Measurements are made with new machines. Real values in the field could vary the simple
one with the double according to operating conditions, depending on:
oMaterial
oCutting depth
oMachine wear
oLack of maintenance
oTool not adapted to application
oTool in bad shape
oNon-specialised operator
Vibrations exposure time depends on cutting performance too
(adaptation machine / tool / 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…

3.2 Tool assembly
Only NORTON blades with a maximum diameter of 450 mm can be fitted on the CS 451 E.
A blade with a maximum diameter of 450 mm can be fitted. 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, switch the machine off.
To mount a new blade, follow these steps:
Turn the hand wheel until the pivoting frame is in the raised position.
Loosen the screws maintaining the guard and turn the blade guard open.
Loosen the hexagonal nut (attention: left hand thread).on the blade shaft, which holds the
removable outer flange. Remove the nut and the outer flange Remove the nut and the outer
flange.
Clean the flanges and blade shaft and inspect for wear.
Mount the blade on the shaft ensuring that direction of rotation (arrow on blade steel centre) is
correct. Wrong direction of rotation blunts the blade quickly.
Put in place outer blade flange.
Tighten hexagonal nut with spanner supplied for this purpose (left hand thread).
Close the blade guard and tighten the screws.
ATTENTION! The blade bore must correspond exactly to the blade shaft. Cracked or damaged bore
is dangerous for the operator and for the machine.
3.3 Water cooling system
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 delivered adequately to both sides of the blade,
as insufficient water supply may result in premature failure of the diamond blade.
In case of frost, empty the water cooling system.
3.4 Electrical connections
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.
