Using the Saw in Bypass Mode
If you need to cut electrically conductive materials such as aluminum with this saw, you must operate the
saw in Bypass Mode to prevent the brake from activating. In order to operate the saw in Bypass Mode, the
safety system requires you to follow the procedure below to ensure that the saw is never placed in Bypass
Mode accidentally. If you are unsure whether a particular material is conductive, you can use the Material
Conductivity Test described on page 46.
Note: the saw will not start in Bypass Mode unless the brake cartridge is properly installed and all error
codes are cleared. It is not possible to “override” an error by starting the saw in Bypass Mode.
To Operate the Saw in Bypass Mode
a. Make sure the Start/Stop paddle is in the
OFF position and then switch the Main Power
switch to ON. Wait until the safety system
completes the initialization routine and the
system status code indicates the saw is ready
for operation.
b. Turn the Bypass Key clockwise and hold it
for at least 1 second (see Fig. 70). The green
LED will begin blinking slowly and the red
LED will flash once to let you know when the
1 second has elapsed.
Note: to prevent unauthorized use of the saw
in Bypass Mode, remove the Bypass Key
from the saw when not in use.
c. While still holding the Bypass Key turned, pull
the Start/Stop paddle out to the ON position.
The blade will start to spin.
d. Continue to hold the Bypass Key turned for at least 1 second after the motor starts—the red LED will flash
once again to let you know when the 1 second elapses. If you release the Bypass key before 1 second has
elapsed, the motor will stop and the “Push Start/Stop Paddle to OFF” error code will be displayed. If this
happens, switch the Start/Stop paddle to OFF and repeat this procedure from the beginning.
e. When you have completed your cut, push the Start/Stop paddle in to turn off the motor. The safety system
will remain in Bypass Mode until the blade comes to a complete stop. Once the blade has stopped, the
safety system returns to normal Standby Mode. The next time you start the motor, the safety system will be
active unless you repeat the procedure described above to start the motor in Bypass Mode.

WARNING! Never run the saw in Bypass Mode unless necessary to cut conductive materials. The
brake system will not activate when the saw is in Bypass Mode and a serious injury could result.
CAUTION! Always check the saw blade after cutting conductive materials. Sometimes
a shard of aluminum or other conductive material will become embedded on the end of
a saw blade tooth. If that occurs and the saw is started, then the shard could contact the
aluminum brake pawl and cause the brake to activate.
