I would first look for the simple problems before sending it in for service. This is part of an end-user adjustment, so it is fair to examine before service. (refer to the picture below).
- Look to see if the limit pin is down and inside the limit slot. The tip of the limit pin is smaller diameter than the body of the pin, and this rides in the slot. (If the smaller diameter tip is broken, then it should be returned for warranty.)
- If the limit pin is all the way down, but the saw is not being limited to 0-45, then check to make sure that the limit plate is not loose. There are 2 clamping screws (1 is visible in the picture), and these are accessible when the saw is at 0 (90) degrees. (If they are loose, you will have to re-calibrate the saw for 0 (90) degrees.)
- If the limit pin is not engaging in the slot, look to see if it is centered over the slot. If it is not centered over the slot, it can't drop into the slot, and you will have to re-calibrate the saw for 0 (90) degrees. During that calibration, make sure the pin is fully depressed and in the slot before tightening the 2 screws.
I have not completed the calibration process myself, but here is a quick guess on how to do it. Even though the actual adjustment is different, refer to the older TS55EQ manual (page 11) for how to determine if your cut is perpendicular to the workpiece.
Supplemental TS55EQ Manual
1) With the saw at 0 degrees, loosen both clamping screws that secure the limit plate. (There is a small hole in the plastic cover to access the upper/front screw at 0 degrees.) Cycle the saw between 0 and 45 degrees to ensure the limit pin is in the slot.
2) Using the procedure in the old manual, tweak the saw until you get a perfect 90 degree cut. Once you have a perfect 90 degree cut,
do not loosen the bevel adjustment knobs.
3) Notice on the front of the saw there is a small rectangular hole right in front of the limit pin. It's a little blurry, but you can see this hole (notch) in the picture below. With a small screw driver, gently press against the tab of the limit plate (don't press too hard). This will bias the limit plate against the limit pin. While pressing against the tab, carefully tighten the 2 screws (leave the bottom/rear screw just a little bit loose, but the upper/front screw firmly tightened).
4) Carefully bevel the saw to 45 degrees and make sure the limit pin slides freely in the slot. Cycle the limit pin up and down to make sure it falls into the slot without hitting the slides of the slot.
5) If the limit pin is not centered in the slot at 45 degrees, return the saw to 0 degrees and loosen the lower/rear clamping screw (do not loosen the front screw). There is a screwdriver slot on the side of the limit plate next to the rear clamping screw. Use this to tweak the limit plate to center it on the limit pin.
6) Slightly tighten the lower/rear screw, and check your results. Repeat the step until the limit pin is centered in the slot at 45 degrees.
7) firmly tighten both screws.
