SAR440SAGDS 1 REFERENCE TO ACCIDENT - PREVENTION REGULATIONS This machine has been built to comply with the national and community accident-prevention regulations in force. Improper use and/or tampering with the safety devices will relieve the manufacturer of all responsibility. 1.1 - Advice for the operator - Check that the voltage indicated on the plate, normally fixed to the machine motor, is the same as the line voltage.
SAR440SAGDS 1.3 - Electrical equipment according to European Standard "CENELEC EN 60 204-1" which assimilates, with some integrating modifications, the publication "IEC 204-1" - The electrical equipment ensures protection against electric shock as a result of direct or indirect contact. The active parts of this equipment are housed in a box to which access is limited by screws that can only be removed with a special tool; the parts are fed with alternating current at low voltage (24 V).

SAR440SAGDS - the CUTTING SPEED and the TYPE of BLADE - combined with a suitable lowering of saw frame - are of decisive importance for cutting quality and for machine performance (for further details on this topic, see below in the chapter on “Material classification and blade selection”).
SAR440SAGDS 7.5 - 7.3 - Vice -- The rapid advancement of the vice to the object to be cut is obtained by manually moving the vice and lifting the latch ( F ). Before blocking the object to be cut with the hand wheel check that the latch is gripped to the rack. - The vice unit can be positioned to the left or right of the blade. Ensure that this positioning has been executed correctly in order to avoid irreparable damage to the saw.
SAR440SAGDS BEFORE PERFORMING THE FOLLOWING OPERATIONS, THE ELECTRIC POWER SUPPLY AND THE POWER CABLE MUST BE COMPLETELY DISCONNECTED. 7.8 – Replacing the blade - Lift the sawframe in upright position. - Loosen the blade with the hand wheel, remove the shield of the mobile blade guide and the shield of the belt cleaning brush. - Open the posterior and anterior carter flywheels and extract the old blade from the flywheels and from the blade guide blocks.
SAR440SAGDS 9 MATERIAL CLASSIFICATION AND CHOICE OF TOOL Since the aim is to obtain excellent cutting quality, the various parameters such as hardness of the material, shape and thickness, transverse cutting section of the part to be cut, selection of the type of cutting blade, cutting speed and control of saw frame lowering.

SAR440SAGDS the cutting of pipes and thin section bars (from 1 to 3 mm). Set Saw teeth bent out of the plane of the saw body, resulting in a wide cut in the workpiece. REGULAR OR RAKER SET: Cutting teeth right and left, alternated by a straight tooth. Of general use for materials with dimensions superior to 5 mm. Used for the cutting of steel, castings and hard nonferrous materials. WAVY SET: Set in smooth waves.

SAR440SAGDS 12 TROUBLESHOOTING This chapter lists the probable faults and malfunctions that could occur while the machine is being used and suggests possible remedies for solving them. The first paragraph provides diagnosis for TOOLS and CUTS, the second for ELECTRICAL COMPONENTS. 12.1 - Blade and cut diagnosis FAULT PROBABLE CAUSE REMEDY TOOTH BREAKAGE Too fast advance Decrease advance, exerting less cutting pressure. Adjust the braking device if mounted on the machine.
SAR440SAGDS FAULT PROBABLE CAUSE REMEDY PREMATURE BLADE WEAR Faulty running-in of blade See “Material classification and blade selection” in the Blade running-in section. Turn teeth in correct direction.
SAR440SAGDS FAULT PROBABLE CAUSE REMEDY Blade guide pads not regulated or dirty because of lack of maintenance Check distance between blocks (see “Machine adjustments” in the Blade Guide Blocks section): extremely accurate guiding may cause cracks and breakage of the tooth. Clean carefully.
SAR440SAGDS FAULT PROBABLE CAUSE REMEDY Broken teeth Irregular work of the blade due to the lack of teeth can cause deflection in the cut; check blade and if necessary replace it. Check level of liquid in the tank. Increase the flow of lubricating refrigerant, checking that the hole and the liquid outlet pipe are not blocked. Check the emulsion percentage.
