MACHINE DESCRIPTION
Any modification, which could lead to a change in the original characteristics of the machine,
may be done only by Saint-Gobain Abrasives who shall confirm that the machine is still in
conformity with the safety regulations.
2.1 Short description
The CDR 353 core drill rig is designed for durability and high performance for onsite wet and
dry drilling operations of a wide range of masonry and natural stone products. As with all
other NORTON products, the operator will immediately appreciate the attention given to
detail and quality of materials used in construction. The machine and its component parts
are assembled to high standards assuring long life and minimum maintenance.
2.2 Purpose of use
The machine is designed for drilling a large range of building materials. It is not designed for
drilling wood or metals, except steel reinforcing securely embedded in concrete.
2.3 Layout
There are two main parts on the core drilling rig CDR 353: the motor and the rig itself.
The rig is made of sectional aluminium, which reduces the weight of the machine allowing
easy transportation. The base ensures stability of the rig, and allows two ways of fixing the
rig: using a vacuum pump or fixing anchors. The rig is equipped with a quick fixing plate, so
the motor can be fitted or removed quickly from the rig. Three different types of electric
motor are available on the CDR 353, offering excellent quality of drilling and extended life
duration. Every motor is equipped with a P.R.C.D. (Portable Residual Current Device). This
circuit breaker protects the motor from an electrical overload. The P.R.C.D. is a circuit
breaker and not a switch. Always stop the motor using its switch and not the P.R.C.D.
