1. General The Pfatf 145 is a special-purpose sewing machine equipped with unison feed, smoothly working sleeve take-up and vertical rotary hook, which sews forward and backward. It is chiefly used for sewing multiple plies where it is important that all finish out evenly.
3. Cleaning and Oiling Careful cleaning and regu’ar oiling will increase the service life of your machine. After you have removed the dust which has accumulated on the machine in transit, take a clean rag and remove the grease from all nickel-plated and polished parts.
From time to time remove the needle plate after taking out set screws 1 and 2 (Fig. 4) and remove the lint which has accumulated underneath. The cleaning of the hook is dis cussed in Chapter 13.
4. Winding the Bobbin Place a spool of thread on pin 1 (Fig. 5) and pass the thread from left to right through eyelet 2, clockwise around and between tension discs 3 and from the inside through the slot in the bobbin. Wind a few turns of thread on the bobbin and place the latter on spindle 4.
5. Changing the Bobbin and Threading the Bobbin Case Raise the needle to its highest position and open the bed slide. With the thumb of your right hand open latch B (Fig. 6), then push the thumb nail under the projecting flange C of the bobbin case cap and lift the latter out of the machine with thumb and fore finger.
6. Setecting the Correct Need!e To ensure a reliable stitch formation, make sure the correct needle is inserted in the machine. Needle Systems The Pfaff 145 unison-feed machine in Models H 1 and H 2 uses System 134 needles, while Model H 3 uses System 134-35, and Model H 4 System 190 needles.
Select the proper needle and thread sizes from the chart below: Model Needle Size Cotton Silk Synthetic Linen 60 130/3 140/3 200/3—150/3 130/4 A 70 100/3 120/3 140/3—120/3 H1,H2 100/4 80 80/3 100/.
7. Changing the Needle Raise the needle bar to its highest point, loosen needle set screw A (Fig. 8) half a turn, and pull the damaged needle out of the needle clamp. Insert a new needle into the clamp, making sure that its short groove faces toward the sewing hook.
9. Drawing Up the Bobbin Thread Hold the end of the needle thread and turn the balance wheel toward you, as indicated by an arrow in Fig. 1, until the needle moves down and up again. As the needle moves up, it catches the bobbin thread which comes up with it through the needle hole.
Adjusting the Lower Tension The tension is correct if a noticeable resistance of spring V (Fig. 7) has to be overcome when pulling the thread out of the bobbin case. Take the bobbin case out of the machine and regulate the tension by turning screw Z, (Fig.
12. Regulating the Pressure on the Materia’ The amount of pressure to be exerted by the presser foot must be adapted to the material to be sewn. The pressure is set correctly if the material is advanced through the machine evenly without being injured by the teeth of the feed dog.
14. The Safety Clutch Model C and D machinee are equipped with a safety clutch which prevents disturbance of the hook timing and damage to the bobbin case base in case of thread jamming in the hook raceway.
16. Setting the Foot Lift To adapt the foot lift to the thickness of the material to be sewn, loosen wing nut F (Fig. 15) and adjust the position of lifting eccentric connection H in the slot of the lifting crank. Move the connection upward for a higher foot lift, or downward for a lower foot lift.
17. Operating the Treadle of the Pfaft 145 Equipped with -900 Thread Puller/Trimmer On special request, the Pfaff 145 in Models A and B can be equipped with the time- and cost-saving subcl. -900/06 thread puller/trimmer. On subcl. -900/02 machines, thread trimming, needle positioning and reverse sewing are all controlled by operating two treadles.
18. Trouble Shooting Machine Skips Stitches Cause Remedy Wrong needle system. For correct needle system see Chapter 6. Needle bent. Insert new needle as instructed in Chapter 7. Needle inserted incorrectly. Orient needle so that its short groove faces toward the sewing hook.
