Swing Stop

™ 

Owner’s Manual

Cutting numerous pieces to the exact length without measuring, is 

easy. Gently press the end of the board opposite the blade against 

the side of the Stop Arm; as shown in 

Figure 1.

The Swing Stop

 is intended for use only with the following Kreg products: KMS7712 and 

KMS7414 Top Trak, KMS7704 Heavy-Duty Trak, KMS8000 Precision Trak & Stop Kit, and 

KMS7102 Precision Miter Gauge System.

General Safety Rules

•Read this manual and these safety guidelines. When using the Swing Stop™ as an 

accessory to another Kreg product and a power tool, read, understand, and follow 

the Kreg product manual and the tool manufacturer’s safety guidelines.

 Learn the 

applications and limitations of the tool as well as the hazards specific to it. Operating the power 

tool before understanding safe and proper use could result in personal injury.

•Ensure that the T-knob securing the Swing Stop™ to the Trak or fence is tight prior to 

starting the power tool.

•Keep hands away from a moving blade or bit when operating the machine.

 Never reach 

near a moving blade or bit to clear debris. Turn off the power tool and wait for the blade or bit to 

come to a complete stop.

•Always support long boards on both the infeed and the outfeed ends.

•Always securely hold workpieces against the machine table and miter gauge or fence.

•This Swing Stop™ is designed for a specific application.

 Do not modify and/or use it for 

any other application. If you have questions about the miter gauge, DO NOT use it until you 

contact Kreg Tool Company and receive advice.

SAVE THESE INSTRUCTIONS.

These stops can be secured anywhere along the Trak. The Swing 

Stop

TM

 is designed to raise out of your way automatically, when a 

board is pushed against the front; as shown in 

Figure 2.

The Stop Arm rests on top of the workpiece until the board has been 

withdrawn. When the board is removed or moved to the side of the stop, 

the arm drops down and is again ready for use.

The Stop Arm can be positioned on either side of the base which is 

secured to the Top Trak with the T-Knob. (

The Stop Arm should be 

positioned between the base and the saw blade; as shown in Figure 2.)

The distance between the blade and the Stop Arm is measured using 

the lens and tape attached to the Top Trak. (see the opposite side of this 

page for more instructions.)

About the Lens Cursor

Our stops feature an adjustable Lens Cursor, similar to the lens on a 

quality tablesaw rip-fence. The lens is a clear material, except for a red 

line (cursor) on the bottom of the lens; as shown in Figure 3. The Lens 

Cursor is adjustable to fine-tune the stop, and is secured in place with 

the Lens Screw. The Lens Cursor can be aligned to either side of the 

Stop Arm.

The cursor makes it easy to read the tape lines and compensate for 

variations in blade thickness and imperfectly positioned tape.  Because 

the Lens Cursor protrudes 

3

8

″ from the stop (as seen in Figure 4), the 

self-adhesive tape on a Kreg precision measuring component must be 

placed 

3

8

″ closer to the saw blade for the lens to work properly.  

After you have correctly set the Swing Stop

TM

 for your particular set up, 

make a few practice cuts to ensure its accuracy.  First, set the Swing 

Stop

TM

 at 20″ (or any length you desire) and make a cut.  Check the 

stock with your tape measure to test the accuracy of the cut. Make 

adjustments to the Lens Cursor as necessary.  Do this by loosening 

the Lens Screw and gently pulling or pushing the Lens Cursor to the 

desired location before tightening the Lens Screw again.  Make a 

second cut at 18″ (or any length shorter than the original) and test the 

accuracy again.  Repeat this process as necessary.

The design of the Swing Stop

TM 

allows it to work with the addition of a 

sacrificial board attached to the fence of our Miter Gauge. Sacrificial 

boards afford a renewable surface to support the workpiece, resulting in 

a smooth crosscut that minimizes tear-out.

The sacrificial board can be constructed from any material  you choose. 

The board must be 

3

4

″ thick and may not exceed 2

5

8

″ in height. Choose 

a length that best suits your application. Attach the board to the Miter 

Gauge Fence with 

1

4

″ diameter, 

3

4

″ long bolts and nuts. Drill 3-4 holes, 

with counter-bores, large enough to facilitate the bolt, nut, and washer. 

Using this arrangement, the sacrificial board may be moved along the 

fence independently of the measuring tape attached to the fence. This 

eliminates the need to recalibrate the measuring system each time you 

want to renew the backing surface.

The design of the Swing Stop

TM

 makes it fully compatible with the 

addition of a sacrificial board to the aluminum fence. A groove (breakline) 

has been incorporated into the base of the Swing Stop

TM

 Arm. This 

breakline has been added to provide a simple means to shorten this 

portion of the Swing Stop

TM

, for use with a sacrificial board. If you intend 

on using a sacrificial board, remove the breakaway section of the stop, 

as shown below. We suggest using a file or sandpaper to smooth the 

rough edge of the Swing Stop

TM

 after breaking it away.

Once the Swing Stop

TM

 has been altered, it can only be used with a 

sacrificial fence on the Miter Gauge. It will not work correctly if used 

without a sacrificial fence.
