INTRODUCTION
Spitne Joiner'/iso_e of the strongest methods of joinery usedinwoodworking, When glue isproperly applied to a spline and
to the jointarea of the wood pieces being connected, a large surface area receives the adhesion propertiesof theglue. This
forms a very strong joint.
Traditional spline Joiner'/requires cuttingslots with a muter or table saw. Smafl, thin stripsof wood must then he cut to fit
insidethe slotsand act as splines.
Newer methods of spitne jokiery use aplate or biscuitjoiner to cut precisemating oval slots inadjoining beards. Your new
platejoiner isa fast, simple, and accurate plunge cuttingtoolthat can be usedforthis purpose. If can be used to cutslots in
hardwood, soft wood, plywood,particia board, and otherpressed woods.
Football shap4_l wafers, called biscuits, are then placed Inside the slots with"glue and used to help line up adjoining
surtames.When a water based glue is used, the biscuitsswell in the joint making an extrem*dystrong and firm bond, White
glue,yellow glue. carpenters glue, hide glue, and kiiphatic resin glue are examples of water based glues.
This bonding technique has trediflo_tallybeen limited to makingedge-to-edge joints, However, withthe use of your new
platejoiner, biscuitscan now be easily usedto connectbutt, miter,and T-joints. Biscuitjoining can be as stronglu_mortise
and tenon, tongueand groova, standard8pllne, and doweled joints. In mostcases the material around the biacuit will break
before the biscuitItaeitwill break. A greater Igrtge area Ill8xpoI4rd to glue ina bl_uit joint, rnaidngthe seams stronger.

RULES FOR SAFE OPERATION
READ ALL INSTRUCTIONS
1, KNOW YOUR POWER TOOL -Read owner's
manualcarefully,Learnitsapplications and limi-
tationsas wellas the specificpotentialhazards
relatedto thistool.
2. GUARD AGAINST ELECTRICAL SHOCK BY
PREVENTING BODY CONTACT WITH
GROUNDED SURFACES. For example: Pipes,
radiators,ranges,refrigerator enclosures.
3. KEEP WORK AREA CLEAN. Clutteredareas
and benchesinviteaccidents.
4. AVOID DANGEROUS ENVIRONMENT. Don't
use power tools in damp or wet locationsor
expose to rain. Keep workarea well lit
5. KEEP CHILDREN AND VISITORS AWAY. A{I
visitorsshouldwear safetyglassesand bekepta
safe distancefrom workarea. Do notletvisitors
contacttoolorextensioncord.
6. STORE IDLE TOOLS. When not in use tools
shouldbe storedina dry,highorlocked-upplace
- outof the reach of children.
7. DON'T FORCE TOOL Itwiltdothejobbetterand
saferat the ratefor whichit wasdesigned.
8. USE RIGHT TOOL. Don't force small tool or
attachment to do the job of a heavyduty tool.
Don't use tool for purpose not intended - for
example- Don'tuseacircularsawforcuttingtree
limbsor logs.
9. DRESS PROPERLY. Do notwear looseclothing
orjewelry. They can be caughtin movingparts.
Rubberglovesandnon-skidfootwearare recom-
mendedwhenworkingoutdoors.Also,wearpro-
tactive hair coveringto containlonghairandkeep
itfrom beingdrawn intoair vents.
10. ALWAYS WEAR SAFETY GLASSES WITH
SIDE SHIELDS. Everydayeyeglasseshaveonly
impact resJstsntlenses; they are NOT safety
glasses.
11. PROTECT YOUR LUNGS. Wear a face or dust
mask ifoperationis dusty.
12. PROTECT YOUR HEARING. Wear hearingpro-
taction duringextendedpedods of operation.
13. DON'T ABUSE CORD. Never carry tool by cord
or yank it to disconnect from receptacle. Keep
cord from heat, oil, and sharp edges.
14. SECURE WORK. Use clamps or a vise to hold
work. It's safer than using your hand and it frees
both hands to operate tool.
15, DON'T OVERREACH. Keep proper footing and
balance at all times. Do not use on a ladder or
unstable support
16. MAINTAIN TOOLS WITH CARE. Keep tools
sharp at all times, and clean for best and safest
performance. Follow instructions for lubricating
and changing accessories.
17. DISCONNECTTOOLS. When not in use, before
servicing, orwhen changing attachments, blades,
bits, cutters, etc., all tools should be discon-
nected.
18, REMOVE ADJUSTING KEYS AND
WRENCHES. Form habit of checking to see that
keys and adjusting wrenches are removed from
tool before turning it on.
19. AVOID ACCIDENTAL STARTING. Don't carry
plugged-in tool with finger on switch. Be sure
switch is off when plugging in.
20. MAKE SURE YOUR EXTENSION CORD IS IN
GOOD CONDITION. When using an extension
cord, besure to use one heavy enough to carry the
currentyour product willdraw. An undersized cord
will cause a drop in line voltage resulting in loss of
power and overheating. A wire gage size (A.W.G.)
of at least 16 is recommended for an extension
cord 100 feet or less in length. A cord exceeding
1GOfeet isnot recommended. If in doubt, use the
next heavier gage. The smaller the gage number,
the heavier the cord.
21. OUTDOOR USE EXTENSION CORDS. When
tool is used outdoors, use only extension cords
intended for use outdoors. Outdoor approved
cords are marked with the suffix W-A, for example
- SJTW-A or SJOW-A.
22. KEEP BLADES CLEAN AND SHARP. Sharp
blades minimize stalling and kickback.

OPERATION
A varietyof spllne jointscan be made usingyourplate joiner.
The numberand size biscuitsneeded foreach jointdepends
on the thickness of the wood and the length of the joint, in
general, tbesmall #0 b_cuits ehouM be usedfor mitercuts in
314in.matshels. The larger bizcultsshouldbeusedfor edge-
to-edge jolnery.
When joining 1-1/2 in,thickmaterials,stacktwo biscuits,one
above the other. For example, joining 2 in. x 4 in. dressed
lumber. See Figure 9. When joining even thicker materials,
use eddltional biscuits, stacked above each other.
When makingedge-to_dge jointsfortab_etsps,wortCenches,
cutting boards, etc. the more biacultsyou use, the stronger
the Jointwill be.
The followingsections illustratehow to make vadous spline
jointsuelog yourplate joiner.
EDGE-TO-EDGE JOINTS
See Figures 7 and 8.
Edge-to-edge joine_J is one of the most basic and easiest
jointstoconstruct. Ingeneral, two basicadjustments have to

OPERATION
BUTT JOINTS
See Figure 9.
A butt joint is one of the weakest joints in woodworking.
This type of joint is mating the end grain of one board with
the edge grain of another. The Pendingof glee on thistype
of surface Is poor. However, by using biscuits you can
create a very strong joint that gives a modise-and-tonon
effect.
HOW TO MAKE BUT[ JOINTS
1. Unplug your plate joiner.
2. Place the two pieces of wood to be joined on a level
workbench. Align them against each other in the ar-
rangement inwhich they will be assembled,
3. Using a square, determine the location of each biscuit
sptine Jointand mark the center of each joint bydrawing
aline across the edges of the two boards.
4. Loosen heightadjustment knobs and set fence angle at
g0°.
5. Slide the fence up or down until the indicator point is
aligned with the desired dimension on the scale, RE-
MEMBER: The scale indicatesthe heightof the fence
from the center of the blede,
6. Tighten heightadjustment knobs securely,
7. Select thecorrect depthof cutsettingto matobthe biscuit
size you are planningto use. We suggestthat you make
atest cut in a scrap piece of wood from the same
work_ece if possible.
8. Clamp workpiece securelyso thatif will not move duhng

OPERATION
T-JOINTS
See Figures 11-15.
A T-jolot is used when the end of a board is joined to the
face of another board as shown in figure 11. Attaching
shelves to bookcases and inner support braces to frames
are typical applications, Actual cutting of a T-jofnt is as
slmpla as any other cut. However, itis cdtlcetthat you mark
the centedloes, mark the intersection points for each slot,
and cut each slot correctly.
HOW TO MAKE T-JOINTS
1. Unplug your plate Joiner.
2. Piece the two places of wood to he joined on a level

3. Determine the locationof each biscuitjointand mark the
centedloeson each board as shown. The centedines for
both boards must line-up with each other. Measure
carefully, these measurements must he accurate and
precise. TIP: Measure twice and cut once, in addition
to thecentedinaslining up,the spacingofthe biscuitslots
from side-to-side must also match.
4. Plugyour plate joiner intopower supplyand cut slotsin

GENERAL
Only the parts shown on pads list, page twenty three, ere
intended to be repaired or replaced by the customer. All
otherparts representan important part of the double insuia-
tion system and should be serviced only by a qualified
Sears service technician at an authorized service facility,
Avoid using solvents when cleaning plastic parts. Most
plastic_=are susceptible to vadous types of commercial sot-
vents and may be damaged by their use. Use clean cloths
to remove dirt,dust, oil, grease, etc.
When electrictoolsare used on fiberglassit has beenfound
that they are subject to accelerated wear and possible
premature failure, as the fiberglass chips and gtindingsare
highly abrasive to hearings, brushes, commutator, etc,
Consequently it is not recommended that this tool be used
for extended work on any fiberglass material, During any
use on fiberglass it is extremely important that the tool is
cleaned frequentlyby blowing withan air jet.
