A saw has a base assembly, a saw assembly pivotally mounted on the base assembly, a motor mounted within the saw assembly, and a drive spindle rotatably driven by the motor via a drive mechanism. The drive mechanism has a rotatable output shaft, a first drive wheel mounted on the output shaft, a rotatable intermediate shaft, a first driven wheel mounted on the intermediate shaft, a first drive belt wrapped around the first drive wheel and first driven wheel for transfer rotary motion of the output shaft to the intermediate shaft, a second drive wheel mounted on the intermediate shaft, a second driven wheel mounted on the drive spindle, and a second drive belt wrapped around the second drive wheel and second driven wheel for transferring rotary motion of the intermediate shaft to the drive spindle.

A saw comprising a saw assembly including an upper saw blade guard and a motor which can be actuated by an on-off switch arrangement and can rotatingly drive a saw blade mounted on the assembly. The saw assembly is pivotably mounted on a saw table such that the saw assembly can be lowered towards the table to cut a workpiece resting on the table. The saw includes a lower moveable guard which is pivotably mounted to the upper guard so that the lower guard is moveable to expose a saw blade mounted on the assembly and a guard lock arrangement is used for locking the lower guard over a saw blade mounted on the saw assembly when the saw is not in use. The guard lock arrangement includes a guard lock lever moveably mounted to the saw assembly. The guard lock lever includes a locking portion and a switch actuation portion such that in an off-position of the guard lock lever the locking portion engages the lower guard to prevent it from moving and in an on-position of the guard lock lever the locking portion is disengaged from the lower guard so that the lower guard is free to move to expose the saw blade and the switch actuation portion engages the on-off switch arrangement.
