•
Do not push or 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.
•
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.
Planer
has return
rollers
on top so assistant
can pass work
back to operator
(see
Figure
19).
NOTE:
Assistant
must follow
same precautions
as operator.
•
Surface
that the planer
produces
is smoother
if shallower
depth
of cut is used.

DEPTH
OF
CUT
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.
Board thickness
which
the
planer
will produce
is indicated
by the scale and LCD display.
Preset
the planer
to the desired
thickness
of finished
work-
piece using
knob. See "Workpiece
Thickness
Pre-set
Gauge",
page
7.
Depth-of-cut
is adjusted
by raising
or lowering
the rollercase
using handle.
•
Quality
of thickness
planing
depends
on the operator's
judgement
about
the depth
of cut.
•
Depth
of cut depends
on the width,
hardness,
dampness,
grain
direction
and grain structure
of the wood.
•
Maximum
thickness
of wood which
can be removed
in one
pass is 3/j, for planing
operations
on workpiece
up to 6"
wide.
Workpiece
must be positioned
away from the center
line of the table to cut 313j' due to limit tab in the center
of the rollercase.
•
Maximum
thickness
of wood which
can be removed
in one
pass is _l_r/' for planing
operations
on workpiece
from 6" up
to 13" wide.
•
For optimum
planing
performance,
the depth
of cut should
be less than
_/_6".
•
Board
should
be planed
with shallow
cuts until the work
has a level side. Once a level surface
has been
created,
flip the lumber
and create
parallel
sides.
•
Plane
alternate
sides
until the desired
thickness
is
obtained.
When
half of total depth
of cut is taken from
each side, the board will have a uniform
moisture
content
and additional
drying
will not cause
it to warp.
•
Depth
of cut should
be shallower
when work is wider.
•
When
planing
hardwood,
take light cuts or plane
the wood
in thin widths.
•
Make a test cut with a test piece and verify the thickness
produced.
•
Check
accuracy
of test cut prior to working
on finished
product.
AVOID
DAMAGE
TO BLADES
•
Thickness
planer
is a precision
woodworking
machine
and should
be used on quality
lumber
only.
•
Do not plane
dirty boards;
dirt and small stones
are
abrasive
and wear
out blade.
•
Remove
nails and staples.
Use planer
to cut wood only.
•
Avoid
knots.
Heavily
cross-grained
wood
makes
knots
hard. Knots can come loose
and jam blade.
CAUTION:
Any article
that encounters
planer
blades
may
be forcibly
ejected
from planer
creating
risk of injury.
AVOIDING
SNIPE
•
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
occurs
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 on the lead edge of the workpiece,
adjust
the infeed
table up slightly
above
horizontal.
•
To avoid snipe on the trailing
edge
of the workpiece,
adjust the outfeed
table up slightly
above
horizontal.
•
When
planing
more than one board
of the same
thickness,
butt boards
together
to avoid snipe.
•
Snipe
is more apparent
when
deeper
cuts are taken.
•
Feed work
in direction
of grain. Work
fed against
grain
will have chipped,
splintered
edges.
WARNING:
Be sure planer
is unplugged
from any power
source
and turned
off before
attempting
any maintenance.
CLEAN
PLANER
•
Keep planer
clean of any wood
chips,
dust, dirt or debris.
•
Clean
the four steel columns
to prevent
the roliercase
from
binding
when
raised
and lowered.
•
After
each ten hours
of operation,
clean the chain/gear
drive mechanism.
•
Using
a clean,
dry cloth,
clean all of the chains
and
gears
of wood chips,
dust,
and old grease.
LUBRICATION
•
The table surface
can be coated
with a lubricant,
such
as paste wax,
to make the workpiece
feed smoother.
Be sure
that the lubricant
used does
not affect
the ability
to finish
the workpiece
with varnish,
sealer,
etc.
For example,
do not use any silicone
base lubricants
because
they will ruin any attempt
to finish
the wood.
•
Use common
automotive
bearing
grease
to lubricate
all
chains
and gears.
Be sure all chains
and gears
have
plenty of grease.
•
Motor
and cutterhead
bearings
are sealed
and need
no
lubrication.
