The astonishing creative machine not only gives users a practical tool, it empowers the user for creative expression. When users appropriately care for their sewing machines, they perform marvelously year after year.
When sewing machines are neglected, exposed to environmental pressures, or neglected over time; they gradually fail to work. The oils and grease used to lubricate the sewing machine becomes infused with lint, dust, dirt, and debris. It loses viscosity. It dries and becomes gummy. Eventually, they crystallize and become encrusted inside the sewing machine. The result is a sewing machine that eventually fails to operate. The shafts become bound up with the debris, lock up solid, and freeze into an immovable hunk.
When you find a frozen sewing machine, it is no easy fix. It requires highly a skilled sewing machine technician to fix a locked up stuck sewing machine. You can easily tell when a sewing machine is bound up by attempting to turn the hand wheel. If it binds, resists turning, or freezes solid; it is dead head stuck.
Repairing a sewing machine that is locked up can be very frustrating. At first it seems the whole machine has melted into a single slab of steel and plastic.
After you become explosively frustrated working on a dead head machine for several hours, stop. Take a break. Follow some simple steps described below to unfreeze the machine.
So, what really causes bound up machines?
Lack of care, Problems in the bobbin and hook assembly, and broken parts are the causes of bound up.
Repairing bound up sewing machines, depends on the removal and elimination of crude in the machine. All the debris, lint, and crystallized lubricants must be removed. When the wrong lubricants are used, they gum of the machine. When lubricants are permitted to dry out, get gummy, and harden into crystals, they lock up the sewing machine. As long as they exist, they cause problems.
Lint, debris, and old gummy lubricants can cause binding in the bobbin and hook area. Failure to clean out the bobbin area every few hours of sewing can cause a sewing machine to be bound up.
Sewing machines can also lock up when a part inside the sewing machine breaks. If a gear breaks a cog, it can lock up. If a lever bends, it can lock up. If a cam assembly breaks, the sewing machine can lock up.
Exactly, how do you fix locked up sewing machines?
If the hand wheel on the sewing machine is difficult to turn, the first thing to do is clear out the bobbin area. Open bobbin area. Remove bobbin and bobbin carrier. Clean it out. Try the hand wheel again.
Take off all the covers: top cover, bottom cover, and side covers. Blow out the machine using an air compressor. Look for threads wrapped around any parts and eliminate. Brush away and remove any encrusted debris. Lubricate the sewing machine appropriately. Test hand wheel again.
Release the power drive mechanism or belt from the hand wheel. Again test the hand wheel. Sometimes, tensioners and various pulley assemblies can freeze, so make sure that all of these are turning freely.
Remove all debris, old oils, and grease. Thoroughly clean the upper and lower sewing machine. Use carborator cleaner or similar chemical to dissolve an old sticky and gummy lubricants. Use chemical cleaners as necessary. Test the hand wheel again. Beginning at the hand wheel follow the drive mechanisms across the upper and lower parts of the sewing machine. Force the hand wheel to turn even a slight amount. Look for binding points. Find the points of resistance.
If you find a bind between metal parts that just wont give, add lubricant. Move the pieces back and forth to loosen and free them. Work the binding areas until they become free. In extreme situations, you may use a torch or soldering iron to heat up a binding point. The heat will dissolve the old lubricants and enable you to free the bind. An extreme measure use to be used with really old machines without electronics and plastic parts, is to soak the machine head in strong solvent for several hours. - 16890
