Replacement of return filter hydraulic oil
The return filters are placed on the right hand side of the hydraulic
tank, at the refill lid.
SMV 33-1,200B – 60-1,500 B are equipped with two filter sets.
BE CAREFUL
Adhere to these instructions, otherwise the
hydraulic system might be damaged.
• Remove the first step.
• Carefully clean around the filter lid (1).
• Remove the filter lid.
• Loosen the filter housing down in the return chamber by the
four screws.
• Lift up the filter housing (2) together with the filter elements (3).
NOTE
Do not take the filter apart inside the tank.
• Remove the elements by pushing and turning the by pass valve (4).
• Check that the valve is closed.
• If the tank is empty: check the bottom of the tank as well for
any deposits.
• Clean the filter container.
• Fit new filters and lock with the by-pass valve (4). Push and turn
to the correct position.
• Fit the filter housing in the tank.

Replacement of breathing filter for the hydraulic oil tank

Replacing of hydraulic oil
The hydraulic oil should be replaced in conjunction with a filter
replacement.
For recommended oil replacement intervals, see section
"Inspection and maintenance schedule" on page 96.
This may vary depending on the working environment of the
machine.
• Drain the oil through the drain plug (6). Use a suitable
container.
• Alternatively, the oil can be sucked up through the filter
housings, if the filters have been removed.
• Check the bottom of the tank for any deposits.
• Fit the filter and lid as per above.
• Filling of hydraulic oil is done through the filling nipple (7) in
the filter lid.
The filled oil is thereby filtered through the filters.
It is preferable if the filling can be done under some pressure.
