88.6 The Singer Heavy Duty 4452 is the pinnacle of the Singer Heavy Duty line of sewing machines.  This mechanical sewing machine sews very quickly and is very easy to setup and to use.  It is a good fit for both the beginner and the more advanced sewist.  It is also easy to thread and is capable of sewing through thick materials such as denim, leather and canvas.  On the downside the foot pedal feels poorly made and it does not regulate speed well.  In addition, a number of folks report struggling with tension issues.

What Are Owners Saying?
Most owners are both surprised and pleased with the exceptional sewing speed of the 4452.  It has a maximum sewing speed of 1100 stitches per minute which is faster than many machines (we typically see around 800 stitches/minute or so).
Another very popular point is just how easy the machine is to operate.  It is a mechanical sewing machine and it is quite basic.  Most owners feel that the controls make it easy to work with and easy to set up.  In addition, there are quite a few comments stating that this is a good machine for a beginner or even a more advanced user.
Singer 4452 Controls
For the most part, folks report that the 4452 is very capable of sewing through thick materials such as denim, leather and canvas.  There are a few comments that the machine is not as capable as expected but these are few in number.  To this end, it is important to highlight that this machine is stated to be “heavy duty” – it is not industrial grade.
Other positive comments include that the 4452 runs smoothly, that it feels sturdy, and that it is something of a workhorse.  It is also very easy to thread using the automatic needle threader.
Singer Heavy Duty Bed Plate
However there are some issues.  One of the most common is frustration dealing with Singer customer service.  This is not a problem if the machine works well, but if something breaks or ceases to work such that the machine requires repairs then you will have to deal with Singer.  We’ve seen complaints about the company’s customer service for years now and it does not seem to get any better.
Also, the foot pedal that is provided with the 4452 seems cheaply made.  Some folks call it plasticky and say that it is not very good at regulating the sewing speed.
Finally, there are a number of comments highlighting issues related to setting and maintaining thread tension.

Singer Instructional Videos
Singer has created a host of instructional videos for the 4452 and these are available on YouTube.  They cover areas such as stitches, buttonholes, needle threader, top drop-in bobbin, presser foot, needle positions, drop feed, etc.  An example is provided below.

The Singer website states that the Heavy Duty 4452 carries a limited 90 day / 2yr / 24yr warranty (despite many other sites stating this unit comes with a 25 year warranty).  To the best of our knowledge this breaks down as follows:
90 days - covers belts, bulbs, rings, attachments, and adjustments
2 years - covers electronic components, motors, light assembly, speed control, switches, and wiring
24 years – covers the sewing machine head 
It is interesting to note the 24 year warranty on the sewing machine head.  We have always seen 25 years in the past.   We are not sure if this is something new from Singer or if the 24 years is something only applied to certain machines.
The 4452 weighs in at 14.6 lbs which is actually a little lighter than expected for this “heavy duty” machine.  It is not so light that it would be ideal for taking to classes but it is certainly not as heavy as many other machines on the market.
Sewing Machine Manual
The manual provides instructions in 3 languages - English, French and Spanish.  It covers the principle parts of the sewing machine and the accessories.  It also provides information on threading the machine, all the sewing features, the sewing feet, maintenance, and troubleshooting.  You can view a copy of the manual here: Singer Heavy Duty 4452 Manual
