Users learn to engage the winding lever and monitor the bobbin as it fills, ensuring even distribution. The manual then illustrates proper bobbin insertion, varying slightly depending on the specific 158 model.
Some utilize a drop-in bobbin system, while others employ a front-loading bobbin case. Correct insertion is vital for consistent tension and preventing skipped stitches, as highlighted in the manual’s diagrams.

Threading the Kenmore 158
The Kenmore 158 manual details upper and lower threading guides, emphasizing correct pathing for both threads to ensure proper stitch formation and tension.
Upper Threading Guide
Successfully threading the upper portion of your Kenmore 158 is crucial for consistent stitching. The Kenmore manual illustrates a specific path, beginning with the spool pin and guiding the thread through the first thread guide.
Next, the thread proceeds through the tension discs – ensuring proper tension is vital for balanced stitches. Following this, the manual directs you to thread the take-up lever, a moving component that controls thread delivery.
Carefully guide the thread through the remaining thread guides before finally leading it down through the needle clamp and threading the eye of the needle. Referencing the manual’s diagrams is highly recommended, as incorrect threading can lead to skipped stitches or machine malfunctions.
Lower Thread (Bobbin) Threading
Proper bobbin threading is essential for the Kenmore 158’s operation, and variations exist between models. Some 158 series machines, like the 158.19400, feature a bobbin system without a bobbin case, simplifying the process.
Generally, the manual instructs winding the bobbin evenly and inserting it into the bobbin holder, ensuring it rotates freely. The thread is then drawn up through the slot or tension spring, depending on the specific model.
Carefully follow the manual’s diagram for your 158 variant, as incorrect bobbin insertion or threading can cause tangled threads and stitching issues. Consulting the manual is vital, especially when comparing different 158 series bobbin systems.
Tension Adjustment
Correct tension is crucial for balanced stitches on the Kenmore 158. The manual details how to adjust both upper and lower thread tension. Begin by testing on scrap fabric, observing the stitch formation.
If the upper thread is looping on the underside, increase the upper tension. Conversely, if the bobbin thread is visible on the top, decrease the upper tension. Minor adjustments are key; small dials control these settings.
Refer to the manual’s illustrations for the precise location of the tension dials on your specific 158 model. Proper tension ensures even stitch quality and prevents puckering or thread breakage, vital for successful sewing.

Basic Operation and Maintenance
The Kenmore 158 manual guides initial setup, troubleshooting, and routine cleaning. Proper maintenance—lubrication and addressing common issues—ensures longevity and optimal performance.
Getting Started: Initial Setup
Before your first project with the Kenmore 158, the manual emphasizes preparing the machine correctly. This involves carefully reviewing the threading diagrams for both the upper and lower threads – a crucial step for proper stitch formation.
Specifically, the manual details how to wind the bobbin evenly, ensuring consistent tension throughout your sewing. It also instructs on correctly inserting the bobbin into its case, a process that varies slightly depending on the specific 158 series model.

Lubrication is crucial for smooth operation. The manual details specific lubrication points, advising the use of sewing machine oil. Avoid over-oiling, as this can attract dust and create further issues.
Regularly cleaning the bobbin area and feed dogs is also recommended. Following these guidelines, as outlined in the manual, will prolong the life of your Kenmore 158 and ensure consistent, reliable sewing.

Advanced Techniques & Troubleshooting
The Kenmore 158 manual assists with thread breakage, fabric feeding issues, and bobbin case problems, offering solutions for experienced users and repairs.
Dealing with Thread Breakage
Frequent thread breakage on your Kenmore 158 often indicates a setup issue, as detailed in the service manual. First, re-thread the entire machine, ensuring the presser foot is up during threading – a crucial step often overlooked.
Next, verify correct tension settings; too-tight tension strains the thread. Consult the manual’s diagrams for proper adjustments. Also, inspect the needle for damage (burrs or bending) and replace it if necessary. Using the wrong needle type for your fabric can also cause breaks.
Finally, ensure the bobbin is correctly inserted and wound evenly. A poorly wound bobbin creates inconsistent tension. The Kenmore 158 manual provides clear illustrations for these procedures, helping you diagnose and resolve these common issues efficiently.
Addressing Fabric Feeding Problems
Fabric feeding issues with your Kenmore 158 often stem from a few key areas, detailed within the service manual. Initially, check the presser foot pressure; insufficient pressure won’t grip the fabric effectively. Adjust according to the manual’s guidelines.
Subsequently, examine the feed dogs – ensure they are clean and moving freely. Lint buildup can impede their function. The manual illustrates how to access and clean them. Furthermore, verify the stitch length setting isn’t set to zero, as this prevents fabric movement.
Lastly, confirm the bobbin case isn’t overfilled, which can cause tension imbalances affecting feed. Refer to the Kenmore 158 manual for proper bobbin loading techniques to restore smooth fabric feeding.
Bobbin Case Issues and Solutions
Bobbin case problems on the Kenmore 158 frequently involve incorrect insertion or tension adjustments, detailed in the service manual. First, ensure the bobbin is wound evenly and inserted correctly, following the diagram in the manual. Improper insertion can cause skipped stitches or jamming.
Next, check the bobbin case tension. The manual provides instructions for adjusting the screw; too tight or loose tension leads to poor stitch quality. Additionally, inspect the bobbin case for any damage or debris. A bent or dirty case hinders smooth operation.
Finally, different Kenmore 158 series (like 158.17851 vs. 158.19400) may have varying bobbin systems – consult your specific manual for accurate guidance.
