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).
