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 Planer-Jointer is designed and intended for use by properly trained 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 machine 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 shield while using this woodworking planer-jointer. Note: Everyday eyeglasses only have impact resistant lenses; they are not safety glasses.

7. Before operating this woodworking planer-jointer, remove tie, rings, watches, and other jewelry, and roll sleeves up past the elbows. Do not wear loose clothing. 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. Do not operate this machine while tired or under the influence of drugs, alcohol, or any medication.

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

11. Make certain the machine is properly grounded.

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

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

14. 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.

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

16. 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 moving parts, breakage of parts, mounting and any other conditions that may affect its operation. A guard or other part that is damaged should be properly repaired or replaced.

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

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

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

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

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

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

23. 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 more safely.

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

25. Maintain tools with care. Keep cutters sharp and clean for the best and safest performance. Follow instructions for lubricating, and changing accessories.

26. Make sure the workpiece is securely attached or clamped to the table. Never use your hand to hold the

workpiece.

27. Turn off the machine before cleaning. Use a brush or compressed air to remove chips or debris — do not use your hands.

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 the cutterhead 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.

Jointer Operation

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

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

33. Hands must never be closer than 3" to the cutterhead (see the Figure at right).

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 workpiece 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.

38. At all times hold the stock firmly against the table and fence.

Planer Operation

39. Keep hands outside the machine. NEVER reach under the guards to try to clear stock that stops feeding. Do not clear chips and sawdust with hands; use a brush. Do not have any part of the hands under that part of the board that is over the table when starting a cut; the infeed roll will engage the board and force it down against the table causing a pinching action.

40. Check stock condition. Do not plane boards with loose knots or with nails or any foreign material on its surface. Knife impact on these objects can cause the knives to be pulled out and cause them to shatter against the chipbreaker or pressure bar. Twisted, warped, or in wind stock should first be jointed on one surface before attempting to plane a parallel surface on the planer. Serious stock flaws cannot be removed by use of a planer alone.

41. To avoid kickbacks, use this machine for single board surfacing only. Never make cuts deeper than 5/32" (4mm).

Familiarize yourself with the following safety notices used in this manual:

This means that if precautions are not heeded, it may result in minor injury and/or possible

machine damage.

This means that if precautions are not heeded, it may result in serious injury or possibly even

death.

1. Loosen the tilt locking handle (F).

2. Flip the stop plate (I) out of the way.

3. Tilt the fence (A) back (E) to the desired angle, up to 135°. Or place a beveled reference piece on the table and against the fence, adjusting the fence until the fence angle matches the bevel of gauge piece.

4. Tighten the tilt locking handle (F).

10.0 Adjustments

10.1 Fence Stop Adjustments

Refer to Figure 9: Periodically check the 90° and 45° backward

(135°) tilt accuracy of the fence with an angle measuring device, such as an adjustable square or machinist’s protractor.

90° Stop Fence Adjustment

The 90º stop is controlled by the stop bolt (C) and the stop plate (D).

1. Set the infeed table (F, Fig. 7) to approximately the same height as the outfeed table (A, Fig. 7).

2. Move the fence (A) by releasing the

assembly locking handle (F) and pushing the fence assembly (E) until it overlaps the tables. Then, tighten the assembly locking handle (F).

3. Adjust the fence (A) to a 90º angle by releasing tilt locking handle (G), pulling the fence upright, and tightening the tilt locking handle.

Note: The stop bolt (C) should be resting against the stop plate (D).

4. Place an angle measuring device on the table and against the fence (A) to confirm a 90º setting.

5. If the fence (A) is not square to the table, release the tilt locking handle (G), loosen the lock nut (B), and turn the stop bolt (C) until the fence is square to the table.

6. Tighten the lock nut (B) to retain the setting. Tighten the tilt locking handle (G).

45° Backward Stop Fence Adjustment

The 45º fence backward stop (fence positioned away from the operator) is controlled by the backward stop bolt (H).

1. Set the infeed table (F, Fig. 7) to approximately the same height as the outfeed table (A, Fig. 7).

2. Move the fence (A) by releasing the

assembly locking handle (F) and pushing the fence assembly (E) until it overlaps the tables, then tighten the assembly locking handle (F).

3. Adjust the fence (A) to a 135° angle by releasing the tilt locking handle (G), moving the stop plate (D) out of the way, and positioning the fence against the backward stop bolt (H). Tighten the tilt locking handle (G).

4. Place an angle measuring device on the table and against the fence (A) to confirm a 135º setting.

5. To adjust, loosen the tilt locking handle (G) and lock nut (I), then turn the backward stop bolt (H) until a 135º angle is obtained.

6. Tighten the lock nut (I) to retain the setting. Tighten the tilt locking handle (G).

10.2 Table and Knife Adjustments

For accurate jointing, at least three things must be true:

1. Infeed and outfeed tables must be coplanar.

2. Knives or knife inserts must be set in the cutterhead so that the highest point of their arc is level with the outfeed table.

3. On the standard cutterhead, knives must be parallel with the outfeed table across the entire length of the knives.

These alignments are explained below.

10.3 Coplanar Alignment

Definition of Coplanar

When the infeed table is set to the same level as the outfeed table and all points on the tables lie in the same plane, thus forming a “perfect” flat surface, the tables are said to be coplanar.

For optimum performance of the jointer, the infeed and outfeed tables must be coplanar. If they are not, the finished workpiece may have a slight taper or twist across its jointed width or length.

Determining If Tables Are Coplanar

Refer to Figures 10 and 11: The tables have been set coplanar at the factory,

but they should be double-checked by the operator. Also, as the machine undergoes use, the tables should be checked occasionally and adjusted if necessary.

The procedure described below uses a steel straight edge to set the tables, which should be accurate enough for most purposes.

Figure 9

Important: The tables must be locked in position when performing the following test.

Disconnect machine from

power source before making any adjustments. Failure to comply may cause serious injury.

1. Disconnect machine from power source.

2. Fully swing the cutterhead guard (G) away from the fence (B). It is recommended to then

use a 6mm hex wrench (F) (one is included with the machine) as a makeshift stop to hold the guard in place. To do this, insert the wrench into the front right roller tension adjustment screw. The cutterhead guard can then be released and the wrench will prevent it from swinging back towards the fence.

3. Slide the fence assembly (B) back (C) as far as it will go, or remove it from the machine entirely (use a 5mm hex wrench to remove the four button head socket screws and then remove the fence assembly).

4. Loosen the outfeed table lock handle (C, Fig.

7) on the outfeed table (A). Use the outfeed table adjustment handle (B, Fig. 7) to raise the outfeed table higher than the cutterhead.

5. Place a straight edge (D) across the back of the outfeed table (A) and extending over the infeed table (E). Note the position of the infeed table. Note the position of the straight edge in Figure 10 with respect to the fence (B).

6. Raise the infeed table (A) until it contacts the straight edge (D).

The straight edge should lie level across both tables. Move the straight edge to the front of the outfeed table as shown in Figure 11 and perform the same test.

If the straight edge does not lie level, the front or back of one of the tables must be adjusted to make the tables coplanar. Proceed as described in Performing the Coplanar Alignment below.

Performing the Coplanar Alignment

Refer to Figure 12: If alignment is needed as determined in the

previous section, proceed with step 7. A 2.5mm hex wrench and a 22mm open wrench is required.

7. Each table has four adjustment cams; two in front (A) and two in back (D). A small hole with a set screw (C) inside is near each cam.

Note: The two cams at the front of each table are concealed by the front cover (B). The front cams furthest from the cutterhead can be accessed from below the cover, when the jointer table is raised and the machine is in the planer orientation (see sect. 9.1, Jointer to Planer Setup). If adjusting one of the front cams closest to the cutterhead, the front cover must first be removed to access the set screw. Use a cross-head screwdriver to remove the infeed table scale pointer, turn the infeed table lock handle (D, Fig.

7) and outfeed table lock handle (C, Fig. 7)

counterclockwise to remove them, and use a 5mm hex wrench to remove the four flat head socket screws along the top of the front cover; then remove the front cover.

Note: One cam at the back of each table is obscured by the jointer fence assembly. The cams can be accessed by removing the fence assembly, which can be done after removing four button head socket screws (B, Fig. 17) with a 5mm hex wrench.

Figure 10

Figure 11

8. Near the point of the table where the adjustment must be made, use a 2.5mm hex wrench to loosen the set screw (C) by turning it counterclockwise.

9. Turn the associated cam (A or D) with a 22mm open wrench. This adjustment is

sensitive and should be made in small increments.

Note: There is a notch on the cam that marks the

alignment of the cam’s eccentricity. There is a positive correlation between the mark and the infeed/outfeed table adjustment. When the cam is adjusted with the mark rotated upward, the corresponding area of the table is raised; conversely, when the mark is rotated downward, that part of the table is lowered.

10. Use the straight edge (D, Fig. 10 and 11) upon the tables to check the adjustment until the tables are coplanar.

11. When the adjustment is satisfactory and the tables now coplanar, tighten the set screw (C) with the 2.5mm hex wrench.

It may be necessary to repeat the exercise in this section more than once to achieve coplanar alignment.

Important: Before performing any adjustments in this section, the infeed and outfeed tables must be coplanar (see sect. 10.3, Coplanar Alignment).

Note: If the tables do not lock properly after the adjustment, see sect. 10.7, Jointer Table Lock Handle Adjustment.

Preparation

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

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

1. Disconnect machine from power source.

2. Fully swing the cutterhead guard (G, Fig. 11)

away from the fence (B, Fig. 11). It is recommended to then use a 6mm hex wrench (one is included with the machine) as a makeshift stop to hold the guard in place. To do this, insert the wrench into the front right roller tension adjustment screw. The cutterhead guard can then be released and the wrench will prevent it from swinging back towards the fence.

3. Remove the fence assembly (A, Fig. 17) and

upper back panel (C, Fig. 17) to access the cutterhead pulley (O, Fig. 19).

Figure 12

10.4 Setting Knives at Correct Height

and Parallel to Outfeed Table

Refer to Figures 13 - 17: For accurate jointing, the outfeed table surface

must be level with the knives (or knife inserts for the helical cutterhead) at the high point of their arc. In addition, on the straight cutterhead, the knives must be parallel with the outfeed table along the entire length of the knives.

When you receive the jointer, the knives have been pre-set at the factory. However, the height and parallelism of the knives with the outfeed table should be checked, and any needed adjustments made, before operating the jointer.

Height setting of knives is not applicable to the helical head model, in which the knife inserts are immediately at the proper height after installing. However, the height of the outfeed table must still be verified in relation to the arc of the knife inserts, as follows.

Setting the Outfeed Table Height

Use care when handling the straightedge near blades to prevent damage.

4. Place a straightedge (B) on the outfeed table

(A) near the back of the table. One end of the straightedge should be positioned over the cutting knife (E) near the end of the blade as shown in Figure 16.

Always rotate the cutterhead (D) via the cutterhead pulley (O, Fig. 19). Do not contact the cutterhead itself to rotate it.

5. Rotate the cutterhead (D) until one of the

blades is at its highest point in its cutting arc.

6. Loosen outfeed table lock handle (C, Fig. 7).

7. Use the outfeed table adjustment handle (B,

Fig. 7) to lower the outfeed table (A) until the straightedge (B) contacts the knife (E), as shown in Figure 13. Rock the cutterhead (D) slightly to make sure the apex of the knife is contacting the straightedge (B).

Figure 13

8. Lock the outfeed table (A) at that height by tightening the outfeed table lock handle (C, Fig. 7).

The outfeed table has now been locked at a standard height, level with the arc of the knife.

Note: After the outfeed table has been set at the correct height, it should not be changed except for special operations or after replacing knives.

On the helical cutterhead, after the outfeed table has been set, no further adjustments will be needed for the knife inserts. When inserts are installed properly in the helical cutterhead, they will automatically be set at the proper position.

On the straight knife cutterhead, further fine adjustments will now be achieved by adjusting the knives in the cutterhead. Proceed as follows.

Fine Knife Adjustment

9. Lower the infeed table (H) out of the way by loosening the infeed table locking handle (D, Fig. 7) and pushing down on the infeed table adjustment handle (E, Fig. 7).

10. An aluminum knife setting gauge, shown in Figure 14, is provided with the machine. Place the knife setting gauge at the back of the outfeed table (toward the fence support side) and extending over the cutterhead (D) as shown in Figure 14. Place the gauge so that the right mark lines up with the edge of the outfeed table, as shown.

11. Rotate the cutterhead clockwise. If the outfeed table and knives are set correctly, the knife will contact the gauge and move it until the left mark lines up with the edge of the outfeed table, as shown in Figure 15.

Figure 15

12. Place the knife gauge at the front of the outfeed table and repeat the process.

This test should be performed on the remaining knives using the provided gauge.

If any knife is either too high or too low at one of its ends to correctly move the gauge as described above, then the height and/or parallelism of that knife in the cutterhead needs to be adjusted. Proceed as follows.

13. Use a 13mm open wrench to slightly loosen the seven gib lock screws (F) by turning into the lock bar (G), clockwise as viewed from the infeed table (H).

14. Adjust the blade (E) height by turning the jack screws (C) upon which the blades rest with a 3mm hex wrench. To lower the blade, turn the screw clockwise. To raise the blade, turn the screw counterclockwise.

15. Use the edge of a board to push the knife (E) back down so that it is flush against the jack screws (C). Tighten the gib screws (F) only enough to keep the knife in position in the cutterhead. Do not fully tighten.

Figure 14

16. Check the height of the knife (E) again by using the gauge at the front and back of the outfeed table (A). Make further adjustments to the jack screw(s) (C) as needed.

Repeat this process for each of the other knives in turn. Do not fully tighten gib screws (F), only tighten them enough to keep the knife in position.

For best results, knives should be set at approximately .04" above the cutterhead. Knife height should not vary more than .002 - .003" across the length of the cutterhead. All three knives must be set at equal height in the cutterhead and parallel to the outfeed table across their length.

17. After all three knives are positioned properly in the cutterhead and made snug, continue tightening the gib screws (F). The gib screws should be tightened in increments, to prevent any distortion to the cutterhead or buckling of the knives. Begin tightening the gib screws a little more on one knife. Start with the center screw and work your way to the ends. Do not fully tighten yet.

18. Rotate the cutterhead to the other two knives in turn. Repeat step 17 for each knife.

19. The tightening process should continue at least two more times, each time tightening the gib screws (F) further on all three knives in turn. On the third time, the gib screws should all be firmly tightened.

Before operating the machine, make sure all gib screws are firmly tightened. A loose knife thrown from the cutterhead can cause severe or fatal injury.

20. After all knife adjustments are completed, the

upper back panel (C, Fig. 17) and the fence assembly (A, Fig. 17) should be placed back

on the machine before operating.

2. Fully swing the cutterhead guard (G, Fig. 11)

3. Turn all seven gib lock screws (F) into the

lock bar (G) by turning in a clockwise direction as viewed from the infeed table (H).

4. Carefully remove the cutter knife (E) and lock

bar (G).

5. Thoroughly clean all surfaces of the

cutterhead, knife slots, and lock bars of any dust or debris.

6. Insert the replacement knife (E) into the knife

slot, making sure it faces the proper direction.

7. Insert the lock bar (G) and tighten just enough to hold it in place.

Repeat steps 3 - 7 for the other two knives. The knives must now be adjusted as described in

sect. 10.4, Setting Knives at Correct Height and Parallel to Outfeed Table.

10.6 Replacing or Rotating Knife

Inserts (Helical Cutterhead Only)

Refer to Figure 18:

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

Cutterhead knives are dangerously sharp. Use extreme caution when inspecting, removing, sharpening, or replacing knives into the cutterhead. Failure to comply may cause serious injury.

The knife inserts on the model JPJ-12BHH are four-sided. When dull, simply remove each insert, rotate it 90° for a fresh edge, and re-install it.

Use the provided star point screwdriver to remove the knife insert screw. See Figure 18. It is advisable to rotate all inserts at the same time to maintain consistent cutting. However, if one or more knife inserts develops a nick, rotate only those inserts affected.

Each knife insert has an etched reference mark to keep track of the rotations.

An extra set of ten knife inserts and knife insert screws are included with your JPJ-12BHH.

Important: When removing or rotating inserts, clean saw dust from the screw, the insert, and the cutterhead platform. Dust accumulation between these elements can prevent the insert from seating properly, and may affect the quality of the cut.

Before installing each screw, lightly coat the screw threads with machine oil and wipe off any excess.

Securely tighten each screw which holds the knife inserts before operating the planer. Knife inserts should be torqued to approximately 50 to 55 pound-inches.

Make sure all knife insert screws are tightened securely. Loose inserts can be propelled at high speed from a rotating cutterhead, causing injury.

10.7 Jointer Table Lock Handle

Adjustment

Refer to Figure 19: For best performance, the jointer table lock

handles (C) should be approximately in the fully down position when in the locked position. If adjustment is required:

4. Use a gauge on the planer table to verify the height of the rollers in relation to the cutterhead.

5. When settings are correct, tighten the hex nuts (B) up against the casting.

Note: Replace upper back panel (C, Fig. 17) and jointer fence assembly (A, Fig. 17) if they were

removed to access the back ends of the rollers.

6. Make test cuts to verify the setting.

10.10 Feed Roller Pressure

Adjustment

Refer to Figure 23: The pressure of the feed rollers against the

workpiece during planing operations is maintained by spring tension. To adjust this tension, turn the socket head screw (A), clockwise to increase pressure or counterclockwise to decrease pressure.

Refer to Figure 23: The height of the infeed and outfeed rollers has

been set by the manufacturer for planing operations. If this setting should ever need adjustment, it is done using the screw (C) and nut (B) at each end of the rollers. Two 10mm open wrenches are required.

Note: The front ends of the rollers can be accessed when the jointer table is raised and the machine is in the planer orientation (see sect. 9.1, Jointer to Planer Setup). The back ends of the rollers can be accessed by taking off the jointer fence assembly (A, Fig. 17) with a 5mm hex wrench and the upper back panel (C, Fig. 17) with a 4mm hex wrench.

Figure 23

10.11 Planer Table Adjustment

Checking Planer Table Parallel to Cutterhead

Refer to Figures 24 and 25: The planer table is set parallel to the cutterhead

by the manufacturer and no further adjustment should be needed. If your machine is planing a taper, first check to see if the knives are properly adjusted in the cutterhead (see sect. 10.4, sect.

10.4, Setting Knives at Correct Height and Parallel to Outfeed Table) and make adjustments

if necessary. After the knives are confirmed to be properly set,

check to see if the work table is set parallel to the cutterhead as follows.

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

1. Disconnect machine from power source.

2. Rotate the cutterhead such that one of the

knives (A) is at the 6 o'clock position.

Figure 25

Adjusting Work Table Parallel to Cutterhead

Refer to Figure 26:

Figure 24

3. Place a gauge block (B) or another

measuring device on the work table (C) at one edge (D) directly under the cutterhead.

4. With the handwheel (F), gently raise the

table (C) until the gauge block (B) makes slight contact with the tip of the knife blade.

5. Move the gauge block (B) to opposite end of

table (E). If the distance from the table to tip of the knife

blade is the same at both ends, the table is parallel to the cutterhead.

If the work table is not parallel to the cutterhead, perform the adjustment procedure as follows:

6. Identify which side of the planer table (A) you intend to adjust: the front or back side.

7. With an 8mm hex wrench, loosen the two socket head cap screws along the edge the adjustment is being made: B1 and B2 if adjusting the front of the table, or C1 and C2 if adjusting the back.

8. Bring the table (A) parallel to the cutterhead by turning both the corresponding lead screws (D) by hand an equal amount.

Note: Turning the lead screw clockwise will increase the distance between the table and cutterhead. Turning the lead screw counterclockwise will decrease the distance.

9. Repeat steps 3 - 5 to determine if the planer table (A) is level with the cutterhead. If further adjustment is necessary, repeat steps 6 - 8.

When the table is determined to be parallel to the cutterhead, tighten the socket head cap screws (B1, B2, C1, C2).

Figure 26

11.0 Basic Operations

11.1 Dust Collection

Hand Placement

Never pass hands directly

over the cutterhead.

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 27) 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.

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

11.2 Initial Startup

After the assembly and adjustments are complete, the planer is ready to be tested. Turn on the power supply at the main panel. Press the start button. Keep your finger on the stop button in case of a problem. The planer 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 inves-

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

Always wear ANSI-approved

safety glasses or goggles when operating the planer-jointer.

11.3 Changing Mode of Operation

When changing the operating mode (planer to jointer and back), the machine must be turned off and at a complete standstill. To change the mode of operation, see sect. 9.1, Jointer to Planer

Setup and sect. 9.2, Planer to Jointer Setup.

Figure 27

Surfacing

The purpose of planing on a jointer is to produce one flat surface (Figure 28). 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" or

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

 Never surface pieces thinner than 3" without

the use of a push block.

 Cuts of approximately 1/16" at a time are

recommended, which provides for better control over the material being surfaced. More passes can then be made to reach the desired depth.

11.4 Jointer Operations

Correct Operating Position

The operator must be positioned offset to the infeed table (Figure 27).

Figure 28

Direction of Grain

Avoid feeding work into the jointer against the grain (Figure 29). This may result in chipped and splintered edges.

Figure 29

Feed with the grain to obtain a smooth surface, as shown in Figure 30.

To edge:

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

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

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".

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

Figure 31

Figure 30

Jointing

Jointing (or edging) is the process of creating a finished, flat edge surface that is suitable for joinery or finishing (Figure 31). It is also a necessary step prior to ripping stock to width on a table saw.

 Never edge a board that is less than 3" wide,

1/4" thick, or 12" long without using a push block.

 When edging wood wider than 3", 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.

 Position the fence (move it forward) to

expose only the amount of cutterhead required.

When workpiece is twice the

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

Beveling

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

 Make sure the material being beveled is more

than 12" long, 1/4" thick, and 1" wide.

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).

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 making solid contact on the infeed and outfeed tables (Figure 32).

For wood more than 3" wide – hold with fingers close together near the top of the stock, lapping over the board and extending over the fence.

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

Several passes may be required to achieve the full bevel.

Precautions

 A thickness planer is a precision

woodworking machine and should be used on good-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.

Figure 32

11.5 Planer Operations

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. The board thickness that the planer will produce is indicated by the scale and the depth-of-cut gauge (see sect. 9.4, Table Height Adjustment). Preset the planer to the desired thickness of the finished workpiece using the gauge. The depthof-cut is adjusted by raising or lowering the planer table (C, Fig. 5) using the handwheel (E, Fig. 5).

 The quality of thickness planing depends

upon the operator's judgment about the depth of cut.

 The depth of cut depends upon the width,

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

 For optimum planing performance, the depth

of cut should be less than 1/16".

 The board should be planed with shallow cuts

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

 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 ejected 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. Split the lumber in half to reduce 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 10" long. It is recommended that when planing short boards, you butt them end to end to avoid kickback and reduce snipe.

 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.

 Check the accuracy of the test cut before

working on the finished product.

Feeding the Work

The planer is supplied with planer blades mounted in the cutterhead, and infeed and outfeed rollers adjusted to the correct height. 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 planer 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 side of the machine that the

handle is attached.

 Boards longer than 24" should have

additional support via free standing material stands. These can be purchased from JET – Stock # 709209. See sect. 17.0, Optional Accessories.

Planing

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

Avoiding Snipe

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 is in contact with the work at the beginning or end of the cut.

Precautions for avoiding 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.

12.0 Maintenance

2. Turn the planer on.

3. Turn the power feed on.

4. Rest the board end on the infeed roller plate and direct the board into the planer.

5. Slide the workpiece into the infeed side of the planer until the infeed roller begins to advance the workpiece.

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

7. Do not push or pull on the workpiece. Move to the rear and receive the planed lumber by grasping it in the same manner that it was fed.

To avoid the risk of injury due to kickbacks, do not stand directly in line with the front or rear of the planer.

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

not gone past the outfeed roller.

9. Repeat this operation on all boards that need

to be the same thickness.

12.1 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 quality of the cut that the planer produces to check the condition of the blades.

 Dull blades will tear, rather 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 buildup may result in excessive friction, blade wear, and overheating.

When blades become dull, touch up blades. See sect. 12.2, Sharpening the Knives.

12.2 Sharpening the Knives (Straight

Knives Only)

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

Blades are extremely sharp! Use caution when handling. Failure to comply may cause serious injury!

1. Disconnect machine from power source.

2. Fully swing the cutterhead guard (G, Fig. 11)

3. To protect the infeed table from scratches,

partially cover the sharpening stone with paper (Figure 30).

4. Lay the stone on the infeed table.

7. Take the same number of passes for all three blades.

If 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 on hand so that they may be installed while the first set is being professionally sharpened.

Figure 30

Do NOT attempt to sharpen helical knife inserts! Only rotate the knife once it is dull. If all sides have been rotated properly, dispose of the knife and replace it with a replacement insert. Refer to sect. 10.6,

Replacing or Rotating Knife Inserts.

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

13.0 Lubrication

 Use a good grade of light grease on the steel

adjusting screws located in the raising and lowering mechanisms of the work tables.

The cutterhead ball bearings are lifetime lubricated and need no further care.

Trouble

Probable Cause

Remedy

Chain jumping.

Inadequate tension.

Adjust chain tension.

Sprockets misaligned.

Align sprockets. Sprockets worn.

Replace sprockets.

Machine will not start/ restart or repeatedly trips circuit breaker or blows fuses.

No incoming power.

Verify unit is connected to power, on-button is pushed in completely, and stop-button is disengaged.

Overload automatic reset has not reset.

When planer overloads on the circuit breaker built into the motor starter, it takes time for the machine to cool down before restart. Allow unit to adequately cool before attempting restart.

Planer frequently trips.

One cause of overloading trips, which are not electrical in nature, is too heavy a cut. The solution is to take a lighter cut. If too deep a cut is not the problem, then check the amp setting on the overload relay. Match the full load amps on the motor as noted on the motor plate. If the amp setting is correct, there is probably a loose electrical lead. Check amp setting on motor starter.

Building circuit breaker trips or fuse blows.

Verify that planer is on a circuit of correct size. If circuit size is correct, there is probably a loose electrical lead. Check amp setting on motor starter.

Loose electrical connections.

Go through all the electrical on the planer including motor connections, verifying the tightness of each. Look for any signs of electrical arcing which is a sure indicator of loose connections or circuit overload.

Motor starter failure.

Examine motor starter for burned or failed components. If damage is found, replace motor starter. If motor starter looks okay but is still suspect, you have two options: have a qualified electrician test the motor starter for function, or purchase a new starter and establish if that was the problem on changeout.

Switch or Motor failure – how to distinguish.

If you have access to a voltmeter, you can separate a starter failure from a motor failure by first, verifying incoming voltage at 220±20 and second, checking the voltage between starter and motor at 220±20. If incoming voltage is incorrect, you have a power supply problem. If voltage between starter and motor is incorrect, you have a starter problem. If voltage between starter and motor is correct, you have a motor problem.

Motor failure.

If electric motor is suspect, you have two options: Have a qualified electrician test the motor for function or remove the motor and take it to a quality electric motor repair shop and have it tested.

Miswiring of the unit.

Double check to confirm all electrical connections are correct and properly tight. The electrical connections other than the motor are pre-assembled and tested at the factory. Therefore, the motor connections should be double checked as the highest probability for error. If problems persist, double-check the factory wiring.
