Wind spring ( by turning lever IR- 1 56) when machine is not fastened to table. When spring is wound, tighten lever set screw temporarily. 3 Attach S hook (R-l60) bock to lever (R-156). 4 5 Adjust knee lifter to comfort of operator by loosening lever set screw When in desired position, tighten set screw ) securely. 6. With knee, press knee lifter to right to bring lever IR- 1 56) down to bottom of S hook lr-160). While in this position, loosen screw on stop bracket IR- 1 55A), bring stop firmly up to bottom of knee lifter bracket IR- 153) and tighten screw securely, If properly done, it should look like illustration. 7 IMPORTANT STEP: For the final operation, tap knee lifter R slightly to the LEFT. This little g ye shou d relieve tension of hook IR-l60) allowing it to play freely between feed frame 38) and lever (R 156). Keeping this slack is all important for proper operation. WHEN MACHINE IS WORKING, KNEE LIFTER R-l521 WILL NOT SWING BACK AND FORTH, IF PROPERLY ADJUSTED (At no time, should the operator s knee be in contact with the knee lifter when machine is in operation). 4

5 MOUNTING MACHINE Fasten machine to table using felt pad. Tighten screws evenly, turning each a little at a time. a. When an individual motor and clutch unit is employed, it is recommended that the motor be rated at 1 3 HP and RPM. On all standard models, use a 31/2 outside diameter pulley. On models intended for altera tion, use a 2 2 outside diameter pulley. b. When the machine is mounted on a power table, a 4 pulley should be used, If possible, when using such stands, the machine should be mounted TO AVOID CROSSING THE BELT. c. The maximum machine speed recommended for any installation is 3000 RPM, unless otherwise specified. 2. The handwheel s direction of rotation is away from the operator. It rotates in a clock-wke direction when looking at the face of the wheel pulley, as shown by the arrow. 3 Either V-belting or round leather belting may be used. Ex cessive tension of belt will cause over-heating and freezing of bearing at handwheel. 5

8 NEEDLE SETTING AND CHANGING THE MACHINE SHOULD BE CHECKED TO INSURE CORRECT NEEDLE SETTING TO PREVENT DAMAGE TO NEEDLES. 1 Depress knee lifter (R152). 2. Turn hand wheel CLOCKWISE until eye of needle is at slot in presser foot shoe (R49A) 3 Slowly release knee lifter the rib (R-612( should JUST 4 TOUCH THE NEEDLE. If rib is pressing up against needle (Fig. I (, turn dial (R-57N) toward LESS until rib just touches needle. 5 If rib is away from needle (Fig. 2), turn dial toward MORE until rib just touches needle, Ii \/ Fig. 1 Fig. 2 8

9 6. When needle just touches rib (Fig. 3>, machine is set to test. Fig. 3 7 To test machine, when ratio is set 2 to 1 ratio take single layer of mat ri :l, place in machine and turn machine by hand. If machine catches cnce, then does not catch on next stroke, machine is ready to work. 8. Keep dialing MORE or LESS until above results are obtained on silk or any thin goods. On heavy goods, it should catch on each stroke of needle You are now ready to thread machine. Refer to threading instructions. CHANGING NEEDLES If, after turning your dial several times, you experience difficulty in catching the lower layer of goods, examination may disclose a BENT or BURRED NEEDLE.. The needle should be changed immediately. IMPORTANT To test if needle is bent, needle must rest on needle guide R-47. To test if needle is burred, rub fingernail across point of needle. THE MACHINE SHOULD BE CHECKED TO INSURE CORRECT NEEDLE SETTING TO PREVENT DAMAGE TO NEEDLES. VERY IMPORTANT Use only genuine REX needles. Accept no others. REX needles cost no more than cheap imitations, and are ALWAYS available. Standard Size Needles: #10 - #15 - *20 - #25 - #30 Machines equipped with #25 9
