5 The sewing speed preset at the time of shipping is 4,000sti/min. The thread trimming speed can be changed within the range of ( ). The thread trimming speed preset at the time of shipping is 420 sti/min.*1 : When stitch length exceeds 4 mm or more, set the max. sewing speed to 4,000 sti/min or less for use. *2 : Needle used depends on the destination.*3 : MA type is for light-weight materials. In the case the sewing machine is used with its speed of stitch set at 4,000 sti/min or higher, the presser regulating spring and thread tension spring should be changed with S type ones. 2 1. INSTALLATION1) Carry the sewing machine with two persons as shown in the figure above.(Caution) Do not hold the mm AB C 2) Do not put protruding articles such as the screw-driver and the like at the location where the sewing machine is ) The under cover should rest on the four corners of the machine table groove.

6 Mount rubber hinge seat on the table and fix it on the table with a ) Fix two rubber seats on side A (operator s side) using nails as illustrated above. Fix two cushion seats on side B (hinged side) using a rubber-based adhesive. Then place under cover on the fixed ) Remove air vent cap attached to the machine bed.(Caution) 1. If the sewing machine is operated without removing air vent cap , oil leakage from gear box portion C may occur. 2. Be sure to attach cap when transporting the machine head in the state that the ma-chine head is removed from the machine table. 3 6) Fit knee lifter pressing rod . Fit hinge into the opening in the machine bed, and fit the machine head to table rubber hinge before placing the machine head on cushions on the four ) Securely attach head support rod to the table until it goes no further.

7 Regarding the control panel , remove two side plate fixing screws , place the rubber packing , which is one of the accessories of the control panel , between the head section and control panel , then fix them together.(Caution) 1. Do not use the screws supplied as accesso-ries of control panel . 2. Be sure to mount the machine head support rod on the machine table so that its height from the table surface becomes 55 to 60 mm. For the sewing machine provided with the AK device, be sure to mount the support rod on the table so that its height from the table surface becomes 38 to 43 ) Bundle cable clip band supplied as accessories of the machine head at the root of the ) Check to be sure that the table and the safety switch arm are engaged with each other by mm to mm, with the sewing machine slightly tilted.

8 (Caution) If the engagement between the table and the safety switch arm is 2 mm or less, Error 302 may occur at the time of startup. Or, if the aforementioned engagement is mm or more, safety switch arm may ) If the engagement between the table and safety switch arm is outside the range of mm and mm, loosen safety switch mounting screw and tilt safety switch in the direction of the arrow to adjust the engagement of safety switch arm with the table. to mm 4 1) Assemble the thread stand unit, and insert it in the hole in the machine table. 2) Tighten nut .3) For ceiling wiring, pass the power cord through spool rest rod . The standard height of the presser foot lifted using the knee lifter is 10 mm.

9 You can adjust the presser foot lift up to 15 mm using knee lifter adjust screw .(Caution) 1. Do not operate the sewing machine in the state that the presser foot is lifted by 10 mm or more since the needle bar comes in contact with the presser foot . 2. Knee lifter initial position If the adjustment screw is over tightened, the sewing machine will operate in a state where the presser foot is lifted up, causing defective sewing or :Turn OFF the power before starting the work so as to prevent accidents caused by abrupt start of the sewing machine. 2. ADJUSTING THE HEIGHT OF THE KNEE LIFTER 3. INSTALLING THE THREAD STAND 5 Fill the oil tank with oil for hook lubrication before op-erating the sewing ) Remove oil hole cap and fill the oil tank with JUKI NEW DEFRIX OIL (Part No.

10 : MD-FRX1600C0) or JUKI MACHINE OIL #7 (Part No. : MML007600CA) using the oiler supplied with the ) Fill the oil tank with the oil until the top end of oil amount indicating rod comes between the upper engraved marker line A and the lower engraved marker B line of oil amount indicating window . If the oil is filled excessively, it will leak from the air vent hole in the oil tank or proper lubrication will be not performed. In addition, when the oil is vigorously filled, it may overflow from the oil hole. So, be careful. Upper engraved marker line3) When you operate the sewing machine, refill oil if the top end of oil amount indicating rod comes down to the lower engraved marker line of oil amount indicating window.
