SawStop JSS-120A60, Owner'S Manual, Page: 19 / 100

The SawStop safety system does not interfere with your use of the saw. You can still make all the cuts (
see
page 74
) that you can with ordinary saws, including 0° to 45° bevels, non-through cuts, and Dado cuts
(with the optional Dado brake cartridge and the optional Dado table insert).
Your SawStop saw operates differently than ordinary table saws, and there are a few important points to
keep in mind as you use the saw.
1)
Do not rely on the SawStop safety system to protect against unsafe operation. Although the system
is designed to react and stop the blade very quickly in the event of accidental contact, it cannot react
until contact is detected. This means that you may receive at least a minor injury even with the SawStop
safety system. Therefore, always use safe operating practices, and use the blade guard, push stick and
other safety devices whenever possible. The SawStop safety system, like the airbag in a car, should be
considered as a last measure to minimize injury when all other safety practices and devices have failed
to prevent an accident.
2)
In the event of contact, the blade will be stopped in about 3–5 milliseconds (coarse-toothed blades stop
more quickly than fine-toothed blades such as plywood blades). Therefore, the seriousness of the injury
incurred will depend on the speed at which a person’s hand or other body part is moving toward the
blade. For example, if a person’s hand is moving toward the blade at 1 ft./sec., then the depth of the
cut will be approximately 1/16 inch (1 ft./sec.* 0.005 sec. = 0.005 ft. or 1/16 inch). At faster speeds, the
cut will be proportionally deeper. Therefore, it is possible to be seriously injured even with the SawStop
safety system.
3)
Do not operate the saw in Bypass Mode unless you are cutting electrically conductive material. (
see
page 49
) When Bypass Mode is engaged, the SawStop safety system will not activate the brake if
contact is detected and a serious injury could result if you contact the blade.
4)
The motor cannot be started without a blade installed. Since the safety system disables the motor if the
blade is spaced too far from the brake, a missing blade will be detected as a blade-to-brake spacing
error and the motor will be disabled.
5)
Blades:
You can use any standard 10 inch saw blade or 8 inch Dado set with your SawStop saw (
see page
70
), although the following precautions should be observed:
f)
Never attempt to use a blade other than a single 10 inch blade with the standard SawStop brake
cartridge. Never attempt to use a Dado set or blade other than an 8 inch Dado set with the
SawStop Dado cartridge. The use of smaller diameter blades with a brake cartridge designed for
larger blades could result in a serious injury because the brake cannot be positioned correctly to
stop the smaller blades.
g)
Never stack Dado blades thicker than 13/16 inch ( see page 70 ). The 8 inch Dado brake cartridge
is not designed to stop Dado stacks thicker than 13/16 inch.
h)
Do not use molding heads. The use of molding heads could result in a serious injury because
neither the standard brake cartridge nor the Dado brake cartridge is designed to stop a molding
