Remove the filter elements (2) from the breather

Wash the elements with a suitable cleaning solvent.
Also clean the inside of the breather assembly.
Shake out the excess solvent. Place the elements
in the breather and install the cover and screw.
The reservoir, the filter and the screens are located inside
the radiator shell. The subframe also serves as a reservoir.
The pump is located under the radiator shell in the front
support.
Checking the Hydraulic System Oil Level: The hydraulic
system oil level should be checked daily or every 10
hours.

system oil level with the dipstick, Figure 78.

If the oil level is low, add oil through the dipstick
opening until level with the "FULL" mark on the
dipstick. See page 70 for the type of oil to use.
Cleaning the Hydraulic System Oil Breather: The hy-
draulic system oil breather should be cleaned every 50
hours.
