Cylinder R (1A) (1B) Cylinder L (2A) (2B) (2A) (2B) Upper knob Lower knob Manual button <Adjusting the speed controller> You can use the valve knobs to adjust the lifting and lowering speeds. The valve knobs should be adjusted so that the left and right sides of the work clamp operate at the same speed. When the upper knob is tightened, the lifting speed becomes slower. When it is loosened, the lifting speed becomes faster. When the lower knob is tightened, the lowering speed becomes slower. When it is loosened, the lowering speed becomes faster. You can operate the work clamp while the power is turned off by pressing the manual button. 12 jintex.in

3. INSTALLATION 3-12. Lubrication CAUTION Do not connect the power cord until lubrication is complete. If the foot switch is depressed by mistake, the sewing machine might start operating and injury could result. Be sure to wear protective goggles and gloves when handling the lubricating oil and grease, so that they do not get into your eyes or onto your skin. If the oil and grease get into your eyes or onto your skin, inflammation can result. Furthermore, do not drink or eat the lubricating oil or grease. They may cause diarrhea or vomiting. Keep the oil out of the reach of children. The sewing machine should always be lubricated and the oil supply replenished before it is used for the first time, and also after long periods of non-use. Use only the lubricating oil specified by Jack 1. Fill the arm-side oil tank with oil. 2. Move the work clamp arm (1) as far as it will go to the right when looking from the front of the sewing machine, and then slide the outer cover L (2) into the inner cover L (3) so that the lubrication hole in the bed is visible. Pour oil into the bed side oil tank through this hole. NOTE: Be sure to fill the machine with oil when the oil level is down to about one-third full in the oil sight glass. If the oil drops below the one-third level, there is the danger that the machine may seize during operation. (4) (5) 3. Pour oil in through the two holes (4) of the shuttle race base assembly so that the felt is lightly moistened. NOTE: If there is no more oil on the felt of the shuttle race base assembly, problems with sewing may result. 4. If using the liquid cooling tank (5), fill it with silicon oil (100 mm²/s). 14 jintex.in

4. PREPARATION BEFORE SEWING 4. PREPARATION BEFORE SEWING 4-1. Installing the needle CAUTION Turn off the power switch before installing the needle. If the foot switch is depressed by mistake, the sewing machine might start operating and injury could result. 1. Loosen the set screw (1). 2. Insert the needle (2) in a straight line as far as it will go, making sure that the long groove on the needle is at the front, and then securely tighten the set screw (1). 4-2. Threading the upper thread Thread the upper thread correctly as shown in the illustration below. When using threading mode for threading, the tension discs (1) will open so that the thread can be threaded more easily. (Refer to following page.) [If using cotton thread or spun thread] (3) 8 9 6 10 11 12 40mm (1) (2) [If using synthetic thread] Turn the machine pulley (2) and raise the thread take-up (3) to its highest position before threading the upper thread. (This will make threading easier and it will prevent the thread from coming out at the sewing start.) When threading the thread through the needle, allow a distance of approximately 40 mm between the needle hole and the end of the thread. If the trailing length of the thread is too long, it may cause the thread to become tangled. 16
4. PREPARATION BEFORE SEWING <Threading mode> Threading mode is safe because the sewing machine will not start even when the foot switch is depressed. 1 Turn on the power switch. 2 Press the home position key Press the threading key, and the key ! The work clamp will drop. 3 Threading the thread. 4 Ending threading mode Press the threading key, and the key change !
