1 BASIC SAFETY INSTRUCTIONS

The CM 42 is exclusively designed for the cutting of construction products mainly on construction

sites.

Uses other than the manufacturer's instructions shall be considered as contravening the regulations.

The manufacturer shall not be held responsible for any resulting damage. Any risk shall be borne

entirely by the user. Observing the operating instructions and compliance with inspection and

servicing requirements shall also be considered as included under use in accordance with the

regulations.

1.1 Symbols

Important warnings and pieces of advice are indicated on the machine using symbols. The following

symbols are used on the machine:

Read operator's instructions

Ear protection must be worn

Hand protection must be worn

Eye protection shall be worn

Rotation direction of the blade

Danger: risk of cut

1.2 Machine plate

Important data can be found on the following plate located on the machine:

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.

Check for correct mounting of the blade regularly.

Immediately remove damaged or badly worn blades, as they endanger the operator whilst

rotating.

Only fit NORTON diamond blades to the machine! The use of other tools can damage the

machine!

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.

Use of ear and hand protection is compulsory.

For security reasons, never leave the machine unattended, untied or unlocked.

While the engine is running

Do not move the machine whilst the blade is running idle.

Always cut with the blade guard in position.

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 CM 42 Masonry 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 CLIPPER 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 wet and dry cutting of a large range of building and refractory

materials, or tiles. It is not designed for cutting wood or metals.

2.3 Layout

VERS. 2015.07.06 CM 42_MAN_EN

Frame and feet (1)

The frame is made of a jig-welded reinforced steel construction to ensure perfect rigidity. 4

removable legs fit into housings welded on frame sides and locked into place with wing screws. The

front feet are adjustable. It is also equipped with wheels and handles for transportation.

Cutting head (2)

Spring loaded jig-welded steel console. The motor fixing points and the pivot are machined for

perfect fit. A locking system allows straight-through cutting without any other accessory.

Blade guard (3)

Jig-welded steel construction with 400mm-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 removed to allow easy

access to shaft for inspection and blade replacement when motor is switched off, while fully

protecting the blade when in operation.

Electrical motor (4)

2.2 kW (1.8 kW for 115V) electrical motor with an overload protection. Low voltage trigger (NVR)

built in the switch prevents the motor to restart for example after a power cut. 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.

The ON-OFF switch also serves as emergency stop.

Conveyor cart (5)

Steel welded construction with non-slip top. As an accessory, a conveyor can tilt from 0 to 45º for

angle bevel tile cutting.

The machine guide system permits precise cuts to be made by virtue of four roller sheaves set at an

inclination to compensate for wear. The nylon-plastic sheaves and sealed-bearings permit easy

operation. Precise positioning of the material is possible thanks to the large surface area of the

conveyor cart and the variable angle guide-a-cut. The table has an anti-dumping system and a

locking latch.

Water cooling system (6)

The coolant system comprises:

A powerful, submersible electric 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 on the blade guard ensure adequate flow of water to both sides of

the cutting blade.

A water curtain, fixed to head axle restricts water spray and minimizes water loss.

The pump switch is located on the right side of the main switch.

Attention: The water pump must never run without water.

The vibration value is lower and does not exceed 2.5 m / s.

Values determined using the procedure described in the standard EN 12418.

The measurements are made with new machines. Actual values may vary with site conditions, in

terms of:

Materials worked

Wear Machine

Lack of maintenance

Inappropriate tool for application

Tool in poor condition

Unskilled operator

Etc…

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…
