on
one
end of the knife
and adjust the jack
screw
until
the
knife just
contacts
the tab
in the middle of
the
gauge (see Figure 6).
•
Adjust
both ends of all
three
knives
in
a similar
man-
ner
until all
of
the knives are
at
the same height.
• Tighten the gibs slowly, moving
from
one cutterhead
slot
to the
next,
until
all
three knives
and
all gibs
are
tight and secu
re.
NOTE:
The knives may creep
up
as
the
gibs are
tight-
ened.
Lightly
tap on knives
with a piece
of
hardwood
to
position knives against
jack
screws
if needed.
