HYDRAULIC SYSTEM
Oil Change procedure
Fig.19
The hydraulic oil must be changed if:
•
The filter indicator needle enters into the ‘RED
ZONE’, and the oil operating temperature
exceeds 100 deg. F.(38 deg. C.).
•
Or every 1000 hours.
•
The oil has a ‘milky’ appearance, ie. Indicating
that there is water in the oil.
•
It has been subjected to ‘over heating’.
•
A hydraulic component has ‘failed’. Possibly
depositing metal debris into the system.
IMPORTANT
If the oil appears to have water contamination, it must be
removed from the system by a qualified hydraulic service
center,
as soon as possible.
OIL LEVEL
Check the oil level in the sight gauge. It should be at the
‘half full’ mark with all cylinders retracted, legs extended-
when applicable, and the oil ‘warm’.
Fig.19
‘START- UP’ procedure after oil change.
The oil in the lines, cylinders, valves and pump will be
cleaner than the new oil. To minimize contamination do
not operate any of the controls until the following
procedure has been carried out.
Start the engine. Allow it to ‘idle’ for at least 20 minutes.
This allows the new oil to circulate through the pump and
filter only, before flowing into the system when the
controls are operated.
