Frequently Asked Questions - KMA4100 Kreg

What types of circular saws are compatible with the KMA4100?

This product is designed to be used only with portable circular saws. It is not suitable for routers, jigsaws, or other tools.

How do I make an initial kerf cut on the cutting board?

Set the cutting depth to about 5 cm. Align the saw base on the rails, start the saw and let the actuator panel open the blade guard. Cut through the front panel and the Sure-Cut™ board until the center of the blade, then turn off the saw.

How do I make a precise 90° cut?

Mark the length on the workpiece, align the mark with the edge of the kerf. Use the clamps to hold the workpiece. Place the saw on the rails, start it and cut until the center of the blade reaches the Sure-Cut™ board. Turn off the saw on the rails and remove the workpiece.

Can I cut angles other than 90°?

Yes, you can make angle cuts from 0° to 45°. Set the adjustable guide to the desired angle line on the wings. Ensure the end of the workpiece is away from the Sure-Cut™ board to avoid blade binding.

How do I handle long workpieces?

Unfold the support wings. For very long boards, remove the detachable blocks and place them near the end of the workpiece for better support at the entry and exit.

Is it necessary to secure the cutting station to the workbench?

The Sure-Grip™ pads provide good grip. However, if you want a more secure attachment, you can screw the station to your workbench through the holes in the side rails (screws not included).

How do I maintain the crosscut station?

Regularly remove dust and debris from all surfaces, including under the station and on the non-slip pads. This ensures safe and accurate use.

What if cutting accuracy decreases?

Check that all parts are properly tightened. If the problem persists, contact Kreg customer service for advice or to replace cutting surfaces like the Sure-Cut™ board.

What are the main safety instructions?

Always wear recommended personal protective equipment. Do not cut pieces that are too small. Keep hands away from the cutting area. Do not attempt bevel cuts. Make sure the station is stable before each cut.

Technical diagram of a mechanical device with labeled parts H, E, and CC, showing internal components and mounting hardware.

3 Attach the Guide Rails

WARNING Ensure rails are installed per the instructions below to keep your hand a safe distance from the rotating blade while cutting.

a. Ensure your saw blade is as centered as possible on the cutting surface. To accomplish this, set your fixed saw guide rail (B) on the front and back boards (H and E) on the side opposite of your blade (as shown).
b. Set your adjustable saw guide rail (C) on the front and back boards (H and E) to the width of your saw base plate.
c. Position the saw so that the blade is as centered as possible, and secure the fixed saw guide rail (B) to the corresponding holes in the front and back boards (H and E).

Note Depending on your saw type, this may result in the fixed rail being opposite the picture shown. The goal is to have your saw blade positioned as centered as much as possible in the cutting surface.

Operation

WARNING Always make sure the Crosscut Station is secured to prevent movement while cutting.

Use the procedures in this section to begin using your Crosscut Station. The following examples show placement for a left blade saw.

Sure-Grip™ feet help to hold Crosscut Station in place while cutting. If a stronger hold is needed, you can affix the station to your work bench using two screws (not provided) and attaching through the holes in the side tracks, as shown by the arrows on the right.

Make your Kerf Line Cut

a. Before you make your kerf line, set the saw cut depth to 2" (just enough to score the bottom cut surface of the cutting base (A)).
b. Align the base of your saw to the rails behind the front blade guard actuator board (H).
c. Start your saw, and while keeping your saw flat to the guide rails, allow the front blade guard actuator board (H) to engage the blade guard while making a cut through it.

WARNING Do not try to lower the saw into the cut by using one hand to open the blade guard. Doing so could result in a saw kick back and serious injury.

ATTENTION Stop the saw and allow the blade to come to a stop once the center of the saw blade has cut through the Sure-Cut™ back board (E). Pushing well beyond the rails can cause a widening of your kerf line (1) and could affect your cut accuracy. See the images below for the proper stopping point as noted by the X symbol.

Make a 90^ Cut

a. Mark your workpiece to the desired length (2).
b. Align the mark (2) with one edge of the saw kerf line (1), making sure that the workpiece is aligned to the blade so the blade will cut through the cutoff (waste) portion of the board (marked with an X in the illustration), and not through the side of the workpiece you want to keep.
c. Use the clamps (F) to help hold the workpiece on either side of the rails. In addition, use your hands to hold your workpiece outside of the cutting surface.

WARNING Do not reach behind the saw blade or the fence with either hand to hold down or support the workpiece, remove wood scraps, or for any other reason while cutting. The spinning saw blade may be so close to your hand that you may be seriously injured.

d. Align the front of your saw base to the rails and start the saw. Move the saw through the cut until you have cut entirely through your workpiece (center of the blade at the Sure-Cut™ back board).
e. Stop the saw and release the trigger while the saw is still on the rails. Once the motor has stopped, lift your saw and remove the workpiece and cutoff piece from the cutting station. This step keeps your kerf line true to your saw.

WARNING Do not cut pieces that are too small to be securely held or clamped.

WARNING Always secure the workpiece with a firm grip ensuring your hand stays outside of the cutting area as designated by the symbol.

Cut Different Angles

ATTENTION The width of the board you will be able to cut will vary depending on your saw and where you position the fence.

ATTENTION If you are not cutting the angle on the end of the board, cut to length at 90° before cutting the angle.

a. Position the front of the adjustable fence (G) to the desired angle line on the material support wings (D) on either side of the cutting station and tighten in place.

WARNING Position the end of the workpiece away from the Sure-Cut™ back board to avoid binding of the blade and kickback.

b. Tighten the fence in place and then follow the steps and precautions in Make a 90° Cut for making the cut.
