The enclosed CE Declaration of conformity, togheter with the CE mark on product, essentially comprise and are an integral part of the machine : both guarantee product conformity with the aforesaid safety Directives. 1.3 RECOMMENDED AND NOT RECOMMENDED USAGE This belt sawing machine was designed and constructed according to the most advanced technologies and may be used for all cutting requirements for metals commonly used in industry and artisanship. 1 INTRODUCTION TO USE Before starting work with your sawing machine, carefully read this instructions manual so that you are familiar with the machine and its uses and where it should not be used. Keep this manual in a safe place. It is an integral part of the machine and should be used for reference in operating the machine correctly and in the proper safety conditions. Use the machine only and exclusively for the uses specified below, as recommended in this manual. The machine should not in any way be tampered with, or forced, or used for unsuitable purposes. It - can cut: COMMON STEELS (FE 37...) SPECIAL STEELS (C 40, 18NiCrMo5...) ALUMINIUM AND ITS ALLOYS BRASS BRONZE STEEL TUBING (FE 35, FE 52...) PROFILED SECTIONS IN SHEET METAL AND ALUMINIUM It is not suitable for cutting: - WOOD AND SIMILAR MATERIALS - BONE AND SIMILAR MATERIALS ATTENTION: The band saw has been developed and manufactured to cut in dry condition; the use of any cooler by lubricating oil makes the machine unusable. Consult the relative sections for cutting capacities, the speeds to use and the type of tools for use according to the material to be cut and its section. (See list of contents). 7 EN 5 ACCESSORIES ...................................................... 11 Never underestimate the warnings “ATTENTION CAUTION” given in this manual. In order to draw the user’s attention and to preserve safety, hazardous operation are preceded by symbols and notes that point out the danger and explain how to behave to avoid any risk. These symbols and notes are divided in three categories, identified by the following words: EN 1.4 STANDARD SAFETY PROCEDURS 1.8 DESCRIPTION OF THE MACHINE (Fig. 1) - Do not use the machine in very damp places or in the presence of inflammable liquids or gases. - Do not use it in the open air when general weather and environmental conditions are unfavourable (eg. explosive atmospheres, during a storm or rain). - Wear suitable clothes, without wide sleeves or articles such as scarves, chains and bracelets which could get caught in the moving parts. - Always use personal protection devices: protective goggles as recommended by safety standards, gloves of the right size, headphones or earplugs, and hairnets if necessary. - Use the tools recommended in this manual if you want to achieve the best performance from your sawing machine. - Any power cable extensions must be type approved and comply with safety standards. - Avoid using the machine if your psycho-physical condition are precarious or upset. The belt sawing machine consists of two basic parts: the machine body 5 complete with motor and drive 7 which is integrated into lower part, consisting of the clamp 11, the base 13 and swivel support 9. Here is a list of the main parts with the number indicating it in the drawing. Legend Fig. 1 1 Command grip 2 Blade tension handwheel 4 Sliding blade guide 5 Machine body 6 Blade 7 Motor 8 Control box 9 Bar stop 10 Clamp (vice) 11 Morsa 12 Clamp drive 13 Base 1.5 WEIGHT = 18 Kg. SIZE = cm 85 x 83 x H60 in maximum overall dimensions. PACKAGING SIZE = cm 390 x 870 x H520 SAFETY PROCEDURS FOR FURTHER RISK - Always keep processing residues away from the cutting area. - Always use the clamp. The parts to be cut must always be held firmly in the clamp. - Always keep hands away from the working areas while the machine is moving: before loading or unloading the part, release the run button on the hand grip. - Do not force the machine unnecessarily : excessive cutting pressure could cause rapid wear to the blade and negatively influence the performance of the machine in terms of finishes and cutting precision. 1.6 NOISE CONDITIONS In normal conditions of use as described in this manual, this belt sawing machine determines an equivalent level of acoustic pressure: Leq = 82 dB(A) when operating unloaded; Leq = 84,3 dB(A) during processing (eg. cutting of a steel tube Ø 80 mm thickness 5 mm), at cutting speed of 80 m/min., with a weighted operating cycle of 1 minute. The frequency root mean RMS weighed for hand-arm acceleration does not exceed 2.5m/s². Measurement were obteined in compliance with UNI 7712, ISO 3740, ISO 3746 and CEE 89/392 regulation. NOTE: Personal hearing protection should be used, such as headphones or earplugs. 1.7 INFORMATION ABOUT THE ELECTROMAGNETIC COMPATIBILITY The European regulations on safety and, in particular, the EEC Directive 89/336 contemplate that all the equipment be equipped with shielding devices against radio interferences both from and towards the outside. This machine is equipped with filters through which the machine is safe and in compliance with above regulations. Tests were carried out according to EN 55011, EN 55014, EN 50082-1, IEC 1000-4-2, IEC 1000-4-4 regulations. 8 2 INSTALLATION 2.1 REMOVING THE PACKING Remove the wooden frame which protects the machine during transit. Try not to damage the frame as you may have to move the machine long distances or store it for long periods. 2.2 HANDLING (Fig. 2) As the machine is not heavy (Kg. 18), it can be lifted and moved by a single person by gripping it from the machine body 5, duly clamped (see pint 2.3). 2.3 TRANSPORT (Fig.2) It is necessary to low the saw body till the lower position and fix it to the base : it is sufficient to insert the pin U in the hole in the body, then lift the machine, gripping it as showed in Fig.2. For transport the machine, it is better to place it in the box it was when purchased. Ensure it is placed in the correct position indicated by the arrows on the packaging. Pay careful attention to the ideogram printed on the box as they provide all necessary information for palletization and stacking of boxes. Tying the load down with ropes or safety belts is raccomended during transportation to prevent the load from sliding or falling. 2.4 POSITION/WORK STATION (Fig.3) ATTENTION: Make sure that the machine is placed in a working area with suitable environmental conditions and lighting. The general conditions of the working environment are of fundamental importance for accident prevention. 2.5 ELECTRICAL CONNECTIONS Check that the mains to which the machine is connected is earthed in accordance with current safety regulations and that the power point is in good condition. Remember that there should be a magnetothermic protective device fitted upstream of the mains to protect all the conductors from short circuits and overloads. This protective device should be selected according to the electrical features of the machine listed below: Nominal voltage ............................................... 230 Volt ~ Nominal frequency ........................................ 50/60 Hertz Max programmed absorbed value ..................... 5 Ampere Nominal input power ......................................... 1200 Watt Power factor ............................................................... 0,96 Nominal speed ...................................... 8.000-16.000 rpm Insulation ............................................................ Classe B Type of service ............................... intermittent S4-60 % In case of power failure in mains, while you wait for power to be restored there is no danger hazard may arise: in fact, the electronic governor O is also equipped with a reset function which prevents the machine from restarting automatically. The motor of your sawing machine is equipped with a protective heat circuit breaker which interrupts the power supply when the temperature of the coils rises too high. When the power supply is interrupted, wait for normal reset. 3 ADJUSTING (Fig. 4-5-6-7-8) 3.1 TENSION OF THE BLADE (Fig.4) ATTENTION: The machine is fitted with a bladetightening device that limits tension automatically. Turn handwheel B clockwise until the clutch engages 3.2 BAR STOP (Fig.5) Use the bar stop supplied if you have to do several cuts on pieces of the same length. In this way you do not have to repeat the same measurement each time. Screw rod E into the hole of the base and fasten it with nut F. Slacken the handwheel G and place the stop L at the correct distance from the blade. Tighten handwheel G again. 3.3 CUTTING ANGLE (Fig.6) The band saw can cut at an angle varying from 0 to 60 degrees: it is sufficient to slacken the handle I and turn the swiwel support J towards the respective limit stops H and K. It is also possible to have a reference for the 45° quicksetting by turning the knob S upwards.” For all intermediate angles, turn the swiwel support J until the mark M on the support matches the corresponding position on the plate. Then lock the rotating support J again. 3.4 CUTTING SPEED (Fig.7) Your sawing machine is equipped with CESC (Constant Electronic Speed Control), which allows gradual and continuous variation of the cutting speed, adapting it to the type and dimension of the material to be cut (see CUTTING TABLE ). To select the most suitable speed, use the speed control knob O to increase or decrease the speed as you require. Example: Stainless Steel : 35 m/min. position 1 Common Steel : 40÷60 m/min. position 2-3 Allum.Alloy : 80 m/min. position 4 Pipes/sections : 70÷80 m/min. position 3-4 3.5 SLIDING BLADE GUIDE (Fig. 8) The sliding blades guide P with integrated protection fitted on your sawing machine is used to perform the cut while guiding the necessary part of the blade and fully protecting the part not used in the cutting process. Slacken the knobs Q and slide the blades guide P so as to move it closer to or further from the part to be cut, as shown in the figure. ATTENTION: If this adjustment is not done, the part of the blade not used in the cutting process will be exposed and this will create an extra risk of contact, besides altering the quality of the cut. 9 EN Place the machine on a sufficiently flat workbench so that the machine has the better possible stability. In respect of ergonomic criteria during cutting operations, the workbench must be positioned at such a height that the clamp level is between 90 and 95 cm from the ground (see fig. 3). EN 3.6 BEARINGS BLADE GUIDE (Fig.9) The blade-guide on the outside of the sawing machine are eccentric and adjustable so as to simplify blade replacement and to keep it guided as its best. They must always touch the blade slightly, so that they rotate when the blade passes, but must not be completly locked. In order to approach or remove the eccentric blade-guide, gently turn the head of the screws R using a 10 mm. wrenches key. 4 4.1 USE RUNNING IN THE BLADE ATTENTION: If the correct running in procedure is not performed, the bladès cutting precision may be irreparably compromised. To obtain the best performance, the bi-metal blades fitted on your sawing machine must be run in for a short period. For this reason the first two or three cuts should be done where possible on a solid piece Ø 40-50 mm, using a very slight pressure on the blade, and gradually increasing pressure in subsequent cuts. To gauge the correct pressure in normal operating conditions defined by this manual (see cutting table), consider for example that the first cut on solid steel (eg. C40) Ø 50 mm should be done in about 4 minutes. After running-in, the same piece may easily be cut in about 2 minutes. If the running-in process is done correctly, the finish and precision of the cut will be of better quality and the blade will last longer. 4.2 WORKING (Fig. 7) Turn the main switch D to position 1 : in doing the switch comes on and the machine is ready for operation. ATTENTION: Before starting any cutting operation, check that all the protections are complete and in the correct position. Once you have completed all the procedures and operations described so far, you may start the working processes. To perform the cut, move to the front of the machine and grip the handgrip with your right hand. ATTENTION: Keep your left hand away from the cutting area and on no account try to reach it when cutting is in process. Use your right-hand thumb to press the side release button B (Fig. 7): as such you will disable the safety system that prevents any unintentional starts. Then use your righthand forefinger to press start button A and lower the body gradually until the blade lightly touches the work piece to be cut. 10 Now begin to apply gradual pressure on the part and complete the cut. ATTENTION: Always release button A between one cutting operation and another, while you are positioning the part. do not try to block it or alter its functional characteristics in any way. If the machine suddenly stops after numerous consecutive cuts, do not be alarmed. The heat protector device of the motor has been activated, breaking the power supply when the temperature of the coils reaches the threshold limit defined by the insulation class, to prevent damage to the motor. In this case, release the button A and wait for automatic reset which usually takes place after a few minutes. Your sawing machine is equipped with an electronic speed governor which also includes a motor protection function obtained by means of an amperometric limiter. In this way it can not absorb an amount of current greater than the set one, expressed by the maximum value of absorption (see 2.5). If the limiter trips while the machine is in operation, slightly decrease the cutting pressure in addition, this enables to safeguard the blade life and performance and to obtain always a sharp and clean cut. 4.3 REPLACING THE BLADE (Fig. 9) CAUTION: When you perform this operation, always wear protective gloves to avoid contact with the teeth of the blade. - check that the main switch D (Fig. 7) is at position 0; - slacken the handles Q and slide the blades guide P as far as it will go, following the direction on the arrow (Fig. 8); - remove the protective casing unscrewing the four screws; - slacken the blade tension, turning the handwheel B in a anti-clockwise direction; - extract the blade first from the guides and then from the rubber coated pulleys; - insert the new blade first between the guides and then onto the rubber coated pulleys, with the teeth facing as showed in (Fig. 9); - put the blade under tension again as described in point 3.1. - replace the protective casing; - reposition the blade guides P in the correct position for the next cut. ATTENTION: This machine has been developed for working with the blade rotating clockwise (Fig. 9). It is absolutely necessary to check that the blade is produced according to this rotation mode. 4.4 CUTTING CAPACITY (Fig.10) 4.6 CUTTING TABLE 5 ACCESSORIES 5.1 CHOISE OF BLADE SECTION ANGLE EN The table below specifies the cutting capacity at 0, 45 and 60 degrees which may be obtained in normal conditions of use described in this manual and without placing any other object between the jaws of the clamp. CUTTING 102 0 gradi 100 x 100 90 x 120 80 45 gradi 80 x 80 80 x 82 50 60 gradi 43 x 43 43 x 50 4.5 CORRECT POSITIONING OF THE PIECE IN THE CLAMP (Fig. 11) The pieces to be cut should be fitted directly between the jaws without adding other objects. ATTENTION: Never hold the pieces to be cut in your hand. When the pieces to be cut are profiled sections, flat pieces or special shapes, refer to the examples shown in the figures. If the thickness of the profiled section is to be very thin, an outline should be fitted which copies the profile inside the profiled section itself to stop it being crushed between the jaws. Your sawing machine is equipped with a bi-metal blade measuring 1440x13x0.65 mm with variable toothing 8/12 teeth per inch, for use in the majority of cuts possible with this machine. For special requirements (see cutting table point 4.6), for example, for cutting large solid sections or profiled sections or corner pieces of small thickness, there are also blades avail-able with 6, 14 or 18 teeth per inch.

Before performing any maintenance operation, disconnect the machine electric plug from the wall outlet. 2. During maintenance operations, always wear personal protection (safety goggles and gloves). 3. Remove the processing residues from the cutting area and the blade guides whenever necessary. You are advised to use a suction device or a brush. ATTENTION: Do not use jets of compressed air. 4. If you do not intend to use the sawing machine for a long time, clean it and put it in a dry place if possible. In these cases it is advisable to slacken off the blade so that it is not kept tight for no reason. 11 EN 6.2 6.3 ASSISTENCE Should it be necessary to call qualified personnel for operations of extraordinary maintenance, or in the case of repairs, under guarantee or at a later date, you should always contact an authorized service centre or the factory directly, if there is no service centre in your area. 7 DISPOSAL OF THE MACHINE, PACKING At the end of the machine life, if the machine must be scraped, contact an authorised waste disposal centre in order to comply with the Standards for hygiene and environment safeguard. The packing must be disposed of according to the ruling standards by 2002/96/EC delivering it to authorised people for the collection, disposal or reclaim.
