OPERATING THE MACHINE

You will find useful description of how to use the machine properly.

5.1 Site of work

5.1.1 Siting the machine

Remove from the site anything, which might hinder the working procedure!

Make sure the site is sufficiently well lit!

Observe the conditions for connecting to power supplies!

Place electric cables in such a way that damage by the CDR 353 is excluded!

Make sure you have a continual adequate view of the working area so you can intervene
in the working process at any time!

Keep other staff out of the area, so you can work securely.
5.1.2 Space required for operation and maintenance
Leave 2 m around the machine for usage and maintenance of the CDR 353.

5.2 Drilling method

5.2.1 Preparing the cut

Make sure that it is well anchored or clamped firmly when the material to be drilled is not
part of a big construction.

Before drilling a reinforced-concrete construction, make sure you will not damage the
structure.

Make sure the drilling will not damage any gas or plumbing pipelines, or electrical wires.

Only use the plastic handle of the machine, and no metal parts, to operate the CDR 353,
especially when electrical wires might be submerged.

Make sure before drilling that the core will not cause damage to anything or anyone by
falling out of the hole. Always delimit and sign the working area and place warning
signals around it.

If the core can cause damage by falling out of the hole, make the right framework to hold
the core when you stop drilling.

To choose the core bit rotation speed, use the graph on page, which gives the range of
speed to use according to the diameter of the hole.

Before starting your work, check the fixing and stability of the core bit.

Use the right tools as recommended by the manufacturer depending on the material to
be drilled and the required efficiency.

Apply cooling water continuously whilst drilling and in good time!
5.2.2 Fixing the rig
Only use NORTON tools to fix the rig. Always fix the rig before assembling the motor on the
rig. When drilling overhead or horizontally into a wall, only use dowels to fix the rig. Extra
safety provision should be made with the use of a support sling to the drilling rig, in case of
failure of anchor.
