Steps to Open a Pfaff Sewing Machine
Pfaff sewing machines have been providing sewers with reliable stitching and beautiful designs for almost 200 years, and are even favored choices among professional seamstresses today. Unfortunately, due to their age and prior use, some machines may be difficult to open, or may even require special safety measures and tools. Neither of these should be daunting obstacles – with a few simple steps, any person can learn how to open the Pfaff sewing machine.
The task of opening a Pfaff sewing machine is actually not difficult. Before starting, however, it is important to find out if the model or serial number of the machine is known by the user and if known, check the manual for safety regulations and general information. Additionally, any special techniques for that particular model should be familiarized.
The most challenging part of opening the Pfaff sewing machine is making sure all safety precautions are followed. As all Pfaff sewing machines, regardless of age, have mechanisms that may easily be damaged, utmost care should be taken while opening the machine. A small screwdriver is usually all that is needed, as well as any specialized tools if needed. It is advised not to use any metal-tipped tools as they could easily damage the metal interior.
Once safety precautions have been taken care of, the next step is to unscrew any exterior panels. The most common screw size for Pfaff sewing machines is 3/16 inch. A small screwdriver should be used when unscrewing the exterior. After the screws are removed and all exterior panels are taken away, a second bolt will be exposed. This is the motor housing; both aluminum and plastic covers need to be removed from the motor.
A few additional pieces may hide underneath the motor housing, and these should be removed as well. Once all pieces are safely taken off the machine, and any other screws have been carefully loosened, the machine should be opened and the interiors will be visible. It is important to handle all pieces with care, as they may be fragile and easily damaged.
Should the user wish access to the interior workings of the Pfaff sewing machine, the main structure can be opened by taking out some screws. This is usually done in order to aid in cleaning and maintenance. To open the main frame, all screws must be taken out save for one; this one screw must be used as the main point for propping the frame open to access the interior parts.
If the user wishes to access the motor, or replace major components or attachments, the motor of the Pfaff sewing machine can also be opened. To do this, the motor cover must be lifted up, and some screws may need to be removed from the inside if the motor does not just simply lift away. Wires and other pieces should be handled carefully and the user should check for any obstruction.
Removing the Bobbin Case
The bobbin case lies at the bottom of the needle plate and aids in the guidance of the thread during the sewing process. While removal of the bobbin case varies per machine and model, it usually follows the same set of steps. The first step is to remove the needle plate by loosening the four screws at the base of the sewing machine. Afterward, the bobbin will become visible and can be taken out. The bobbin cover or wire need to be removed as well.
Some Pfaff sewing machines may require the thread to be taken off in order to properly remove the bobbin case. Afterward, the bobbin holder must be lifted out of the machine and can be easily taken out of the slot. For machines with a combination bobbin holder and feed dog, an extra spring must be removed. Once the bobbin holder is taken out, the bobbin case can be removed and the machine can now be reassembled.
Cleaning the Pfaff Sewing Machine
The Pfaff sewing machine should be cleaned Monthly or at least every three months. Cleaning should be done from the inside out and be a gentle process as Pfaff sewing machines are delicate and may be aged or used. The bobbin area should be cleaned using a small brush, preferably of the non-metallic variety. This helps to take out any lint or dust that may be found in the bobbin.
The needle plate should be cleaned by using a soft damp cloth and a dedicated needle plate cleaner. Steel wool should not be used and all the dirt must be removed. For the outer surface, only a dry cloth should be used and no special cleaner except for glass cleaner may be applied. The feet, stitch plates, and other accessories should not be forgotten in the cleaning process.
Oil and Grease Maintenance
Depending on the model and condition of the machine, oil and grease maintenance should be performed once a year. This helps keep the machine lubricated and running smoothly. Special lubrication should be used, according to the manual, as regular oils and grease may cause damage. Special oiling tubes, available in most stores, can be used instead virtual all models.
It is important to only use special Pfaff lubrication and avoid using grease, as it is much more difficult to take out. If the machine does require grease, many of the manual’s direct from Pfaff can provide the type or brand that should be used.
For specific areas, individualized attention is needed. Any plastic outdoor part should be greased with a white lithium grease. All gears and other metal parts should be oiled instead of greased, and again, the lubrication needed is listed in the manual.
Replacing Function Parts
At times, Pfaff sewing machines may require supplementing of parts, for example an electric motor, pulley, regulating lever, feed dog or one of the many other parts. If this is the case, it is essential to replace the part with the size and model specified in the manual. A substandard replacement may never sync with the mechanical workings and may even cause an injury to the user.
For electrical components, extra care must be taken when replacing them. This is because electric components may be easily damaged and may also present a safety hazard if replaced incorrectly. The user should coordinate with a professional mechanic or electrician if needed, as electricity can be lethal if handled carelessly.
Testing the Pfaff Sewing Machine
After the machine has been opened, cleaned and repaired, it is important to test it before use. All wires and connectors must first be checked before threading and tension checking can begin. For threading, refer to the threading instructions as mentioned in the manual. Tension should also be adjusted accordingly.
To test the machine while threading, it is recommended to test press several inches of fabric with it. This should be done in order to make sure the machine is running well and that the tension is properly adjusted. If the difference between top and bottom threads is too big, then the tension should be adjusted following the tension instructions provided by the manual.
Once the above tests are carried out and all necessary adjustments are made, when at a point to use the machine, the user should make sure it is set up in a place with enough light and make sure all supplies are within reach. If the machine is being used in a different environment, it is also a good idea to check if the size of the machine is adequate for its surface.
Storing the Pfaff Sewing Machine
Pfaff sewing machine should be stored in a warm, clean, and dry place. Rusty or dusty Pfaff sewing machines can pose a safety hazard, so keeping the machine clean is highly recommended. If storing for a longer period of time, such as in cases of seasonal use, all protections should be taken in order to avoid any untoward future repair or maintenance. It is highly advised to keep the original manual, as it recommends the best measures.
Using the Pfaff Sewing Machine
When the machine is set up, ready to use, a few tests should be done. Firstly, the user should check if all loose parts are secured, no debris is present in the bobbin case or in the feather plate, and if the needle is properly set up inside the machine. To start the machine, all safety features should also be checked, including whether a cover or protective lid is in place, and if the machine is properly grounded.
The Pfaff sewing machine should be started at a low speed, and the user should never leave it unattended. Overextending the machine, too much tension or the wrong type of needle can all damage the machine. To make sure the machine is working at its best, the user should regularly check the bobbin case, needle and other mechanisms to make sure they are still in good condition. The manual can also provide additional information on certain functionalities, such as the reverse button, delayed starting, and others.
