To limit the hydraulic oil contamination when working under extreme dusty conditions.
In order to avoid any premature wear and failure of hydraulic components in
consequence of this contamination reduce the oil change intervals as described above and, in
addition, observe following recommendations:
1.
The tank return filer element must be replaced every 100 working hours.
2.
The tank return filer must be fitted with lower (finer) micron filter element ( 10 um
instead of 30 um).
3.
The breather filter on the hydraulic tank must be replaced with a 3 um fine breather
filter.
4.
The 3 um breather filter must be replaced every time when the hydraulic oil is
changed (every 500 working hours).
CHECK THE HYDRAULIC OIL LEVEL
When checking the oil level, park the machine on the level ground, put down the boom ,
stick and rest the bucket on the ground with stick and tilt cylinders fully extended.
In this position, the oil level must not drop below the middle level on the sight gauge or
oil must be added to the tank until reaching this level.
Level “MAXI” shows the maximum oil level when all cylinders are retracted.
Level “MINI” shows the minimum oil level when all cylinders are all the way extended.
TO DRAIN AND TO ADD OIL TO THE HYDRAULIC TANK
The hydraulic system should always be refilled or drained using a filler pump.
CAUTION!
Before draining the oil or opening the hydraulic tank, you always must first unscrew the
breather valve one turn to relieve the tank pressure.
