1. Control of hydraulic oil
Oil level in the tank needs to be controlled occasionally.
Oil level in the tank is 1,9 liters.
For hydraulic system, oil for hydraulic systems ISO 32 is used. In summer months, when the
ambient temperature surpasses 25 °C, oil ISO 46 needs to be used. First oil change needs
to be done after 1000 hours of operation. Each next oil change must occur after 1000
hours of operation or at least once a year. During operation, oil temperature needs to be
controlled. It this surpasses 70 °C, the cardan must be stopped and the reason of
overheating must be determined. If you do not have a thermometer present, you can
check the oil temperature by touching the hydraulic line. This can be done only with the
engine stopped. Otherwise, the hydraulic system can malfunction.
Oil level is controlled with a gauge on the tank cover (figure 13, pos. 3). This is the place,
where oil is filled.
For any kind of intervention in the hydraulic system, you must release pressure in the
system. This is achieved by pressing the left button on the control console (pos 1, figure 8),
until the pressure drops to 0 bar (pos 1, figure 14).
Before starting, you must first remove both the triangular protection from the winch column
and the PTO protection. Drain the oil from the reservoir (figure 13) at the pipe which is
installed between the pump and tank. At the bottom of the reservoir you can
find a filter
that needs to be replaced every time you change the oil. It is also necessary to clean the
high pressure filter (pos 2, figure 14).
