13 3 assembly and commissioning the machine is delivered fully equipped and assembl ed (although without diamond blade) and is ready for operation after connection to the appropr iate power supply. 3.1 tool assembly only norton blades can be used with the CM501. all tools used must be selected with regard to thei r maximum permitted cutting speed for the machines maximum permitted rotation speed. before mounting a new blade into the machine, switc h off the machine and isolate it from the main source of electricity. to mount a new blade, follow these steps: open the shaft vent cover on the blade guard. loosen the hexagonal nut on the blade shaft, which holds the removable outer flange. remove the outer flange. clean the flanges and blade shaft and inspect for wear. mount the blade on arbor ensuring that direction o f rotation is correct. wrong direction of rotation blunts the blade quickly. replace outer blade flange. tighten hexagonal nut with spanner supplied for th is purpose. shut the vent cover. the blade bore must correspond exactly to the diame ter of the blade shaft. cracked or damaged bore is dangerous for the operator and for the mach ine. 3.2 electrical connections check that, the voltage/phase supply corresponds to the inform ation indicated on the motor plate. available power supply must have ground connection in conformity with safety regulations. the connecting cables should have at least a 2.5mm 2 -section per phase. 3.3 starting the machine 230v motor open the switch cover and press the green button to start the machine. to stop either use the red button or press directly on the switch front cover. 115v motor to switch the machine on, turn the 0/1 switch on 1. to switch the machine off, turn the 0/1 switch on 0. 400v motor put the on-off-switch on on. then put the star-tria ngle-switch on y. wait until the blade reaches its maximum rotational speed, then turn the star-triangle-switch on d . the direction of rotation is indicated on the blade guard. if the direction of rotation does not correspond to the direction shown by the arrow, the n reverse the motor polarity by turning the
14 phase inverter inside the male plug with a screwdri ver. machine dual voltage 230v/400v set the 230v/400v switch on the voltage correspondi ng to the one supplied to your machine. a wrong voltage choice can damage the electrical equi pment of your machine. the direction of rotation is indicated on the blade guard. if the direction of rotation does not correspond to the direction shown by the arrow, the n reverse the motor polarity by turning the phase inverter inside the male plug with a screwdri ver. 3.4 water cooling system fill the water pan with clean water to approximatel y 2cm from top (ensure that bottom of pump is fully immersed in water). open water-tap at blade guard (note that handle on water-tap should be in line with water-flow). ensure that water is flowing freely in the circuit and is delivered adequately to both sides of the blade, as insufficient water supply may result in p remature failure of the diamond blade. the water pump must never run without water. always make sure that there is enough water in the pan and refill if necessary. in case of frost, empty the water cooling system fr om its water.
15 4 transport and storing 4.1 securing for transport before transporting or lifting the machine, always remove the blade and the conveyor cart and empty the water pan. 4.2 transport procedure if you transport the machine using a fork-lift truc k, you have to use exclusively the two fork lift brackets under the water pan. 4.3 long period of inactivity if the machine is not going to be used for a long p eriod, please take the following measures: completely clean the machine loosen the drive belts empty the water system take the water pump out of the slurry and clean it thoroughly. the storage site must be clean, dry and at a consta nt temperature.
16 5 operating the machine 5.1 site of work 5.1.1 siting the machine remove from the site anything, which might hinder the working procedure! make sure the site is sufficiently well lit! observe manufacturer's conditions for connecting t o power supplies! place electric cables in such a way that damage by the device is excluded! make sure you have a continual adequate view of th e working area so you can intervene in the working process at any time! keep other staff out of the area, so you can work securely. 5.1.2 space required for operation and maintenance leave 2 m in front of the machine and 1,5 m around it for usage and maintenance of the CM501. 5.2 cutting methods to use the machine correctly, you must face it with one hand on the handle of the cutting head, and the other on the conveyor cart. you can possibly pr ess on the pedal with one foot. always keep your hands away from the moving blade. 5.2.1 full depth or fixed cutting in full depth or fixed cutting, the cutting head is locked in a fixed position and the material is pus hed into it as shown. lower the cutting head to the desired cutting dept h (in through cutting, lower cutting head until blade periphery reaches max. 3mm under the surface of the conveyor cart) by means of the handle on the blade guard or of the foot pedal, or using the crank. put material on conveyor cart against the backstop . push the conveyor cart slowly and without undue pr essure towards the rotating blade and cut the material as shown on the picture. note: while recommended, it is not absolutely neces sary to lock the cutting head into a given depth position with the crank when jam cutting. the desired cutting depth can be maintained by holding firmly the depth feed handle on the blade g uard or pressing on the foot pedal. if the full depth of cut requires excessive pressure (on very d ense material e.g.) make 2 or 3 shallow cuts.
17 5.2.2 multiple step cutting multiple step cutting consists of moving the convey or cart with the material to be cut back and forward under the rotating blade, place the material to be cut on the conveyor cart firmly against the guide-a-cut and the backstop, keeping the hands well away from the blad e. move conveyor cart forward near the blade and pull down the cutting head until blade is lowered to a point where it will lightly contact the surfac e of the material. then pass the material beneath with rapid full len gth strokes, taking a shallow cut (approximately 3 mm deep as shown on the picture) o n the forward. on the backward stroke, lift the blade just clear over the cutting line. complete each rapid stroke backward and forward by passing the material beyond the centre of the blade before starting the reverse movement of t he conveyor cart. note: the harder the material, the more rapid shoul d be the forward and backward strokes. step cutting lessens the area of the blade circumfe rence in contact with the material, keeping the blade cool, running free and cutting at peak effici ency. 5.2.3 general advice for the cutting material weighting under 40 kg and having dimensio ns smaller than 600x500x390mm (cut with reversing of the material) can be cut with the mach ine. before commencing work make sure tools are firmly seated! select the right tools as recommended by the manuf acturer depending on the material to be worked, the working procedure (dry or wet cut) to b e carried out and the required efficiency. apply cooling water continuously whilst cutting an d in good time! make sure the water pan contains enough water. when dry cutting, ensure sufficient dust extractio n and wear a dusk protection mask! you can also order a dust extraction device (art. number 00 310004580). when cutting work is finished, close the water-tap so you can remove the cut pieces from the conveyor cart without getting wet. if the thermal protection trips, reactivate the mo tor by pushing on the black button located on the motor (230v motors) or on the switch (115v moto rs) or allow the thermal protection to cool down (400v and dual tension 230v/400v motors). wait a few minutes to allow the motor to cool down before restarting the machine.
18 6 maintenance and servicing to ensure a long-term quality from the cutting with the CM501, please follow the maintenance plan below: begin of the day during the changing of tool end of the day or more often if required every week after a fault after a damage visual control (general aspect, watertightness) whole machine clean flange and blade fixing devices clean belts tension check and adjust motor cooling fans clean water pump clean water pan clean water hoses and nozzles clean water pump filter clean cart guiding bars clean motor housing clean reachable nuts and screws tighten up maintenance of the motor always perform the maintenance of the motor with th e machine isolated from the electrical supply. cleaning of the machine your machine will last longer if you clean it thoro ughly after each day of work, especially water pump, water pan, motor and blade flange. lubrication the CM501 uses life-lubricated bearings. therefore, you dont need to lubricate the machine at all. adjustment and replacement of the belts to adjust the belts, firstly remove the belt guard by unscrewing the 4 screws. to remove the belt guard, you need to remove the upper part of the piv ot bearing. loose the 4 motor bolts and shift the motor by using the two screws on the side. to replace the belts, move the motor forward on the cutting head. adjust the belts and retighten them by shifting the motor to the rear of the machi ne. always use a matched set of belts. do not replace s ingle belts.
19 7 faults: causes and cures 7.1 fault-finding procedures should any fault occur during the use of the machin e, turn it off, and isolate it from the electrical supply. any works dealing with the electrical syste m or supply of the machine can only be carried out by a qualified electrician. 7.2 trouble-shooting guide trouble possible source resolution no electricity check the electrical supply (fuse for example) connection cable section too small change connection cable defective connection cable change connection cable defective switch caution : can only be solved by qualified electrician motor is not running defective motor change motor or contact motor manufacturer blade is not turning belts not tightened or defecti ve check the belts tension and change them if needed cutting advance too quick cut slowly blade is blunt or glazed sharpen the blade in calcareous stone defective blade change blade motor stops during the cutting, but can be restarted after a short period (overload protection) wrong blade specification for the application change blade not enough water in the pan refill the water pan water tap is closed open tap on blade guard water supply system is blocked up clean water supply system no water on the blade water pump is not working check if pump pulley is driven by the belts change the pump
