Part 25 Tools, Equipment and Machinery

Section 381 Cut off saws

Workers may sustain hand injuries when using cut off saws in a variety of ways including

(a) when the blade coasts or idles,
(b) when a worker tries to remove a sawed section of board or a piece of scrap, or
(c) when a worker measures boards or places them in a position for the cut.

A worker may also be struck by the saw if it bounces forward or the return device falls.

Hand operated cut-off saws (other than radial arm saws) must be equipped with a device that returns the saw automatically to the back of the table when the saw is released at any point in its travel. This prevents the saw from being left in a hazardous position.

Radial arm saws are exempt from this requirement because of the occasional need to lock these saws into a particular position for ripping and mitering.

A limit device must be in place to prevent a swing or sliding cut-off saw from travelling past the outside edge of the cutting table. This may be done by using a limit chain or other device that prevents the saw from swinging beyond the back or front edges of the table. Another device should keep the saw from rebounding from its idling position.

The limit device prevents the worker from operating the saw in an unsafe position (see Figure 25.7).
