Operator's instructions
3. Daily checks
Before each shift starts an extra and thorough visual safety check should be carried
out in order to detect:
• Damage that could give rise to structural weakness or cracks.
• Wear that could have the same consequences.
• Cracks or fractures in materials or welded joints.
If the drill rig has been subjected to abnormally high stresses, vital load-bearing com-
ponents may have been damaged. From a safety viewpoint, it is therefore especially
important to check the following points (see illustration: Check points).
