(Servo ) Direct Drive machine bedplate press to pack sketch map CAUTION The sewing machine should only be installed by a qualified technician. Ask your Brother dealer or a qualified electrician for any electrical work that may need to be done. The sewing machine weighs more than 49 kg.The installation should be carried out by two or more people.
Installing the machine head Install pulley cover base on machine bed with two hexagonal bolts and two washers . Insert two bar cushione into the bottom of the bed. At this time,install the two hexagonal bolts so that they go as far as possible into the notches in the pulley cover base .
After fastening cushions to the machine bed and pulley cover base with set screws ,fix them to the table with screws . Place the work table so that the machine h- ead is horizontal. If the machina head is not horizontal,lubri- cation will not be carried out correctly.
Place pulley cover A so that it is in bet- ween the eight pulley cover seats ,and t- hen secure it to the pulley cover base with the four screws . Push the belt downward,and then install pulley cover B to pulley cover A with the three screws .
Cotton stand Assemble the cotton stand while referring to the cotton stand instruction manual. Install the cotton stand to the cotton stand mounting hole in the work table with nut . Lubrication CAUTION Be sure to wear protective goggles and gloves when handing the lubricating oil gets into your eyes or onto your skin,otherwise inflammation can result.
Use only the lubricating oil Insert the rubber plug and then close the front cover . Add 1-2 drops of oil once a weed to needle bar bracket lubrication hole . Periodically loose the oil drain screw drain out any oil which collects the front bed oil sump.After draining the oil,tighten the oil drain screw Periodically wipe away any oil which col-...
Insert the power cord plug into the wall outlet,and then turn on the power switch. I f the direction of rotation is reversed,chan- ge the direction of rotation to the correct di- rection while referring to the instruction m- anual for the motor. For the first 3-4 days of use,do not run the machine at 500 spm lower than the usual speed.This will help contribute to a longer...
Threading the lower threads CAUTION Pass the lower threads as shown in the figure below. 3 2 1 Threading the upper threads CAUTION Pass the lower threads as shown in the figure below.
Sewing CAUTION Switch the power on step down on pres- ser for lifter pedal ,place a fabric under presser foot,and release presser foot lifter pedal to start the machine . Depress treadle After sewing the work,keep sewing until it reaches thread cutter ,and then cut the threads with thread cutter .
Thread Tension Adjusting the thread tension Upper thread Good stitches Lower thread Loose , bad stitches Thread tension differs with sewing conditions.Adjust it to suit your particular sewing conditions Less tension More tension Adjust the upper thread tension properly by turning upper thread adjusting screw Adjust the lower thread tension properly by turning lower thread adjusting screw...
Stitch Length Adjustment CAUTION The numerals on the machine pulley scale represent the stitch length(mm) however the actual stitch length will vary depending on the type and thickness of material being used . Open the front cover While pressing the feed adjustment button ,turn the machine pulley toward you slo- wly,(The feed adjustment button will m-...

Cleaning The following cleaning operations should be carried out each day in order to intain the performance of this machine and to ensure a long service life. CAUTION Daily cheaning Open the looper side plate and clean away any thread scraps and other rubbish . After cleaning,close the looper side plate .
Fill the machine with oil until the oil level reaches the point in between the reference lines on the oil gauge . Close the forward feed arm cover and s- ecure it with the 11 screws . Machines with puller Remove the eight screws ,and then open the puller top cover...
Needle bar height adjustment Adjust the heights of the needles At this time,adjust so that each needle is in the center of the needle hole in the needle plate . Remove the screw ,and then remove the presser foot . Turn the machine pulley to drop the needle bar to its lowest position.
Needle and looper timing adjustment Make an adjustment so that,when needles are down lowest loopers reach the end of their backward travel and the distance from the ne- edle center to the looper tip is 2.7 to 2.9 mm . Remove the presser foot,needle plate and feed dogs.
Timing of loopers running clear of needles The loopers run in back of the needle in their forward travel and in front of the needle in th- eir backward travel.Adjust the clearance bet- ween the needles and the loopers to anywhere from 0.05 to 0.10 mm in the forward travel.
Needle guard adjustment The clearance between the needle guard and the needles should be 0.2mm when the stit- ch length is at the minimum setting and the l- oopers are moving toward the needles. The heights should be adjusted to as low a se- tting as possoble without the loopers breaking.
Feed dog height adjustment Make an adjustment so that the highest part of the feed dog will be 1.2 mm above the needle plate when feed dog is at the highest position. Adjust the height of feed dog by turning feed Becomes bar eccentric shaft .
Upper thread take-up thread guide adjustment Adjust the distance between the center of the upper thread take-up and top of the thread gu- ide will be 6-7mm. Turn the pulley toward yourself until the n- eedle bar is down at the lowest position. Loosen the screw ,and then move the up- per thread take-up thread guide up or do- wn to adjust so that the distance from the...
Thread release shaft adjustment Adjust the thread release shaft so that thread tension discs loosen when the presser foot is raised and tighten when the presser foot is l- owered. Loosen set screw . Make an adjustment by turning thread rel- ease shaft so that the thread tension discs begin to loosen when the presser foot rises 4mm above the top of the needle plate.
Adjust felling distance of point A by loosing set screw . After the adjustment,retighten set screw . Adjust felling distance of point B by loosing set screw . After the adjustment,retighten set screw . Puller height adjustment (Machines with puller) Adjust the height of puller so that it is 0.1 to 0.2 mm high from the top of the needle plate.
