This machine is intended for use on heavy materials like vinyl, leather and heavy layers of upholstery. The stepping feeding motion promises the consistent feeding of multiple layers or heavy duty materials without stitch gathering or layer unevenness.

Maximum sewing speed is 3,000 stitches per minute!

# Warnings

🚫 Do not push or pull material while stitching.  
⚠️ Power off the machine before threading, inserting the bobbin, or handling the needle.  
⚠️ This machine retains some power in the motor after powering off. Drain it by pressing the foot pedal while keeping hands away from the machine.  
⚠️ Keep hair, loose clothing, and fingers away from all moving parts!

See the Common Hazards section for more information.

## Tool Safety

### COMMON HAZARDS

The most common hazards are thread jams and broken needles. Watch for binds and jams —stop immediately if they occur.

<div class="section_highlight_wrapper" id="bkmrk-this-machine-has-a-s"><div class="level3">- <div class="li">This machine has a safety mechanism to avoid jamming. It must be reset after a jam before continuing. (See Safety Reset)</div>
- <div class="li">Ensure the needle and thread are removed before winding a bobbin</div>
- <div class="li">Avoid pulling/pushing fabric, which may misalign and break the needle</div>

</div></div>The most **significant hazard** is injury. Always power off and run the machine until the motor drains before handling, adjusting, or threading.

<div class="section_highlight_wrapper" id="bkmrk-keep-fingers-3%E2%80%9D-away"><div class="level3">- <div class="li">Keep fingers 3” away from the needle</div>
- <div class="li">Power off and drain the motor before:</div>
    - <div class="li">Threading</div>
    - <div class="li">Replacing needles</div>
    - <div class="li">Removing jams</div>

- <div class="li">Tie back hair and scarves</div>
- <div class="li">Tuck sleeves behind elbows</div>

</div></div>### PROHIBITED MATERIALS

Thread Jams and needle breakage are critical concerns. Material that is too thick or rigid will lead to needle breakage.

Industrial machines **will not “step over” pins** in the fabric. Hitting one will break the needle and send broken parts into the hook below.

For those reasons, it is important to avoid:

<div class="section_highlight_wrapper" id="bkmrk-pins-in-the-fabric-a"><div class="level3">- <div class="li">Pins in the fabric</div>
- <div class="li">Abrasives</div>
- <div class="li">Paper and cardboard products</div>
- <div class="li">Plastics</div>
- <div class="li">Rigid Material (non-fabric)</div>

</div></div>### Initial Setup

Wipe down the machine and bed to clean up any oil or dust. Power on the machine. Ensure safety is not engaged, if the machine seems to be jammed, see [Troubleshooting](https://protohaven.org/wiki/tools/sewing_walking_foot/start#troubleshooting "tools:sewing_walking_foot:start ↵"). Wind the bobbin. Power off the machine to insert the bobbin and thread the machine. Ensure the needle is usable and appropriate for the material and thread. Set the needle position. Begin operation.

[![industrial_walking_foot_image5.jpg](https://protohaven.org/wiki/_media/tools/industrial_walking_foot_image5.jpg?w=580&tok=2f106e "industrial_walking_foot_image5.jpg")](https://protohaven.org/wiki/_detail/tools/industrial_walking_foot_image5.jpg?id=tools%3Asewing_walking_foot%3Astart "tools:industrial_walking_foot_image5.jpg")

#### CHECKING NEEDLE SIZE

<div class="section_highlight_wrapper" id="bkmrk-grab-a-needle-and-ab"><div class="level4">1. <div class="li">Grab a needle and about 12 inches of the intended thread</div>
2. <div class="li">Thread the needle</div>
3. <div class="li">Hold both ends of the thread, creating a 60 degree slope with one end to see if the needle is able to slide along the slope</div>
4. <div class="li">Reverse the process to see if the needle slides back</div>

</div></div>If the needle does not freely slide down the thread, the size may be too small. As a general rule, you’ll want the smallest size needle that will slide freely down the thread.

### WIND THE BOBBIN (Size M available in the Protohaven store)

[![](https://protohaven.org/wiki/_media/tools/imported/bobbin_winding.jpg?w=600&tok=5d1b17)](https://protohaven.org/wiki/_detail/tools/imported/bobbin_winding.jpg?id=tools%3Asewing_walking_foot%3Astart "tools:imported:bobbin_winding.jpg")

**Caution :** Be sure all object are off the table! The needle does not dis-engage like a consumer machine. It is preferable to remove the needle to avoid injury.

<div class="section_highlight_wrapper" id="bkmrk-check-the-bobbin-hou"><div class="level3">1. <div class="li">Check the bobbin housing for lint, brush it out if necessary.</div>
2. <div class="li">Pass the thread in order of (1) through (4)</div>
3. <div class="li">Lift the manual presser foot lever to raise the presser foot.</div>
4. <div class="li">Gently push the foot pedal until the bobbin is full—it shuts off automatically.</div>

</div></div>Please Note: If the bobbin is lop-sided, it can be used with caution, although it can affect tension.

<div class="section_highlight_wrapper" id="bkmrk--4"></div>### WINDING THE BOBBIN WHILE SEWING

For large projects, a second bobbin can be wound while sewing.

Thread the machine following the order of (1) through (13) as shown above.

Move the handwheel towards you, never away to get the top thread to take up the bobbin thread.

While holding the thread taught on either side, pass the thread between the tension discs, between the spring guide, and above the spring.

  
<span style="text-decoration: underline; background-color: rgb(45, 194, 107);"><span style="color: rgb(0, 0, 0); text-decoration: underline;">Insert "check spring click" photo here</span></span>

  
You will hear a light click as the thread crosses over a small hook on the inside of the disc. (just visible through the hole next to the spring)

</td><td class="col1 leftalign" style="width: 58.0252%; height: 214.562px;">Please Note: Do not adjust the check spring knob (#6)!   
  
Its function is to keep the thread taught while the take up arm moves to the highest position. Loosening the nut will disable the spring, causing the machine to come unthreaded or tangle while sewing.  
  
This spring should always have enough tension to pull the thread down.</td></tr></tbody></table>

The Check Spring is used to alter the amount of thread being pulled away from the thread spool above, used for very small or very large stitches or very thick material..

To adjust the stroke of the check spring, please make a Special Setup Arrangement with a Protohaven Staff Member to gain clearance in advance of use.
