4.7.7 MAINTENANCE EVERY 100 HOURS OF OPERATION
4.7.7.a LUBRICATING THE BALL-BEARING RING
These operations must be carried out together with the operations to be performed EVERY 50 HOURS.
The lubrication of the ball-bearing ring must be performed after
carefully cleaning the grease nipples (1), applying the prescribed
grease by means of the the greasing pump supplied with the ma-
chine. (See “4.3 FUEL, COOLANT AND LUBRICANTS”).
Once lubrication has been carried out, make sure that all the
points have been duly greased and then remove any excess
grease that may have come out of the ball-bearing ring.
IMPORTANT
☞
•
Inject grease in all the grease nipples (2 grease nipples po-
sitioned at 180° from each other), in order to have correct
distribution and a sufficient quantity of new grease.
