Safety in changing old light bulbs...
Recently I received an old Singer in for service and was requested
to remove the old light bulb, well part of it, the base. The customer
had tried to remove the bulb, however because of the small area,
tight fit and length of time, it was not easy to remove and he (the
husband) broke the glass portion and cut his fingers. Not good!
To help avoid this problem here are some recommendations...
Unplug the machine from the wall electric out-let.
For better access remove or loosen the light assembly if possible.
Purchase a rubber chair cushion foot with the inside diameter approximately the same as the outside diameter of the glass portion of the bulb. Or order Viking bulb extractor #412 3275 01 for most bulbs and #412 5701 01 for new smaller bulbs.
Place the bulb extractor over the glass portion to protect from cutting your fingers should the glass brake. This will also give you a firmer grip.

Remember most
Singer's use the
push-in-and-turn
type of bulb referred
to as Bayonet.
The old bulb, in most cases, has been in the machine for many years, this has caused it to become somewhat frozen in place and at the same time become brittle where the glass is fused to the base. Remember be safe.
If you are not comfortable performing this or any adjustment take your machine and control to your local dealer.
