Proceed as follow to change the hydraulic oil:
1) Park the machine on a level surface
and release the residual pressure by
moving a few times all the cylinders.
Lower the boom and rest the bucket on
the floor.
2) Cool down the oil by waiting a few
minutes.
3) Remove the filling cap from the
hydraulic tank.
4) Position a suitable container under the
machine, so that the oil can flow into it.
5) Turn on the cock located under the hydraulic tank (See picture below).
6) Fill the circuit again with recommended hydraulic oil given in this manual.
7) Make sure hydraulic oil reaches the desiderate level. After the oil level has
reached his level, the hole is completely full of oil when removing the plug in
the piston pump.
8) Also check the oil level on the gauge located in the backside (See picture
below).
9) If the gauge does not mark the maximum level and in the pump the hole is
completely full, top up with oil recommended in this manual.
10) Wait a few minutes before operate the machine.
11) Move slowly every hydraulic cylinder.
12) Check again the gauge and in case it needs, refill it with more oil.
