OILING:---It is necessary to oil the machine once a weak . If you use it

infrequently , then once a month should be sufficient . To oil throughly ,

remove the upper , needle plate , slide plate ,face plate , bobbin case ,

needle and presser foot . Read the instruction manual for location of

parts needing application of oil .One drop of oil is enough for each

point . while oiling turn the fly wheel back and front to help the oil

flow to the moving parts . After oiling the points on the head of the

machine till the machine head back to oil the points on the under

side . Before you close the machine run it slowly for several minutes

on on a weast piece of material and keep the material under the

presser foot. The fabric will absorbs the excess oil .

CARE OF THE MACHINE

CARE OF THE MACHINE

Regular cleaning , Oiling and care of the machine ensure satisfactory

sewing and a long life for the machine . When not in use , keep your

machine covered to prevent dust from settling on it .

CLEANING :---You should always remove lint deposits , dust and threads

bits before oiling any part of the machine . Use a small dry brush or

old cloth to remove dust and lint . To clean the feel dog , remove the

needle plate of the machine and brush off durt .To clean the shuttle

race , remove the two screws holding the shuttle race assemble to the

machine , take out the shuttle race and wipe its groove free of dirt

,fluff and broken bits of thread .

ADJUSTING THE STITCH LENGTH :---To adjust the stitch length , loosen the stitch regulator knob ,

move it to the desired number on the marked plate and

tighten the knob . On local method models of machines ,

the higher numbers denote longer stitches. It recent models of

machines the the stitch regulator also has a setting for reverse

stitching .

ADJUSTING THE PRESSURE OF THE PRESSURE FOOT :--Ordinarily this adjustment need not be done for sewing on fabrics of

medium texture . In general , coarse fabrics require a heavier presser

while sheer fabrics require light pressure only . The presser foot bar

screw is turned to the right to increase pressure and to the left to

decrease pressure .

ADJUSTMENTS

Testing and adjusting tension :---When there is perfect balance of

tension between the upper and lower threads , the stitches lock

or meet together in the middle of the thickness of the cloth .

when the upper tension is too tight , the spool thread lies

straight on the top of the fabric and the upper thread

appears like loops on the upper side of the cloth . If the

upper tension is to loose , the upper thread lies straight

on the upper side of the fabric and the upper thread

appears like loops on the underside .An easy method of recognising tension is to stitch diagonally

across a square of fabric folded on , and then to stretch the cloth firmly between your fingers

until one or both threads break . The thread which is broken is always the one with tighter

tension . If the tensions are balanced break together and require more force to break . To



increase or decrease upper tension , turn the screw on the tension regulator with the presser

foot down .In turning this screw remember that right is tight and left is loose . Usually there will be


numbers written on the tension dial . To increase tension you should turn towards the higher

numbers and to decrease , towards the lower numbers .

Avoid changing the lower tension unless you are sure that the

tension cannot be corrected completely by adjusting the top one alone .

The lower tension is adjusted by turning the small screw on the

bobbin case using a screw driver . usually the screw is turned to the

right to tighten and to the left to loosen . Make a very slight turn only

each time .

FASTENING THE THREAD ENDS :---It is necessary to fasten the threads at the ends of

stitching lines which are not to be later this can be

done in two ways .

1. Stitch back a short distance along the seam before cutting the

thread . This is called privoting .

2.After to have reached the end of stitching line pull the back and cut

the threads lining a length of about 5" to 6" .Pick up the last stitch

with a pin and so as bring out both thread ends to the wrong side

of the fabric . Now tie a double knot .

SEWING ON FABRIC :---Pull the upper and under threads straight back under the presser foot

place the cloth to be stitched under presser foot with the seam

allowances to the right of the needle .On the rest on the material to

the left .Now turn machine slowly guidings the material gently with

both your hands and then gradually increase the speed of the

stitching.

DRAWING THE BOBBIN THREAD :---Raise the take-up lever takes highest point

holding the end of the top thread turn the fly wheel around so that the needle

goes down , comes up to a highest position . Then pull the top thread to bring

the bobbin thread loop out .
