Description

Sergers preform a type of stitch known as overlock stitching. An overlock stitch is a type of stitching that sews over the edge of one or more pieces of fabric. Sergers also have the ability to cut off the excess edge as it is fed through the machine. This type of stitching is useful for edging, hemming, and seaming. This process will create a clean edge of your fabric that will not fray.

The Janome MyLock 634D features 2 needles and a choice of 2,3, or 4 thread overlocking stitching. The color-coded thread guiding makes threading simple and easy to follow. The MyLock 634D allows the user to easily switch from overlock stitching to rolled hemming without needing to change to needle plate. Some of the key features of the MyLock 634D are a tension release device, easily accessible lower looper guides, changeable thread guide, easily retractable upper knife, adjustable foot pressure, and more.

Documentation

Terminology

Rip - Cuts made along the length of the wood.
Cross-cut - Cuts made across the grain along the shorter side of the wood.
Push stick - A piece of wood or plastic used to push the wood being cut through the blade while keeping fingers away from the blade.
Fence - A guide for measuring the cut and guiding the wood.
Riving Knife - A flat metal device that mounts behind the saw blade. This device prevents material from closing up on the blade and causing a dangerous condition called a material kickback.
Sled - A fixture that is placed on top of the table to assist with cross cuts. The sled keeps material perpendicular to the blade and helps to prevent the blade from kicking back material.

Training

Operation

All information on this specific machine can be found in the User Manual

A simple intro to serging:

Sergers are great for adding zippers into your project. Here is a helpful video to lead you through the process.

Demonstration

Demonstrate you can safely setup the saw and rip a board. You will then proceed to cross cut one of the remaining pieces. Remember to set the blade height so it is protruding less than 1/4" out the top of material for less exposure. When performing a rip cut the fence is used to guide the lumber into the blade. You want to make sure that the distance between the fence and blade is the width of desired cut. Mark the edge of the material when doing a cross cut so you can align the material with the blade in the sled. You can also use a miter gauge for making cross cuts but make sure the material is long enough and well supported.

General Procedure

Safety

There are several hazards you need to be aware of when using a Serger.

Never use a bent needle.
Keep fingers away from the needle and moving parts.

Certification

Foxtale Course

Troubleshooting

If the blade appears to need sharpening ask the tech to change out the blade.

A sign of a dull blade is as follows:

1. Burning of material

2. More resistance when cutting

3. Rough cut edges

4. Increased cutting noise

5. Increased motor noise

Maintenance

General maintenance

Keep the saw clean and use the dust collector. There are several lubrication points on the saw that need to be checked by the tech.

-'''Rip Cut'''
-. Ensure that the material you are cutting has at least one straight edge and no nails or foreign objects. The straight edge will slide against the fence when ripping.
-. Measure the width of the board and determine the width of cut desired.
-. Lift the locking handle on the fence and slide the fence to the desired cut width using the scale. Make sure you use the scale for the correct side of the blade.
-. Lock the fence by pressing down on the locking handle.
-. Use the elevation handle on the front of the saw to set the height of the blade approximately 1 tooth above the height of the material by placing the material next to the blade as a guide. This limits the exposed blade.
-. Turn on the main power switch on the front of the saw and the dust collector. The green light on the saw will flash and turn solid green when the saw is ready.
-. Make sure nothing is touching the blade. Turn on the saw by gently pulling on the red start paddle switch located on the front of the machine. The paddle switch is also the off switch when pressed.
-. Line up the flat side of the material with the fence without touching the blade. The fence is a guide and the material should be pressed firmly into the fence as well as down on the table. If the board is warped make sure that curved side is face downward.
-. Slowly feed the material in towards the blade while keeping your fingers at least 6" from the blade. Use a push stick to keep fingers away from the blade.
-. Make sure you keep a firm hold on the material and do not stop feeding the material until it has passed beyond the blade.
-. It is helpful to have someone assisting on the back side of the saw to help hold material being fed off the table. Make sure the person helping does not pull on the material.
-. When the saw cut is complete, press in on the paddle switch to turn off the saw and lower the blade below the table to keep anyone from accidentally cutting themselves.
-'''Cross Cut'''
-. Move the fence off to the side by lifting the brake handle and sliding the fence off to the side.
-. Place the cross cut sled on the table by aligning the table slots with the rails on the sled.
-. Slide the sled over the blade and use the material to set the blade height using the blade height handle on the front of the saw. The blade should be roughly one tooth taller than the top of the material.
-. Place the material flat edge against the back of the sled and align the material with the edge of the blade.
-. Once the blade is clear pull the red paddle switch to turn on the saw.
-. Slide the sled forward to cut through the material at the desired location.
-. Slide the sled back to you so it clears the blade.
-. Power down the saw by pressing the red paddle switch located on the front of the machine.
-. Lower the blade below the table using the crank handle on the front of the machine.
-. Reset the space by cleaning up any dust, turning off the equipment, and lowering the blade below the table to keep anyone from accidentally cutting themselves.
