What are the important safety precautions I should follow with the Singer Model 1120?

Always read all instructions before using the machine. Keep fingers away from all moving parts, especially the needle. Use the proper needle plate to avoid needle breakage, and do not pull or push fabric while stitching. Always turn the power switch to 'O' (off) when making adjustments in the needle area, and unplug the machine when removing covers or lubricating.
