3.2 Tool assembly
Only NORTON blades with a maximum diameter of 500 mm can be fitted on the CS 502LV.
A blade with a maximum diameter of 500 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
Fill in the water tank with clean water.
Open tank water-tap (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 or excessive dust
generation.
If needed, adjust water flow with blade guard water tap.
In case of frost, empty the water cooling system.
