SECTION 1: SAFETY

For Your Own Safety, Read Instruction

Manual Before Operating This Machine

The purpose of safety symbols is to attract your attention to possible hazardous conditions.

This manual uses a series of symbols and signal words intended to convey the level of impor­tance of the safety messages. The progression of symbols is described below. Remember that
safety messages by themselves do not eliminate danger and are not a substitute for proper
accident prevention measures. Always use common sense and good judgment.

Indicates an imminently hazardous situation which, if not avoided,
WILL result in death or serious injury.

Indicates a potentially hazardous situation which, if not avoided,
COULD result in death or serious injury.

Indicates a potentially hazardous situation which, if not avoided,
MAY result in minor or moderate injury. It may also be used to alert
against unsafe practices.

This symbol is used to alert the user to useful information about

NOTICE

proper operation of the machine.

Safety Instructions for Machinery

OWNER’S MANUAL. Read and understand this

owner’s manual BEFORE using machine.

TRAINED OPERATORS ONLY. Untrained oper­ators have a higher risk of being hurt or killed.
Only allow trained/supervised people to use this
machine. When machine is not being used, dis­connect power, remove switch keys, or lock-out
machine to prevent unauthorized use—especially
around children. Make workshop kid proof!

DANGEROUS ENVIRONMENTS. Do not use
machinery in areas that are wet, cluttered, or have
poor lighting. Operating machinery in these areas
greatly increases the risk of accidents and injury.

MENTAL ALERTNESS REQUIRED. Full mental
alertness is required for safe operation of machin­ery. Never operate under the influence of drugs or
alcohol, when tired, or when distracted.

ELECTRICAL EQUIPMENT INJURY RISKS. You
can be shocked, burned, or killed by touching live
electrical components or improperly grounded
machinery. To reduce this risk, only allow qualified
service personnel to do electrical installation or
repair work, and always disconnect power before
accessing or exposing electrical equipment.

DISCONNECT POWER FIRST.
nect machine from power supply BEFORE making
adjustments, changing tooling, or servicing machine.
This prevents an injury risk from unintended startup
or contact with live electrical components.

EYE PROTECTION. Always wear ANSI-approved
safety glasses or a face shield when operating or
observing machinery to reduce the risk of eye
injury or blindness from flying particles. Everyday
eyeglasses are NOT approved safety glasses.

Always discon-

-10 -

Model G0490W/G0490XW (Mfd. Since 5/16)

WEARING PROPER APPAREL. Do not wear
clothing, apparel or jewelry that can become
entangled in moving parts. Always tie back or
cover long hair. Wear non-slip footwear to reduce
risk of slipping and losing control or accidentally
contacting cutting tool or moving parts.

HAZARDOUS DUST. Dust created by machinery
operations may cause cancer, birth defects, or
long-term respiratory damage. Be aware of dust
hazards associated with each workpiece mate­rial. Always wear a NIOSH-approved respirator to
reduce your risk.

HEARING PROTECTION. Always wear hear­ing protection when operating or observing loud
machinery. Extended exposure to this noise
without hearing protection can cause permanent
hearing loss.

REMOVE ADJUSTING TOOLS. Tools left on
machinery can become dangerous projectiles
upon startup. Never leave chuck keys, wrenches,
or any other tools on machine. Always verify
removal before starting!

USE CORRECT TOOL FOR THE JOB. Only use
this tool for its intended purpose—do not force
it or an attachment to do a job for which it was
not designed. Never make unapproved modifica­tions—modifying tool or using it differently than
intended may result in malfunction or mechanical
failure that can lead to personal injury or death!

AWKWARD POSITIONS. Keep proper footing
and balance at all times when operating machine.
Do not overreach! Avoid awkward hand positions
that make workpiece control difficult or increase
the risk of accidental injury.

CHILDREN & BYSTANDERS. Keep children and
bystanders at a safe distance from the work area.
Stop using machine if they become a distraction.

GUARDS & COVERS. Guards and covers reduce
accidental contact with moving parts or flying
debris. Make sure they are properly installed,
undamaged, and working correctly BEFORE
operating machine.

FORCING MACHINERY. Do not force machine.
It will do the job safer and better at the rate for
which it was designed.

NEVER STAND ON MACHINE. Serious injury
may occur if machine is tipped or if the cutting
tool is unintentionally contacted.

STABLE MACHINE. Unexpected movement dur­ing operation greatly increases risk of injury or
loss of control. Before starting, verify machine is
stable and mobile base (if used) is locked.

USE RECOMMENDED ACCESSORIES. Consult
this owner’s manual or the manufacturer for rec­ommended accessories. Using improper acces­sories will increase the risk of serious injury.

UNATTENDED OPERATION. To reduce the
risk of accidental injury, turn machine OFF and
ensure all moving parts completely stop before
walking away. Never leave machine running
while unattended.

MAINTAIN WITH CARE. Follow all maintenance
instructions and lubrication schedules to keep
machine in good working condition. A machine
that is improperly maintained could malfunction,
leading to serious personal injury or death.

DAMAGED PARTS. Regularly inspect machine
for damaged, loose, or mis-adjusted parts—or
any condition that could affect safe operation.
Immediately repair/replace BEFORE operating
machine. For your own safety, DO NOT operate
machine with damaged parts!

MAINTAIN POWER CORDS. When disconnect­ing cord-connected machines from power, grab
and pull the plug—NOT the cord. Pulling the cord
may damage the wires inside. Do not handle
cord/plug with wet hands. Avoid cord damage by
keeping it away from heated surfaces, high traffic
areas, harsh chemicals, and wet/damp locations.

EXPERIENCING DIFFICULTIES. If at any time
you experience difficulties performing the intend­ed operation, stop using the machine! Contact our
Technical Support at [phone].

Additional Safety for Jointers

Loss of workpiece con-

Serious cuts, amputation, entanglement, or death can occur from contact with rotating cutterhead
or other moving components! Flying chips can cause blindness or eye injuries. Workpieces or
inserts/knives thrown by cutterhead can strike nearby operator or bystanders with deadly force.
To reduce the risk of these hazards, operator and bystanders MUST completely heed the hazards
and warnings below.

KICKBACK. Occurs when workpiece is ejected

from machine at a high rate of speed. To reduce
the risk of kickback-related injuries, use quality
workpieces, safe feeding techniques, and proper
machine setup or maintenance.

GUARD REMOVAL. Operating jointer without
guard exposes operator to knives/inserts. Except
when rabbeting, never remove guards for regular
operations or while connected to power. Turn joint­er OFF and disconnect power before clearing any
shavings or sawdust from around cutterhead. After
rabbeting or maintenance is complete, immediate­ly replace all guards and ensure they are properly
adjusted before resuming regular operations.

DULL/DAMAGED KNIVES/INSERTS. Dull
knives/inserts can increase risk of kickback and
cause poor workpiece finish. Only use sharp,
undamaged knives/inserts.

OUTFEED TABLE ALIGNMENT. Setting outfeed
table too high can cause workpiece to hit table
and get stuck, increasing risk of kickback. Setting
outfeed table too low may cause workpiece to
become tapered from front to back. Always keep
outfeed table even with knives/inserts at top dead
center (highest point during rotation).

INSPECTING STOCK. Impact injuries or fire may
result from using poor workpieces. Thoroughly
inspect and prepare workpiece before cutting.
Verify workpiece is free of nails, staples, loose
knots or other foreign material. Workpieces with
minor warping should be surface planed first with
cupped side facing infeed table.

GRAIN DIRECTION. Jointing against the grain or
end grain can increase the risk of kickback. It also
requires more cutting force, which produces chat­ter or excessive chip out. Always joint or surface
plane WITH the grain.

MAXIMUM CUTTING DEPTH. To reduce risk of

1

kickback, never cut deeper than

⁄8" per pass.

CUTTING LIMITATIONS. Cutting a workpiece that
does not meet the minimum dimension require­ments can result in breakup, kickback, or acciden­tal contact with cutterhead during operation. Never
perform jointing, planing, or rabbeting cuts on

3

pieces smaller than 8" long,

PUSH BLOCKS. Not using push blocks when sur­face planing may result in accidental cutterhead
contact. Always use push blocks when planing
materials less than 3" high or wide. Never pass
your hands directly over cutterhead without a push
block.

WORKPIECE SUPPORT.

trol while feeding can increase risk of kickback or
accidental contact with cutterhead. Support work­piece continuously during operation. Position and
guide workpiece with fence. Support long or wide
stock with auxiliary stands.

FEED WORKPIECE PROPERLY. Kickback or
accidental cutterhead contact may result if work­piece is fed into cutterhead the wrong way. Allow
cutterhead to reach full speed before feeding.
Never start jointer with workpiece touching cutter­head. Always feed workpiece from infeed side to
outfeed side without stopping until cut is complete.
Never back work toward infeed table.

SECURE KNIVES/INSERTS. Loose knives or
improperly set inserts can become dangerous pro­jectiles or cause machine damage. Always verify
knives/inserts are secure and properly adjusted
before operation. Straight knives should never

SECTION 2: POWER SUPPLY

Before installing the machine, consider the avail­ability and proximity of the required power supply
circuit. If an existing circuit does not meet the
requirements for this machine, a new circuit must
be installed. To minimize the risk of electrocution,
fire, or equipment damage, installation work and
electrical wiring must be done by an electrician or
qualified service personnel in accordance with all
applicable codes and standards.

Electrocution, fire, or
equipment damage may
occur if machine is not
correctly grounded and
connected to the power

The full-load current rating is the amperage a
machine draws at 100% of the rated output power.
On machines with multiple motors, this is the
amperage drawn by the largest motor or sum of all
motors and electrical devices that might operate
at one time during normal operations.

The full-load current is not the maximum amount
of amps that the machine will draw. If the machine
is overloaded, it will draw additional amps beyond
the full-load rating.

If the machine is overloaded for a sufficient length
of time, damage, overheating, or fire may result—
especially if connected to an undersized circuit.
To reduce the risk of these hazards, avoid over­loading the machine during operation and make
sure it is connected to a power supply circuit that
meets the specified circuit requirements.

For your own safety and protection of

Note: Circuit requirements in this manual apply to

a dedicated circuit—where only one machine will
be running on the circuit at a time. If machine will
be connected to a shared circuit where multiple
machines may be running at the same time, con­sult an electrician or qualified service personnel to
ensure circuit is properly sized for safe operation.

A power supply circuit includes all electrical
equipment between the breaker box or fuse panel
in the building and the machine. The power sup­ply circuit used for this machine must be sized to
safely handle the full-load current drawn from the
machine for an extended period of time. (If this
machine is connected to a circuit protected by
fuses, use a time delay fuse marked D.)

This machine is prewired to operate on a power
supply circuit that has a verified ground and meets
the following requirements:

Improper connection of the equipment-grounding
wire can result in a risk of electric shock. The
wire with green insulation (with or without yellow
stripes) is the equipment-grounding wire. If repair
or replacement of the power cord or plug is nec­essary, do not connect the equipment-grounding
wire to a live (current carrying) terminal.

Check with a qualified electrician or service per­sonnel if you do not understand these grounding
requirements, or if you are in doubt about whether
the tool is properly grounded. If you ever notice
that a cord or plug is damaged or worn, discon­nect it from power, and immediately replace it with
a new one.

We do not recommend using an extension cord
with this machine.
cord, only use it if absolutely necessary and only
on a temporary basis.

Extension cords cause voltage drop, which can
damage electrical components and shorten motor
life. Voltage drop increases as the extension cord
size gets longer and the gauge size gets smaller
(higher gauge numbers indicate smaller sizes).

Any extension cord used with this machine must
be in good condition and contain a ground wire
and matching plug/receptacle. Additionally, it must
meet the following size requirements:

Grounding Requirements

This machine MUST be grounded. In the event
of certain malfunctions or breakdowns, grounding
reduces the risk of electric shock by providing a
path of least resistance for electric current.

This machine is equipped with a power cord that
has an equipment-grounding wire and a grounding
plug. Only insert plug into a matching receptacle
(outlet) that is properly installed and grounded in
accordance with all local codes and ordinances.
DO NOT modify the provided plug!

No adapter should be used with plug. If

The unpainted surfaces of your machine are
coated with a heavy-duty rust preventative that
prevents corrosion during shipment and storage.
This rust preventative works extremely well, but it
will take a little time to clean.

Be patient and do a thorough job cleaning your
machine. The time you spend doing this now will
give you a better appreciation for the proper care
of your machine's unpainted surfaces.

There are many ways to remove this rust preven­tative, but the following steps work well in a wide
variety of situations. Always follow the manufac­turer’s instructions with any cleaning product you
use and make sure you work in a well-ventilated
area to minimize exposure to toxic fumes.

Before cleaning, gather the following:

• Disposable rags

• Cleaner/degreaser (WD•40 works well)

• Safety glasses & disposable gloves

• Plastic paint scraper (optional)

Site Considerations

Weight Load

Refer to the
of your machine. Make sure that the surface upon
which the machine is placed will bear the weight
of the machine, additional equipment that may be
installed on the machine, and the heaviest work­piece that will be used. Additionally, consider the
weight of the operator and any dynamic loading
that may occur when operating the machine.

Space Allocation

Consider the largest size of workpiece that will
be processed through this machine and provide
enough space around the machine for adequate
operator material handling or the installation of

Requirements

• Scrape all glue off the workpiece before
jointing. Glue deposits on the workpiece,

hard or soft, will gum up the cutterhead and
produce poor results.

Follow these rules when choosing and joint­ing stock:

• DO NOT joint or surface plane stock that

contains large or loose knots. Injury to the

operator or damage to the workpiece can
occur if a knot becomes dislodged during the
cutting operation.

• Jointing and surface planing with the

grain is safer for the operator and pro­duces a better finish. Cutting against the

grain increases the likelihood of kickback
and workpiece tear-out. DO NOT cut against
the grain! Cutting with the grain is feeding
the stock across the cutterhead so the grain
points down and back, as viewed from the
front edge of the stock (see Figure 38).

Note: If the grain changes direction along the

edge of the workpiece, decrease the depth of
cut and make additional passes.

CORRECT

• Remove foreign objects from the
workpiece. Make sure that any stock you

process with the jointer is clean and free
of dirt, nails, staples, tiny rocks or any
other foreign objects that could damage the
cutterhead. These particles could also cause
a spark as they strike the cutterhead and cre­ate a fire hazard.

Note: Wood stacked on a concrete or dirt

surface can have small pieces of concrete or
stone pressed into the surface.

• Make sure all stock is sufficiently dried

before jointing. Wood with a moisture con­tent over 20% will cause unnecessary wear
on the cutters and poor cutting results. Excess
moisture can also hasten rust and corrosion.

• Make sure your workpiece exceeds the

minimum dimension requirements, as
shown in Figure 39, before processing it
through the jointer, or the workpiece may
break or kickback during the operation.

With Grain

INCORRECT

Against Grain

Figure 38. Proper grain alignment with the

cutterhead.

• Only process natural wood fiber through
your jointer. Your jointer is designed to cut
only natural wood stock. This machine is
NOT designed to cut metal, glass, stone, tile,
products with lead-based paint, or products
that contain asbestos—cutting these materi­als with a jointer may lead to injury.

Squaring Stock

Squaring stock involves four steps performed

Previously Surface

Planed Face

in the order below:

Squaring stock means making it flat and paral­lel along both length and width, and making the
length and width perpendicular to one another.

The purpose of squaring stock is to prepare it for
accurate cuts and construction later on.

A properly "squared up" workpiece is essential
for tasks such as accurate tablesaw cuts, glue­ups/laminations, cutting accurate bevels on a
bandsaw, and many other applications where
one surface of a workpiece is used to reference
another.

Surface Planing

The purpose of surface planing (see Figures

40–41) on the jointer is to make one flat face on

a piece of stock to prepare it for thickness planing

on a planer.

Inspect stock to ensure it is safe and suitable

for the operation (see
Requirements section).

Set infeed table height to desired cutting
depth for each pass.

NOTICE

If you are not experienced with a jointer,
set depth of cut to "0" and practice feeding
workpiece across the tables as described
for each of the jointing procedures. This
process will better prepare you for actual
operation.

Lubrication

Since all bearings are sealed and permanently
lubricated, simply leave them alone until they
need to be replaced. DO NOT lubricate them.

It is essential to clean components before lubri­cating them because dust and chips build up on
lubricated components and make them hard to
move. Simply adding more grease to them will not
yield smooth moving components.

Clean the components below with mineral spirits
or other oil/grease solvent cleaner and shop rags.

There are two options for setting the knives—the
straightedge method and the knife-setting jig
method. Each option has advantages and disad­vantages; the correct one for you will become a
matter of personal preference. For best results,
the tables must be parallel with each other (refer
to Checking/Adjusting Table Parallelism on
Page 42) and the outfeed table height must be
properly set (refer to Setting Outfeed Table

Height on Page 46).

Straightedge Method: A high quality straight-

edge (or Jointer Pal) is held flat against the
outfeed table and the knife heights are set to the
bottom of the straightedge, as shown in Figure

57. Because the knife projection height from the
cutterhead is dependent on the outfeed table
height, the outfeed table must be set as described
in Setting Outfeed Table Height on Page 46 for
this method to work correctly.

each of straightedge positions.

— If knives do not touch straightedge or they

lift up at any position, then those knives
need to be adjusted.

When using the straightedge method to set the
knives, you will not need to move the outfeed
table once it is set and you will always be assured
that the knives are even with the outfeed table in
their highest point of rotation (TDC)—even if the
cutterhead is not parallel with the outfeed table.

Rotating/Changing

This spiral cutterhead is equipped with index­able carbide inserts. Each insert can be rotat­ed to reveal any one of its four cutting edges.
Therefore, if one cutting edge becomes dull or
damaged, simply rotate it 90˚ to reveal a fresh
cutting edge as shown below.

Each insert has a reference dot on one corner.
As the insert is rotated, the reference dot location
can be used as an indicator of which edges are
used and which are new. When the reference dot
revolves back around to its starting position, the
insert should be replaced.

Adjusting Table Parallelism

For safe and proper cutting results, the tables
must be parallel to the cutterhead. Adjusting them
to be parallel is a task of precision and patience,
and may take up to one hour to complete. Luckily,
this is considered a permanent adjustment and
should not need to be repeated for the life of the
machine.

Due to the complex nature of this task, we rec­ommend that you double check the current table
positions to make sure that they really need to be
adjusted before starting.

Important: The steps below are intended to be
performed directly after the steps involved in
checking the outfeed table parallelism. Do not
continue until you have performed those steps.

To adjust table parallelism:

1. Place straightedge on outfeed table so it hangs

over cutterhead, and lower outfeed table until
straightedge just touches cutterhead body,
as shown in Figure 72.

Each table has four eccentric bushings on the
base underneath that allow the table to be adjust­ed parallel. Each bushing is locked in place by a
set screw.

The correct order for adjusting the table parallel­ism is to first adjust the outfeed table parallel with
the cutterhead, then adjust the infeed table paral­lel with the outfeed table.

When setting the outfeed table, all measurements
MUST be made from the cutterhead body—not
the knives/inserts or the results may be skewed.

until outfeed table is parallel with cutterhead.

5. Tighten/replace set screws in eccentric bush­ings on outfeed table.

6. Remove set screw from each of the four
eccentric bushings under infeed table.

6. Use motor pulley to rotate cutterhead until

one of the knives or inserts is at top dead
center (its highest point during rotation), as
illustrated in Figures 78–79.

The outfeed table height must be even with the
top of the cutterhead knives. If the outfeed table is
set too low, there will be snipe. If the outfeed table
is set too high, the workpiece will hit the edge of
the outfeed table during operation, increasing the
chance of kickback.

This includes the installation of unapproved after­market parts.

WIRE CONNECTIONS. All connections must
be tight to prevent wires from loosening during
machine operation. Double-check all wires dis­connected or connected during any wiring task to
ensure tight connections.

CIRCUIT REQUIREMENTS. You MUST follow
the requirements at the beginning of this manual
when connecting your machine to a power source.

WIRE/COMPONENT DAMAGE. Damaged wires
or components increase the risk of serious per­sonal injury, fire, or machine damage. If you notice
that any wires or components are damaged while
performing a wiring task, replace those wires or
components.

MOTOR WIRING. The motor wiring shown in
these diagrams is current at the time of printing
but may not match your machine. If you find this
to be the case, use the wiring diagram inside the
motor junction box.

CAPACITORS/INVERTERS. Some capacitors
and power inverters store an electrical charge for
up to 10 minutes after being disconnected from
the power source. To reduce the risk of being
shocked, wait at least this long before working on
capacitors.
