3.0 Safety warnings

1. Read and understand the entire owner's manual before attempting assembly or operation.

2. Read and understand the warnings posted on the machine and in this manual. Failure to comply with all of
these warnings may cause serious injury.

3. Replace the warning labels if they become obscured or removed.

4. This Woodworking Jointer-planer is designed and intended for use by properly tra ined and experienced
personnel only. If you are not familiar with the proper and safe operation of a woodworking jointer or
planer, do not use until proper training and knowledge have been obtained.

5. Do not use this for other than its intended use. If used for other purposes, JET disclaims any real or implied
warranty and holds itself harmless from any injury that may result from that use.

6. Always wear approved safety glasses/face s hields while using this woodworking jointer-planer. Everyday
ey eglass es only h ave impact r esistant lenses; they are not safe ty glasses.

7. Before operating this woodworking jointer-planer, remove tie, rings, watches and other j ewelry, and roll
sleeves up past the elbows. Remove all loose clothing and confine long hair. Non-slip footwear or anti-skid
floor strips are recommended. Do not wear gloves.

8. Wear ear protectors (plugs or muffs) during extended periods of operation.

9. Some dust created by power sanding, sawing, grinding, drilling and other construction activities contain
chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these
chemicals are:

• Lead from lead based paint.

• Crystalline silica from bricks, cemen t and other masonry products.

• Arsenic and chromium from chemically treated lumber.

Your risk of exposure varies, depending on how often you do this type of work. To reduce your exposure to
these chemicals, work in a well-ventilated area and work with approved safety equipment, such as face or
dust masks that are specifically designed to filter out microscopic particles.

10. Do not operate this machine while tired or under the influence of drugs, alcohol or any medication.

11. Make certain the switch is in the OFF position before connecting the machine to the power source.

12. Make certain the machine is properly grounded.

13. Make all machine adjustments or maintenance with the machine unplugged from the power source.

14. Remove adjusting keys and wrenches. Form a habit of checking to see that keys and adj usting wrenches
are removed from the machine before turning it on.

15. Keep safety guards in place at all times when the machine is in use. If removed for maintenance purposes,
use extreme caution and replace the guards immediately.

16. Make sure the woodworking jointer-planer is firmly secured to the floor or bench before use.

17. Check damaged parts. Before further use of the machine, a guard or other part that is damaged should be
carefully checked to determine that it will operate properly and perform its intended function. Check for
alignment of moving parts, binding of m oving parts, breakage of parts, mounting and any ot her conditions
that may affect its operation. A guard or other part that is damaged should be properly repaired or
replaced.

18. Provide for adequate space surrounding work area and non-glare, overhead lighting.

19. Keep the floor around the machine clean and free of scrap material, oil and grease.

20. Keep visitors a safe distance from the work area. Keep children away.

21. Make your workshop child proof with padlocks, master switches or by removing starter keys.

4

22. Give your work undivided attention. Looking around, carrying on a conversation and “horse-play” are
careless acts that can result in serious injury.

23. Maintain a balanced stance at all times so that you do not fall or lean against t he cutterhead or other
moving parts. Do not overreach or use excessive force to perform any machine operation.

24. Use the right tool at the correct speed and feed rate. Do not force a tool or attachment to do a job for which
it was not designed. The right tool will do the job better and safer.

25. Use recommended accessories; improper accessories may be hazardous.

26. Maintain tools with care. Keep knives sharp and clean for the best and safest performance. Follow
instructions for lubricating and changing accessories.

27. Turn off the machine before cleani ng. Use a brush or com pressed air to remove chips or debris — do not
use your hand s.

28. Do not stand on the machine. Serious injury could occur if the machine tips over.

29. Never leave the machine running unattended. Turn the power off and do not leave the machine until it
comes to a complete stop.

30. Before turning on machine, remove all extra equipment such as keys, wrenches, scrap, stock, and cleaning
rags away from the machine.

31. Always use a hold-down or push block when surfacing stock less than 12" inches long, or 3 inches wide, or
3 inches thick.

32. Do not perform jointing operations on material shorter than 8", n a rrower than 3/4" or less than 1/4" thick.

33. The hands must never be closer t han 3 inches to
the cutterhead (see Figure).

34. Never apply pressure to stock directly over the
cutterhead. This may result in the stock tipping into
the cutterhead along with the operator's fingers.
Position hands away from extreme ends of stock,
and push through with a smooth, even motion.
Never back workpiece toward the infeed table.

35. To avoid kickback, the grain must run in the same
direction you are cutting. Before attempting to joint,
or plane, each work piece must be carefully
examined for stock condition and grain orientation.

36. When working with a swirl grain wood or burls,
making it necessary to plane against the grain, use a lesser depth of cut and a slow rate of feed.

37. Move the hands in an alternate motion from back to front as the work continues through the cut. Never
pass the hands directly over the cutter knife. As one hand approaches the knives remove it from the stock
in an arc motion and place it back on the stock in a position beyond the cutter knife (Fig. 2).

38. At a ll times h old the stock firmly.

39. Do not use this for other than it intended use. If used for other purposes, JE T d isclaims a ny real or im plied
warranty and holds itself harmless for any injury or damage which may result from that use.

11.0 Adjustments

11.1 Cutterhead Knife Adjustment

Cutterhead knives are

dangerously sharp! Use extreme ca ution when
inspecting, removing, sharpening or replacing
knives into the cutterhead. Failure to comply
may cause serious injury!

Determining if adjustment is necessary:

1. Disconnect machine from the power source.

2. Remove the cutterhead guard.

Refer to Figures 16 and 17:

7. When the blade is at the proper height,
alternately tighten the six gib lock screws (A).

Repeat steps 3 – 7 to adjust the remaining blade.
Note: The most common cause for unsatisfactory

cutting performance is improperly set knives. Many
aftermarket devices are avaialable to further assist
in the accurate setting of knives.

Note: To rotate the cutterhead the cutterhead
pulley must be turned. This require s removing the
panel on the front of the cabinet for access.

3. Rotate the cutterhead (E ) until one knife is i n
the 12 o'clock position. The 12 o'clock position
is the highest point a blade will reach in the
cutting arc (C, Figure 17).

4. Place the knife setting gauge (J) on the
outfeed table (F). One end of the gauge should
be positioned over the cutting knife (C)
towards the near the end of the blade (G).

Use care when handling the

knife setting gauge near the blades to pr event
damage.

Note the position of the knife blade with respect to
the gauge, then move the gauge to the other side
of the table towards the fence (H) and again note
the position of the knife blade with respect to the
gauge.

The blade must be at the same height at each end
and must also be at the same height as the
outfeed table (bottom of gauge). If this is not the
case, adjustment is required as follows:

Adjustment procedure

2. Loosen jam nut (E) and adjust stop screw (D)
in or out until a fence postion of 90º with
respect to the table is achieved.

3. Secure the jam nut (E).

Check the scale indication. If the indicator (C) does
not point to zero:

4. Loosen screw (B), adjust accordingly, then
retighten screw.

Fence 45º Adjustment

Verify that the fence and scale indication is
accurate at 90º as outlined in Fence 90º
Adjustment above.

1. Loosen lock handle (H) and set the fence all
the way back. Using a square, determine if the
fence is 135º to the table.

If adjustment is required:

2. Loosen jam nut (G) and adjust stop screw (F)
in or out until a fence postion of 135º with
respect to the table is achieved. Note: The

forward position (90º to table, corresponding to a
scale reading of 0º) to a f ull back-tilted position of
135 º (scale reading of 45 º).

Figure 18

Disconnect machine from
power source before making any adj ustments.
Failure to comply may cause serious injury.

11.4.1 Feed-roller belt replacement

Cutterhead knives are

dangerously sharp. Use extreme caution when
replacing any belt. Contact with cutterhead
knives will cause serious injury.

1. Remove the front panel. This is the panel

where the Start/Stop switc h is loc a t e d .

2. Remove feed-roller belt (A) from pulley (B)

while man ually rota ting pulley (C).
When this is accomplished, belt will fall away

from pulley (C).

3. Loop the new belt around pulley (C), then

4. When installed, continue to manually rotate
pulley (C) and verify that belt is properly
seated on both pulleys.

5. Replace front cover.

6. Loop belt around pulley (E) while manually
rotating pulley (F).

Use extreme caution to avoid

contact with cutterhead knives while
performing this step. Contact with cutterhead
knives will cause serious injury.

7. Manually rotate pulley (F) to verify that the
grooves in the belt are properly meshed with
the grooves on both pulleys.

This completes the cutterhead drive belt
installation.

8. Replace the feed-roller belt (Feed-roller Belt
Replacement section steps 3–5).

12.0 Basic Operations

12.1 Dust collection

Before initial operation, the machine must be
connected to a dust collector.

Important: If a dust collection system is not used,
the quality of your cut will suffer severely.

Figure 19

11.4.2 Cutterhead drive belt replacement

Cutterhead knives are

dangerously sharp. Use extreme caution when
replacing any belt. Contact with cutterhead
knives will cause serious injury.

The cutterhead drive belt should seldom if ever,
require replacement. Follow the procedure below if,
however, the belt should require replacement.

1. Remove the feed-roller belt as described in
Feed-roller Belt Replacement above.

2. Remove the bottom portion of the cutterhead
drive belt (D) from pulley (E) while manually
rotating pulley (F).

Use extreme caution to avoid

contact with cutterhead knives while
performing this step. Contact with cutterhead
knives will cause serious injury.

3. Remove top portion of belt (D ) from pulley F,
then work it under the chain and past pulley B
to remove completely.

12.2 Initial startup

After the assembly and adjustments are complete
the planer is ready to be tested. Plug in and start
the machine. Keep your finger on the Stop button
in case of a problem. The machine should run
smoothly with little or no vibration or rubbing
noises. Investigate and correct the source of any
problems before further operation.

DO NOT attempt to investigate

or adjust the planer while it is running. Wait
until the mac hine is turned off, unplugged and
all working parts have come to a complete
standstill.

Always wear ANSI-approved

safety glasses or goggles when operating
equipment.

12.3 Changing mode of operation

When changing the operating mode (planer to
jointer and back) the machine must be turned off,
unplugged, and come to a complete stand-still. To
change the mode of operation, see sect. 8.0, Jointer
Setup, and sect 9.0, Plan er Setu p on page 12.

4. Install new belt by first feeding the lower loop
downward behind the gear (H) a nd pulley (C).
This will properly position the lower loop of the
belt in close proximity to pulley (E).

5. Slide the top loop of the belt aro und and past
pulley (B), sliding it underneath and past chain
(G); then loop around pulley (F).

15

12.4 Jointer operations

Correct operating position

The operator must be positioned offset to the
infeed table (Figure 20).

Figure 20

Hand placement

Never pass hands directly over

the cutterhead.

Referring to Figure 21:
At the start of the cut, the left hand holds the

workpiece firmly against the infeed table and fence
while the right hand pushes the workpiece in a
smooth, even motion toward the cutterhead. After
the cut is under way, the new surface rests firmly
on the outfeed table. The left hand is transferred to
the outfeed side (Figure 21) and presses down on
this part of the workpiece, at the same time
maintaining flat contact with the fence. The right
hand presses the workpiece forward and before
the right hand reaches the cutterhead it should be
moved to the work on the outfeed table.

Figure 21

Direct ion of Grain

Avoid feeding work into the jointer against the grain
(Figure 22). This may result in chipped and
splintered edges.

Figure 22

Feed with the gra in to obtai n a smooth surfac e, as
shown in Figure 23.

Surfacing

The purpose of surfacing on a jointer is to produce
one flat surface (Figure 21). The other side can
then be milled to precise, final dimensions on a
thickness planer resulting in a board that is smooth
and flat on both sides and each side parallel to the
other.

 If the wood to be jointed is cupped or bowed,

place the concave side down, and take light
cuts until the surface is flat.

 Never surface pieces shorter than 12 inches or

thinner than 3/8 inch without the use of a
special work holding fixture.

 Never surface pieces thinner than 3 inches

without the use of a push block.

 Cuts of appro ximately 1/16" or less at a time

are recommended, which provides for better
control over the material being surfaced. More
passes can then be made to reach t he des ired
depth.

Figure 23

Edge Jointing

Jointing (or edging) is the process of creating a
finished, flat edge surface that is suitable for joinery
or finishing (Figure 24). It is also a necessary step
prior to ripping stock to width on a table saw.

 Never edge a board t hat is less t han 3 inches

wide, less than 1/4 inch thick, or 12 inches
long, without using a push block.

 W hen edging wood wider than 3 inches lap the

fingers over the top of the wood, extending
them back over the fence such that they will
act as a stop for the hands in the event of a
kickback.

When workpiece is twice the

length of the jointer infeed or o utfeed table use
an infeed or outfeed support.

16

To edge:

1. Make sure the fence is set to 90°. Double
check it with a square.

2. Inspect stock for soundness and grain
direction (refer to Direction of Grain on
previous page).

Several passes may be required to achieve full
bevel.

Figure 25

12.5 Planer operations

Figure 24

3. If the board is bowed (curved), place the
concave edge down on the infeed table.

4. Set the infeed table for a cut of approximately
1/16 inch.

5. Hold the stock firmly against the fence and
table, feed the stock slowly and evenly over
the cutterhead.

Beveling

Beveling an edge is the same operation as edge
jointing, except that the fence is tilted to a specified
angle.

 Make certain material being beveled is over 12

inches long, more than 1/4 inch thick and 1
inch wi de.

To bevel:

1. Use a bevel gauge to determine the desired
angle. Then set the fence to the same angle.

2. Inspect stock for soundness and grain
direction (refer to Direction of Grain on
previous page).

3. Set the infeed table for a cut of approximately
1/16.

4. If the board is bowed (curved), place the
concave edge down on the infeed table.

5. Feed the stock through the cutterhead, making
sure the face of the stock is completely flat
against the fence and the edge is m ak ing solid
contact on the infeed and outfeed tables
(Figure 25).

For wood wider than 3 inches – hold with
fingers close together near the top of the
stock, lappi ng over the board and ex tending
over the fence.

For wood less than 3 inches wide – use
beveled push blocks and apply pressure
toward the fence. Keep fingers near top of
push block.

Depth of Cut

Thickness planing refers to the sizing of lumber to a
desired thickness while creating a level surface
parallel to the opposite side of the board. Board
thickness t ha t t he p lane r will pr o d uce is indic a t e d by
the scale (see Table Height Adjustment on page

13). Preset the planer to the desired thickness of the
finished workpiece using the gauge. The depth-of­cut is adjusted by raising or lowering the planer table
(D, Figure 14) using the adjustable handle (C,
Figure 14).

 The quality of thickness planing depends on

the operator's judgment about the depth of cut.

 The depth of cut depends on the width,

hardness, dampness, grain direction and grai n
structure of the wood.

 The maximum thickness of wood that can be

removed in one pass is 5/64" for planing
operations on workpieces up to 5-1/2” wide.
The workpiece must be positioned away f rom
the center tab on the rollercase to cut 1/8”.

 The maximum thickness of wood that can be

removed in one pass is 1/16” for planing
operations on workpieces from 5-1/2” up to 8"
wide.

 For optimum planing performance, the depth

of cut shoul d be less than 1/16”.

 The board s hould be planed with shallow cuts

until the work has a level side. Once a level
surface has been created, flip t he lumber and
create parallel sides.

 Plane alternate sides until the desired thick-

ness is obtained. When half of the total cut has
been taken from each side, the board will have
a uniform, moisture content and additional
drying will not cause it to warp.

 The depth of cut should be shallower when the

workpiece is wider.

 When planing hardwood, take light cuts or

plane the wood in thin widths.

 Make a test cut with a test piece and verify the

thickness produced.

17

 Check the accuracy of the test cut before

working on the finished product.

Precautions

 A thickness planer is a precision wood-working

machine and should be used on quality lumber
only.

 Do not plane dirty boards; dirt and small

stones are abrasive and will wear out the
blade.

 Remove nails and staples. Use the planer to

cut wood only.

 Avoid knots. Heavily cross-grained wood

makes knots hard. Knots can come lose and
jam the blade. Any article that encounters
planer blades may be forcibly ejec ted from the
planer creating a risk of injury.

Preparing the Work

 A thickness planer works best when the

lumber has at least one flat surface. Use a
jointer to create a flat surface.

 Twisted or severely warped boards can jam

the planer. Rip the lumber in half to red uce the
magnitude of the warp.

 The work should be fed into the planer in the

same direction as the grain of the wood.
Sometimes the wood will change directions in
the middle of the board. In such cases, if
possible, cut the board in the middle so the
grain direction is correct.

Do not plane a board that is
less than 6" long. It is recommended that when
planing short boards you butt them end to e nd
to avoid kickback and reduce snipe.

Planing

1. Position the workpiece with the face to be
planed on top.

Note: Feed direction is left to right (see
Figure 12).

2. Turn the planer on.

3. Rest the board end on the infeed side of the
table and direct the board into the planer.

4. Slide the workpiece into the infeed side of the
planer until the infeed roller begi ns to advance
the workpiece.

5. Let go of the workpiece and allow the
automatic feed to advance the workpiece.

6. Do not push or pull on the workpiece. Move to
the rear and receive the planed lumber by
graspi ng it in the same manner that it wa s fed.

To avoid the risk of injury due
to kickbacks, do not sta nd directly in line wit h
the front or rear of the planer.

7. Do not grasp any portion of the board that has

not gone past the infeed roller.

8. Repeat this operation on all of the boards that

need to be the same thickness.

Avoiding Snip e

Snipe refers to a depression at either end of the
board caused by an uneven force on the
cutterhead when the work is entering or leaving the
planer.

Snipe will occur when the boards are not supported
properly or when only one feed roller i s in contact
with the work at the beginning or end of the cut.

Feeding the Work

The planer is supplied with planer blades mounted
in the cutterhead. Feed direction is left to right (see
Figure 12). The planer feed is automatic; it will vary
slightly depending on the type of wood.

Preparation:

 Feed rate refers to the rate at which the

lumber travels through the planer.

 The operator is responsible for aligning the

work so it will feed properly.

 Raise or lower the table to get the depth of cut

desired.

 The surface that the planer produces will be

smoother if a shallower depth of cut is used.

 Stand on the front side of the machine.
 Boards longer than 24” should have additio nal

support from free standing material stands.
These can be purchased f rom JET – Stock #

709209. See sect. 15.0, Optional Accessories.

Precauti ons for av oiding snipe:

 Push the board up while feeding the work until

the outfeed roller starts advancing it.

 Move to the rear and receive the planed board

by pushing it up when the infeed roller loses
contact with the board.

 When planing more than one board of the

same thickness, butt the boards together to
avoid snipe.

 Make shallow cuts. Snipe is more apparent

when deeper cuts are taken.

 Feed the work in the direction of the grain.

Work fed against the grain will have chipped,
splintered edges.

18

13.0 Maintenance

13.1 Blade Care

Blades are extremely sharp!

Use caution when cleaning or
changing. Failure to comply may cause serious
injury!



The condition of the blades will affect the
precision of the cut. Observe the q uality of the
cut that the machine produces to check the
condition of the blades.



Dull blades will tear, rat her than cut the wood
fibers and produce a fuzzy appearance.



Raised grain will occur when dull blades pound
on wood that has varying density. A raised
edge will also be produced where the blades
have been nicked.

When gum and pitch collect on the blades,
carefully remove with a strong solvent. Failure to
remove gum and pitch build up may result in
excessive friction, blade wear and overheating.

When blades become dull, they should be
replaced, or touched up – see sect. 13.2,
Sharpening the Knives.

4. Lay the stone on the infeed table.

5. Lower the infeed table and turn the cutterhead
by turning the cutterhead pulley. The infeed
table height is set properly when the stone's
surface is flush with the knife bevel.

6. Keep the c utterhead from rotating by grasping
the cutterhead pulley while sliding the stone
back and forth across the table.

7. Take the same amount of passes for all two
blades.

When the blades have been sharpened and still
are not cutting efficiently, trying to touch up the
blades further will only cause the formation of a
second beveled edge. When this starts to happen,
it is time to replace blades with another set. It is
recommended to keep a second set of blades o n
hand so that they may be installed while the first
set is being professionally sharpened.

13.2 Sharpening the Knives

Blades are extremely sharp!
Use caution when handling.

Failure to comply may cause serious injury!

1. Disconnect the machine from the power
source.

2. Remove the blade guard and belt cover.

3. To protect the infeed table from scratches,
partially cover the sharpening stone wit h paper
(Figure 26).
