Lubrication
The following describes all lubricating tasks which should be performed with the superstructure.
Greasing the swivel gear
• Fill grease through the grease nipple (1) with a grease gun.
Fill approx. 50 g of grease (20-30 shots with the grease gun). See the "Recommended lubricants"
section (page 127).
• Operate the excavator and swivel the swivel frame 360° several times in succession to distribute the
grease evenly.
When moving the swivel frame, make sure no person or material is in the swivel area.
Greasing the pitch bearing
• Fill grease through the grease nipple (1) with a grease gun.
Grease at each 90° position of the pitch bearing.
Using the grease gun, apply 5 shots at every
position. See the "Recommended lubricants"
section (page 127).
When moving the swivel frame, make sure no
person or material is in the swivel area. Turn the
starter switch to the STOP position and remove the
key switch before the next greasing procedure.
• Operate the excavator and swivel the swivel frame by 90° several times. After greasing, swivel the swivel
frame 360° several times to distribute the grease evenly.
