Ripsaws and crosscut saws. Enclose the portion of the saw above the table with a self-adjusting guard (Fig. 1). The guard must adjust to the thickness of the material being cut and remain in contact with it. Hinge the guard so that the blades can be easily changed.
Attach a brake to the motor’s arbor to stop the saw from coasting after it has been cut off, or have the operator remain at the saw station once the motor is shut off until the blade stops turning.
Use a push stick for small pieces of wood and for pushing stock past the blade. For more complete information
