3 ASSEMBLY AND COMMISSIONING

3.1 Assembling the motor on the rig

To assemble the motor on the collar, loosen the tightening screw. Then fit the motor in the collar.
Retighten the screw so the motor cannot move in the collar.

3.2 Tool assembly

Only NORTON core bit can be used with the CDR 133.
All tools used must be selected with regard to their maximum permitted cutting speed for the
machine's maximum permitted rotation speed.
Before assembling a new bit into the machine, switch it off and isolate it from the main source of
electricity.
To assemble a new bit, follow these steps:

Remove the motor from the rig.

Use two spanners to dismount the old bit: one to lock the motor axle, and the other to unscrew
the bit. Do not grip on threaded parts.

Grease the thread of the motor axle and of the bit.

For bits with a 1¼'' fitting, insert a bronze or brass washer between the motor axle and the core
bit.

Adapters are available in case core bit and motor axle do not fit together.

Screw the new core bit. Tighten using the two spanners. Check that it is completely locked on
the motor axle.

3.3 Electrical connections

Electrical connections
Check that,

the voltage/phase/current supply corresponds to the information indicated on the motor plate.

available power supply has a ground connection in conformity with safety regulations. If you
have any doubt, let a qualified electrician verify your installation.

the connecting cables should have at least a 2.5mm
Security Device P.R.C.D.
This circuit breaker must be connected to an electrical supply having the neutral connector and the
earth connector separated. If there is a connection between these two connectors anywhere on the
electrical net, the P.R.C.D. will automatically cut the circuit.
Therefore, check with a qualified electrician, that this separation is correctly made on your electrical
system.
If you use extension cables, make sure they have three wires.
This device can be uncertain with a generator. Ask the manufacturer of the generator if the coils are
properly separated.
