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 suction strain-
ers. 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 maintained 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.
