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-

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 Planers

Wood chips fly

PLANER INJURY RISKS. Familiarize yourself
with the main injury risks associated with plan­ers—always use common sense and good judge­ment to reduce your risk of injury. Main injury
risks from planers: amputation/lacerations from
contact with the moving cutterhead, entangle­ment/crushing injuries from getting caught in
moving parts, blindness or eye injury from flying
wood chips, or impact injuries from workpiece
kickback.

KICKBACK. Know how to reduce the risk of kick­back and kickback-related injuries. “Kickback”
occurs during the operation when the workpiece is
ejected from the machine at a high rate of speed.
Kickback is commonly caused by poor workpiece
selection, unsafe feeding techniques, or improper
machine setup/maintenance. Kickback injuries
typically occur as follows: (1) operator/bystanders
are struck by the workpiece, resulting in impact
injuries (i.e., blindness, broken bones, bruises,
death); (2) operator’s hands are pulled into blade,
resulting in amputation or severe lacerations.

REACHING INSIDE PLANER. Never remove
guards/covers or reach inside the planer during
operation or while connected to power. You could
be seriously injured if you accidentally touch the
spinning cutterhead or get entangled in moving
parts. If a workpiece becomes stuck or sawdust
removal is necessary, turn planer OFF and dis­connect power before clearing.

DULL/DAMAGED KNIVES/INSERTS. Only use
sharp, undamaged knives/inserts. Dull or dam­aged knives/inserts increase the risk of kickback.

INSPECTING STOCK. To reduce the risk of
kickback injuries or machine damage, thoroughly
inspect and prepare the workpiece before cutting.
Verify workpiece is free of nails, staples, loose
knots or foreign material. Workpieces with minor
warping should be jointed first or planed with the
cupped side facing the infeed table.

GRAIN DIRECTION. Planing across the grain
is hard on the planer and may cause kickback.
Plane in the same direction or at a slight angle
with the wood grain.

PLANING CORRECT MATERIAL. Only plane
natural wood stock with this planer. DO NOT
plane MDF, OSB, plywood, laminates or other
synthetic materials that can break up inside the
planer and be ejected towards the operator.

LOOKING INSIDE PLANER.

around inside the planer at a high rate of speed
during operation. To avoid injury from flying mate­rial, DO NOT look inside planer during operation.

CUTTING LIMITATIONS. To reduce the risk of
kickback hazards or damage to the machine, do
not exceed the maximum depth of cut or minimum
board length and thickness found in the Data

Sheet. Only feed one board at a time.

INFEED ROLLER CLEARANCE. The infeed

roller is designed to pull material into the spinning
cutterhead. To reduce the risk of entanglement,
keep hands, clothing, jewelry, and long hair away
from the infeed roller during operation.

FEED WORKPIECE PROPERLY. To reduce the
risk of kickback, never start planer with workpiece
touching cutterhead. Allow cutterhead to reach
full speed before feeding, and do not change feed
speed during cutting operation.

WORKPIECE SUPPORT. To reduce the risk of
kickback, always make sure workpiece can move
completely across table without rocking or tipping.
Use auxiliary support stands for long stock.

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.

BODY PLACEMENT. Stand to one side of planer
during the entire operation to avoid getting hit if
kickback occurs.

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

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:

property, consult an electrician if you are
unsure about wiring practices or electrical
codes in your area.

Model G0790 (Mfd. Since 9/15)

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 & Plug Requirements

Cleanup Site Considerations

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:

Bench Mounting

Another option is a "Direct Mount" (see example
below) where the machine is secured directly to
the workbench with lag screws and washers.

The base of this machine has mounting holes
that allow it to be fastened to a workbench or
other mounting surface to prevent it from moving
during operation and causing accidental injury or
damage.

The strongest mounting option is a "Through
Mount" (see example below) where holes are
drilled all the way through the workbench—and
hex bolts, washers, and hex nuts are used to
secure the machine in place.

Dust Port

Dust Collection

This machine creates substantial amounts
of dust during operation. Breathing air­borne dust on a regular basis can result in
permanent respiratory illness. Reduce your
risk by wearing a respirator and capturing
the dust with a dust collection system.

Recommended CFM at Dust Port: 250 CFM

Do not confuse this CFM recommendation with
the rating of the dust collector. To determine the
CFM at the dust port, you must consider these
variables: (1) CFM rating of the dust collector,
(2) hose type and length between the dust col­lector and the machine, (3) number of branches
or wyes, and (4) amount of other open lines
throughout the system. Explaining how to cal­culate these variables is beyond the scope of
this manual. Consult an expert or purchase a
good dust collection "how-to" book.

Workpiece Inspection

Some workpieces are not safe to use or may
require modification before they are. Before cut-

ting, inspect all workpieces for the following:

• Material Type: This machine is only intend­ed for workpieces of natural wood fiber
Attempting to use workpieces of any other
material that may break apart during opera­tion could lead to serious personal injury and
property damage.

• Foreign Objects: Inspect lumber for defects
and foreign objects (nails, staples, imbedded
gravel, etc,). If you have any question about
the quality of your lumber, DO NOT use it.
Remember, wood stacked on a concrete floor
can have small pieces of stone or concrete
pressed into the surface.

• Large/Loose Knots: Loose knots can
become dislodged during operation. Large
knots can cause kickback and machine dam­age. Always use workpieces that do not have
large/loose knots.

• Wet or "Green" Stock: Avoid using wood
with a high water content. Wood with more
than 20% moisture content or wood exposed
to excessive moisture (such as rain or snow),
will cut poorly and cause excessive wear to
the machine. Excess moisture can also has­ten rust and corrosion of the machine and/or
individual components.

• Excessive Warping: Workpieces with exces­sive cupping, bowing, or twisting are danger­ous to cut because they are unstable and
often unpredictable when being cut. DO NOT
use workpieces with these characteristics!

• Minor Cupping: Workpieces with slight cup­ping can be safely supported if the cupped
side is facing the table. On the contrary,
a workpiece supported on the bowed side
will rock during operation and could cause
severe injury from kickback.

Wood Types

The species of wood, as well as its condition,
greatly affects the depth of cut the planer can
effectively take with each pass.

The chart in the figure below shows the Janka
Hardness Rating for a number of commonly
used species. The larger the number, the harder
the workpiece, and the less material should be
removed in any one pass for good results.

Note: The Janka Hardness Rating is expressed in
pounds of force required to embed a 0.444" steel
ball into the surface of the wood to a depth equal
to half the ball's diameter.

Planing Tips

Cutting Problems

• Inspect your lumber for twisting or cupping,

and surface one face on a jointer if necessary
before planing workpiece.

• Scrape off all glue when planing glued-up
panels. Dried glue can quickly dull knives.

• DO NOT plane more than one piece at a
time.

• Never remove more than the recommended
amount of material on each pass. Only
remove a small amount of material on each
pass when planing wide or dense stock.

• Support the workpiece on both ends. Get
assistance from another person if you are
planing long lumber, or use roller stands to
support the workpiece.

• Measure the workpiece thickness with cali-
pers to get exact results.

• Carefully inspect all stock to make sure it is
free of large knots or foreign objects that may
damage your knives, cause kickback, or be
ejected from the planer.

• When possible, plane equal amounts on
each side of the board to reduce the chance
of twisting or cupping.

• Use the entire width of the planer to wear
knives evenly. With narrow workpieces, alter­nate between far left, far right, and the middle
of the table. Your knives will remain sharp
much longer.

• To avoid "chip marks," always plane WITH
the grain direction of the wood. Never plain
cross-grain or end-grain.

• Plane ONLY natural wood fiber. Do not
plane wood composites or other materials
that could break up in the planer and cause
operator injury or damage to planer.

Below is a list of wood characteristics you may
encounter when planing. The following descrip­tions of defects will give you some possible
answers to problems you may encounter while
planing different materials. Possible solutions fol­low the descriptions.

Chipped Grain

Problem: Usually a result of cutting against the

grain, planing lumber with knots or excessive
amount of cross grain, or using dull knives.

Solution: Decrease the depth of cut. Inspect
your lumber and determine if its grain pattern is
causing the problem. If the lumber does not show
substantial crossgrain, inspect your knives.

Fuzzy Grain

Problem: Usually caused by surfacing lumber

with too high of a moisture content. Sometimes
fuzzy grain is an unavoidable characteristic of
some woods, such as basswood. Fuzzy grain can
also be caused by dull knives.

Solution: Check the lumber with a moisture
meter. If moisture is greater than 20%, sticker the
lumber and allow it to dry. Otherwise, inspect the
knife condition.

Snipe

Problem: Occurs when board ends have more

material removed than the rest of the board.
Usually caused when the workpiece is not prop­erly supported as it goes through the machine. In
many cases, however, a small amount of snipe is
inevitable.

Solution: The best way to deal with snipe is by
planing lumber longer than your intended work
length and then cutting off the excess after plan­ing is completed.

• Always true cupped or warped stock on a
jointer before planing.

Model G0790 (Mfd. Since 9/15)

-19-

Pitch & Glue Build-up

Problem: Glue and resin buildup on the rollers

and cutterhead will cause overheating by decreas­ing cutting sharpness while increasing drag in the
feed mechanism. The result can include scorched
lumber as well as uneven knife marks and chatter.

Solution: Clean the rollers and cutterhead.

Depth of Cut

The planing depth on the Model G0790 is con­trolled by the cutterhead elevation crank on top of
the planer. Turning the crank clockwise raises the
cutterhead; turning it counterclockwise lowers the
cutterhead.

Chip Marks or Indentations

Problem: Chip indentation or chip bruising is the

result of wood chips not being thrown away from
the cutterhead and out of the machine. Instead
they are carried around the cutterhead, deposited
on the planed surface and crushed by the outfeed
roller. Chip indentations can be caused by a num­ber of reasons, some of which are:

• The type of lumber being planed. Certain
species have a tendency to chip bruise.

• A high moisture content (over 20%) or sur-
face moisture. Typically found in air-dried
stock where the surface is dry but the inside
needs a longer time to season.

• Dull knives.

• Too much material being removed in one

pass.

Solution:

Elevation Crank

The elevation crank provides a simple and accu­rate method for producing cuts of consistent
depth on multiple passes.

The pitch of the elevation leadscrew is 16 TPI
(threads per inch), meaning that every turn of the
crank will move the cutterhead
a base, you can make passes with a depth of cut

• Lumber must be completely dry, preferably
kiln-dried (KD). Air-dried (AD) lumber must
be seasoned properly and have no surface
moisture. DO NOT surface partially-air-dried
(PAD) lumber.

• Make sure planer knives are sharp.

• Reduce depth of cut.

Figure 14. Crank elevation increments.

Note: Any time you switch directions with the

cutterhead elevation crank, there will be a small
amount of backlash—so the first turn of the crank
after switching directions will be slightly less than

1

⁄16". However, as long as you move the crank in
the same direction during the operation, backlash
will not be a factor.

Although the correct depth of cut varies according
to wood hardness and workpiece width, we rec­ommend a maximum depth of cut no more than

1

⁄32". A series of light cuts will give better results
and put less stress on the planer than trying to
take off too much material in a single pass.

Model G0790 (Mfd. Since 9/15)

Elevation Scale

The depth of cut is read directly from the elevation
scale (see Figure 15) on the righthand column at
the front of the machine. The measurement indi­cated by the red arrow is the effective thickness
of the board after planing.

Feeding Workpiece

The feed rate on this planer is automatically set
at 26 FPM. Infeed and outfeed rollers move the
workpiece through the planer while keeping it flat
and providing a consistent rate of movement.

Column

Scale

Red Arrow

Figure 15. Positioning elevation scale.

Example: If you need to plane a board down to

1", simply make multiple passes (no greater than
the maximum depth of cut) until the cutterhead
elevation scale reads 1". A final pass at this set­ting will create a 1" thick workpiece.

Note: The cutterhead elevation scale does not
provide a precise measurement and should only
be used for approximate measurements. If pre­cise workpiece thicknesses are needed, use
calipers to ensure your workpieces meet your
standards.

To feed workpiece into planer:

1. Place workpiece on table so it is perpendicu-

lar to cutterhead, with side to be planed fac­ing up toward cutterhead.

Note: Boards more than 24" long should be

supported on both sides of planer.

2. Lower cutterhead until depth bar (see Figure

16) just touches workpiece.

Note: Any time you switch directions with

you move handle in same direction during
operation, backlash will not be a factor.

workpiece from planer.

4. Turn planer ON.

5. With flat side of board facing down on table,

feed workpiece into front of planer, making
sure not to stand directly in front or behind
workpiece to reduce the risk of a kickback
injury.

— If cut is too deep and bogs down planer,

turn planer OFF immediately, allow it to
come to a complete stop, raise cutterhead,
remove workpiece, reduce depth of cut,
then repeat Step 5.

6. Once workpiece is clear of outfeed roller,
measure workpiece thickness. If further plan­ing is needed, lower cutterhead by turning

1

elevation crank handle ½ turn (

⁄32"), return
the workpiece to the infeed table, then con­tinue.

7. Continue this process until desired thick­ness is reached. Depth of cut indicator scale
shows approximate thickness of workpiece
after it has been cut. Use this indicator to
judge when thickness is approximately cor­rect. For more precise applications, use a
caliper to measure workpiece thickness.

Note: Infeed and outfeed rollers will control

feed rate of workpiece as it passes through
planer. Do not push or pull on workpiece.

The cutterhead knives on Model G0790 are
extremely sharp. Accidental contact with
knives can result in severe cuts. Take great
caution whenever working with or around
cutterhead knives. Wear heavy leather
gloves to reduce risk of severe cuts.

Removing Knives

1. DISCONNECT MACHINE FROM POWER!

To maintain accurate and consistent plan­ing results, we do not recommend sharpen­ing knives yourself. Instead, just replace
dull knives or have them professionally
sharpened.

The knives on the Model G0790 Planer are
reversible and should always be reversed or
replaced as a matched set. To avoid downtime,
we recommend having an extra set of knives for
your planer. Once the cutterhead, gib, and knives
have been inspected and prepared, install the
knives.

Before re-installing the knives, the cutterhead,
gib and knife must be inspected. Neglecting to
inspect these components may result in damage
to the planer.

The condition of the knives on the Model G0790
will affect the precision of the cut. During opera­tion, watch for the following signs of dulled knives.

• Raised grain occurs as a result of dull knives
hammering at the surface of the wood.

2. Remove (2) M5-.8 x 10 cap screws from
cutterhead guard, then remove guard (see

Figure 27).

Note: Cutterhead guard locks in place.

After removing cap screws, slide guard right

disassembly.

• A "fuzzy" appearance on the surface of the
wood occurs as a result of dull knives tearing,
rather than cutting the wood fibers.

• Ridges occur as a result of nicks along the
knife edge.

• Difficulty feeding the workpiece into the
planer.

If any of these signs become apparent during use,
the knives should be reversed or replaced.

Inspecting Cutterhead, Gib, and Knives

1. DISCONNECT PLANER FROM POWER!

2. Carefully clean the cutterhead with a rag and

with a flashlight, inspect the following:

• Make sure the threaded screw holes do

not contain wood material or sawdust.

• Make sure that the hex socket and the

threads of all cap screws are in good con­dition. Replace if questionable.

• Make sure any resin or glue buildup

on the cutterhead, gib, and knives is
removed so the knife and gib will sit flat
on the cutterhead.

Pins

Figure 29. Example of knife installation.

3. Using magnets, place gib over knife. Secure

gib with (6) M6-1 x 16 cap screws (see

Figure 30) removed earlier.

Brushes

This motor is equipped with two long-life carbon
brushes. However, brush life expectancy is affect­ed by motor loading. Regularly planing very wide,
dense boards or cutting too deeply will reduce
brush life.

Check brushes if motor loses power or becomes
noisy. Replace the carbon brushes when the motor
no longer reaches full power or if brushes mea­sure less than

The cutterhead is driven by a belt that is located
on the right-hand side of the motor and cutterhead
assembly (when facing the front of the machine).
The belt is very durable, but with extended use it
may begin to stretch and slip, indicating the need
for tightening or replacement.

Scale Calibration

Feed Rollers

Although correctly set at the factory, the scale can
be adjusted for accuracy if it becomes necessary.

Tools Needed Qty

Phillips Screwdriver #2 ...................................... 1

Scrap Piece of Stock ......................................... 1

Calipers ............................................................. 1

To reposition scale:

1. Plane scrap piece of stock until it is flat on

both sides and has even thickness along its
length.

Note: Turn scrap board over between each

pass to make surfaces parallel.

2. Use calipers to measure board thickness.

3. If there is a discrepancy between board thick-

ness and reading on elevation scale, loosen
the M6-1 x 12 Phillips head screw shown in
Figure 35, adjust position of red pointer to
indicate correct thickness, then re-tighten
screw.

The feed rollers rotate in bushing blocks that are
spring loaded. The feed rollers ride up on the
board so that the roller pressure is maintained.
If chips or sawdust build up between the bracket
and bushing block (see Figure 36), the amount
of roller vertical travel will be reduced, potentially
causing improper feeding of workpiece through
the machine.

Bracket

Periodically check and clean chips and sawdust
from between the bushing blocks and brackets.

Sawdust can get trapped between the

bushing block and the bracket.

Table Height

Adjustment

The table and cutterhead are checked for paral­lelism at the factory. However, over long periods
of use, parallelism may be affected. To restore
parallelism between the table and the cutterhead,
perform the following steps.

NOTICE

During next step, DO NOT let chain fall off
sprockets. It can be very difficult to return
chain to proper location on sprockets with­out changing table adjustments.

4. Loosen (2) M5-.8 x 10 cap screws on idler

bracket to loosen chain. Do not remove
chain.

Tools Needed Qty

Hex Wrench 4mm .............................................. 1

To adjust table height:

1. Plane a test piece of wood. Measure amount

of taper from front to back and side to side.
Determine which corner(s) of table need to
be adjusted.

2. DISCONNECT MACHINE FROM POWER!

3. Gently tilt machine onto its side (see Figure

37) to expose table height chain and sprock-

ets.

Table Height Chain

Note: The goal in the next step is to adjust the

height of the table by rotating the leadscrew
sprockets at the corners of the base (see
Figure 38).

5. Gently lift chain clear of one leadscrew
sprocket at a time. Rotating sprocket by
one tooth will move that corner of table by
approximately 0.006".

6. When satisfied with adjustments, re-tighten
idler bracket with cap screws. Set machine
back on its base.

7. Perform a test cut to verify parallelism. If
cutterhead and table are not parallel, perform
Steps 3–6 again.
