Maintenance 6.1-6
6.1-6 Hydraulic fluids
For the selection of hydraulic fluids you should get in touch with your service partner.
HLP / ISO hydraulic fluids wth the following properties should be used:
•
favourable viscosity/temperature behaviour.
•
good thermal and mechanical loading properties.
•
extensive resistance to ageing.
•
good corrosion protection.
•
adequate cold flowability.
•
adequate lubrication effect in the marginal lubrication area.
•
good air release properties.
•
excellent foam behaviour.
•
neutrality in contact with seals and hydraulic hoses.
As the viscosity of hydraulic fluids changes considerably through fluctuations in temperature,
compromises cannot be avoided in their selection. For your PALFINGER crane the following limit
values apply:
•
High temperatur range: 10 cSt
•
Cold start limit: 1000 cSt
•
Purity class: 15/12 (to ISO 4406)
