LUBRICATION OF THE SWING RING TEETH
A housing around the pinion of the swing gear contains all the necessary lubrication
reserves for the swing ring teeth lubrication.
There is a cover on the right side of the swing platform. Remove the cover, connect a
grease gun to pump the grease about 20 times through this hole and then turn the
upper-carriage by 360
º
.
Under normal working conditions, the
swing ring teeth need to be lubricated per 500 working hours.
LUBRICATION OF THE BALL BEARING RACE
Under normal working conditions, the ball bearing race must be lubricated weekly.
Add approx.10 stroke of greases of grease with the grease gun into each of the grease
fittings.
If the machine is used under hard conditions or in multi-shift service, lubricate more
often ( up to once a day).
LUBRICATION OF ATTACHMENT BEARING POINTS
The main lubrication points are as follow: Cylinders and boom, stick, bucket connection,
connection between boom and upper-carriage. Every lubrication point should be added
sufficient grease.
To lubricate the attachment, add grease on every grease fitting until clean grease runs out
of the corresponding bearing point.
Under normal working conditions, perform a complete lubrication of attachment weekly.
If the machine is used under hard conditions or in multi-shift service, lubricate more
often ( up to once a working shift).
HYDRAULIC OIL CHANGE INTERVALS
Note: Oil change in present intervals is only permitted for mineral oils. When using
environmentally friendly hydraulic fluids, oil sample analysis reports must be used to
determine the time of the oil change.
