Hydraulic oil
Note!
PALFINGER recommends the use of biodegradable oil. Even
biodegradable oil must not be released into the environment.
Required characteristics
Hydraulic oil Operating temperature
Synthetic ester (biologically degradable): approx. -30 to +80ºC (-22°F to +176°F)
Mineral oil (not biologically degradable): approx. -30 to +80ºC (-22°F to +176°F)
Use either synthetic ester (biologically degradable) or mineral oil (not biologically degradable).
The hydraulic fluid has a working range of between -30° and 80°C (-22°F and +176F), depending on
the outside temperature.
The ideal operating temperature of the hydraulic fluid is b 30 and + 60ºC (+86°F and +140°F).
Always read off hydraulic fluid temperature after using the crane.
If this temperature range is exceeded frequently, please contact a PALFINGER service partner.
