Electrical Connections

The electrical equipment has an IP54 protection degree and an under-voltage coil to prevent the machine from starting up unexpectedly after a power cut. Before connecting:

• Check that the voltage/phase supply corresponds to the information indicated on the motor plate.

• The available power supply must have a ground connection in conformity with safety regulations.

• The connecting cables should have at least a 2.5mm²-section per phase.

Switch on the machine (230V Motor)

To start the machine, press the green button. To switch it off, press the red button.

Direction of rotation

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.

Emergency Stop

The ON-OFF switch also serves as an emergency stop. To stop the machine, press the red button. To restart the machine after an emergency stop, press the green button.

The NORTON CLIPPER CM70 ALU is designed to work with water-cooled diamond blades. Follow these steps for the water cooling system:

• Put enough water in the tank (up to about 2.5 cm from the top edge), making sure the pump body is fully submerged.

• The blade should be sufficiently watered on both sides. You can adjust the amount of water using the tap in the blade housing.

• If the blade is not sufficiently watered, the segments may heat up, which accelerates damage and increases the risk of blade rupture. This is why the pipes and nozzles must not be clogged.

• In no case should the water pump run empty. Therefore, ensure that the water level in the tank never falls below the water suction of the pump.

• If there is a risk of frost, please empty the blade cooling system completely.

• During cutting operations, many impurities accumulate in the bottom of the tank. It is then necessary to frequently change the water in order to guarantee the proper functioning of the pump and optimal cooling of the blade. The tank is equipped with a drain plug which facilitates this task.

Securing for transport

Before transporting or lifting the machine, always remove the blade and empty the water pan. The conveyor cart must be secured:

• move the conveyor cart to the end of the machine.

• fix it using the pin on the rear post of the chassis and the eye screw on the conveyor cart.

Transport procedure

The machine can be moved on a flat surface using its wheels. Only use the lift brackets to lift the machine, as other parts of the machine are not designed for this purpose. The machine is not intended to be transported by crane.

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.

• 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.

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.

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 CM70 ALU.

To use the machine correctly, you must face it with one hand on the handle of the cutting head, and the other on the handle of the conveyor cart. Always keep your hands away from the moving blade.

Jam or fixed cutting

In jam or fixed cutting, the cutting head is locked in a fixed position and the material is pushed into it.

• Lower the cutting head to the desired cutting depth (in “through cutting”, lower cutting head until blade periphery reaches max. 3-5mm under the surface of the conveyor cart) by means of the handle on the blade guard.

• Fix position by tightening the clamping device.

• Put material on conveyor cart.

• Push the conveyor cart slowly and without undue pressure towards the rotating blade and cut the material.

NOTE: If the full depth of cut requires excessive pressure (on very dense material e.g.) make 2 or 3 shallow cuts.

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) 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.

• Material weighing under 30 kg and having dimensions smaller than 600x500x265mm can be cut with the CM70 ALU.

• 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 (wet cut) to be carried out and the required efficiency.

• Apply cooling water continuously whilst cutting and in good time.

• 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, wait a few minutes to allow the motor to cool down before restarting the machine.

• In case of the triggering of the thermal protection, press the black button on the switch (230V motor).

To ensure long-term quality, follow the maintenance plan below. Always perform maintenance with the machine isolated from the electrical supply.

Lubrication

The NORTON CLIPPER CM70 ALU uses life-lubricated bearings. Therefore, you don’t need to lubricate the machine at all.

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.

The conveyor cart has an anti-tipping system so that it does not derail. If you want to remove the cart for any maintenance operation, you should loosen the red bolt on the anti-tipping system. Then you must slide the anti-tipping system to extract the cart from the slides.
