How To Oil Singer Sewing Machine 6233

Getting Started

Before performing any kind of maintenance on your Singer 6233 sewing machine, it’s important to make sure you are wearing appropriate safety protection. You should wear protective gloves and eye protection, as well as ensuring you have read and understood the machine manual before getting started.
Oil is essential for any sewing machine’s performance, and the Singer 6233 is no exception. It should be oiled frequently – approximately every three months – however this may vary depending on how often you use your machine.

Identifying Oil Points

Singer 6233 machines have lint filters which need to be cleaned on a regular basis, and these can be found underneath the base of the machine. You should use a small brush and a damp cloth to wipe away any lint or dirt from the point of the filter. The lint filter can also be unscrewed and removed for more thorough cleaning.
The needle bar also needs to be oiled occasionally – to identify the oil points, simply remove the bobbin case and check for any signs of oil leakage or wear. If required, the entire needle bar can be removed and cleaned with a damp cloth. It’s important to ensure that any residual oil or lint is wiped away before re-assembling the needle bar.

Oil Dispenser

The oil dispenser on the Singer 6233 sewing machine is located on the right side of the machine and can be easily accessed by unscrewing the oil cap. Using a suitable oil, you should then fill the dispenser until the oil level is just below the top of the dispenser. Oil should then be applied to the machine components where needed – the lint filter, needle bar and shuttle all need to be oiled.
The machine needs to be on for this last step – use a clean cloth to apply the oil to all the machine’s moving parts, ensuring that all metal surfaces are lightly oiled. The sewing machine’s components should be checked frequently for wear and tear – if any of the machine’s parts are worn or damaged, they should be replaced promptly.

Clearing Jammed Threads

Occasionally, a Singer 6233 may experience jamming threads. If this happens, the machine needs to be unplugged and the bobbin case, shuttle and needle bar should be carefully removed. Jammed threads should then be cleared away, and the shuttle and bobbin should be inspected for any dirt or residue that could be causing the jam.
It’s important to ensure that all the threads are carefully un-jammeed, and no force is used. If any threads are left, the machine should be fully reassembled and the jam tested – if the jam persists, the bobbin case and shuttle should be removed and inspected again for any signs of damage or wear.


If your Singer 6233 isn’t working as expected, take a look at the machine manual for troubleshooting tips. Common problems may include the machine not stitching, needles breaking, or the bobbin malfunctioning. It’s important to ensure that the machine is threaded correctly before attempting any troubleshooting – often this is the cause of any problems.
If the problem persists, you should take your machine to a qualified repair technician – they should be able to diagnose and fix any issues quickly and efficiently.

Maintaining Your Singer 6233

The Singer 6233 sewing machine is a robust and reliable product – if it’s properly maintained, it can last for many years with few problems. As mentioned above, occasional oiling is essential for the machine’s performance and longevity – oil should be applied to all moving parts and lint should be cleaned out from the lint filter regularly.
To get the most from your machine, it’s also important to use good quality thread and needles. If a needle breaks, it should be immediately replaced with a new one – leaving a broken needle inside the machine can damage the bobbin, shuttle and other parts.
Finally, always check the thread is threaded correctly before using the machine – incorrect threading can cause damage and can be a cause of many types of problems.


Cleaning your Singer 6233 regularly is essential to ensure optimal performance – lint filters should be cleaned every few months and oil should be applied to all the machine’s moving parts. The needle bar, shuttle and lint filter should also be inspected regularly for any signs of wear or damage.
To remove any dirt or lint, you should use a vacuum if possible – this is an effective way to get into all the hard to reach areas of the machine. You should also use a soft, lint-free cloth to wipe away any oil or dust from the machine’s exterior.


When the Singer 6233 isn’t in use, it’s important to keep it stored safely. The machine should be stored in a dry and temperature-controlled environment, away from direct sunlight. You should also use a sturdy cover to protect the machine from scratches and dust – machine covers are available from any good sewing supplies store.
When not in use, the machine should be regularly maintained – the oil dispenser should be checked and re-filled with oil, and the needle bar, shuttle and lint filter should be carefully inspected for any signs of wear or damage.

Aftercare Service

It’s recommended that you get your Singer 6233 checked at least once a year to ensure it’s in good working order. A qualified technician should be able to inspect and diagnose any potential problems, and your machine will be protected by warranty.
Before taking your machine in for the annual check-up, it’s important to make sure it’s fully oiled and all lint has been removed from the machine. This will help to ensure that the machine is functioning optimally, and any potential repairs or replacements can be done in a timely manner.

Understanding Needles

When choosing needles for the Singer 6233, you should consider several different factors. Firstly, you should determine whether the needle is suitable for your project – the size and type of needle you use will depend on the type of fabric you are working with.
Secondly, you should pay attention to the needle type – ball point needles are designed for knitted fabrics, and universal needles are designed for woven fabrics. Finally, you should also check the needle manufacturer – good quality needles are usually made from stronger material, which will help to ensure maximum durability.


Caring for your Singer 6233 sewing machine is essential for optimal performance – the machine should be oiled, cleaned and stored appropriately, and all components should be checked regularly for wear and tear. Additionally, good quality thread and needles should be used in order to get the most from your machine.
If you take good care of your Singer 6233, it can last many years with few problems. Yearly check-ups will also help to protect your machine and will give you peace of mind that your machine is in good working order.
