TO START SEWING
Important hints:
1. Raise the take-up lever to its highest position before starting and after stopping
sewing.
2. Hold both threads about 10 cms to the rear of the machine for the first two or three
stitches.
3. Sufficient fabric should be placed under needle before lowering the presser foot.
4. Depress foot/speed control and start to sew.
5. Test the machine stitches on a scrap of fabric you plan to use, adjusting the machine
for the length of the stitch and tension suitable to your fabric.
6. Separate the machine from the power system if you leave it unsupervised.
Attention:
1. When turning the balance wheel manually, always turn it toward you.
2. Guide the cloth gently with your hand.
3. To prevent breaking needles, always raise the needle out of the fabric when you stop
sewing.
SLIDE SPEED CONTROL
The sewing speed is achieved by using the slide Control in conjunction with the Foot
Control. The Slide Speed Control is moved horizontally to determine the ‘zone’ of speed
required, the far right, being very slow (minimum), through to the left, building up to fast
being the maximum. However, the final speed, within the chosen ‘zone’ can be further
determined by the amount of pressure applied to the Foot Control.
