8.4.2. Lubrication of the upper column bearing
DANGER
The upper column bearing must be lubricated while the crane is slewed. If one
person lubricates the upper column bearing, while another is slewing the crane:
Take care that the person lubricating the bearing does not come into contact or get
crushed by the crane!
If you are lubricating the upper column bearing without
help:
• Lubricate the upper bearing with a little grease.
• Slew the crane a little.
• Again lubricate with a little grease. Repeat, until the
column has been slewed round completely.
