DESCRIPTION
Craftsman 41/8'' jointer/planer is used to surface the faces
and edges of boards, produce a flat surface on warped
boards and shape bevels, chamfers and tapers. The joint-
er/planer features cast aluminum infeed and outfeed
tables, lightweight plastic body with smooth work sur-
faces and leadscrews for precise table height adjustment.
Balanced guide fence tilts 45° (inward) and 45° (outward).
Tool comes with locking rocker switch with removable key
and push blocks. Jointer/planer easily handles rough-cut
lumber, planes hard and soft woods up to 41/8'' wide using
a two blade cutterhead, and takes cuts up to 1/8".
OPERATION SAFETY RULES
Jointing is a surfacing operation in which a small
amount of wood is removed from the edges and faces of
boards to get smooth, straight and even surfaces such
that the two edges that run across the planing blocks
would fit together perfectly, forming a seamless joint.
Planing refers to the sizing of lumber to a desired thick-
ness while creating a level surface parallel to the oppo-
site size of the board. Depth of cut is the term used to
indicate how deep the blades will cut into the workpiece.
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.
WARNING: For your own safety, read all of the
instructions and safety precautions before operating
tool.
• Know general power tool safety. Make sure all pre-
cautions are understood (see pages 2, 3, 5 and 6).
° Whenever adjusting or replacing any parts on
jointer/planer, 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 blades are aligned and properly attached
to cutterhead.
° Do not plug in jointer/planer unless switch is in "off"
position. After turning switch on, allow jointer/planer
to come to full speed before operating.
• Keep hands clear of all moving parts.
• Do not force cut. Slowing or stalling will overheat
motor.
• Use quality lumber. Blades last longer and cuts are
smoother with good quality wood.
• Do not perform jointing/planing operations on materi-
al shorter than 6W', narrower than 3/4",or less than
1/4"thick
° Never make jointing cut deeper than W'.
• Always keep cutterhead and blade guards in proper
working condition.
• Maintain the proper relationships of infeed and out-
feed table surfaces and cutterhead blade path.
• Do not back the work toward the infeed table.
• Support the workpiece adequately at all times during
operation; maintain control of the workpiece.
° Use hold-down/push blocks for jointing material nar-
rower than 3" or planing material thinner than 3".
• Take precautions against kickback. Do not permit any-
one to stand or cross in line of cutterhead's rotation.
Kickback or thrown debris will travel in this direction.
• Turn switch off and disconnect power whenever
jointer/planer is not in use.

. Replace or sharpen blades as they become damaged
or dull.
o Do not attempt to perform an abnormal or little used
operation without study and the use of adequate hold-
down/push blocks, jigs, fixtures, stops and the like.
° Keep jointer/planer maintained. Follow maintenance
instructions (see pages 9-10).
DEPTH OF CUT
Refer to Figure 7.
The depth of cut is adjusted by the relative positioning
of the infeed table with respect to the cutterhead. Infeed
table can be raised or lowered using the handwheel.
Turning the handwheel counterclockwise will lower the
infeed table causing more wood to be removed from
workpiece. Turning the handwheel clockwise will raise
the infeed table causing less wood to be removed from
workpiece.
Do not make jointing or planing cuts deeper than 1/8".
Infeed Table
POSITIONING FENCE
Refer to Figure 9.
The fence can be adjusted to cut various angles from
0o-45° inward and outward. The fence can be tilted
inward up to 45 ° (toward the cutterhead) to maintain
greater stability of a narrow workpiece or up to 45° out-
ward (away from cutterhead) for larger angle cutting
operations.
To adjust fence position:
. Loosen fence lock knobs from both sides of the fence.
. The angle setting is marked on the left fence seg-
ment piece.
. The right fence segment has a positive stop pin to
stop fence at 45 ° inward, 0° (90° to table) and at 45°
outward.
. To tilt fence, gently lift the pin and the fence can be
tilted to any desired angle within the range.
. To lock fence, release the pin and tighten the fence
lock knobs.

BLADE GUARD
The blade guard provides protection over the cutter-
head. It must always be in place and function properly.
Check the guard to make sure it functions properly. To
check:
. Pass a 1/4"thick piece of wood over the cutterhead
between the guard and the fence. The guard will
spread and leave way for the wood piece to pass.
The guard must return to the original position auto-
matically when the wood piece is removed.
. Open the blade guard all the way until it stops, and
release it several times. It should always return to its
original position by spring action.
CAUTION: If the blade guard fails to operate properly,
the spring must be replaced or adjusted.
. To replace spring, contact your nearest Sears store
or service center.
° To adjust or to assemble spring see "Adjusting Blade
Guard", page 9.

ADJUSTING BLADE HEIGHT
Refer to Figures 10 and 11.
CAUTION: Make sure the switch is in the "OFF" posi-
tion and cord is unplugged before proceeding with
checking blades.
The blades have been adjusted at the factory to assure
proper operation and should require no adjustment.
However, shipping and handling may have caused mis-
alignment. For accurate cutting, the blades must be
0.003" higher than the outfeed table when positioned at
the highest point. To check blade height:
• Block the blade guard from closing using a scrap
piece of wood about 4-1/," long between the fence
and blade guard.

• Turn the cutterhead so that one of the blades is at
the highest position.
CAUTION: The cutterhead blades are extremely
sharp. Do not let your fingers contact the cutting edge
at any time.
• Place a straightedge over the outfeed table and the
blade.
Back Side of Machine
AVOID DAMAGE TO BLADES
Jointer/planer is a precision woodworking machine and
should only be used on quality lumber. Using bad lumber
could result in a poor quality cut on subsequent pieces.
For proper operation, it is preferable to use the jointer with
a dust collecting system (see "Using a Vacuum Hose",
page 8) attached to the exhaust port in the rear of the
jointer. Attaching a dust collecting system is especially
required when taking deeper cuts to prevent clogging of
wood chips.
• Do not use dirty boards. Dirt and stones are abrasive
and will wear blade.
• Remove nails and staples. Jointer should only cut wood.
• Avoid knots. Heavy cross-grain makes knots hard
and they can come loose and jam the jointer.
• Assess value of badly warped boards. Operator can
be tempted to use too deep of cut to square boards
quickly. Use several passes to maintain a level surface.
ON-OFF SWITCH
Refer to Figure 12.
The operating positions of the "On-Off" switch are locat-
ed on the front of your jointer/planer.
• Push the switch up to turn jointer/planer On and
push down to turn the unit Off.
• The switch has a removable key that allows the unit
to be locked in the "Off" position.
To activate locking mechanism:
• Push the switch to "Off" position.
• Pull switch key.
To deactivate locking mechanism:
• Insert and press switch key in the slot on switch.
Straightedge,
Outfeed Table
Figure 11 - Adjust Blade Height
• The straight edge must touch evenly on the outfeed
table at both ends of the blade.
• Turn the cutterhead slowly, and check if the blade
lightly touches the straight edge.
• If the straightedge raises, loosen the blade lock
screws and gently tap the blade with a piece of
scrap wood. If the blade does not touch the straight-
edge, loosen the blade lock screws and raise the
blade by prying the lower edge of the blade against
the outfeed table using a screwdriver.
• Tighten blade lock screws.

FEEDING WORKPIECE
Refer to Figures 13, 14, 15 and 16, page 8.
Feed rate refers to rate at which wood is passed over
blades. An even feed will produce a uniform service. To
feed workpiece:
• Hold the board firmly down on both tables and
against the fence.
• Keep fingers close together.

![](/html/2a/2a73/2a73ca48602f5cdcb6f5eb754aaa190d140805dcd4fd181539335a8dd01c9924/bg8.png)
Feed the board at a continuous even rate of speed.
Any hesitation or stopping could cause a "step" to be
cut on the edge of the board.
Figure 13 - FeedingWorkpiece
• As the trailing hand passes over the cutterhead,
remove the leading hand.
• Continue feeding while placing the leading hand
behind the trailing hand until the entire length of the
board is cut.
Figure 14 - Guiding Workpiece
• Feed with the grain whenever possible.
Rotation
Figure 16- Feeding with Push Blocks
• Grasp the hold-down/push-blocks firmly.
• Position the push-blocks flat on top of workpiece and
push the workpiece down against the table.
• Use a hand-over-hand motion to maintain control
over the workpiece at all times.
• When planing workpiece between 1__3/4,,and nar-
rower than the push-blocks, tilt the push-blocks so
that it clears the cutterhead guard while feeding.
BEVELING AND CHAMFERING
Refer to Figure 17.
• The fence on the jointer/planer is adjustable from
45° inward to 45° outward. Adjust the fence to the
desired angle and tighten fence lock knobs. You may
require to lift the positive pin to move fence.
• Beveling refers to cutting the entire edge of a board
at an angle. Bevelling may require several passes
due to the depth of cut needed.
• Chamfering refers to removing only the corner of the
edge of a board. Normally a chamfer is made on one
pass; so a _/_6"depth of cut is made.
Bevel Edge
_n
Rotation
Figure 15 - Direction of Feed
• Ifthe nature of the workpiece is such that it must be fed
against the grain, take very light cuts and feed slowly.
• When using long workpieces, to avoid injury from slips
or kickbacks and to exert even pressure on the cutter-
head, use extra supports (see Recommended
Accessories, page 13) at both infeed and outfeed ends.
USING HOLD DOWN/PUSH BLOCKS
Refer to Figure 16.
• Always use hold-down/push-blocks when jointing, or
rabbeting wood that is narrower than 3", planing
wood thinner than 3".
Chamfer Edge
Figure 17 - Beveling and Chamfering
USING A VACUUM HOSE
A standard dust collection hose can be attached to the
exhaust port (2 _/2"Dia.) on the rear of the jointer. Jointer
will perform properly at all depths of cuts up to _/8"when
used with a dust collecting system. (See "Avoid Damage
to Blades", page 7.) To attach a dust collecting system:
• Insert the dust collection hose to the exhaust port on
the rear of the jointer.
• Turn the dust collecting system on.
• Turn the jointer on.
• Periodically replace/empty bag in the dust collecting
system.
