2 Machine description

Any modification, which could lead to a change in the original characteristics of the machine, may
be done only by Saint-Gobain Abrasives who shall confirm that the machine is still in conformity with
the safety regulations.

2.1 Short description

The CST 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 like tiles, stair
step or window sill. It is not designed for cutting wood or metals.

2.3 Layout

Foot and handles (1)

The jig-welded, reinforced and all-steel construction feet ensures perfect stability. Precision springs
allow the feet to be folded up. Handles can be used for the transport of the machine when the feet
are folded up, and for locking the feet when the machine is standing on its feet.

8

Frame (2)

Built in aluminium profile, the frame is light and resistant. The welded-steel side of the machine
ensure that the axles are parallel to the table. The axle assembly can also be tilted until 45º to make
bevel cuts. The head axles (3) made of aluminium, guide the cutting head over the table. The head
consoles (4) ensure the parallelism of the two axles, and rigidity of the assembly.

Blade guard (5)

Jig-welded steel construction with 350mm-diameter blade capacity, which offers maximum operator
protection and increased visibility of the work piece.
Incorporated in the blade guard is an outer metal 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.

Cutting head (6)

Jig-welded steel console. Console supports the electric motor and the blade guard. The movement
of the cutting head on the axles involves nylon wheels. The balancing of the cutting head is
achieved using a heavy-duty spring. A depth-locking device (7) fixed over the cutting head enables
the operator to set the cutting head to desired or to maximum cutting depth.

Down feed and cutting depth adjustment

The spring-loaded cutting head, activated by hand with the grip over the blade guard ensures
smooth lowering of the cutting head for shock-free penetration of the work piece and improved
control of the cutting pressure.

Cutting table (8)

Large, heavy-duty table fitted with water flow-control vents. The table is equipped with backstops
and a guide-a-cut device (9).

Water cooling system (10)

The coolant system comprises:

• A powerful, submersible electrical water pump.

• Plastic suction pipe delivering the water from the water pan to the cutting head.

• A large capacity aluminium water pan supplied with drain plug.

• A water-tap, fitted to the blade guard, permitting controlled water flow.

• Two water nozzles located on both side of the blade guard ensure adequate flow of water to

both sides of the cutting blade.

Electrical Motor (11) and switch (12)

Leroy-Somer motor with 2,2kW. 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 (although without diamond blade) and is ready for operation
after assembly of the blade and the handles, and connection to the appropriate power supply.

3.1 Tool assembly

Only NORTON blades with a maximum diameter of 350 mm can be used with the CST.
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 outside cover of blade guard by loosening the two knobs on the side of the guard.

• Loosen the hexagonal nut (Caution: left-threaded) 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 retractable blade guard cover and tighten the two knobs.

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 Handle assembly

To prevent the handles to be damaged during transportation, they are disassembled from the
machine. You can reassemble them by using the M10x25 screws supplied with the machine.

3.3 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.

3.4 Starting the machine

230V or 115V 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.

400V Motor

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.

12

3.5 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). Use the pump switch so you can use the pump.
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.

13

4 Transport and storing

4.1 Securing for transport

Before transporting or lifting the machine, always remove the blade and empty the water pan. Also
lock the cutting head on the axles. To do so, move the head so, that the screw (1) is facing the hole
(2). Then tighten the screw until it enters the hole and prevent the cutting head from moving.

4.2 Transport procedure

The machine can be moved on a flat surface using its wheels. You must first fold away the feet. Two
operators are required for this. Lift the rear handle and push lightly on the rear foot of the machine
with your foot. The foot of the machine will automatically fold away. You can then put the rear of the
machine on the floor. Then proceed the same way with the front foot.

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

• 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.

14

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 around the machine for usage and maintenance of the CST.

5.2 Cutting material

To use the machine correctly, you must face it with one hand on the handle of the cutting head, and
the other ready to shut the machine down in case of emergency. Always keep your hands away
from the moving blade.

• 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 over the cutting head

• Fix position by tightening the clamping device over the blade guard

• Put material on the table

• Push the cutting head slowly and without undue pressure towards the material and cut the

material as shown on the picture.

• You can also cut thicker material by reversing the material on the table.

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.

15

5.3 General advice for the cutting

• Material weighting under 30 kg and having dimensions smaller than 650x660x220mm for the

CST65, 850x660x220mm for the CST85, 1000x660x220mm for the CST100 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!

• When cutting work is finished, switch the water pump off so you can remove the cut pieces from

the conveyor cart without getting wet.
If the thermal protection trips, allow the thermal protection to cool down. Wait a few minutes to allow
the motor to cool down before restarting the machine.
