1.3 Safety instructions for particular operating phases
Before commencing work
•Before commencing work, make yourself familiar with the working environment at the place of
use. The working environment includes: obstacles in the area of work and manoeuvre, the
firmness of the floor, necessary protection at the site relating to public thoroughfares and the
availability of help in the event of accidents.
•Site the machine on an even, firm and stable base!
•Check for correct mounting of the blade regularly.
•Immediately remove damaged or badly worn blades, as they endanger the operator whilst
rotating.
•The material to be cut must be held securely in place on the conveyor cart to allow no
movement during cutting operation.
•Always cut with the blade guard in position.
•Only fit NORTON diamond blades to the machine! The use of other tools can damage the
machine!
•Read the blades’ specifications carefully to choose the correct tool for your application.
•Attention is drawn to the use of BS2092 safety goggles in conformity with specified Processes
No.8 of the Protection of Eyes Regulation 1974, Regulation 2(2) Part 1.
Electrical powered machine
•Always turn off the machine and separate it from the main source of electricity before any work
on the machine is done.
•You can lock the ON-OFF-switch using a padlock.
•Make all electrical connections securely to eliminate contact of live wires with spray water or
dampness
•When the machine is used with water, it is IMPERATIVE that you earth the machine properly.
•In the event of the machine breaking down or stopping for no apparent reason, switch off the
main electricity supply. Only a qualified electrician is allowed to investigate the trouble and
remedy the fault.

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 ISM 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)
Jig-welded, reinforced and all-steel construction ensures perfect rigidity. The frame includes a large
capacity water tray (3) with drain plug. Frame has four built-in lift brackets (2) for easy
transportation.
Cutting head (4)
Jig-welded steel console equipped with pivot bar fixed to frame upright and housed in heavy-duty
bearings. Console supports the electric motor (11), the belt drive with its guard (6) and the blade
shaft assembly with the blade guard (5). Precision-machined blade shaft, held in ballbearings and is
driven by four heavy-duty V-section drive belts. The blade shaft assembly is completely enclosed in
a cutting head console, accessible for inspection by way of a removable plate. The removable blade
flange is tightened by means of a hexagonal nut.
Blade guard (5)

9
Jig-welded steel construction with 500mm-diameter blade capacity, which offers maximum operator
protection and increased visibility of the work piece.
Incorporated in the blade guard is an outer metal vent, which permits 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 (7) on the blade guard or with the
foot pedal (8), 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 (10) 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. The knob (9)
enables to lock the cutting head at the right cutting depth.
Electrical Motor and switch (11)
Motor with 5,5kW. Low voltage trigger (NVR) prevents the motor to restart for example after a power
cut.
The electric motor has overload protection. Thermal overload tripping can occur for two reasons:
a. tripping under light load
If connection is incorrect
If a phase is not under load
Check the connections and the phase voltage before restarting the machine.
b. tripping under heavy load
If motor has been overloaded
The ON-OFF switch also serves as emergency stop.

3 Assembly and commissioning
The machine is delivered fully equipped (although without diamond blade) but with the cutting head
in the water tray to avoid damage during the transportation. Before using the machine for the first
time, please follow these instructions to assemble your machine.
3.1 Cutting head assembly
The head is supplied in the water tray. To
assemble it, you need a support bridge
allowing the lifting of 100kg.
Tie up the head to the lifting device. The two
lifting points are the water nozzles fixing plate
on the blade guard, and the hook on the
electric motor. The two lifting strands must be
1 metre long for the one on the blade guard
and 80cm for the one on the motor.
Place the head on the two posts of the frame,
so that the threaded rods pass through the
holes designed for this purpose in the head.
Tighten the M20 (1) nuts to fix the head.
Then tighten the adjustment bar on the back of
the head (1) with the M8 screw supplied for
this purpose.
