SawStop 10” Contractor Saw 13
The SawStop Safety System ®
10. Never install the blade backwards. The brake might not stop a blade that is installed backwards.
11. 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.
12. Do not use table inserts, guards, fences or other devices which have metal parts that may come into contact
with the blade. Any metal part that contacts the blade may cause the brake to activate. All SawStop ® accessories
are specifically designed to prevent metal contact with the blade.
13. Do not unplug or disconnect the saw from electrical power before the blade has stopped spinning. If the power
is interrupted while the blade is moving, the safety system will not be active and therefore the brake will not
activate in the event of accidental contact. You may receive a serious injury if you contact the spinning blade
while the electrical power has been interrupted.
14. Do not replace the arbor belt with a non-SawStop ® belt. The SawStop ® arbor belt is custom designed to dissipate
static electricity that may build up on the spinning blade which could cause a false activation of the brake.
15. Never reach under the blade while it is spinning. In the event the brake is activated, the retraction of the blade
may cause a serious injury if you contact the bottom of the blade.
16. Never touch the arbor, arbor pulley, arbor nut or arbor washer when the blade is spinning because you may
receive a serious injury. These parts are all electrically coupled to the blade and the brake will activate if contact
with these parts is detected.
17. Never attempt to disable the SawStop ® safety system or modify the electrical wiring of the saw in any way. Any
change or modification or disablement of the safety system or other wiring could result in a serious injury and
will void all warranties.
18. Never attempt to repair, adjust, modify or otherwise service a brake cartridge. There are no user-servicable
parts inside the brake cartridge. The brake cartridge is permanently sealed against dust and other contaminants.
Destruction, removal, or alteration of this seal voids all warranties.
19. Do not remove the dust shroud because a large portion of the blade will be exposed. If you contact the blade
under the table, the blade may retract toward you and cause a severe injury.
20. Wet, pressure-treated wood may cause the brake to activate. The chemicals used to pressure treat wood often
contain large amounts of copper, which is conductive. When pressure-treated wood is wet, the combination of
copper and water substantially increases the conductivity of the wood. Therefore, allow wet pressure-treated
wood to fully dry before cutting. Typically, the wood will be sufficiently dry if left unstacked in a dry location for
24 hours. If you must cut wet pressure-treated wood, you can make several cuts in the wettest piece(s) using
the Bypass Mode to test whether the wood is too wet. See page 55 for instructions on using Bypass Mode and
page 46 for information on testing the conductivity of a material. If the test indicates the wood is too wet to cut with
the safety system active, you must either allow the wood to dry or make the remaining cuts in Bypass Mode.
21. The SawStop safety system is designed for use with standard 10 inch blades with kerfs from 3 ⁄
32
inch to 3 ⁄
16
inch.
Blades with kerfs much thinner than 3 ⁄
32
inch should not be used because those blades might not be strong enough
to withstand the force applied by the brake when it activates. As a result, those blades might deform and stop more
slowly in the event of an accident, resulting in a more serious injury. Blades with kerfs much thicker than
3
⁄
16
inch
are heavier than standard 1 ⁄
8
inch kerf blades. Therefore, those blades should not be used because they may stop
more slowly than standard blades in the event of an accident, resulting in a more serious injury. Similarly, stacks of
two or more 10 inch blades should never be used on your SawStop saw as the combined weight of the blades
may be too heavy to stop quickly. If you need to use a blade with a kerf thicker than 3 ⁄
16
inch, use an 8 inch dado
set with the optional Sawstop 8 inch dado brake cartridge. The dado cartridge is designed for use with 8 inch
dado sets up to 13 ⁄
16
inch wide.
