When the thread wiper solenoid plunger (1) is driven to the full stroke, the wiper (2) should be 15 mm in front of the needle center. Loosen screws (3) and shift the entire solenoid bracket (4)up or down to adjust. The standard height from the solenoid bracket (4) bottom to the needle plate top is approximately 112 mm. 2. When the wiper (2) is operated and aligned with the center of the needle bar, the distance from the wiper (2) to needle tip should be approximately 2 mm. Loosen screw (5) and move the wiper (2) in or out to adjust. As shown in Fig. A, make sure the wiper (2) does not strike the presser foot (6) or needle. Note Check that the wiper (2) is not touching the finger guard. 1261S 15mm - 16mm 35 mm 35 mm 25 mm 25 mm (3) (4) (6) (5) (1) (2) 1260S 1262S 1263S 1. Loosen the set screw (2) and move the wiper arm support (3) up or down to adjust so that there is a clearance of 15 16 mm between the bottom of the thread wiper and the tip (1) of the needle when the thread wiper is aligned with the center of the needle bar. 2. After the thread wiper has wiped the thread, loosen the bolt (5) and move the whole solenoid fixing plate (6) up or down to adjust so that the distance is approximately 25 mm. BAS-311F-0, 311F-L, 326F-0 9. STANDARD ADJUSTMENTS 9-10. Adjusting the two-step work clamp lift amount The maximum work clamp lift amount is 25 1 mm (for solenoid type) or 30 1 mm (for pneumatic type) from the top of the needle plate. The lift amount for each model is adjusted as shown in the table at the time of shipment. type Solenoid type (BAS-311F-0 only) Pneumatic type Lift amount 20 mm 9-10-1. BAS-311F-0 Solenoid type (3) (2) (1) 20 mm 1264S 1. Turn the power switch OFF. 2. Loosen the bolts (2) of work clamp arm lever F (1) . 3. Plase a scale against the work clamp (3), and then move work clamp arm lever F (1) up or down to adjust so that the amount of lift above the top of the needle plate is 20 mm. 4. After adjusting the lift amount (20 mm), tighten the bolts of work clamp arm lever F (1) . 9-10-2. BAS-311F-0, 311F-L Pneumatic type (1) (3) (2) (3) (2) (4) scale 20 mm (4) 1265S1266S1267S 1. Turn on the air, and then press the work clamp lifter switch (1) to raise the work clamp (2) . 2. Loosen the bolts (4) of work clamp arm lever F (3) . 3. Place a scale against the work clamp (2), and then move work clamp arm lever F (3) up and down to adjust so that the lift amount is 20 mm. 4. After adjusting the lift amount (20 mm), tighten the bolts (4) of work clamp arm lever F (3). BAS-311F-0, 311F-L, 326F-0 9. STANDARD ADJUSTMENTS 9-10-3.
