The SawStop Tablesaw is a level 3 tool in the Wood Shop Area . Which requires individual certification before use.

The saw cannot be turned on without scanning the RFID card of a certified member in the TESLA system.

Attend an in-person, hands-on SawStop class ($50)

Getting Started

By using this tool, you accept responsibility for safe operation and agree to pay for brake and blade replacements required due to false activation of the safety system.

Powering on the SawStop

Before using the SawStop table saw, read the user manual and become familiar with the saw's controls and features.

The SawStop table saw will not turn on without scanning the RFID door card of an authorized user.
Scan your door card on the TESLA box to enable the saw and wait for the ready-to-operate lights to turn green.
Use the paddle switch to turn on and off the blade.
After use, drop the blade into the cabinet, clean the saw, and log off.

Operating PPM's SawStop Table Saw

Do not make adjustments to the saw, adjust the fence, or change the blade without shop Captain approval.
If the brake trips, contact the Woodshop Captains.
Ensure the blade guards are kept clean and free of debris.
Use dust collection.
Report any damage or issues immediately.

Operating any Table Saw

Make sure you have no loose clothing, jewelry, or hair that will be anywhere near the blade.
Always wear appropriate personal protective equipment, including eye and ear protection, and a dust mask.
Always use the blade guard and splitter (riving knife) to keep the wood from binding and kicking back during the cut.
Always be familiar with the location of the Emergency Stop Button, and practice reaching for it from your cutting stance to commit the motion to muscle memory.
Always ensure the saw is off before making any adjustments to angle or height of the blade.
Always use the folding outfeed table when ripping plywood or long stock.
Always use push sticks and push blocks to keep your hands at least 4" away from the blade.
Never reach over the blade or make contact with the blade while it is in motion.
Never use the zero clearance insert on angled cuts. It is for 90 degree cuts only.
Never use the miter gauge and the rip fence at the same time.
Keep the blade height set between 1/8 to 1/4 inch above the workpiece.
Do not cut too close to the fence.
No dado cuts. The SawStop requires a special cartridge which we do not have.

Avoiding Kickback

Kickback can occur when ripping boards. Keep to one side of the blade or other depending on the cut you are making. Stay away from standing directly behind the blade.
You must always use the rip fence, miter gauge, or crosscut sled. Absolutely no free cuts with the tablesaw.
Use the blade guards and riving knife.
Miter gauge must be used on the right of the blade when bevel cutting.

Cleaning up and Shutdown

Lower the blade into the cabinet after use and clean the saw.
Clean the blade guards after each use with compressed air.
Inspect blade, and notify shop Captain if the blade needs to be cleaned.
Dust off the surface and clean around the base after each use.
Close the dust door below the table surface (?)
Don’t leave any scraps - dispose of them in the bin or dumpster.
Put all accessories (moisture meter, metal detector, miter gauge) back in the appropriate location.
The SawStop should be perfectly clean and ready for the next user when you are done.
Log out and clean up after each use or risk losing access to the saw.

SawStop Captain Duties

Maintenance Inspections

Keep the saw's blade and guards clean and free of debris to ensure optimal performance and safety.
Check the tightness of all bolts, screws, and other fasteners regularly to ensure that the saw remains securely in place.
Replace worn or damaged parts as soon as possible to maintain the saw's performance and safety.
Regularly inspect the saw for any signs of wear, damage, or other issues that could impact its performance or safety.

Hands-on SawStop class

Instructors of the hands-on SawStop class will cover the following.

How to check material for conductivity and avoid false triggers.
The normal blade guard is used for rips and crosscuts.
The instructor will show you how to install the riving knife for non-thru cuts or rabbets.
The limit rod should remain on the blade guard.
The kickback pawls can be enabled or disabled depending on your needs.
The blade height should be set so that the blade is 1/8 to 1/4 inch above the wood piece.

SawStop Flesh Detection

The 5HP SawStop Industrial Cabinet Saw is a high-quality saw that is designed for safety and performance.

It features a flesh detection technology that can quickly stop the blade in the event of accidental contact with a user's skin.

In the event of flesh detection, a single use cartridge fires and seizes the blade before the user is injured.
Both the cartridge and blade must be replaced before the SawStop can be used again.

Avoiding False Triggers

Although uncommon, it is possible to have a false flesh detection. Users are responsible for the expense of brake and blade replacements required due to false activation of the safety system (about $150).

False triggers are caused by conductivity. One way to check if your material is conductive is to hold it against the blade with the saw off and look at the indication lights. If red, it will trigger the blade brake. If green, that part of the material is unlikely to trigger.

Moisture in the Wood can cause false triggers in the SawStop's flesh detection technology. To avoid false triggers from moisture, it's important to properly test the moisture content of the wood before cutting and to ensure that the moisture content is below 10%. Here are the steps to properly test the moisture content.
1. Use the moisture meter: You will need a moisture meter to accurately measure the moisture content of the wood. There are a variety of moisture meters available, ranging from simple pin-style meters to more advanced meters with digital displays.
2. Test several locations: It's important to test several locations on the piece of wood, as the moisture content can vary from one area to another. Aim to test at least 3-4 different spots on each piece of wood.
3. Take readings: Place the moisture meter probe on the surface of the wood and take a reading. Repeat this process for each of the test locations.
4. Evaluate the results: Compare the readings from each location to determine the average moisture content of the wood. Ideally, the moisture content should be below 10% to reduce the likelihood of a false trigger. If the moisture content is higher than 10%, allow the wood to dry out further before cutting it on the SawStop table saw.
  - It's important to note that moisture meters are not foolproof and can sometimes give inaccurate readings. However, they are still a valuable tool for monitoring the moisture content of wood and reducing the risk of false triggers.
  - By properly testing the moisture content of the wood before cutting and ensuring that the moisture content is below 10%, you can reduce the likelihood of a false trigger due to moisture and ensure a safe and successful cutting experience with the SawStop table saw.
Laser-Cut/Engraved Wood can cause false triggers and should not be used on the SawStop table saw. The carbon is conductive and can trigger the cartridge
Treated Lumber can cause a false trigger because of the copper used in the treatment.
Metal - Hitting a nail, screw, or staple will trigger the cartridge and you are responsible for the $150 replacement cost. Use the metal detection wand to ensure there is no metal in your wood! However, this is no guarantee as non-ferrous metals like aluminum can trigger the flesh detection system. (ie: insulating Styrofoam with a aluminum foil lining)

Access to the flesh detection bypass keys may be requested from the Executive Director.
