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 20 shots at every
position. See the "Recommended lubricants" section (page 100).
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.
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 before the next greasing procedure.
Greasing the bucket bolts
Start the engine (page 53).
Position the bucket as illustrated. Lock the control lever,
stop the engine and remove the key. See the "Operating the
controls during excavation work" section (page 63).
Lubricate all grease points (1) with grease until fresh grease
emerges. See the "Recommended lubricants" section
(page 100).
Wipe emerged grease off immediately and store
dirty cleaning cloths in the containers provided for
disposal.
Checking and adjusting the crawler tension
If the crawlers are too tight, wear is increased.
If the crawlers are too loose, wear is increased and the crawlers may come off.
