2.1 Short description

The CM501 block saw is designed for durability and high performance for onsite wet and dry cutting operations of a wide range of masonry, refractory and natural stone products. As with all other NORTON products, the operator will immediately appreciate the attention given to detail and quality of materials used in construction. The machine and its component parts are assembled to high standards assuring long life and minimum maintenance.

2.2 Purpose of use

The machine is designed for cutting a large range of building and refractory materials. It is not designed for cutting wood or metals.

2.3 Layout

Frame (1) The jig-welded, reinforced and all-steel construction, diagonally braced to ensure perfect rigidity. The frame includes a large capacity, sloping water tray with drain plug. Frame has built-in fork lift brackets (7) for easy transportation. The large base ensures stability while used.

Cutting head (2) Jig-welded, steel console equipped with pivot bar, which is fixed to frame uprights. Console supports the electric motor and switch (10), the belt drive with its guard (4), the blade shaft assembly and the stay level blade guard (3). The balancing of the cutting head is achieved using a heavy-duty spring. Bearings are machined for perfect fit and alignment. Blade guard (3) Jig-welded steel construction with stay level arm and 500mm-diameter blade capacity, which offers maximum operator protection and increased visibility of the work piece. Incorporated in the blade guard is a shaft vent cover, which can be easily hinged opened. This allows easy access to shaft for inspection and blade replacement when motor is switched off, while fully protecting the blade when in operation. Down feed and cutting depth adjustment The spring-loaded cutting head, activated by hand with the grip on the blade guard or with the foot pedal (5), ensures smooth lowering of the cutting head for shock-free penetration of the work piece and improved control of the cutting pressure. A crank assembly (6) in conjunction with a depth locking device on the cutting head pivoting bar enables the operator to set the cutting head to desired maximum cutting depth. Conveyor cart (8) Large, heavy-duty conveyor cart fitted with water flow-control vents, mounted on 4 rollers to give maximum stability and smooth movement. The conveyor cart is equipped with graduated scale on the backstop and with a guide-a-cut device. Water cooling system (9) The coolant system comprises:

• A powerful, submersible mechanical water pump.
• Plastic suction pipe delivering the water from the water pan to the cutting head.
• A large capacity water pan supplied with drain plug.
• A water-tap, fitted to the blade guard, permitting controlled water flow.
• Two water nozzles located inside the blade guard ensure adequate flow of water to both sides of the cutting blade.
• A water curtain, fixed to head pivoting bar restricts water spray and minimises water loss. Electrical Motor and switch (10) Motor: Low voltage trigger (NVR) built in the switch prevents the motor to restart for example after a power cut. The electric motor has an overload protection. Thermal overload tripping can occur for two reasons: a. tripping under light load If connection is incorrect b. tripping under heavy load If motor has been overloaded

3 Assembly and commissioning

The machine is delivered fully equipped and assembled (although without diamond blade) and is ready for operation after connection to the appropriate power supply.

3.1 Tool assembly

Only NORTON blades can be used with the CM501. All tools used must be selected with regard to their maximum permitted cutting speed for the machine’s maximum permitted rotation speed. Before mounting a new blade into the machine, switch 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 of rotation is correct. Wrong direction of rotation blunts the blade quickly.
• Replace outer blade flange.
• Tighten hexagonal nut with spanner supplied for this purpose.
• Shut the vent cover. The blade bore must correspond exactly to the diameter of the blade shaft. Cracked or damaged bore is dangerous for the operator and for the machine.

3.2 Electrical connections

Check that,

• the voltage/phase supply corresponds to the information 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

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-Triangle-Switch on Y. Wait until the blade reaches its maximum rotational speed, then turn the Star-Triangle-switch on Δ. 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, then reverse the motor polarity by turning the

phase inverter inside the male plug with a screwdriver. Machine dual voltage 230V/400V Set the 230V/400V switch on the voltage corresponding to the one supplied to your machine. A wrong voltage choice can damage the electrical equipment 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, then reverse the motor polarity by turning the phase inverter inside the male plug with a screwdriver.

3.4 Water cooling system

Fill the water pan with clean water to approximately 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 premature 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 from its water.

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 truck, 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 period, 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 constant temperature.

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 to 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 the 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 press 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 pushed into it as shown.

• Lower the cutting head to the desired cutting depth (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 pressure towards the rotating blade and cut the material as shown on the picture. NOTE: While recommended, it is not absolutely necessary 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 guard or pressing on the foot pedal. If the full depth of cut requires excessive pressure (on very dense material e.g.) make 2 or 3 shallow cuts.

5.2.2 Multiple step cutting

Multiple step cutting consists of moving the conveyor 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 blade.
• 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 surface of the material.
• Then pass the material beneath with rapid full length strokes, taking a shallow cut (approximately 3 mm deep as shown on the picture) on 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 the conveyor cart. NOTE: the harder the material, the more rapid should be the forward and backward strokes. Step cutting lessens the area of the blade circumference in contact with the material, keeping the blade cool, running free and cutting at peak efficiency.

5.2.3 General advice for the cutting

• Material weighting under 40 kg and having dimensions smaller than 600x500x390mm (cut with reversing of the material) can be cut with the machine.
• Before commencing work make sure tools are firmly seated!
• Select the right tools as recommended by the manufacturer depending on the material to be worked, the working procedure (dry or wet cut) to be carried out and the required efficiency.
• Apply cooling water continuously whilst cutting and in good time! Make sure the water pan contains enough water.
• When dry cutting, ensure sufficient dust extraction and wear a dusk protection mask! You can also order a dust extraction device (Art. Number 00310004580).
• 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 motor by pushing on the black button located on the motor (230V motors) or on the switch (115V motors) 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.

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 the machine isolated from the electrical supply. Cleaning of the machine Your machine will last longer if you clean it thoroughly after each day of work, especially water pump, water pan, motor and blade flange. Lubrication The CM501 uses life-lubricated bearings. Therefore, you don’t 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 pivot 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 machine. Always use a matched set of belts. Do not replace single belts.
