Gremo1050F4 Instruction manual 10 Hydraulic system
10.1 General
Hydraulic oil level check
Fig. 141 Hydraulic tank level check
The hydraulic oil level is checked either in the sight glass
on the hydraulic tank’s left side or in GreControl.
In the sight glass the level should be between the marks.
Top up with oil if the level is too low. See the service and
maintenance section for volumes and quality, volume
specifications and oil recommendations. GreControl
triggers an alarm if the hydraulic oil level drops below the
factory-set alarm level. (See Chapter 4, Instruments and
controls and Engine transmission and crane control
system)
NOTICE
When changing the hydraulic oil, the return filter and
breather filter should also be replaced at the same time.
Refilling hydraulic oil
NOTICE
When filling up with hydraulic oil, the machine must be
on a level surface. Do not mix different types of hydraulic
oil; check which type of oil the machine is already using
before topping up.
Fig. 142 Refilling hydraulic oil
The hydraulic oil tank (1) is filled using an electric refilling
pump (2). By inserting the filling hose (3) in the oil drum
with new hydraulic oil, the oil passes through the return
filter (4) before it enters the hydraulic tank.
Press the right-hand start button (7) on the control panel
(5) to start the refilling pump and when the oil level
reaches the maximum level the pump stops. Press (6) to
manually stop the pump. The switch (8) controls the diesel
filling pump and (9) controls the vacuum pump (OPTION).
NOTICE
New oil in new barrels or cans is seldom clean enough to
fulfil the requirements. All filling of hydraulic oils should
therefore be done with the electric refilling pump.
NOTICE
Never fill hydraulic oil directly at the cap. Dirty and
unfiltered hydraulic oil may cause damage to the
machine!
