• Removing the rocker switch will lock the unit and
prevent unauthorized use.
A manual reset overload protector is installed in line
with the power supply to the motor. If the planer/molder
is overloaded, the protector will break the circuit.
If the breaker is tripped, turn the planer/molder "off" and
reset the circuit by pressing the button.
Refer to Figures 5- 16.
DESCRIPTION
Sears 12½" planer/molder finishes rough-cut lumber to
size and planes soft and hardwoods up to 5" thick and
121/=" wide. Produces decorative designs includingfur-
niture moldings, baseboards, casings, picture frames,
tongue and groove, glue joints, rabettingand much
more. Wood feeds into three-blade cutterhead by
adjustable rubber in-feed/out-feed rollers. Large 12½" x
19" cast iron table has precision ground steel columns
for smooth feeding of the workpiece and reducing vibra-
tion. Motor has overload protection and is enclosed in
the base of the machine, away from wood chips and
dust. The gearbox offers two speeds; 26 ft/min, for fast
planing, and 13 f!Jminfor smooth finish molding. The
tool comes with anti-kickback mechanism for added
safety, and built-in carrying handles.
OPERATION SAFETY RULES
WARNING: Operation of any power tool can result in
foreign objects being thrown into eyes which can result
in severe eye damage. Always wear safety goggles
complying with United States ANSi Z87.1 (shown on
package) before commencing power tool operation.
CAUTION: Always observe the following safety pre-
cautions:
• Know general power tool safety. Make sure all pre-
cautions are understood (see pages 2, 3 and 5).
• Whenever adjusting or replacing any parts on
planer/molder, turn switch off and remove plug from
power source.
• Make sure all guards are properly attached and
securely fastened.
• Make sure all moving parts are free from interference.
• Always wear eye protection or face shield.
• Make sure Imlves are aligned and propedy attached
to ¢utterhead.
• Do not plug in planer/molder unless switch is in "off"
position.After turning switch on, allow planer/molder
to come to full speed before operating.
• Do not attempt to perform an abnormal or little used
operation without study and the use of adequate jigs,
fixtures and the like.
• Keep hands clear of all moving parts.
• Do not force cut. Slowing or stalling willoverheat
motor. Allow automaticfeed to function properly.
• Use quality lumber. Blades last longer and cuts are
smoother with good quality wood.
• Do not plane material shorter than 14½", narrower
than 3A",wider than 12Y="or thinner than ½".
• Never make planing cut deeper than _,_".
• Maintain the proper relationshipsof infeed and out-
feed table surfaces and cutterhead knife path.
• Do not back the work toward the infeed table.
• Take precautions against kickback.DO not permit
anyone to stand or cross in line of cuttarhead's rota-
tion. Kickback or thrown debris will travel in this
direction.
• Turn switch off and disconnectpower whenever plan-
er/molder is not in use.
• Replace or sharpen knives as they become dam-
aged or dull.
• Keep planer/molder maintained. Followmaintenance
instructions(see page 12).
DEPTH OF CUT
• Thickness planing refers to the sizing Of lumber to a
desired thickness while creating a level surface par-
allel to the opposite side of the board.
• Quality of thicknessplaning depends on the opere-
tor'sjudgement 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 _" for planing operations.For opti-
mum planing performance, the depth of cut should
be less than _,4,-.
• Board should be planed with shallow cuts until the
work has a level side. Once level surlace 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 shallowerwhen work is wider.
• When planing hardwood, take light ct_tsor plane the
wood in thin widths.
• Make test cut when working with a new type of
board or different kind of operation.
• Check accuracy of test cut prior to workingon fin-
ished product.
