9.0 Operating Instructions

9.1 Clamping material s in the vise

Refer to Figure 1.

1. Li ft th e saw arm to it s full up positi on.

2. Lock the arm up using the hydraulic feed control valve.

NOTE: Use the handle on the arm to lift the arm. Never use any other part of the arm as a lifting method.

3. Open the left vise by turning the vise handwheel counterclock wise.

4. Adjust the vise jaws for the appropriate cutting angle, if required. See sections on Right angle cutting and Angle cutting.

5. Put the work piece material between the vise jaws.

NOTE: If the work piece material is long, support both the ends of the material as needed to keep the material level on the saw base.

6. Turn the vise handwheel clockwise until the work piece is secu rely cla m ped in the vi se.

7. Proceed to cut according to instructions in Cutt ing procedur e.

9.2 Right angle cutting

Refer to Figures 1 and 8.

If you want to be certain the workpiece is being held in the vise at exactly 90 degrees to the blade for cutoff work, use the following procedure to check the bla de-to- jaw angle.

1. Disconnect the saw from its electric power source.

2. W ith the saw arm in its fully lowere d positio n, place a machinist's square,or a machinist's protractor 90 degrees, against the saw blade and rig ht vis e jaw. If the jaw is squa re to the blade, then no adjustment is required.

3. If adjustment is required, see Angle Cutting. The procedure for setting the jaw angle with respect to the blade is described in that section.

Figur e 8: Using a pr otractor to set the vise jaws at desir ed angle. By setting the pr otractor to 90 degrees, or using a machinist's sq uare, t he jaws can also be set square with res pect to t he blade.

4. Lift the saw arm to its full up position and lock it up using the hy draulic feed control kn ob.

NOTE: Use the handle on the arm to lift the arm. Never use any other part of the arm as a lifting method.

5. Loosen t he left jaw lock bol t.

6. Use the handwheel to move the left jaw until it touches the rig ht jaw firmly.

7. Snug the le ft ja w lock b olt. Bo th vise ja ws are now the correct angle for the required cut.

NOTE: There is a scale on the back of the saw tabl e w hi c h allows yo u t o set up f o r angle c u t s without using a protractor. See Figure 9. These angles should be considered approxi m ate, and th e protractor m ethod should be used where higher accuracy is r equired.

9.3 Angle cutting

Refer to Figure 8.

1. Loosen t he right jaw pivot and l ock bolts.

2. With the arm in its fully lowered position, and using a machinist's protractor between the saw blade and right vise jaw, set the angle of the ri ght jaw to the required an gle.

3. Ti ghten the pivot and lock bolts.

base to set the jaws for an gle sawing. Where t he edge of the right j aw crosses the scale an approxi mate angle cut c an be mad e to the indi cated number of degr ees o n the scale.

9.4 Clamping methods

The method for clamping different cross-section work pieces is sh own in Figure 10.

3. Slide the stock stop to the required distance from t he blade.

4. Rotate the stock stop so the stop is at the lowest possible position for stopping the work piece at the required distance. T his will he lp prevent any binding between the work piece and blade when the cut is completed.

5. Tighten the st ock stop set screw securel y.

6. F or be st accurac y, m ake a tes t c ut o n a piec e of scrap material to verify the length of cut using th e stock stop.

9.6 Blade selecti on

The saw is delivered with a blade adequate for a variety of jobs on a variety of common materials. However, JET's blades, while appropriate to many shop cutt ing needs, don't begin to exhaust th e w ide variety of special blades available for special cutting jobs.

For high production cutting of special materials, or for hard-to-cut materials such as stainless steel, tool steel, titanium, etc., ask your industrial distributor for more specific blade recommendations.

Figur e 10: Clamping methods for var ious crosssections of stock

9.5 Usi ng the st ock stop

When cutting a number of identical pieces, the use of th e stock stop can speed operation s.

Refer to Figures 1 and 11.

1. Disconnect the saw from its electric power source.

9.10 Usi ng the hydrauli c f eed cont rol

Refer to Figure 15.

The hydraulic feed control cylinder is a "single action" hydraulic cylinder. This allows you to lift the arm at any time, easily, but controls the do wnward m ovem ent of the arm us ing a valve on the top of the cylin der.

Figur e 14: Setting correct pl ay in drive belt

7. Tighten the adj ustment lock nut .

8. Close the pulley cover and secure it shut with the lock screw.

9. Reestablish electrical power to the saw and proceed with cutti ng.

9.8 Evaluating cut ting effici ency

Is the b lad e cutting e ff ic ie ntly? T he bes t way to te ll is by observing the chips formed by the blade as it cuts.

If the chip formation is powdery, then the feed is much too ligh t or the blade is t oo dull.

If the chips formed are curled, but straw or blue color ed, then the feed rate i s too hi gh.

Figur e 15: Hydraul ic feed cont rol

When the control valve is turned fully clockwise the cylinder is "locked" and the saw arm will not move do wnw ar d . You can l o c k the ar m , us ing the val ve , at any pos itio n i n its tr avel. T h is allo ws yo u to lo c k the arm in its up position for operations which require it. And it allows you to lock the arm in positions which allow you to adjust work piece length, etc.

Most important, use of the valve allows you to begin any cuts "gently," which can greatly extend the life of the blade. Simply open the valve slightly to begin the cut, then open the valve to effective cutting feed. See Evaluatin g cuttin g efficiency.

The valve is also important when breaking in any new blades. See Blade br eak-in pr ocedures.

9.11 Bl ade break-in procedures

New blades are very sharp, and therefore have a toot h geometry which is easily damaged if a car eful break-in procedure is not followed. You may want to consult manufacturers' literature for break-in of sp ecif ic b lades on speci f i c m ate r ial s . Ho wever, the following break-in procedure will be adequate for break- in of JET supplied blades.

1. Clam p a 2 inch or la rger work pi ece in the saw.

2. Set the blade speed to its required speed. See Changing blade sp eeds.

3. If possible, use a cutting fluid during break-in cuts.

4. Set the hydraulic control valve just enough to begin a ver y light cut on the work pi ece.

5. When the blade has cut 1/3rd of the way through the work piece, increase the feed rate slightly and allow the blade to complete the cut.

6. Make another cut on the stock. Begin the cut with the c o ntro l valve s e t at the s am e feed rate yo u fi ni s hed the fi rst cut.

7. 1/3rd of the way through the second cut, increase the rate of feed until the blade is cutting at its most efficient rate. See Evaluating cutting efficiency.

8. Allow the saw to complete this second cut. The blade can now be considered ready for regular service.

Note: There are flanges on the back face of the drive and idler wheels to prevent the blade from "walking off" the back of the wheels. If these fla nges are damaged the wh eels must be replaced. Check blade tracking whenever changing a blade to be certain the blade is positioned correctly on the wheels. See Bl ade tracking in the Maintenance secti on of thi s m anua l

9.12 Changing blades

1. Disconnect the saw from its electric power source.

2. Lift the saw arm to its full up position and lock it up using the hy draulic feed control kn ob.

6. Examine the drive and idler wheels for evidence of wear on the flanges. If the flanges are wearing, the blade is misadjusted. See Blade t racking for correcting this condition.

7. Put a replacement blade in the blade guide bearings and loop the ends of the blade over the drive and idler wh eels.

NOTE: The saw blade teeth must point in the dir ection of travel. See Figure 16.

8. Use the blade tension knob to put tension on the bla de until it no l onger slips on the wheels.

NOTE: Do not overtighten the blade. Just increase tension until the blade does not slip on the wheels.

9. Close the blade guard cover and replace and ti ghten the th umb scr ew.

10. Reconnect the saw to its electrical power source.

Figure 16: Corrrect tooth direction when replacing blade.

9.13 Ad j ustin g b lade guides

Refer to Figure 1. Both the left and right blade guides should be

positioned as close as possible to the left and right edges of any work piece being cut. This provides support t o the bl ade so it can make a strai ght cut.

1. Loosen the bl ade gu ide knobs.

2. Slide t he blade guides to the correct spaci ng.

3. Tighten the lock knobs securely.

10.0 Maintenance

NOTE: The following maintenance operation requi res the servi ces of a licen sed electri cian.

NOTE: Use the handle on the arm to lift the arm. Ne ver us e any ot he r part o f t he arm as a lifting method.

3. Remove the blade guard cover thumb screw and open the cover.

4. Loosen the blade tension knob until the blade come s off of its wheels.

5. Using leather gloves to protect from cuts, slip the blade out of the blade guide bearings and off o f the saw.

10.1 Motor replacement

1. Perform steps 2 through 5 in Changing blade speeds, sect. 9. 7.

2. Remove t he drive belt.

3. Remove the set screw which retains the motor drive pulley to the motor shaft.

4. Pull the pulley off o f the motor dr ive shaft .

5. BEING CERTAIN THAT THE SAW HAS BEEN SAFELY DISCONNECTED FROM THE SERVICE BRANCH, open the motor terminal

cover and remove the three wires which connect i t to th e power cable.

6. Remove the four nuts, bolts and washers which hold the motor to its mounting plate.

7. Remove the motor from the saw.

8. Reinstall the replacement motor and pulley by reversing steps 7 thr ough 4, above.

9. Loosen the motor mounting plate adjustment screw so the screw puts no tension on the plate.

10. Adjust the position of the motor so th at: A. t he pu lleys a re parallel with ea ch other, and B. the drive belt can just be installed over the

pulleys (It may be necessary to adjust the drive pulley along the motor shaft to make the pul leys par allel.)

11. Tighten the motor mounting bolts securely.

12. Tighten the pull ey set screw securel y.

13. In stall the drive belt.

14. Tension the drive belt and complete the replacement task by performing instructions 6 throu gh 9 in Changing bla de speeds.

10.2 Ad j ustin g g ui de bearings

The outside guide bearing on each of the bearing seats is mounted on an eccentric shaft to allow adjustment of the bearing clearance between bearin gs an d blade, as follows:

4. Remove the thumb screw and open the blade guard cover. Prop it open so you can have access to the idler wheel.

5. Refer to Figure 17. Use a wrench to loosen bolt A, a small amount.

Figur e 17: Blade t racking mechanism

6. Turn the saw motor ON.

7. I nsert a hex wrench into the set screw, B, and turn it slightly while observing the tracking action of the blade on the idler wheel. Turning

the hex wrench clockwise will make the blade track toward the wheel flange. Turning the wrench counterclockwise will make the blade tr ack away from the flange.

8. Adjust the set screw in very small amounts until the blade just starts to track toward the flange.

9. As you adjust the blade toward the flange, insert a strip of paper between the blade and wheel as shown in Figure 18.

1. Loosen the guide bearing shaft l ock nut.

2. Use an open end wrench on the hex flats underneath the guide seat to adjust the eccentric shaft so the bearing holds the blade vertically against its opposing bearing. Overtightening the blade between the bearings will only shorten bearing life. Adjust the bearings so blade is just held firmly in vertical position.

3. While holding the shaft from turning, tighten the lock nut on the upper side of the bearing seat.

10.3 Bl ad e t racking

1. If the blade is fully tensioned, release tension slightly while performing the tracking operation.

2. If the blade is not on slow speed, change to the slowest speed according to instructions in Changing blade s peeds.

3. Lift the saw arm to its full up position and lock it using the hydraulic feed control knob.

NOTE: Use the handle on the arm to lift the arm. Ne ver us e any ot he r part o f t he arm as a lifting method.

Use a strip of paper six

inches long or longer so your hands stay clear of the m oving parts of the saw.

Figur e 18: Checking bla de trac king

10. Keep using small amounts of adjustment to move the blade toward the flange, testing with the paper strips, until the paper is cut between the bla de and flange.

11. When the paper is cut, turn the hex wrench slightly in the opposite direction so the blade

does not t rack w hil e touching the flange.

12. Tighten bolt A.

13. Check with a paper strip to be certain the blade has not moved back into contact with the flange. Readjust, if necessary.

14. Using the blade tension knob, reapply tension to t he blade so it does not slip on the wheels.

15. Turn the saw OFF.

16. Close the blade guard cover and install and ti ghten the th umb scr ew.

10.6 Ad j ustin g the arm stop

adjustment bolt

Refer to Figure 1.

1. Lower the arm to its fully lowered position. The saw blade should be level and the cutting edge of the blade should be in the relief slot,

below the leve l surf ace of the s aw base . If this is not the case, adjust the arm height as follows:

10.4 Rep lacing guide b earings

1. Remove the blade according to instructions 1 throu gh 5 in Changing bla d es, sect. 9.12.

2. Remo ve t he snap ri ng wh i c h ho l d s the b e ar ing to the shaft.

3. Press off th e bearing.

4. Press on the new bearing and secure it with the snap ring.

5. Reinstall the blade according to instructions 6 throu gh 10 in Chang ing blad es.

6. Adjust the bearing spacing according to instructions in Adjusting gu ide be ari ngs.

10.5 Ad j ustin g b ack- up bearings

1. Disconnect the saw from its electrical power source.

2. Loosen the guide bearing seat reta ining bolt.

3. Slide the bearing seat as necessary until the back-up bearing just touches the back edge of the saw blade.

2. Loosen the leveling bolt lock nut.

3. Adjust the leveling bolt until it supports the arm and blade correctly as described above -- level and below the t op of the saw base.

4. Tighten t he levelin g bolt lock nut.

10.7 Ad j ustin g mo t or swit ch actuator

This task should be performed whenever the arm stop adjustment is corrected or whenever the saw is turning off incorrectly.

Refer to Figure 1.

1. Rai s e the ar m unti l the switc h ac t u ator is not in contact with the switch.

2. Turn the switch ON.

3. Open the hydraulic control valve so the arm moves slowly downward.

4. The motor switch should shut off just as the arm contacts its horizontal stop bolt and the blade is fully below the blade relief in the saw base. If the motor shuts off too soon, or not at all, adj us t t he swit c h act u ator by bendi ng i t , as required, to correct the faul t condit ion.

4. Tighten t he guide beari ng seat reta ining bolt.

5. Restore elect rical power to the saw.

seats fo r blade vertical

1. I nstall a new blade according to instructions in sect. 9.12.

2. Adjust the guide bearings according to instructions in sect. 10.2, Adjusting guide

bearings.

1. With the bar stock securely clamped in the vise, make a cut through the bar stock. (See

Figur e 21.)

3. Adjust the back-up bearing according to instructions in sect. 10.5, Adjusting back-up

bearings.

4. With the arm in its full horizontal position and the blade guides moved apart to clear the widest possible cutting area, clip a scale to the blade, to provide a vertical reference surfa ce.

5. Place a machinist's square on the saw base, against the scale. See Figure 20.

Figur e 20: Adjust ing the saw bla de for vert ical. Be sure t o do this oper ation on both of the bearing guide seat s so the blade is per fectly vertical along its entire exposed cutting surface.

2. Mar k the top of the bar stock.

3. Move the bar stock about 1/4 inch past the blade so you can begin a second cu t.

4. Rotate the bar stock 180 degrees so the mark you made is now at the bot tom of the cut .

5. Make a cut through the bar st ock.

6. Use a micrometer to measure the thickness variation between the top and bottom of the disc you have cut from the bar stock. Unless things are truly perfectly aligned, there is almost certain to be a certain amount of "wedge" to the shape of the disc you have cut. The saw blade can be considered correctly adjusted when the variation measured is no more than .012 inch across the face of the
