Thickness Scale
WORKPIECE THICKNESS PRESET GAUGE
Refer to Figure 15.
A six position workpiece thickness pre-set control knob is
mounted on the right side of the planer. This feature allows
quick production of identically sized workpieces. Six settings
are provided: %", W', _/2",3/4%1" and 1W'. See "Maintenance"
section to calibrate thickness preset gauge.
Figure 13 - Raising or Loweringthe Rollercase.
Counterclockwise Down/Clockwise Up
FEED RATE ADJUSTMENT
Refer to Figure 14.
• The planer has a 2-speed gearbox that feeds the work-
piece at 22 feet per minute (standard planing) and at
11 feet per minute (finish planing).
Finish planing a workpiece results in a better surface finish
than that obtained by planing at the higher speed.
• The knob for adjusting the feed rate is located on the left
side of the top of the rollercase.
NOTE: Only change feed rate while the machine is running.
DEPTH-OF-CUT GAUGE AND SCALE
Refer to Figure 14.
A depth-of-cut gauge is attached to the front of the rollercase.
The pointer on the depth-of-cut gauge accurately displays the
depth-of-cut per pass when workpiece is positioned below the
gauge. Cranking the handle moves the rollercase down and
the pointer shows depth-of-cut up to 3/32".
Recommended Maximum Depth-Of-Cut:
Hard/Softwood up to 6" wide: ...................... 3/32"
Hard/Softwood 6" to 13" wide: ..................... _/,_"
The Thickness scale with pointer allows easy adjustment of
roller case height. This scale indicates the finished size of the
workpiece in inches and millimeters. The side pointer can
be adjusted by loosening the pointer screws, re-positioning
pointer and retightening pointer screws.
Thickness Preset Gauge
Figure 15 -Thickness Preset Gauge
Example: Plane a 2" thick workpiece down to 1'/4".
° Raise or lower rollercase until it is just above the
workpiece.
° Position the workpiece on the planer table below the
rollercase.
° Rotate knob until 1W' is indicated.
° The planer is now set to stop the rollercase when the
workpiece thickness reaches 1W'.
NOTE: To reset for a different depth stop, raise the rollercase
by about 2 rotations. Turn knob to desired setup.
DIGITAL DISPLAY PANEL
Refer to Figure 16, page 8.
° The digital display panel consists of two LCD displays
and four control buttons.
° Display "A" shows the absolute height of the rollercase
over the table, which is also the finished workpiece
thickness.
° Display "B" shows the depth of cut on the workpiece.
° Button 'A' is used to calibrate display 'A'.
° Button 'B' is used to reset display 'B' to zero (0).
° Button 'C' toggles both displays A and B between inches
and millimeters.
° Button 'D' turns power On and Off to display 'A' and 'B'.

Figure 16 - Digital Display Panel
CALIBRATING AND USINGTHE DIGITAL DISPLAY
To calibrate the display "A":
• Set the preset depth control knob at 1" (see Figure 15,
page 7).
• Plane a piece of scrap wood to 1". Check wood thickness
with caliper to ensure wood thickness, preset stop and dig-
ital display match. If the wood thickness and preset stop
do not correspond, calibrate the preset stop prior to cali-
brating the digital display. See "Maintenance", page 12.
• Remove button 'A', and using a punch or other suitable
object, insert into the button hole and press. The display
A will read 1.0000" or 25.4 mm. (see Figure 17).
To use depth of cut display "B":
• Feed workpiece through planer, taking a shallow cut.
Depress button 'B', which will set display B to zero (0).
• Lower rollercase until desired depth of cut is shown on
display "B".
• Feed workpiece and repeat.
° Twisted or severely warped boards can jam planer. Rip
lumber in half to reduce magnitude of warp.
° Work should be fed into planer in same direction as the
grain of the wood. Sometimes grain will change directions
in middle of board. In such cases, if possible, cut board
in middle before planing so grain direction is correct.
CAUTION: Do not plane board which is less than 15" long;
force of cut could split board and cause kickback.
PLANING
WARNING: Always turn the planer off and disconnect it from
the power source whenever blade cover is removed. Never
operate planer without the blade cover properly secured.
The planer is supplied with planing blades mounted in the
cutterhead and the infeed and outfeed rollers adjusted to the
correct height. The planer is capable of working at two differ-
ent feed rates. Feed rate refers to rate at which lumber travels
through planer. Planing can be done at 22 FPM (standard
planing) or at 11 FPM for an improved surface finish (see
Feed Rate Adjustment).
° Position rollercase to produce the depth of cut desired.
° Operator is responsible for aligning work so it will feed
properly.
° 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 support
from free standing material stands.
° Position the workpiece with the face to be planed on top.
° Turn the planer on.
° Rest board end on infeed table and direct board into planer.
° Gently slide the workpiece into the infeed side of the planer
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 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 18).
Figure 17 - Calibrating the LCD Display
PREPARE WORK
* Thickness planer works best when lumber has at least
one flat surface.
* Use surface planer or jointer to create a flat surface.
Figure 18 -Workpiece on the Return Rollers
8
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 3/32"for planing operations on workpiece up to 6"
wide. Workpiece must be positioned away from the center
line of the table to cut 3/32"due to limit tab in the center
of the rollercase.
• Maximum thickness of wood which can be removed in one
pass is _/_6"for planing operations on workpiece from 6" up
to 13" wide.
• For optimum planing performance, the depth of cut should
be less than V_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 rollercase
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.
CHECK FOR WORN BLADES
• Condition of blades affects precision of cut. Observe quality
of cut which planer produces to check condition of blades.
• Dull blades tear, rather than sever wood fibers and
produce fuzzy appearance.
• Raised grain occurs when dull blades pound on wood that
has varying density. Raised edge will also be produced
where blades have been nicked.

of rollercase with base:
° Using a test piece, measure height of the taper. Determine
which corner or side needs adjustment.
° Turn planer off and disconnect from power source.
° Fold front and rear extension tables.
° Lay planer carefully on its back so that bottom side of
base is facing you.
° Loosen two socket head bolts on the idler bracket. Loosen
chain by sliding idler bracket.
