• The exposure time to vibration is based on the performance of work (related to the adequacy Machine / Tool / worked material / operator)

When evaluating risks due to hand-arm vibration, you need to take into account effective usage at rated power of machine during a full day of work; quite often you will realise that effective utilisation time represents around 50% of overall duration of work. You have to consider, of course, breaks, water feeding, preparation of work, time to move the machine, disk mounting…

ASSEMBLY AND COMMISSIONING

The machine is delivered fully equipped (although without diamond blade). It is ready for operation when you mount the diamond blade, the handles and the conveyor cart and after you connect to the appropriate power supply.

Tool assembly
Only NORTON blades with a maximum diameter of 350 mm can be used with the CM 35.
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:

• Loosen the screw in front of the blade guard and disconnect the water hose on its the left side and open it.
• Loosen the hexagonal nut on the blade shaft (attention: left threaded), which holds the removable outer flange, with the supplied wrench.
• Remove the outer flange.
• Clean the flanges and blade shaft and inspect for wear.
• Mount the blade on arbour ensuring that direction of rotation is correct. Wrong direction of rotation blunts the blade quickly.
• Replace outer blade flange.
• Tighten the hexagonal (attention: left threaded), nut with the supplied wrench.
• Close the blade guard, retighten the screw on the front of the blade guard and reconnect the water hose.

ATTENTION: 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.

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. 5mm2-section per phase.

Starting the machine

1. Place the machine on a flat well illuminated location. Use the adjustable legs to ensure the stability while using the machine.
2. Mount the handle and secure it with the bolt.
3. Mount the blade as previously described.
4. Release the rolling cart from the brake.
5. Set the right cutting depth with the rotation lock handle.
6. Plug the machine in the power supply socket and check that the blade runs in the right direction.
7. Connect the flexible hose of the vacuum cleaner to the waste socket of the machine and to the power supply.
8. Connect the machine to the water supply if a wet cutting is needed.
9. Start cutting.

TRANSPORT AND STORING

1. Securing for transport
   Before transporting the machine, always remove the blade. Lock the conveyor thanks to the latch.

2. Transportation procedure
   The machine could be transported alone with a two-wheel hand truck or manually with the help of a second person.
   The machine does not have lifting hooks.

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
   • Empty the water system
     The storage site must be clean, dry and at a constant temperature.

OPERATING THE MACHINE

You will find in this chapter some advice about where and how to put up the machine.

Jobsite
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 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.

Area dedicated for the use and maintenance of the machine
You should have 2 m in front of the machine and 1,5 m on both sides to get a comfortable use of the machine.

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. Always keep your hands away from the moving blade. 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.

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
• Fix position by tightening the clamping device
• Put material on conveyor cart
• Start the machine
• 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 when jam cutting. The desired cutting depth can be maintained by holding firmly the depth feed handle on the blade guard. 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.
• Start the machine.
• 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.
• 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.

General advice for the cutting

• Material weight under 10 kg and having dimensions smaller than 280×340 can be cut with the machine.
• Before commencing work make sure the diamond blade is 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.
• In case the thermal protection trips, wait until the motor has cooled down before starting the machine again.
• For security reason, every damaged tools or parts must be replaced.

MAINTENANCE AND SERVICING

To ensure a long-term quality from the cutting with the CM 35, please follow the maintenance plan below :

Maintenance of the machine
Always perform the maintenance of the machine with the machine isolated from the electrical supply.

Lubrication
The CM 35 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, motor and blade flange.

FAULTS : CAUSES AND CURES

Fault-finding procedures
Should any fault occur during the use of the machine, turn it off, and isolate it from the electrical supply. Any works dealing with the electrical system or supply of the machine can only be carried out by a qualified electrician.
