When the TG1 assy or S-reel table is replaced, or when a part
constituting these parts is replaced, perform the following

• TG1 FWD Position Adjustment
• FWD Back-tension Adjustment (Refer to section 2-3-7.)

1. Adjustment procedure
1) Establish the [RP] mode.
2) Install the TG1 adjustment jig (Ref. No. J-20) as specified by
the S/T position setting.
Note: Be careful not to damage the flexible wiring board.
3) Attach the torque screwdriver (Ref. No. J-24) and the TG1 FWD
adjustment screwdriver (Ref. No. J-21) to the adjustment screw
block.
4) While rotating the adjustment screwdriver a little, press it down
lightly so that it is aligned with the gear of the (FWD)
adjustment plate.
5) Loosen the adjustment screw that is tentatively tightened by
the torque screwdriver. Perform adjustment so that TG1 comes
to the center of the gauge's groove when viewed from directly
above the TG1 adjustment jig (Ref. No. J-20). Then tighten
the adjustment screw.
Tightening torque: 0.0588 N•m (0.6 kg•cm).
