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 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 it s intended use. If used for ot her pu rposes, JET d isclaim s any rea l 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 jointer-planer. NOTE: Everyday eyeglasses only have impact resistant lenses; they are not safety glasses.

7. Before operating this woodworking jointer-planer, remove tie, rings, watches and other jewelry, and roll sleeves up past the elbows. D o not wear loose clothing. C onfine long hair. Non-slip footw ear 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, cement and oth er 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 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 a nd any other 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.

Page 5

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 the cutterhead or ot her 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 more safely.

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

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

27. Make sure the workpiece is sec urely attached or clamped to the table. Never use your hand to hold t he workpiece.

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

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

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

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

Jointer operation

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

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

34. The hands must never be closer than 3 i nches to the cutterhead (see Fi gur e at right).

35. Never app ly pressure to stock directly over the cutterhead. Thi s may result in the stock tipping into the cutterhead along with the operator's fingers. Position hands away f rom extreme ends of stock, and p ush through with a smooth, even motion. Never back workpiece toward the infeed table.

36. 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.

37. 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.

38. 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.

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

Planer ope r a t i on

40. Keep hands outside the machine. NEVER reach under the guards to try to clear stock that stops feeding. Do not cl ear chi ps and s awdust wit h hands; use a bru sh. Do not have any part of t he hands under that part of the board t hat is over the table when starting a cut; the inf eed roll will engage the board and forc e it down against t he table causing a pinching acti on.

41. Check stock conditi on. Do not pl ane boards with l oose knots or with nai ls or any f orei gn materi al on its surfac e. Knife impact on t hese objects can cau se the kniv es to be pulled out and cause them t o 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 parall el surf ac e on the planer. Serious stock flaws cannot be removed by use of a planer alone.

42. T o avoid kickbac ks, use this machine f or single board surfaci ng only. Never make cuts deeper t han 1/8 inch (3mm).

10.0 Adjustments

10.1 Table and knife adjustments

For accurat e jointi ng, at least thr ee thi ngs m ust 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 ar c 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.

Disconnect machine from power source b efore making any adjust ments. Failure to compl y may cause seri ou s injury.

10.2 Coplanar alignment

Definit io n of c op la na r

When the infeed tabl e is set to the same level as the outfeed tabl e and all points on the t ables lie in the same plane, thus forming a "perfect" flat surface, the t ables are said to be coplanar.

Figure 8

For optim um perform ance of the j ointer , the i nfeed and outfeed tables must be coplanar. If they are not, the fi nished workpiec e may have a slight taper or twist across its jointed width or length.

Determining if t abl es are coplanar

The tables hav e 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.

Important: The t ables must be locked i n position when performing the following test.

Refer to Figures 8 and 9:

1. Disconnect jointer from power source.

2. Loosen the lock knob (A) and slide the

cutterhead guard ( B , C) to clear the table.

3. Slide the fence assembly back (H, E) as far as

it will go, or remove it from the machine entirely.

4. Rotate the cutterhead to avoid knife

interference.

Figure 9

5. Place a st raight edge (D) ac ross the back of the outfeed table (F ) and ext ending over t he infeed table (G). Note the position of the infeed table

(G). Note the position of the straight edge in Figure 8 with respect to the fence (H).

6. Raise the infeed table (G) 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 tabl e as shown i n Fi gure 9 and perf orm t he same test .

If the straight edge does not lie level, the front or back of one of the tabl es must be adjusted t o make the tables coplanar. Proceed as described in Performing t he c oplanar alignm ent (following page).

Page 12

Performing the coplanar alignment

If alignment is required as determined in the previous section, proceed as follows:

Disconnect machine from

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

1. Disconnect power from machine.

2. Unlock both cabinet lock handles (A2,Fig. 10).

3. Raise the table (D) fully upright. Adjustment is performed by means of four

setscrews (B

) that adjust the t abl e pitch and ti lt at

the back (towards the fence) and two hex cap screws (A

) that adjust the table toward the fr ont.

Adjustment c an consist of a front adjust ment, rear adjustment or (more probable) a combination of both.

Rear adjustment

Tools requir ed – 13mm wrench, 4mm hex wrench

1. With a 13mm wrench, loosen three hex cap

10.3 Setting cutterhead knives

(straight knives only)

Important: Before perf orming any adj ustment s in

this section, the inf eed and outfeed tabl es must be coplanar (see sect . 10.2, Coplanar alignment).

Cutterhead knives are

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

1. Disconnect machine from the power source.

2. Remove the cutterhead guard (B, Fig. 8). Refer to Figures 11 and 12:

3. Car efully number each knife blade (C) with a

magic marker to differentiate each.

Note: Rotate the cutterhead via the cutterhead pulley. Rem ove the back panel of the cabinet for access.

4. Rotate the cutterhead (E) and determine the

12 o'clock position of knife number one. The 12 o'clock posi ti on i s the highe st poi nt a bl ade will reach in the c utti ng ar c (C, Fig. 12).

5. Set a straightedge (J) on t he outfeed table (F)

near the fence (H). One end of the straightedge should be positioned over the cutting knife (C) near the end of the blade as shown in Fig. 11.

Figure 11

Use care when handling the

straightedge near blades to prevent damage.

6. Note the position of the knife blade with

respect to the straightedge, then move the straightedge t o the other side of the t able and again note the posi tion of the k nife blade with respect to the straight-edge.

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

7. Slightly loosen five gib lock screws (A) by

turning into the lock bar (B), clockwise as viewed from the infeed table (G).

8. Adj ust the blade hei ght by turning jack screws

(D) upon which t he blades rest. To lower the blade, turn t he screw clockwise. T o raise, t urn the screw counter-cl oc k wise.

9. When the blade is at the proper height,

alternately tighten the five gib lock screws (A).

Repeat steps 4-9 for blades two and three.

sect. 10.3, Setting c utt er head k niv es .

10.5 Replacing or rotating knife

inserts (helical cutterhead only)

The knife inserts on the model J JP-12HH ar e foursided. When dull, simply remove each insert, rotate it 90° for a fresh edge, and re- install it.

Use the provided st ar point screwdriv er t o remove the knife insert screw. See Figure 13. It is advisable to r otate all inserts at t he same time t o maintain consistent cutting. However, if one or more knife inserts develops a nick, rotate only those inserts affected.

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

An extra set of 5 knife inserts and knife insert screws are included wit h y our J JP-12HH.

Figure 13

(Model JJP-12HH only)

IMPORTANT: When removing or rotating inserts, clean saw dust f rom the screw, the inser t, and the cutterhead platform. Dust accumulation between these element s can prevent the i nsert from seating properly, and m ay affect the quality of the cut.

Before instal ling each screw, lightl y coat the screw threads with mac hine 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 inchpounds.

Make sure all knife insert screws are tightened securely. Loose inserts can be propelled at high speed from a rotating cutterhead , cau sin g inju ry.

Page 17

10.9 Feed roller pressure adjustment

Refer to Figure 15. The pressure of the feed rollers against the

workpiece during pl aning operat ions is m aintained by spring tension. To adjust this tension, turn the socket head screw (B, Figure 15), clockwise to increase pressure, counterclockwise to decrease pressure.

10.10 Planer table adjustment

Disconnect machine from power source b efore making any adjust ments. Failure to compl y may cause seri ou s injury.

Checking Planer Tab le Parallel to Cutterhead

The planer tabl e is set parallel to the cutterhead by the manufact ur er and no further adjustment should be needed. If your m achine is plani ng a taper , fi rst check to see if the kniv es are properl y adjusted i n the cutter head (see sect. 10.3, Setting cutterhead knives) and make adjustments if necessary.

After t he knives are confirmed t o be properly set, check to see if the work tabl e is set paral lel to the cutterhead as follows.

1. Disconnect machine from power source.

2. Rotate the cutterhead such that one of the

knives (A, Fig. 16) is at the 6 o'clock position.

Refer to Figure 17:

3. Place a gauge block (B) or an other m easuri ng

device on the w ork table (C) at one edge (D) directly under the cutt er head.

4. Unlock the table loc k handle (F).

5. With the handwheel (G), gently raise the

table (C) until the gauge block (B) makes slight contact with the tip of the knife blade, then lock the tabl e.

Figure 16

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

table (E). If the di stance f r om the t abl e to ti p of t he knif e

blade is the same at both ends, the table is parallel to t he c utt er head.

Adjusting Work Table Parallel to Cutterhead

If the work tabl e is not parallel to the cut terhead, perform the adjustm ent procedure as follows:

7. With a 13mm wrench, loosen four hex cap

screws (H) located at each corner of the column support (J).

Figure 17

8. Bring the table parallel to the cutterhead by adjusting four setscrews (K) located at each corner of the column support (J) next to the hex cap screws (H).

9. Repeat steps 3 – 6, and i f further adjustment is necessary, repeat steps 8, 9.

When the table is determined to be parallel to the cutterhead, tighten the hex cap screws (H).

11.0 Basic operations

11.1 Dust collection

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 pr oblem. The planer should run smoot hly with l i ttle or no v i br ati on or rubbi ng noises. Investigate and correct the source of any problems bef or e further operation.

DO NOT attempt to inves-

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

in a smooth, even m otion t oward the cutt erhead. After the cut is under way, the new surf ace r ests firmly on the outfeed table. The left hand is transferred to the outfeed side (Figure 18) 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 tabl e.

Surfacing

The purpose of planing on a jointer is to produce one flat surf ace (Figure 19). The other side can then be milled to pr ecise, final dimensions on a thickness planer resulting in a board that is smooth and flat on both sides and each side parallel to t he other.

 If the wood to be jointed is cupped or

bowed, place the concave side down, and take light cuts unti l the surface is flat.

 Never surf ace pi eces shorter t han 12 inc hes

or thinner t han 3/8 inc h without the use of a special work holding fixture.

Always wear ANSI-approved

safety glasses or goggles when operating the jointer-pl aner.

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.

11.4 Jointer operations

Correct operating position

The operator must be positioned offset to the infeed table (Figure 18).

Figure 18

Hand placement

 Never surf ace pieces thinner than 3 inc hes

without the use of a push bloc k .

 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 m ade to r each the desired depth.

Figure 19

Never pass hands directly

over the cutterh ead.

At the start of the cut, the left hand holds the workpiece firmly against the infeed table and fence whil e the ri ght hand pushes the work piec e

Page 19

Direct ion of Grain

Avoid feeding work into the jointer against the grain (Figur e 20) . This may result in c hipped and splintered edges.

Figure 20

Feed with the grain to obtain a smooth surface, as shown in Figure 21.

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 ( r efer to Direction of grain).

Figure 22 – Surfac ing

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

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

5. Hol d the stock firmly agai nst the fence and table, feed t he stock slowly and evenly over the cutter head.

Figure 21

Jointing

Jointing (or edging) is the process of creati ng a finished, flat edge surface that is suitable for joinery or finishing (Figure 22). It is also a necessary step pri or to ri pping stock to width on a table saw.

 Never edge a board that is less than 3

inches wide, l ess than 1/4 i nch thick, or 12 inches long, without using a push block.

 When edgi ng wood wider than 3 i nches, 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 kickbac k.

 Position the fence (move it forward) to

expose only the amount of cutterhead required.

When workpiece is twice the

length of the jointe r inf e e d or out fe ed table use an infeed or outfeed support.

Beveling

Beveling an edge is t he same operati on as edge jointing, except that the fence is tilted to a specified angle.

 Make certai n material being bev eled is over

12 inches long, m ore than 1/ 4 inch thi ck and 1 inch wide.

To bevel:

1. Use a bev el gauge t o determine the desi red angle. Then set the f enc e to t he same angle.

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

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

4. If the board is bowed (curved), place the concave edge down on the i nfeed 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 tabl es (Figure 23).

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.

Page 20

For wood less than 3 inches wide – use

beveled push blocks and apply pressure toward the fence. Keep fingers near top of push block.

Several passes may be required to achiev e the full bevel.

 Plane alternat e sides until the desir ed thick-

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

 The depth of cut should be shallower when

the workpiece i s wider.

 When planing hardwood, take light cuts or

plane the wood in thin widths.

 Make a test cut wit h a test piece and verif y

the thickness produced.

 Check the accuracy of the test cut before

working on the finished product.

Figure 23 – Beveling

11.5 Planer operations

Depth of Cut

Thickness plani ng refers to the sizing of lum ber to a desired thickness while creating a level surface parallel to the opposite side of the board. Board thickness that the planer will produce is i ndi cated 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 dept h-of-cut is adj usted by raising or lowering the planer table (C, Fig. 5) using the handwheel (F, 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 struct ur e of t he wood.

 The maximum thickness of wood that can be

removed in one pass is 1/8” for planning operations on workpi eces up to 5-1/2” wide. The workpiece must be positioned away from the cent er tab on the roll ercase to cut 1/8”.

 A thickness planer is a precision

woodworking machine and should be used on good-qualit y lumber only.

Precautions

 Do not plane dirty boards; dirt and small

stones are abrasive and will wear out the blade.

 Remove nail s and staples. Use the pl aner to

cut wood only.

 Avoid knots. Heavily cross-grained wood

makes knots hard. K nots can come l ose and jam the blade. Any article that encounters planer blades may be forcibly ejected from the planer cr eating a risk of injury.

Preparing the Work

 A thickness planer works best when the

lumber has at l east one fl at surface. Use a jointer t o creat e a flat surf ac e.

 Twisted or sev erely warped boards ca n jam

the planer. Ri p the lumber i n 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 t he wood will change direct ions in the mi ddle of the board. I n such cases, if possible, c ut the board in the middle so the grain dir ection is correct.

 The maximum thickness of wood that can be

removed in one pass is 1/16” for planing operations on workpi eces from 5-1/2” up t o 12" wide.

 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 l evel si de. Once a level surface has been created, flip the lumber and create parallel sides.

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

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 autom atic; it will vary sli ghtly depending on the type of wood.

Page 21

Preparation:

 Feed rate refers to the rate at which the

lumber travels through the planer.

 The operator i s responsible for al igning the

work so it will feed pr operl y .

 Raise or lower the rollercase to get the

depth of cut desired.

 The surface t hat the planer pr oduces will be

smoother if a shall ower depth of cut is used.

 Stand on the side that the handle is

attached.

Avoiding Snipe

Snipe refer s to a depression at eit her end of the board caused by an uneven force on the cutterhead when t he work is ent ering or leav ing the planer.

Snipe will occur when the boards are not supported properl y or when only one feed rol ler is in contact with the work at the beginning or end of the cut.

Precauti ons for av oiding snipe:

 Push the board up while feeding the work

until the outfeed roller starts advancing it.

 Boards longer than 24” should have

additional support from free standing material stands. These can be purchased from JET – St ock # 709209. See sec t. 17.0, Optional access or ies .

Planing

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

2. Turn the planer on.

3. Turn the power feed on.

4. Rest t he board e nd on t he infeed roller pl ate 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 f eed to advance the workpiece.

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

 Move to the rear and receive the planed

board by pushing it up when the i nfeed 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. Sni pe is more apparent

when deeper cuts are taken.

 Feed the work i n the direction of the grain.

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

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

8. Do not gra sp any portion of the board that

has not gone past the outfeed roller.

9. Repeat this operation on all of the boards

that need to be the same thick ness.

Page 22

12.0 Maintenance

12.1 Blade care

Blades are extremely sh arp!

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 nic k ed.

When gum and pitch collect on the blades, carefully r emove with a strong solvent. Failur e to remove gum and pitch build up may result in excessiv e fric tion, blade wear and overheating.

6. Keep the cutterhead from rotating by grasping the cutterhead pulley while sliding the stone back and fort h across the table.

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

If the blades have been sharpene d and still are not cutting efficiently, trying to touch up the blades furt her will only c ause the formation of a second beveled edge. When this starts to happen, it is tim e to replace bl ades with another set. It i s 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 24

When blades become dull, touc h up blades. See sect. 12.2, Shar pening the Knives.

12.2 Sharpening knives (straight

knives only)

Blades are extremely sh arp! Use caution when handling.

Failure to compl y may cause seri ou s in ju ry!

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 with paper (Figur e 24).

4. Lay the stone on the infeed table.

5. Lower the infeed table and turn the cutterhead by t urning the cutter head pulley. The infeed t able height is set properl y when the stone's surface is flush with the knife bevel.

Do NOT attempt to sharpen helical knife inserts! Only rotate the knife once it i s dull. If all sides have b een rotated properl y, dispose of the knife and repl ace it with a replacement insert. Refer to sect. 10. 5,

Replacing or rotatin g knife inserts.

13.0 Lubrication



Use a good grade of light grease on the steel adjusti ng screws located i n the raising and lowering mechanisms of the work tables.

The cutterhead ball bearings are lifetime lubricated and need no f ur ther care.

Building cir c ui t breaker trips or fuse blows.

Loose electri c al connections.

Adjust chai n tension.

Align sprockets.

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

When planer overl oads on the ci r c uit breaker built into the motor starter, it takes tim e for the machine to cool down before restart. Allow unit to adequately cool before attempting restar t.

One cause of overl oading trips, which are not electri c al in nature, is too heavy a cut. The solution is to take a lighter cut. If too deep a cut is not the problem, t hen c hec k the am p setting on the overload relay. Match the full load amps on the motor as noted on the motor plat e. If the amp setting is correct then there is probably a loose electri c al lead. Check amp setting on motor starter.

Verify that planer is on a circuit of correct size. If circ uit size is correct, ther e is probably a loose electrical lead. Chec k amp setting on mot or start er .

Go through all the elec trical on the planer includi ng motor connections, v er ifying the tightness of each. Look for any signs of electric al ar ci ng whic h is a sure i ndicator of loose connections or circuit overload.

Motor starter failure.

Switch or Motor failure – how to distinguish.

Motor failure. If electric motor is suspect, you hav e two opti ons: Have a

Miswiring of the unit.

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 qualifi ed electrici an test the motor starter for functi on, or pur chase a new starter and establish if that was the problem on changeout

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, chec k ing 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, y ou hav e a starter pr oblem. If voltage between starter and motor is correct , you hav e a m otor pr oblem .

qualified electrician test the motor for func tion or remove the motor and take it to a quali ty elec tric motor repair shop and have it tested.

Double check t o confirm all electrical connecti ons are correct and properly ti ght. The electrical connections other t han the motor are pre-assembl ed and tested at the factory. Theref or e, t he motor connections should be double checked as the highest probabi lity for error. If problems persist, double-c hec k the factory wiring.
