Dirty oil in the system!
Damage on the equipment!
▶
Only use the specific filling point in the drive unit to fill up the hydraulic system,
see Fig. 18: Oil filling
Always pump the fluid in through the special quick connection. The quick connection
is a completely rust-proof quick release coupling, The fluid filled into the system will
be filtered through the drain filter. See Fig. 18: Oil filling.
The tank must be filled with oil to nominal level before starting for the first time,
according to Table 9: Volumes for threshold levels.

How to check oil volume during filling
• Make sure that the power to the control unit is turned on (main power switch in on
position). This will also power on the level and temperature sensor.
• Make sure that the display on the level and temperature sensor is showing the
oil level. Use the ▶ key to change between showing the oil temperature or the oil
level in the measured value display mode. For more info regarding operation of
the level and temperature sensor, see chapter 4, operation, in operation manual
RE50222-B. See item 13 in Fig. 2: Main components DOb, for position of the level
and temperature sensor on the drive unit.
• During the initial filling, the level and temperature sensor will not show changes in
the level until minimum measured value is reached (49 % / 29 liters / 8 gallons).
• Until the alarm (stop) level is reached, LED 1 will be yellow. When the alarm (stop)
level is reached, LED 1 will switch off. See Table 9: Volumes for threshold levels, for
corresponding values.
• Fill the tank until the oil level reaches the nominal value. See Table 9: Volumes for
threshold levels for corresponding values.
