5.4 HYDRAULIC TANK
The hydraulic tank has a capacity of 53.3 gallons (201.7
liters) and includes the hydraulic return filter and two suc-
tion strainers. It is normal for the oil level to appear low
when the boom is raised and should only be checked with
the machine on level ground and with the boom fully
retracted and lowered. The hydraulic oil should be main-
tained at the full level as shown by the decal and hydraulic
oil level gauge located on the side of the tank as shown in
Figure 5-28., Hydraulic Oil Level Gauge. This decal shows
the proper full level for both hot and cold oil. Do not fill the
hydraulic tank past the appropriate full mark. Overfilling
can cause the oil to overflow from the top of the hydraulic
tank during emergency lowering operations.
