–15–ASSEMBLY NOTES:1. Install the “PULLEY,RELAY DRUM(4G200) ” and the“STOPPER, BELT DRUM(4G300) ” to the “ASSY, LE-VER, PULLEY(4G100) ” with the “SPECIAL WAHSER-3X0.5(4G400) ”.Turn the raised side of the “STOPPER,BELT DRUM(4G300) ” toward the “PULLEY, DRUM(4F000) ” asshown in Fig. B of Fig. 3-7-2.2. Insert portion A into hole 1 and initially install the “ASSY,LEVER, PULLEY(4G100) ” using the “SCR S-TPG BIN2.6X3(4N000) ” as shown in Fig. A of Fig. 3-7-2.3. Referring to Fig. 3-7-3, adjust the pressure welding valueand install the “ASSY,LEVER,PULLEY(4G100) ” asfollows:a. Hook the “BELT, DRUM(4I000) ” and the “BELT,MOTOR STEP(4J000) ” on the gears, and tighten the“SPECIAL SCREW-2.6X8(4H000) ” and the “SCR S-TPG BIN 2.6X3(4N000) ” at the point where both beltsstretch tightly.b. Rotating the “PULLEY, DRUM(4F000) ” clockwise,rotate the “BELT, DRUM(4I000) ” more than onerevolution.c. Set the Ruler (VJ8-0228) along the “BELT,DRUM(4I000) ”, and confirm that the pressure welding valueis [1.34N±0.29N] when pressing the Dial TensionGauge DTN-150G (VJ8-0226) until play in the“BELT,DRUM(4I000) ” is 1mm. The measuring posi-tion and the direction of pressure are shown in Fig. 3-7-1.d. If the pressure welding value is not [1.34N±0.29N],loosen the “SPECIAL SCREW-2.6X8(4H000) ” andfine-adjust the “ASSY,LEVER,PULLEY(4G100) ”,then re-tighten the “SPECIAL SCREW-2.6X8(4H000) ”. Repeat steps b and c above until thepressure welding value is within [1.34N±0.29N].e. Referring to section 3-6, adjust the tension of the“BELT,MOTOR STEP(4J000) ”.PULLEY,DRUM(4F000)PULLEY,RELAY DRUM(4G200)BELT,MOTORSTEP(4J000)ASSY,MOTORSTEPPING(4K000)BELT,DRUM(4I000)Bending value 1mmPosition of measuring tensionBendingvalue 0.5mmFig. 3-7-1SCR S-TPG BIN2.6X3(4N000)ASSY,LEVER,PULLEY(4G100)SPECIAL SCREW-2.6X8(4H000)PULLEY,RELAYDRUM(4G200)STOPPER,BELTDRUM(4G300)SPECIALWAHSER-3X0.5(4G400)SPECIALWAHSER-3X0.5(4G400) BELT,MOTORSTEP(4J000)BELT,DRUM(4I000)Fig. AFig. BHole 1Portion ASTOPPER,BELTDRUM(4G300)Turn the raised side towardthe “PULLEY,DRUM(4F000)”.Fig. 3-7-2Dial tension gaugeDTN-150G(VJ8-0226)Ruler(VJ8-0228)ASSY,LEVER,PULLEY(4G100)SPECIAL SCREW-2.6X8(4H000)BELT,DRUM(4I000)PULLEY,DRUM(4F000)Fig. 3-7-3
