4.7.13.b CHANGING THE OIL IN THE SWING REDUCTION GEAR
DANGER
• Soon after the machine has been stopped the oil is very hot; let the oil cool down until it reaches a tem-
perature of 40-45°C before changing it.
• Oils, filters, coolants and batteries are considered special waste and must be collected and disposed of
according to the anti-pollution regulations in force.
CAUTION
• On new machines, change the rotation reduction gear oil
after the first 250 hours of operation and successively eve-
ry 2000 hours.
This operation must be carried out with the machine on level
ground at a temperature of 40-45°C, so that the oil is more fluid
and can be drained easily together with the suspended solid parti-
cles.
1 - Rotate the upper structure by 90°, in such a way as free the
lower right cover from the machine tracks.
2 - Open the side cover. (See “3.5.2 SIDE COVER”).
3 - Remove the lower right cover in order to create room for the
drain pipe (1).
Use a 17 mm spanner.
4 - Remove the drain plug (2) and let the used oil flow out com-
pletely, collecting it into a container with suitable capacity.
While the oil flows out, remove the level plug (3).
Use 16 and 19 mm spanners.
5 - Once the oil has been drained, put back the plug (2), the lowe
right cover and fill with the prescribed oil through the hole (3),
until reaching the MAX level indicated on the graduated dip-
stick (3).
6 - Put back the plug (3) and close the side cover.
Rotate the upper structure more than once and check the level
again with the machine at rest.
Use only the prescribed type of oil. (See “4.3 FUEL, COOL-
ANT AND LUBRICANTS”).
