Always keep blades and cutting edges sharp. Perform maintenance, blade changes, and adjustments only when tool is unplugged or properly locked out. Make sure that blades, bits, and accessories are properly mounted. In addition, make sure all locking handles and clamps are tight before using the tool. There seem to be as many hazards created by moving machine parts as there are types of machines.
Safeguards are essential for protecting workers from needless and preventable injuries.
When the operation of a machine or accidental contact with it can injure the operator or others in the vicinity, the hazards must be either controlled or eliminated. These components include flywheels, pulleys, belts, connecting rods, couplings, cams, spindles, chains, cranks, and gears. These can include reciprocating, rotating, and transverse moving parts, as well as feed mechanisms and auxiliary parts of the machine. A wide variety of mechanical motions and actions may present hazards to the worker. These can include the movement of rotating members, reciprocating arms, moving belts, meshing gears, cutting teeth, and any parts that impact or shear.
