HYDRAULIC SYSTEM -- Figures 68 to 71
Oil reservoir
A single oil reservoir is fitted for the hydraulic and hy-
drostatic systems. A baffle in the tank separates the
hydraulic and hydrostatic oils. The left-hand side P
contains the oil for the hydrostatic system. The right-
hand side Q contains the oil for the hydraulic system.
Oil level
ENSURE THAT ALL HYDRAULIC CYLINDERS ARE
RETRACTED BEFORE CHECKING THE OIL
LEVEL.
The oil level s hould be checked daily on the level
gauge R and should be kept between the marks.
If necessary, add oil through the filler opening S.
Oil and oil filter change
S After the first 100 operating hours
S Thereafter, every 400 operating hours, or an-
nually.
IMPORTANT:
The return filter T (low pressure filter) and the
high pressure filter U should be changed at
each oil change.
To change the oil and both filters, proceed as follows:
1. Clean the reservoir filler cap and surrounding
area (with compressed air, if possible).
2. Drain the oil from the reservoir at hose V.
3. Remove the ‘‘spin-on” return filter T with a filter
wrench.
4. Apply a film of oil to the gasket of the new return
filter.
5. Screw on the new return filter by hand. Tighten
firmly but DO NOT USE TOOLS.
