Installing a Brake Cartridge
To install a brake cartridge, the above process is reversed. Align the mounting holes in the cartridge with the
pivot pin and positioning pin in the saw. Slide the cartridge onto the pins until the cartridge rests against the
mounting bracket. The cartridge will automatically align with a computer cable mounted in the saw.
Next, insert the cartridge key into the hole in the cartridge housing (see Fig. 78 on page 60). The key shaft has
a ridge that must be aligned with a channel in the hole. As a result, the key can only be inserted into the hole
when the red handle is pointing toward the brake pawl. Insert the key fully into the hole and rotate the key 90°
counter-clockwise to lock the cartridge in place. The key will not rotate unless it is fully seated against the side
of the cartridge housing and the cartridge housing is pressed against the cartridge mounting bracket.
Once the key is rotated to its locked position, it cannot be removed and the cartridge will be locked in place.
Rotating the key to the locked position also actuates a switch inside the cartridge that signals to the safety
system that the cartridge is correctly installed and locked in place. The system will not allow the saw to start if
the switch is not actuated. If you attempt to turn on the saw when the key is not in the locked position, the LED
lights on the switch box will flash a status code indicating the key should be turned to ON. Turning the key to
ON means turning the key to the locked position.
To complete the installation, the brake cartridge must be correctly positioned relative to the blade or dado set.
Once the brake cartridge is installed, fully rotate the blade guard clamping handle counter-clockwise to lock
the spreader or riving knife in place. Next, install the blade or dado set as described on page 29, and adjust the
brake position as described on page 30. Rotate the blade by hand at least one complete revolution to ensure
that the blade does not contact the brake.
WARNING! Always check, and if necessary, adjust the position of the brake after changing
the brake cartridge or the blade. An improperly positioned brake could increase the time
required to stop the blade in the event of accidental contact, or cause the brake to actuate
unexpectedly if the blade comes into contact with the brake.
