TRAD 260 - MUL TI MODE MULTI 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.
TRAD 260 - MUL TI MODE MULTI 1.3 - Electrical equipment according to Euro-pean 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).

SEZ. A - A 4.
TRAD 260 - MUL TI MODE MULTI 5.2 - Vice - System fro clamping the material during the cutting operation, operated with approach handwheel and locking lever or by a pneumatic device (optional). - Select the cutting speed on switch ( 2 ): position 1 = 32 m/min position 2 = 64 m/min - Strike the start/reset push-button ( 3 ). - Turn the selector ( 4 ) to the desired function mode: 3 2 5.
TRAD 260 - MUL TI MODE MULTI FIGURE C FIGURE A MANUAL MODE - Turn the selector ( 4 ) to the center ( see figure B ) to pull down the sawframe with no damping. - Start the blade by pressing the trigger switch ( 7 - figure D ) and pull down the sawframe to cut your workpiece. The motor will stop at the end of the cut as soon as you release the trigger switch.. Note: the sawframe return spring ( 8 - figure E ) must be tensioned as much as to counterbalance the weight of the sawframe.
TRAD 260 - MUL TI MODE MULTI - Once you selected the function mode ( see paragraph 6.1 ), place the piece to be cut inside the vice ( 9 ) by moving jaw to about 3 - 4 mm and lock with lever ( 10 ). - Reach for handgrip ( 7 ) of the SAW FRAME control lever, strike the push-button and check that the blade is turning in the direction indicated ( if not, invert the two phase leads); - Make sure that the cooling liquid flows regularly. 10 7 REGULATING THE MACHINE 7.
TRAD 260 - MUL TI MODE MULTI 7.5 - Cutting angle adjustment - Unlock lever (8) and rotate the saw frame arm until you reach mechanical stop and check if the index corresponds to 45°; if not operate on the set screws to make measures meet. 8 7.3 - Vice - The device does not require any particular adjustment; in case of excess play of the sliding guide, tighten slide screw more. 7.6 - Saw frame lowering control device 7.
TRAD 260 - MUL TI MODE MULTI BEFORE PERFORMING THE FOLLOWING OPERATIONS, THE ELECTRIC POWER SUPPLY AND THE POWER CABLE MUST BE COMPLETELY DISCONNECTED. 7.7 - Changing the blade To change the blade: - Lift the saw frame. - Loosen the blade with the handwheel, remove the mobile blade-guard cover, open the flywheel guards and remove the old blade from the flywheels and the blade guide blocks.
TRAD 260 - MUL TI MODE MULTI 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.

TRAD 260 - MUL TI MODE MULTI Set Saw teeth bent out of the plane of the saw body, resulting in a wide cut in the workpiece. This set is associated with very fine teeth and it is mainly used for the cutting of pipes and thin section bars (from 1 to 3 mm). ALTERNATE SET (IN GROUPS): Groups of cutting teeth right and left, alternated by a straight tooth. REGULAR OR RAKER SET: Cutting teeth right and left, alternated by a straight tooth.

TRAD 260 - MUL TI MODE MULTI 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.
TRAD 260 - MUL TI MODE MULTI 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.
TRAD 260 - MUL TI MODE MULTI FAULT PROBABLE CAUSE REMEDY Blade guide pads not regulated or dirty because of lack of maintenance Check distance between pads (see “Machine adjustments” in the Blade Guide Blocks section): extremely accurate guiding may cause cracks and breakage of the tooth. Clean carefully. Check that the tightening handwheel is against the microswitch that ensures ideal tightening.
TRAD 260 - MUL TI MODE MULTI 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.
TRAD 260 - MUL TI MODE MULTI 12.2 - Electrical components diagnosis FAULT PROBABLE CAUSE REMEDY MACHINE DOES NOT WORK Power supply Check: Fuses “FU 1” Check electrical efficiency and check for shorts that trigger such protections. Check closing of the flywheel guard. Check the efficiency of the device; replace it if damaged. Make sure to have tightened the blade with the relevant handwheel and to have actuated the microswitch. It must be turned to position 1 or 2.
