BOSTITCH INSTALLATION ADJUSTMENT and MAINTENANCE MANUAL WARNING: MODELS S13A1, S13B2, S13C AND S13E S25A1, S25B2 AND S25C METAL STITCHERS % CROWN -NO. 18 WIRE NEVER OPERATE MACHINE WITH WIRE FEEDING AND NO MATERIAL ABOVE CLINCHER. SERIOUS DAMAGE MAY RESULT. EXCESSIVE AMOUNT OF LUBRICANT MAY BLEED CAUSING DAMAGE TO WORK BEING STITCHED. IN OPERATING A STITCHER, BE CAREFUL NOT TO DRIVE ONE STITCH OVER ANOTHER, AS THIS MAY BREAK THE DRIVER TIPS. DO NOT OPERATE THE STITCHER WITH WIRE FEED ON BUT WITHOUT MATERIAL BETWEEN DRIVER AND CLINCHER. IF A PIECE OF WIRE GETS CAUGHT IN THE GRIPPER OR FORMER OR SHOE, STOP THE MACHINE AND REMOVE CAREFULLY BEFORE ATTEMPTING TO STITCH AGAIN. 1. INTRODUCTION A wire stitcher, like any other machine, will give satisfactory results to its owner only if properly installed, regularly lubricated, intelligently adjusted, and carefully maintained. Moving parts will wear in time and require replacement, while others may break through accident. Trained service men are available but not always to be had at a moment's notice, and a knowledgeof thefunctionsof themore important parts of a stitcher is therefore most desirable for every person responsible for its operation, in order to know what to do in case of trouble. We have, therefore, gathered together the combined experience of our engineers and service men and have attempted to present the information in a manner that will make it quickly available and readily understood. We would urge, however, in any case of serious difficulty that you notify our nearest sales office, sending samples of the defective work and describing the trouble in detail, so as to obtain the benefit of their experience in arriving at the proper solution. Be sure to report the serial number and model of the machine when corresponding in regard to equipment, so that it may be identified quickly. 2. INSTALLATION (See charts and parts lists for locations and names of parts referred to.) Any machine can be seriously damaged during its installation if it is not properly set up; therefore, we recommend close adherence to the following procedure: (a) After uncrating machine, examine carefully for any breakage in transit. If such be found, do not attempt to run machine but report at once to the selling agent. If our service man is present, let him examine machine and then report to the manufacturer. (b) See that motor is free to revolve when large pulley or flywheel is turned by hand. If tight, clutch is perhaps engaged, in which case shaft will turn also. Turning pulley or flywheel one revolution will release clutch. (c) Examine name plate on motor and see that its specifications are the same as those of the power to be used. If not, do not attempt to operate the machine. (d) Place the machine on a level floor, using shims under base if necessary to prevent any movement or rocking. (e) Lower clincher to at least 2" below the stitcher head, by means of adjusting sleeve on post type stitcher, orclincherbracketadjustingscrewon head mounted clincher bracket stitcher or clincher arm adjusting screw or bolt on arm type stitcher. (f) Be sure that the machine isoiledthoroughlyat all points before operating. Run a little oil on coil of wire, which helps to lubricate wire feed tubes and also the formers and driver, which are tight-fitting when new. Tie a piece of cloth temporarily around the wire above the top end OT tne upper wire Teed tube to remove dirt and excess oil and thus prevent soiling the work. (g) Connect motor cord to power outlet and start motor. See that it runs freely, without undue noise,

and that the large pulley rotates clockwiseasviewed from the front of the machine. Should it rotate counter-clockwise, motor wiring should be reconnected by an electrician in order to reverse direction of rotation. (h) Push down foot switch treadle and thus start machine operating, starting and stopping several times. (i) Stop motor, and with connecting link arm pulled down, turn pulley by hand until driver is at lowest point. (j) With driver in lowest position and work to be stitched under same, raise clincher post, bracket, or arm, until work is held firmly. Then lock post, bracket, or arm, in position..(k) Place a spool of wire of proper size on the spoolholder, the wire leading to the left from top of spool, then tighten spool-holderspindlejam nut just enough to give a slight drag to the rotation of spool and prevent the wire uncoiling. If it is too tight, the wire will bind and catch between the coils and thus may cause uneven staple legs. If too loose, the spool may unwind, causing snags in the wire. Cut binding wires on wire coil and bend same back over edge of spool, holding free end of wire in the hand to prevent unwinding and tangling. Cut off bent and twisted end of the wire, then straighten out about 6". The end of the wire to be inserted in machine must be just as straight as possible. Open wire feed gears by raising idler feed gear throwout handle and insert end of wire through eye on upper end of the spring wire guide. Enter the end of the wire into the upper wire tube, push down between the wire feed gears, then through the lower wire tube and between wire straightener rolls. Push it into the hole in the stationary cutter, raising the end of the wire slightly if necessary for proper entrance, then turn down the idler feed gear throwout handle, thus engaging the feed gears. WARNING: NEVER OPERATE MACHINE WITH WIRE FEEDING AND NO MATERIAL ABOVE CLINCHER. SERIOUS DAMAGE MAY RESULT. (I) Start motor and drive a few stitches into material and, if necessary, adjust clincher height to get desired tightness of clinching. See instructions for adjusting clincher. (m) Adjust for proper length of wire by loosening lock screw and moving wire feed guard casting to rightor left along gauge marks on upper part of head casting. Moving to left reduces wire draw while moving to right increases it. When set at mark "0", head will draw one inch of wire and each mark indicates an additional 1 / 8 " in length. When proper length of wire is being drawn, tighten lock screw in place firmly. (n) Drive several rows of stitches into material to be used, examining crown and legs for proper appearance. If not satisfactory, adjust machine in accordance with directions given hereafter. NOTE: When changing length of wire draw, the first stitch driven, and perhaps the second, will beof the previously used length since it is formed from a piece of wire already cut and held in the anvil. The third stitch, however, will be of the new length. -2-3. ADJUSTMENT AND MAINTENANCE The following paragraphs cover briefly the various functions and operating parts of a stitcher and also give the proper methods of adjustment and replacement of parts. Every Stitcher should be oiled daily, and if machine is in constant use, twicedaily.theoil holes and cups are easily found on stitcher head and body. A heavier type of oil should be used for the former and drive bar. A light machine oil should be usedfor remainder of head. CAM LUBRICATING INSTRUCTIONS:-Trip clutch and rotate drive pulley manually, if necessary, in direction indicated by arrow on pulley until grease fitting on cam is aligned with hole in lubricating cover unit located in body or head casing. When fitting is visible thru hole in lubricating cover unit, lubricant can be applied with a grease gun to fit alemite hydraulic fitting (straight type). It is recommended that the cam be greased once monthly with Harris Moly-Lube #2 (high temperature) lubricant or equivalent. WARNING: EXCESSIVE AMOUNT OF LUBRI- CANT MAY BLEED CAUSING DAMAGE TO WORK BEING STITCHED. (a) Clutch Clutch should be oiled frequently with light machine oil. Never let clutch run dry. To oil, turn collar at end of shaft until oil hole is exposed. Put a few drops of oil into brake band occasionally. If the clutch hesitates on picking up, turn lower \ brake adjusting screw in or clockwise about 1 / 4 to V 2 turn, or until clutch picks up. If the clutch repeats, the lower brake adjusting screw should be backed out until clutch does not repeat. Be sure, however, that the BRAKE BAND IS FREE when the clutch is in operation or engaged. Clean out the Clutch Ring and Flywheel with kerosene or any cleaning solvent. It is not necessary to take the Clutch out. Squirt the cleaning fluid into the Flywheel and Clutch Ring and run the machine for a few moments, continuously starting and stopping. NOTE: Proper action of clutch and brake is as follows: When clutch engages, brake band should be free and when clutch is disengaged, brake band should be tight and clutch should be free. When clutch ring wears beyond point of contact, replace pins #2347 with pins #2347A. The following figures will identify expanding pins referred to: No. 2347 pin is.156" thick No. 2347A pin is.166" thick Thickness is determined by measuring the pin from the flat side to the opposite round side with a micrometer. NOTE: When replacing rings in clutch unit, the heads of the expanding pins for the brake ring and clutch ring must be facing each other. (b) Clincher The clincher must be lined up with the staple as

closely as possible to insure maximum ease of penetration through work by the staple, as well as to clinch staple properly. TO ADJUST CLINCHER SIDEWAYS ' V S13A1 and S25A1 Stitchers 1. Loosen post pivot cup clamp screws, and post brace lock nuts at post end. 2. Adjust post in direction desired, by means of post pivot cup adjusting screws. For example: To move post to the right, back out right hand screw and turn in left hand screw as much as necessary to locate clincher correctly. Turn in right hand screw until post is held solidly. 3. Tighten post pivot cup clamp screws and post brace lock nuts. S73C and S13E Stitchers 1. Loosen bottom nut on clincherarm adjusting bolt (on S13E only). 2. Loosen lock nuts on clincher arm side adjusting screws. 3. Adjust arm in direction desired by means of clincher arm side adjusting screws. For example: If arm must be moved to the right, back out the right hand screw and turn in the left hand screw as much as necessary. Turn in right hand screw until arm is held solidly. 4. Tighten lock nuts on clincher arm side adjusting screws. Tighten bottom nut on clincher arm adjusting bolt on S13E Stitcher only. I '! S25C Stitcher V_- j 1. Loosen arm adjusting screw set screw UA 5812.5. 2. Loosen arm clamp screws UA9160. 3. Adjust arm by means of arm adjusting screw UA8840.3. 4. Tighten rear clamp screw and check for correct position. Readjust if necessary. 5. Tighten both clamp screws securely.tighten arm adjusting set screw UA5812.5. TO ADJUST CLINCHER FORWARD OR BACK S13A1 and S25A1 Stitchers 1. Adjust post in direction desired by means of lock nuts at forward end of post brace. For example: -To move post forward, loosen nut at front of post and turn nut at back of post until desired position is reached. Then tighten nut at front end. S73C and S25C Stitchers 1. Loosen Clincher holder screws, push clincher forward or back to suit. Tighten clincher holder screws. S13E Stitcher 1. Loosen bottom nut on arm adjusting bolt and locknuts on arm side adjusting screws. Back out adjusting screws slightly. _? 2. Adjust arm in or out by turning arm pivot pin to right or left as required. 3. Return arm side adjusting screws to original setting and tighten lock nuts. 4. Adjust arm vertically, if necessary, by means of the two nuts on arm adjusting bolt. -3-5. Check adjustment of clincher operating slide by turning machine over by hand and watching clincher slide. If there is any tendency to bind, loosen lock nut under arm and back out set screw one or two turns. When'clincher cam has reached its maximum throwout position turn this screw in until clincher slide is flush with top of clincher. Tighten lock nut and turn over by hand again to be sure nothing binds. 6. Check all adjustments to be sure all are tight and try machine once or twice on scrap pieces of material. The arm should be adjusted so that the work will be just held between formers and clincher and should not deflect enough while the staple is being driven to cause loss of contact between formers and work. TO ADJUST ARM UP OR DOWN ON S25C 1. Loosen arm clamp screws UA9160. 2. Loosen lock nuts on arm elevating screw UA9076. 3. Tighten arm clamp screw lightly. Turn machine over by hand and check for space between clincher and bottom of formers. Turn arm elevating screw UA9076 in the required direction to obtain the space desired. Tighten clamp screws and arm elevating screw lock nuts secureiy. (c) Stitching Wire When stitching metal it has been found that #18 wire is best suited to the majority of work. This wire can be had in various degrees of hardness or temper, such as #18 Bookbinders wire, which is the softest, #18-230, #18-260, #18-290 and #18-330. It is impossibletogivethe exact thickness of metal which a given temper of wire will penetrate. Roughly, Bookbinders wire will penetrate a single thickness of.020 soft steel; #18-230, two thicknesses of.020 (total.040); #18-260, two thicknesses of.040 (total.080); #18-290, one thickness of.060 plus.030 (total.090); #18-330 two thicknesses of.060 (total.120). If the metal is too hard, there may be trouble in stitching so great a thickness; on the other hand, if the metal is soft, the thickness may be increased. When stitching a soft material like fibre or rubber to metal, especially if this material is thick, there may be trouble in penetrating the metal due to lack of support for the wire in the soft material. For this purpose, the #18-290 wire may help, in which case special spool holder equipment will be required. It is best to use the softest wire that will penetrate the work safely, as the harder wire will cause more wear on the machine. (d) WARNING: IN OPERATING A STITCHER, BE CAREFUL NOT OT DRIVE ONE STITCH OVER ANOTHER, AS THIS MAY BREAK THE DRIVER TIPS. DO NOT OPERATE THE STITCHER WITH WIRE FEED ON BUT WITHOUT MATERIAL BETWEEN DRIVER AND CLINCHER. IF A PIECE OF WIRE GETS CAUGHT IN THE GRIPPER OR FORMER OR SHOE, STOP THE MACHINE AND REMOVE CAREFULLY BEFORE ATTEMPTING TO STITCH AGAIN.
