Maintenance
Relieving the pressure of the hydraulic system:
•
The unit must be switched off and the power supply disconnected.
•
Secure the unit against being switched on unintentionally.
•
Push all operating levers in both switching positions several times.
The pressure in the hydraulic system is relieved apart from possible residual pressures.
Warning!
Let the hydraulic oil cool down sufficiently to prevent scalding.
Operating hours counter
The counter’s display shows the total number of operating hours, the number of hours until the next
service and the number of hours until the next scheduled maintenance.

1 Display starts blinking when it gets down to
100 hours of use.
2 Solid red light stays on from 0 hours of use.
The operating hours counter counts down from 500 to 0. As of 100, the display starts to flash. From 0
the solid red light comes on and stays on.
Using the minus sign, the counter then counts up from 0 (-1, -2, -3 etc.).
After the crane is turned on (power supply), its total operating hours are shown on the display for 10
seconds.
After this period, the display shows the number of operating hours until the next service.
The service must be carried out by a PALFINGER service workshop at around 0 hours and logged
accordingly in the service manual.
If the crane is used for less than 500 hours a year, a service must be arranged at least once annually.
After the service has been done, the service workshop resets the operating hours counter to 500
hours.
