Electrical

Grounding Instructions

This jointer must be grounded while in use to

protect the operat or from electric shock.

The temporary adapter should onl y be used unti l a properly grounded outlet can be instal led by a qualified electrician. This adapter is not applicable in Canada. The green colored rigid ear, lug, or tab, extending from the adapter, must be connect ed to a permanent ground such as a properly grounded outlet box.

In the event of a malfunction or breakdown, grounding prov ides a path of least resistance f or electric current to reduce the risk of electric shock. This tool is equipped with an electric cord having an equipment-grounding conductor and a grounding plug. The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinanc es.

Do not modify the plug provided. If it will not fi t the outlet , have the proper outlet i nstalled by a qualified el ectrician. Improper connecti on of t he equipment-grounding conductor can result in a risk of electric shock. The conductor, with insulati on having an outer surface t hat is green with or without y ellow stripes, is the equipment grounding conductor . If r epair or r eplac ement of the electric cord or plug is necessary, do not connect the equi pment-groundi ng c onduc tor to a live terminal.

Check with a qualified electrician or service personnel if the grounding instructions are not completely understood, or if in doubt as to whether the tool i s properl y gr ounded. U se onl y three wire ex t ensi on c or ds t hat have three- pr ong grounding plugs and t hree-pole recept acles that accept the tool’s pl ug.

Repair or replace a damaged or worn cord immediately.

230 Volt Operation

Referring to Figur e 10: If 230V, single-phase operation is desired, the

following instr uc tions must be followed:

1. Disconnect the machine from the power source.

2. The Jointer motor has four numbered leads that are factory connected for 115V operation, as shown in (A). For 230V operation reconnect the leads as shown in (B).

3. The 115V attachm ent plug (C) supplied with the Woodworking Jointer must be replaced with a UL/CSA li sted plug suitable for 230V operation (D) . Contact your local Author ized JET Service Center or qualified electrician for proper procedures to install the plug. The Woodworking Joi nter must comply with all local and nati onal c odes after the 230-volt plug is installed.

4. The Woodworking Jointer with a 230-volt plug should only be connected to an outlet having the same configuration as shown in (D). No adapter is available nor should be used with the 230-volt plug.

115 Volt Operation

Referring to Figur e 9: As receiv ed f rom t he f actory , your W oodworking

Jointer is ready to run at 115-volt operation. This Woodworking J ointer, when wired for 115 volt, is intended for use on a circuit that has an outl et and a plug that look like the ones illustrated in (A). A temporary adapter, which looks like the adapter shown in (B), may be used to connect this plug to a two-pole receptacle if a properly grounded outlet is not av ailable.

Figure 10

Extension Cords

Make sure your extension cord is in good condition. W hen using an ex tension cord, be sure to use one heav y enough to carry the current your machine will draw. An undersized cord will cause a drop in the line voltage resulting in power loss and overheati ng. T able 1 sho ws the cor rect si ze to use depending on t he cord length and namepl ate ampere rating. If in doubt, use the next heavier gauge. Remember, the sm aller the gauge number, the heavier the cord.

5. Tighten locki ng handle (C, Fig 12). Important: When the tilted operation is finished and

the fence is returned t o 90°, do not forget to flip the 90° stop block (D, Fig. 12) back to its original position.

Fence Stop Adjustments

Periodically check the 90° and 45° backward (135°) tilt accuracy of the fence with an angle measuring device, such as an adju st able square or machinist’s protractor.

90º Fence Adjustment

Referring to Figur e 13: The 90º stop is control led by the st op bolt (E) and

the stop plat e (C).

1. Set the infeed t able to approx im ately t he sam e height as the outf eed table.

2. Move the fence by releasing lock handle (D) and pushing the fence assembly until it overlaps the tables (B).

3. Tighten lock handle (D).

4. Adjust the fence to a 90º angle by releasing lock handle (J), pulli ng up on the fence handle (A), and tightening the lock handle (J).

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

Figure 13

5. Place an angl e measuring dev ice on the t able and against the f ence to confirm a 90º setti ng (A, Fig. 14).

6. If the fence is not square to t he table, release the lock handle (J), loosen the hex nut (F), and turn the stop bolt (E) unt il the fence is square to the table.

7. Tighten the lock nut (F) to retain the setting. Tighten the lock handle (J).

45º Fence Backward Stop Adju stment

Referring to Figur e 15: The 45º fence backward stop (fence positioned

away from the operator) is controlled by the stop bolt (E).

1. Loosen the lock handle (A). Move the stop plate (D) out of t he way and position t he fence at the 135º angle. Make sure the fence sits against the stop bolt. ( E ).

Figure 16

Infeed Table Depth Stop

Referring to Figur e 17: The infeed tabl e depth stop (A) l imits the depth of

a cut (set by adjusti ng the infeed table handwheel) to a maximum depth of 1/8”. For normal operations, the depth of cut should never exceed 1/8", except f or rabbet ting operations.

If a rabbeting operation is desired:

1. Lower the infeed table to 1/8", which will cause the depth stop limiter to engage.

2. Loosen t he lock handl e (B) and pull out on t he stop handle (C).

3. Continue lowering the table to the desired depth of cut.

Important: Never override the depth stop limiter unless performing rabbeting operations.

Gib Adjustment

After a peri od of use, the gibs may become l oose and need adjusting.

To adjust (ref er t o Figure 18) :

Figure 17

1. Loosen setscrew locknuts (A) and gib lock screws (B).

Note: The infeed table has three gib adjustment screws A (Infeed). The outfeed table has two gib adjustment screws A (Outfeed) and two gib lock wing screws (B).

2. Tighten each setscrew 1/4 turn star ting at the bottom and working up. If a 1/4 turn does not remove all play, take anot her 1/ 4 turn. Repeat a 1/4 turn at a time for all three (or two) set screws until pl ay is rem ov ed.

3. Tighten wing screws (B) and lock nuts (A).

Important: If gibs are adjusted, also perform the Outfeed Table Adjustment to ensure the proper knife height in r elation to the outfeed table.

Figure 18

Setting Cutterhead Knives (JJ-6CSX)

Cutterhead knives are

dangerousl y sharp! Use extreme caution when inspecting, removing, sharpening or replacing knives into the cutterhead. Failure to comply may cause seriou s injury!

1. Carefully number each blade with a magic marker to make them easier to differentiate.

2. Rotate the cutterhead by turning the cutterhead pul ley and determ ine t he 12 o'cl ock position of knife number one. The 12 o'clock position i s the highest point a blade will r each in the cutting arc.

3. Loosen table lock screw (A, Fig. 19) and gib lock screw (B, Fig. 19) and rai se the outfeed table to the height of blade number one by turning hand wheel (A, Fig. 20). Counterclockwise will cause the outfeed table t o raise. Clockwise will cause the outfeed table to lower. Set a straight edge on the outfeed table. Posi tion of the table and straight edge should look like Figure 21. Use care when handling the str aight edge near the blades so as not to damage them.

4. When the outfeed tabl e and bl ade num ber one are the same hei ght, tighten gib and tabl e lock screws.

Important: Do not change the setting for the outfeed tabl e again. This will only change if the blades are replaced.

5. Bring the straight edge toward the left of the jointer and conf irm t hat blade num ber one is at the same height at the lef t of the t able as it is at the right side of the table. (Fig. 22)

Figure 19

Figure 20

6. If blade is higher or lower at the right of the table than it is at the left, slightly loosen four screws (A, Fig. 21) by turning clockwise as viewed from the infeed table. Blades are adjusted with jac ki ng screws To lower, tur n the screw clockwise. To raise, turn the screw counter-clockwise.

Blades are set at the proper height when the top of the blades are 1/16" above the cutterhead.

7. Alternately tighten four screws to hold each blade in place.

8. Repeat this process wit h blades two and three. The outfeed table and cutterhead knives are

correctly adjusted when all three blades are parallel to the outfeed table and all three blades are set at the same height in the cutterhead.

1. Disconnect machine from the power source.

2. Remove blade guard by turning the knob (A, Fig. 23) clockwise while lift ing up on blade guard.

Blades are sharp! Use great care when hands are around

blade area!

3. Loosen four screws (A, Fig. 24). Note: Loosen screws by t urni ng in a c loc kwise

direction as viewed from the infeed table. Carefully remove the knife (C, Fig. 24) and the

lock bar with screws (B, Fig. 24). Repeat for the other t wo blades.

4. Before assembly, clean all parts thoroughly and clear cutt erhead knife sl ots of any dust or debris.

Figure 23

5. Insert knife into the cutt erhead channel maki ng sure it faces the pr oper dir ec ti on.

6. Insert lock bar and screws and ti ghten to hold in place. Blades are set at the proper height when the top of the blade is 1/16" abov e the cutterhead. Do not ti ghten firmly at this time.

7. Repeat for other two blades.

Cutterhead Knives (JJ-6CSX) on page 16.

Figure 24

Outfeed Table Adjustmen t

When you receive the jointer, the knives have been pre-set at the factory. However, the height and paralleli sm of t he kniv es with t he outf eed tabl e should be checked, and any needed adjustments made, before putting the jointer into operation.

Adjust the height of t he outf eed table as follows:

1. Disconnect jointer from power source.

2. Carefully num ber each blade with a marker to make them easier to differentiate.

3. Place a straightedge upon the outfeed table and extend i t over the cutterhead (Figures 25 and 26).

Jointer kni ves are dangerously

sharp. Do not grab the cutterhead itself to ro tate it! Failure to comply may cause seriou s injury.

4. Rotate the cutterhead, using the drive belt or

pulley, until k nife number one is at it s highest point. The apex of the knife shoul d just barely come in contact with the straightedge.

If the apex of t he knif e number one j ust makes contact with the str aightedge, no adjustment is required f or the outfeed table. P roceed to the Setting Cutt er head K niv es section.

If the apex of the knife number one comes below the straightedge (a gap exists) or pushes the straightedge up, proceed with the following steps:

5. Loosen both gib lock screws (B, Fig. 18) and

the lock knob (Figure 25).

Figure 25

6. Raise or lower the outfeed table until the

straight edge cont acts the knife tip, as shown

in Figure 26. Using the drive belt or pulley, rock the cutterhead slightly to make sure the apex of the knife i s just barely contacting the straight edge.

When adjustment is complete:

7. Lock the outfeed table at that setting by

tightening the lock knob (Figure 25) and gib lock screws (B, Fig. 18). The outfeed table adjustment i s com plete.

The outfeed table adjustm ent is only made against one knife (blade number one was arbitrarily selected here). After the outfeed table has been set at the correct height, do not change it except for special operations or after replacing k niv es.

After this adj ustment is compl eted, it is necessary to proceed to the Setting Cutterhead Knives section to verify that all three knives are at the correct height and par allel to the outfeed table.

Figure 26

Setting Cutterhead Knives (JJ-6CSDX)

Note: Before setting knives for model JJ-6CSDX

Jointer, the Outfeed Table Adjustment should be done to ensure the proper k nife height in r elation to the outfeed table.

Knives for the JJ-6CSDX cutterhead are adjusted by means of a cam. It is important to note t hat the entire adjustment is accomplished within one complete r otation (360 degrees) of the cam. A full rotation of the cam will cause the knife blade to move a total of .015” from one extreme to the other. Turni ng the cam more t han one full rotation will not further adjust the knife setting, but will simply begin the adjustment all over again. The knife adjustment pr oc edure is outlined below.

Cutterhead knives are

dangerousl y sharp! Use extreme caution when inspecting, removing, sharpening or replacing knives into the cutterhead. Failure to comply may cause seriou s injury!

Figure 27

To adjust (ref er t o Figures 27 & 28):

1. Disconnect jointer from power source.

2. Carefully num ber each blade with a marker to

make them easier to differentiate.

3. Place a straightedge ac ross the outfeed tabl e

extending it over the cutterhead towards one end of the knife.

Cutterhead knives are

dangerousl y sharp. Do no t grab the cu tterhead itself to rotate it! Failure to comply may cause serious injury.

4. Rotate the cutter head back a nd for th using the

drive belt or pull ey, until knif e number one is at its highest poi nt. The apex of the knife should just barely come in contact with the straightedge.

5. Move the straightedge towards the other end

of the knife and repeat step 4. The apex of t he knife at bot h ends of the k nife

must just make contact with the straight edge. If the apex of the knife comes below the straightedge (a gap exists) or pushes the straightedge up, pr oc eed to the next step.

6. Using a 4mm hex wrench, slightly loosen the

four gib screws.

7. Using a 3mm hex wrench, loosen the cam

locking scre ws to per mit adjustment of the cam (described in t he next st ep) .

Important: Always keep the cam locking screws snug enough so that t he c am can’t

Figure 28

rotate freely. This is especially important for when the cam is rotated counterc lockwise since this acti on will cause the cam l ocking screw to loosen furt her.

8. Using an 8mm hex wrench, adjust the cam. This is a very sensitive adjustment. Start by rotating t he cam in a clockwise direc tion just a few degrees.

9. Next, keep the cutterhead steady by firmly holding on to t he pulley, place a piece of wood pressed against the knife’s edge and press to properly seat the blade.

10. Check your progress by repeati ng steps 4 and

5. If the knife becomes m ore out of adjustment, turn the cam in the other direc tion.

11. The adjustment is almost complete when the requirements described in Steps 4 and 5 are met.

12. Next, while pressing the k nife firml y against the cam, snug the t wo inside gib screws that hold the gib and knife in place. Verify that t he k nife is still in adjustment (steps 4 and 5).

13. Tighten the two outside gib screws, then the two inside gib screws. Verify that the knife is still in adjustment (steps 4 and 5).

14. Tighten the gib lock screws.

15. Repeat thi s entir e procedure for the rem aining two knives.

Replacing Knives (JJ-6CSDX)

Join ter knives are dangerously

sharp. Use extreme caution when inspecting, removing, or replacing knives.

To remove/r eplac e a knife (Refer to Figure 29):

1. Remove four gib screws (A) with a 4mm hex wrench.

2. Remove the gib ( B ) and knife (C). If the knif e is being reused (kniv es are double-

edged), clean t he knife, gib and cut terhead of all pitch and debris.

3. Lay the new knife or unused edge of the old knife back onto the cutterhead (D).

4. Replace the gib (B) and screws (A). Finger tighten only at t his tim e.

5. Press against the cutting edge of the knif e at the center of the blade with a piece of wood. DO NOT USE FINGERS! This is to ensure t hat the cam is making proper contact with the knife.

6. Snug the inside two screws, then the outside two screws.

7. Release the piece of wood pressing against the knife and tight en the gib screws.

8. Replace the rem aining two blades by repeating steps 1 – 7.

9. Determine if kniv es need to be set. Follow the Outfeed Table Adjustment section

steps 3 and 4 only t o determi ne if knives need to be set. Do not complete the entire outfeed table adjustment. If knives need to be set, proceed to the Setting Cutterhead

Knives section.

Figure 29

Setting Knives for Rabbeting and Nicks

(NOTE: Rabbeting is not applicable to the JJ6HHDX helical head jointer)

To position t he kniv es for rabbet cuts, take a shop scale with 1/32” graduations and place it against the end of t he c utterhead. Sli de the knife out until it is at the 1/32” m ark on the scale; t hat is, the knife will now be 1/32” beyond the edge of the cutterhead. The gib should remain in normal position, even with the edge of the cutterhead. (Figure 30). This adjustment will ensure that the knife clears the end of t he gib and cutterhead, and has good contact with the workpiece. (See the Rabbeting section for further information.)

Note: This will also corr ect for small nicks without requiring r eplac ement of knives.

Figure 30

Rotating and Replacing Knife Inserts (JJ-6HHDX)

Knife inserts are dangerously

sharp. Use extreme caution when inspecting, removing, or replacing knife inserts.

The knife inserts on the model JJ-6HHDX Jointer are four-sided. When dull, simply remove each insert, rot ate it 90° for a fresh edge, and r e-install it. No further adjustment is necessary.

Use the two provided star point screwdrivers to remove the knife insert screw. Use one of the screwdrivers to help hold the cutterhead in position, and the other to remove the screw. See Figure 30a. It is advisable to rotate all insert s at the same time to maintain consistent cutting. However, if one or m ore knif e inserts dev elops a nick , rotat e only those inserts t hat ar e aff ec ted.

Each knife insert has an etched r eferenc e mark so you can keep track of the rotations.

IMPORTANT: When removing or rotating inserts, clean saw dust fr om the screw, the insert, and the cutterhead platform. Dust accumulation between these element s can prev ent the i nsert f rom seati ng properly, and may affect the quality of the cut.

Before installi ng each screw, l ightly coat the screw threads with mac hine oil and wipe off any excess.

Determining Correct Table Height

The outfeed table and cutterhead knives are correctly adjusted when all three blades are parallel to the outfeed table and all three blades are set at the same height in the cutterhead.

Outfeed table t oo high – If the outfeed tabl e is too high, a curved finished surface results (Figure 31).

Outfeed table t oo low – If t he outfeed table i s too low, the work will have a gouge, or snipe, at the end of the cut (Figur e 32).

Outfeed table at correct setting – Figure 33 illustrat es the correct setting of outf eed table level with the knives. T he workpiece will rest firmly on

Operation

Important: Before operating the jointer, make sure all kni ves or knife inserts are seated and secure in the cutterhead.

If you are inexperienced at jointing, use scrap pieces of lum ber to check settings and get t he feel of operations befor e att em pting regular work.

Stabilize l ong workpieces by using an a ssistant, or roller stands set level with the outfeed or infeed table surface.

The fence should be adjusted to create minimum exposure to the cutterhead during the jointing operation.

10. Fence Tilt Lock Handle

11. Belt Guard

12. Fence Travel Loc k Handl e

13. Depth Limiter

Check the following before operating the joint er:



Outfeed table must be set level with the high point of the knives or k nif e inserts.



Fence adjusted for minimum exposure of cutterhead, and loc k ed at desir ed angle.



The cutterhead guard must be in place and operating properly (except when rabbeting) .



Infeed tabl e set for desi r ed depth of cut.



Stand away from the cutterhead and turn the machine on f or a f ew moments. Listen f or any odd noises, rubbings, vibrations, etc. Correct such problem s before at tempting oper ations on the jointer.



Carefully check your workpiece for knots, holes, staples or any foreign material that might damage kniv es or pose a risk of kic kback. Also check the workpiec e for grain orientation.

Hand Placement

Never pass hands d irectly over

the cutterhead .

At the start of the cut, the left hand holds the workpiece fi rmly agai nst t he infeed t able and f ence while the right hand pushes the workpiece in a smooth, even motion toward the cutterhead (Figure 34). After the cut is under way, the new surface rests firmly on the outf eed table. The left hand is transferred to the outfeed side 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 t he outf eed table.

Surfacing

Figure 34

Always use a hold down or

push block when surfaci ng stock.

Surfacing, or j ointing the f ace of stock, is shown i n Figure 35. A djust the inf eed table for depth of cut. Cuts of approximately 1/16” at a time are recommended, as this allows better control over the materi al being surf aced. More passes can then be made to reach the desired dept h.

Edge Jointing

Edge Jointing (Figure 36) is the most common operation f or the j ointer. S et fence square with the table. Depth of cut shoul d be the minimum required to obtain a straight edge. Do not make cut s deeper than 1/8" in a single pass. Hold the best face of the workpiece firmly against the fence throughout the feed.

Figure 35

Figure 36

Rabbeting

A rabbet is a groove cut al ong the edge of a board. See Figure 37. The width and thickness of the wood to be rabbeted depends upon t he width and length of the rabbet. However, never rabbet a piece of wood less than 12” l ong.

Note: The knives must be extended beyond the cutterhead by 1/32”. See the Setting Knives for Rabbeting and Nicks section on page 20 for this procedure.

A rabbet cut requires removal

of the guard. Use extreme caution and keep hands clear of cutterhead. Always re-install guard immediately after rabbeting operation is completed.

Use push blocks to rabbet cut whenev er possible. The rabbeting capacity is 1/2”.

1. Disconnect jointer from power source.

2. Set fence for desir ed width of rabbet.

3. Check width of the rabbet by measuring the

distance from the end of a knife in the cutterhead to the fence.

Figure 37

4. Re-connect power. It is easier and safer to

take a series of shal low cuts. Lower the i nfeed table 1/32” at a time and make successive cuts until the desired depth of rabbet has been obtained. See Figure 37.

Jointing Short or Thin Work

When jointing short or thin work pieces, use a push block to eliminate all danger to the hands. Two push blocks are shipped wit h your joint er. You can also make your own easily from scrap material. Examples are shown in Fi gur e 38.

Jointing Warped Surfaces

If the wood to be jointed i s cupped or bowed, place the concave si de down, and take li ght cuts until the surface is flat.

Avoid forci ng such materi al down against the tabl e – excessive pressure will spring it while passing the knives, and it will spring back and remain curved after the c ut is completed.

Figure 38

Beveling

To cut a bevel, lock the fence at the required angle and run the work piece across the knives while keeping it firmly against the fence and tables. Several passes m ay be necessary to achiev e the desired result.

Although the fence may be

tilted in or out for a bevel cut, it is recommended for safety reaso ns that the f ence be tilted in toward the operator, making a cradled cut.

Direction of Grain

Avoid feeding work into the jointer against the grain. This may result in chipped and splintered edges. See Figure 39. Feed with the grain to obtain a smooth surfac e, as shown in Figure 40.

Maintenance

Blade Care

Figure 39

Blades are extremely sharp!

Use caution when cleaning or changing. Failure to co mply may cau se serious injury!

When gum and pitch collect on the blades, carefully r emove with a strong solv ent. Failure t o remove gum and pitch build up may result in excessiv e fric ti on, blade wear and overheating.

When blades becom e dull, t ouch up blades. See Sharpening the Knives. NOTE: This does not appl y to the JJ-6CSDX or JJ-6HHDX models – knives or inserts must be rotated or replaced on these.

Sharpening the Knives (JJ-6CSX only)

Blades are extremely sharp! 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 guar d and belt cover.

3. To protect the infeed table from scratches,

partiall y cover the sharpeni ng stone with paper (Figure 41).

4. Lay the stone on the infeed t able.

5. Lower t he inf eed table and turn t he cutter head

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

Figure 40

Figure 41

6. Keep the cutterhead 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 three blades.

When the blades have been sharpened and still are not cutting ef ficiently, trying t o touch up the blades further will only cause the formation of a second beveled edge. When t his start s to hap pen, i t i s tim e to replace blades with another set. It is recommended to keep a second set of blades on hand so that they may be install ed while the fir st set is being professional ly sharpened.

Cutterhead Removal

The entire cutterhead assembly may be removed for cleaning or f or bearing and bl ade replacement. Some woodworkers keep a spare cutterhead with replacement blades should the origi nal cutterhead have to be repaired.

Blades in the cutterhead are

sharp! Use extreme caution when handling the removal of the cutterhead. Failure to compl y may cause seri ou s in ju ry!

To remove the cutterhead (including bearings, studs, and housing) from the base casting:

Referring to Figur e 42:

1. Disconnect the machine from the power

source.

2. Remove the front blade guard (A) and

screw (H).

3. Remove the lock handle (B), washer (C) and

lock nut (D) securing the fence assembly (E) to the table (F).

4. Lift the fenc e as s em bly (E) from the table.

5. From the left side of the stand, remove the

dust chute (G ). Fr om th e bac k of t he ma chi ne remove the cabinet ac c es s cover (not shown).

6. Using an 8mm hex wrench, loosen two hex

cap screws underneath fenc e base casting (E) that secure the casting to the table (F). Remove the fence base casting and set aside.

7. Remove four screws and washers (A) securing

the belt guard (B). Remove the belt guard.

8. Remove the V-belt (C) from the cutterhead

pulley (D). If necessary, loosen the motor mounting screws with a 12mm wrench to provide slack on the V- belt.

9. Using a 3mm hex wrench, loosen two set

screws that secure the cutterhead pulley (D) to the cutterhead shaf t. Set the pulley and shaft key aside.

Figure 42

Figure 43

10. Using a 14mm wrench, remove two screws

(A, Fig. 44) and lock washers that secure the cutterhead bearing housings to the base.

Note: These screws and lock washers are more easily accessibl e through the dust chute.

11. Carefully remove the cutter head ( A , Fi g. 45).

12. Before placing the new cutterhead back into

the casting, t horoughly clean the "saddle" and the bearing hou sings of saw dust and grease so that they seat properly.

Figure 44

13. T o re-install the cutt erhead, reverse the above

steps. Note: Make sure that the fence base cast ing is

level with the Outf eed t able when securi ng.

Lubrication



Use a good grade of li ght grease on the steel adjusting screws located in the raising and lowering mechanisms of the work tables.



Occasionally, apply a few drops of light machine oil to the infeed/outfeed gibs. This permits the tabl es t o sli de freely.

The cutterhead bal l beari ngs are lif etim e lubri cat ed and need no further care.
