ASSEMBLY AND COMMISSIONING

3.1 Assembling the motor on the rig

If you bought a complete kit, the motor quick mounting plate is already assembled on your
motor. Otherwise, you can assemble the plate on your motor:

tighten the 4 screws through the plate in the motor.

Then, assemble the motor on rig by just slipping this plate in the corresponding device on
the drilling head.

Tighten the plate on the rig using the handle.

3.2 Tool assembly

Only NORTON core bit can be used with the CDR 353.
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.
