3 ASSEMBLY AND COMMISSIONING
Before beginning the work with the C51, you have to assemble some parts.
3.1 Assembly
Secure t
he operator’s handle in a comfortable user position by using the locking nut.
3.2 Tool assembly
Only use NORTON blades with the C51.
A blade with a maximum diameter of 350 mm can be fitted in the C51.
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 wheel until the cutting head is in the raised position.
Disconnect the water tank.
Loosen the side screw and remove the blade guard.
Loosen the hexagonal nut 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 the shaft 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.
Remount the blade guard.
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 the water tank with clean water.
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.
