8.4.2. Greasing the upper column bearing and three-point bridge
DANGER
The upper column bearing must be grease while the crane is slewed.
NOTE
The lubrication points can be fitted differently than showed in the image.
Grease through the nipples in the greasing manifold,
located on the crane base, according to the greasing signs.
If the manifold does not exist, grease directly through the
nipples, located on the upper column bearing.
Niples (1): For greasing upper column bearing

If you are greasing the upper column bearing without
help:
1. Grease the upper bearing with a little grease.
2. Slew the crane a little.
3. Grease it again and repeat until the column has
completed one turn.
If you are greasing the upper column bearing with help:
One person greases the upper column bearing, while another carefully slews the crane.
