PREPARE WORK AREA FOR JOB

• Keep work area clean. Cluttered work areas invite
accidents.

• Do not use power tools in dangerous env ironments.
Do not use power tools

in

damp

or

wet locations. Do

not expose power tools to rain.

• Work area should be properly lighted.

• Proper electrical receptacle should be available for
tool. Three prong plug should be plugged directly
into properly grounded, three-prong receptacle.

• Extension cords should have a grounding prong and
the three wires

of

the extension cord should be of

the correct gauge.

• Keep visitors at a safe distance from work area.

• Keep children out of workplace. Make workshop child­proof. Use padlocks, master switches or remove switch
keys

DESCRIPTION

Sears 12W' planer/molder finishes rough-cut lumber to
size and planes soft and hardwoods up to

5" thick and
12W' wide. Produces decorative designs including fur­niture moldings, baseboards, casings, picture frames,
tongue and groove, glue joints, rabetting and much
more. Wood feeds into three-blade cutterhead by
adjustable rubber in-feed/out-feed rollers. Large

12W' x
19" cast iron table has precision ground steel columns
for smooth feeding of the workpiece and reducing vibra­tion. 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

ftlmin. for fast

planing, and

13ft/min

for smooth finish molding. The
tool comes with anti-kickback mechanism for added
safety, and

bu

ilt-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 knives are aligned and properly attached
to cutterhead.

5

• Do not plug in planer/molder unless switch is in "o ff"
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 will overheat
motor.

Allow automatic feed to function properly.

• Use quality lumber. Blades last longer and cuts are
smoother with good quality wood.

• Do not plane material shorter than

14Y2'',

narrower

than

3

.4"

, wider than 12W'

or

thinner than W'.

• Never make planing cut deeper than % ".

•

Maintain the proper relationships of infeed and out­feed 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 cutterhead's rota-

tion . Kickback

or

thrown debris will travel in this

direction.

• Turn switch off and disconnect power whenever plan­er/molder is not

in

use.

• Replace

or

sharpen knives as they become dam-

aged

or

dull.

•

Keep planer/molder maintained. Follow maintenance
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

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

%2''

for planing operations . 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 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 test cut when working with a new type

of

board or different kind

of

operation.

• Check accuracy of test cut prior to working

on

fin-

ished product.
