The machine shall be complete, so that when connected to the utilities identified herein, it can be used for any function for which it is designed and constructed.

3.1.1 Measuring/Indicating Devices: All measuring and indicating devices such as dial indicators, pressure gages, temperature indicators, depth stops, and other similar devices used on the machine shall be graduated in dual, inch-pound units. Marking on all measuring and indicating devices shall be permanently and legibly engraved or etched on a non-glare background. All dials and other type indicating devices shall be securely mounted in place. Such devices shall be located so as to allow reading from the operator’s normal workstation.

3.1.2 Safety and Health: Covers, guards, and other safety devices shall be provided for all parts of the machine that present safety hazards. The safety devices shall not interfere with the operation of the machine. The safety devices shall prevent unintentional contact with the guarded part and shall be removable to facilitate inspection, maintenance, and repair of the parts. All machine parts, components, mechanisms, and assemblies furnished on the machine shall comply with all of the requirements of 29 CFR 1910.

3.1.3 Prohibited Materials: Asbestos, mercury, lithium or polychlorinated biphenyl (PCB) shall not be used in any part or component of the system.

3.1.4 Environmental Protection: The machine shall be so designed and constructed that under the operating, service, transportation and storage conditions described herein, the machine shall not emit materials hazardous to the ecological system as prescribed by federal, state, or local statutes in effect at location of installation.

3.1.5 Nameplate: A corrosion resistant metal nameplate identifying the machine shall be securely attached to the machine. The nameplate shall contain the following information:

Nomenclature Contractor’s Name Contractor’s Model Designation Contractor’s Serial Number Power Input (volts, total amps, phase) Date of Manufacture

3.2 Construction: The hydraulic shear machine shall be constructed of parts which are new, without defects, and free of repairs. The machine structure shall be capable of withstanding all forces encountered during operation of the machine at its maximum rating and capacity without distortion. Processes such as welding, plugging, or filling with solder or paste shall not be used for reclaiming any defective part(s). All screws, pins, bolts, and other fasteners shall be installed in a manner as to prevent change of tightness. The machine shall be manufactured, tested and shipped as a complete unit from the manufacturers’ location within the USA.

3.2.1 Castings/Forgings: All castings/forgings shall be free from defects, scale, or mismatching. Processes such as welding, peening, plugging, or filling with solders or paste shall not be used on casting or forgings for reclaiming any parts of the machine.

3.2.2 Surfaces: All surfaces of castings, forgings, molded parts, stampings and welded parts shall be clean and free from sand, dirt, fins, sprues, flux, and other harmful or extraneous materials. External surfaces shall be smooth, and all edges shall be either rounded or beveled unless sharpness is required to perform a function.

3.2.3 Interchangeability: All replaceable parts shall be manufactured to definite standards, tolerances and clearances in order that any such parts of a particular type or model can be replaced or adjusted without modification of the equipment.

3.2.4 Maintainability: The machine shall be designed and constructed to permit effective maintenance. The machine shall be equipped with access covers (if applicable) to facilitate inspection, cleaning, and repair of parts. There must be a repair service technician located within 20 miles of the shears location.
