(a) Trimmer saws shall not be run at a rim speed in excess of the manufacturer's recommended speed.
(b) Gang trimmer saws shall be guarded in front by a flat or round steel framework with a rigid metal screen or light iron bars attached thereto, or by wood baffles no less than 2 inches and securely bolted to a substantial frame or equivalent means.
(c) Front guards for a series of saws shall be set as close to the top of the trimmer table as is practical, considering the type of machine and the material being cut. The end saws on these trimmers shall be either guarded or railed off wherever employees are exposed to contact.
(d) The rear of the saws shall have a stationary or swinging guard of no less than 2-inch wood material, or equivalent, the full width of the saws and extending as much as possible to protect all persons at the rear of the trimmer.
(e) Push, pull, or two-saw trimmers shall be arranged so that the operator may make trim adjustment without coming close to the saw; or shall be provided with hood guards that cover the saw at all times, at least to the depth of the teeth. The guard should adjust itself automatically to the thickness of the material being cut, and remain in contact with the material at the point where it encounters the saw. That part of the saw located below the table shall also be enclosed.
(f) Automatic trimmer saws shall be provided with safety stops or hangers to prevent saws dropping below their sawing position.
(g) Saws shall not be propped up at quitting time, or for the convenience of the filers, until they have completely stopped. All controls shall be locked while the saws are filed.
(h) Trimmer feed chains shall be stopped while employees are on the trimmer feed table.
