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.

Alerts the user to useful information about proper operation of the

NOTICE

machine to avoid machine damage.

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 your 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 -

G0890/G0891 (Mfd. Since 10/20)

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

Amputation, serious cuts, entanglement, or death can occur from contact with rotating
cutterhead or other moving parts! Flying chips can cause eye injuries or blindness. Workpieces
or 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 hazards and
warnings below.

KICKBACK. Know how to reduce the risk of kick-

back 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.

AVOID CONTACT WITH MOVING PARTS. 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 table.

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. Wood chips fly
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.

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

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.

-12-

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.

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.

or equipment damage
may occur if machine is
not properly grounded
and connected to 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.

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

Grounding Instructions

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.

The power cord and plug specified under “Circuit
Requirements for 230V”
has an equipment-grounding wire and a ground­ing prong. The plug must only be inserted into
a matching receptacle (outlet) that is properly
installed and grounded in accordance with all local
codes and ordinances (see following figure).

Serious injury could occur if you connect

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:

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.

Cleanup

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)

Basic steps for removing rust preventative:

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
auxiliary equipment. With permanent installations,
leave enough space around the machine to open
or remove doors/covers as required by the main­tenance and service described in this manual.

See below for required space allocation.

Dust Collection

Checking Gearbox

Oil Level

This machine creates a lot of wood chips/
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.

Minimum CFM at Dust Port: 400 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.

To connect the machine to a dust-collection sys­tem, fit a 4" dust hose over the dust port, and
secure in place with a hose clamp (see Figure 13).
Tug the hose to make sure it does not come off.

Before starting your machine for the first time,
check the gearbox oil level. The proper oil level
is just even with the bottom of the fill plug hole.
The gearbox uses ISO 320, SAE 140 gear oil, or
SAE 85W–140 multi-weight gear oil. DO NOT mix
oil types.

Note: For easier access to the fill plug, remove
the gearbox cover (see Figure 14).

To check gearbox oil level:

Remove gearbox fill plug (see Figure 14).

Gearbox Cover

Fill Plug

Note: A tight fit is necessary for proper
performance.

Figure 13. Example of dust hose connected to

dust port.

Figure 14. Location of gearbox fill plug.

2. Dip short end of a clean 6mm hex wrench

inside fill hole, and then remove it.

— If the end of the hex wrench is coated

with oil, then the gearbox oil level is okay.
Replace the fill plug and continue setup.

— If the end of the hex wrench is not coated

with oil, then you need to add more oil.
Refer to Gearbox Oil on Page 34 for
instructions on how to do this.

Note: We recommend that you replace the gear-
box oil after the first 20 hours of operation. This is
a normal break-in procedure and will help maxi­mize the service life of the machine by flushing
away any particles from the break-in and manu­facturing process.

Adjustments

The adjustments listed below have been per­formed at the factory. However, because of the
many variables involved with shipping, we recom­mend that you verify the adjustments to ensure
the best possible results from your new machine.

Step-by-step instructions for these adjustments
can be found in the SERVICE section starting on

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:

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

Note: Some amount of chipping is normal with
highly figured wood.

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

your knives/inserts.

Fuzzy Grain

Problem:

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/inserts.

Solution:

meter. If moisture is greater than 20%, sticker the
lumber and allow it to dry. Otherwise, inspect the
knife/insert condition.

Snipe

Problem

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 outfeed end of the planer. 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.

before planing workpiece.

Scrape off all glue when planing glued-up

panels. Dried glue can quickly dull knives/
inserts.

DO NOT plane more than one piece at a time.

Never plane multiple pieces side by side.

Never remove more than the recommended

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.

each side of the board to reduce the chance
of twisting or cupping.

Use the entire width of the planer to wear

knives/inserts evenly. With narrow workpiec­es, alternate between far left, far right, and
the middle of the table. Your knives/inserts
will remain sharp much longer.

To avoid "chip marks," always plane WITH

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, uneven knife/insert marks, and chatter.

Solution:

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. Some of the causes of chip indentation are:

• Wood chips/sawdust not being properly

Depth of Cut

Headstock Movement per Handwheel Revolution

One Full Revolution

Material Thickness Range

Minimum–Maximum Stock Thickness

The depth of cut on a planer means the amount
of material that is removed from the top of the
workpiece as it passes underneath the cutterhead.

The depth of cut is set by adjusting the distance
of the table below the cutterhead. This distance
is the thickness of the workpiece minus the depth
of cut. The planing depth of cut is controlled by
using the headstock elevation handwheel on the
right side of the machine. Rotating the handwheel
clockwise raises the headstock.

Use a proper dust-collection system; adjust

chip deflector in or out as necessary.

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/inserts are sharp.

Reduce depth of cut.

Although the correct depth of cut varies accord­ing to wood hardness and workpiece width, we
recommend the maximum depth of cut (per pass)
be no more than

planer than trying to take off too much material in
a single pass.

The depth of cut can be referenced directly from
the inch/millimeter scale on the front of the planer,
as shown.

Setting Feed Rate Adjusting/Replacing

The infeed and outfeed rollers move the work­piece through the planer while keeping it flat and
providing a consistent rate of movement. The
speed that these rollers move the workpiece
through the planer is the feed rate.

Generally, low feed rates are used for finishing
passes, while higher feed rates are used for
dimensioning passes.

The figure below illustrates the three different
positions of the feed rate control knob:

• Push knob in to use high feed rate.

• Pull the knob out to use the low feed rate.

• Move knob to center position to place gear­box in neutral.

Note: Proper cleaning of insert, Torx screw,

and cutterhead pocket is critical to achieving
a smooth finish. Dirt or dust trapped between
insert and cutterhead will raise insert, and
make marks on your workpiece when planing.

NOTICE

Failure to follow reasonable lubrication
practices as instructed in this manual for
your machine could lead to premature fail­ure of components and void the warranty.

This planer features bearings that are lubricated
and sealed at the factory. These bearing do not
require any further attention unless they need
to be replaced. If a bearing fails, your planer will
probably develop a noticeable rumble or vibration,
which will increase when the machine is under a
load. The bearings are standard sizes and can be
replaced through Grizzly.

Follow the maintenance schedule on this page
and the procedures beginning on Page 33 to
properly lubricate the other planer components,
which are essential for long life and trouble-free
operation of your planer.

Roller Heights

It is essential that the feed rollers are set at the
correct distance below the cutterhead knives
at BDC (bottom dead center) to ensure that the
workpiece moves through the planer evenly and
the correct distance from the cutterhead knives.

To ensure accurate results and make the adjust­ment process quicker and easier, we recommend
using a Rotacator for these adjustments (refer to
Accessories).

If a Rotacator is not available, a 6' 2x4 cut into two
even sized pieces and a feeler gauge set can be
used, but care must be taken when jointing the
wood to achieve accurate results.

Note: The chip breaker is spring mounted, which
allows it to adjust automatically to the workpiece.
No adjustment is necessary.

Adjusting Roller

The infeed and outfeed rollers keep the workpiece
moving through the planer. Springs exert down­ward pressure on the feed rollers while allowing
them to raise with an uneven workpiece surface.
Proper spring tension is crucial to keep the work­piece moving through the planer during operation.

The ideal feed-roller spring tension varies depend­ing upon the type of wood you plane. When
adjusting spring tension, keep the following in
mind:

• If you are planing milled lumber with a con-

• If you are planing rough lumber with incon-

• If the workpiece consistently stops feeding
during operation, the spring tension may

Calibrating Headstock

The anti-kickback fingers are an important safety
feature of your planer. The fingers hang from a rod
suspended across the head casting and in front of
the infeed roller, as shown. This design allows the
workpiece to easily enter the planer but reduces
the risk of kickback by digging into the workpiece
if it moves backward.

Check the anti-kickback fingers regularly to ensure
they swing freely and easily. If the fingers do not
swing freely and easily, first clean them with a
wood-resin solvent, then inspect them for dam­age. If any of the fingers are damaged, the device
must be replaced before using the machine.

Do not apply oil or other lubricants to the anti-kick­back fingers that will attract dust and restrict free

Tensioning Headstock

Adjusting Cutterhead

Height Chain

The headstock height chain transfers movement
from the elevation handwheel to the columns that
control headstock height. The chain drive can be
adjusted to remove slack if the chain stretches
over time or is loosened during headstock leveling
procedures.

Items Needed Qty

Parallelism

Maximum Allowable Tolerances:

Cutterhead/Table Side-to-Side
Head Casting/Table Front/Back

Cutterhead parallelism is critical to the operation
of the machine. As such, it is essential that the
Cutterhead is parallel with the table (within 0.002")
from side-to-side, as illustrated in Figure 49.

NOTICE

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

How the table sits in relation to the head casting
from front-to-back is also important (see Figure

50). Because the feed rollers and chip breaker will
be adjusted off the table position, the tolerances
on the front-to-back positioning are not as critical
as the cutterhead/table side-to-side positioning.
Therefore, the maximum allowable tolerance for
the front-to-back parallelism is not more than

0.020".

Cutterhead Parallelism Inspection

Use your Rotacator to inspect the cutterhead par­allelism. If you do not have a Rotacator, a wood
block and feeler gauges may be used, but extra
care must be taken to ensure accuracy. If the
cutterhead is not within the maximum allowable
tolerances, it must be adjusted.

Headstock Parallelism Adjustments

The headstock is adjusted by turning the chain
sprockets underneath the table for movements
over 0.008" or by adjusting how the headstock is
mounted on the columns for movements under

0.008".

NOTICE

When making adjustments, tighten fasten­ers after each step to ensure the accuracy
of your tests. When adjusting the chain
sprockets, keep in mind that if the chain
becomes too loose, it will fall off of all the
sprockets, and returning it to its proper
location can be extremely difficult.

6. Carefully rotate sprocket (clockwise to raise

headstock; counterclockwise to lower head­stock) just enough to position next tooth
at marked location, then fit chain around
sprocket again.

Repeat Steps 4–6 with each sprocket that

7.

needs to be adjusted until table-to-cutterhead
clearance is within 0.008" from one side to
the other.

8. Make sure chain is properly fitted on sprock­ets, then re-tighten idler sprocket and lock
bolts.

If necessary, micro-adjust headstock position

9.

by loosening cap screws shown in Figure 51
and raising or lowering headstock until it is
properly aligned with table.

Note: This process may require adjusting the

columns on both the left and right hand sides
until you find the correct combination.

To adjust headstock parallelism:

1. DISCONNECT MACHINE FROM POWER!

Remove cabinet panel and locate chain on

2.

underside of table.

Loosen idler sprocket (see Chain Tension

3.

instructions on Page 33).

Move chain away from sprocket you want to

4.

adjust so only that sprocket can be rotated
independent of chain.

Note: If the left side of the table is too high,

the left two sprockets will need to be adjust­ed. Each tooth on the sprocket represents
.008" of vertical movement as the cogs are
turned. Make sure, as you turn the sprockets,
to keep an accurate tooth count to ensure
that the headstock is adjusted equally.

Mark location of one tooth of sprocket that
