ROLLERCASE LOCK
Refer to Figure 12.
The rollercase can be locked from any movement during
planing in order to guarantee uniform thickness. To lock
rollercase, pull down on lever (A). To release rollercase,
gently push up lever (A)
Figure 12 - Rollercase Lock
NOTE: The rollercase can be raised or lowered when it is
locked by exerting excessive pressure on handle.
However, cranking the handle when the rollercase is
locked will wear down the locking mechanism prematurely.
DEPTH OF CUT
Refer to Figure 13.
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
depth-of-cut-gauge. Preset the planer to the desired thick-
ness of finished workpiece using knob (E). See "Work-
piece Thickness Pre-set Gauge", page 7.
Depth-of-cut is adjusted by raising or lowering the
rollercase (A) using handle (C).
Figure 13 - Depth-Of-Cut
• 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.
F
• 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".
• Maximum thickness of wood which can be removed in
one pass is 1⁄16" for planing operations on workpiece
from 6" up to 13" wide.
• For optimum planing performance, the depth of cut
should be less than 1⁄16".
• 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 will wear out blades.
• 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.
PREPARE WORK
• Thickness planer works best when lumber has at least
one flat surface.
• Use surface planer or jointer to create a flat surface.
• 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.
FEEDING WORK
The planer is supplied with planing blades mounted in the
cutterhead and infeed and outfeed rollers adjusted to the
correct height. Planer feed is automatic; it will vary slightly
depending on type of wood.
• Feed rate refers to rate at which lumber travels through
planer.
• Operator is responsible for aligning work so it will feed
