Slewing bearing
1. Remove the cover (1).
2. Put grease on the teeth on the slewing bearing with a
brush through the hole (2).
3. Slew the crane a bit and put grease again.
4. Make sure that the slewing bearing is fully greased.
5. Install the cover again in the same direction.
Bearing assembly
The grease filling is there to reduce friction, seal the bearing and provide protection against
corrosion.
• The operator has to grease the bearing assembly approximately every 100 working hours.
• Lubrication is made by injecting approximately 5 cm
3
into each grease nipple (3) around the
bearing.
8.4.5. Lubrication of the boom system
Clean the surfaces and remove with a spatula all abrasive material (dirt, sand, shavings), and
where possible, the old grease.
Procedure:
• Grease externally the extensions in the low part (less in the upper and side parts).
• Grease internally the extensions in the upper part (less in the lower and side parts).
• In order to internally grease, use the side holes in the extensions (if fitted) and the back closing
plate slots.
• Grease the sliding block area (if fitted) with the extensions retracted and also through two
specific greasing points.
