Biodegradable Hydraulic Oils - Kesla proG 20 Manual

GRAPPLES – USER MANUAL
Change the hydraulic oil according to the instructions given by the
manufacturer of the base machine.
Cleanliness is of utmost importance in storing and handling
hydraulic oil.
Remember cleanliness also when handling spare parts and
hoses.
Fill hydraulic oil to the system always through a filter.

7.3. BIODEGRADABLE HYDRAULIC OILS

* Instead of normal hydraulic oils, oils that dissolve quicker in the
environment have been developed to minimise the damage in
case of oil leakage. Many forestry companies require the use ot
these oils in their machines.
* Normal oils cannot directly be replaced with any biodegradable
oil without changing the hydraulic components (e.g. hoses).
* Biodegradable oils are divided into three main classes:
1. Synthetic hydraulic oils based on esters (HEE)
2. Synthetic hydraulic oils based on polyglycols (HEPG)
3. Hydraulic oils based on vegetable oils (HETG) e.g.
rapeseed oils
*NOTE! The use of HETG oils is prohibited in Kesla products!
* NOTE! Before using a biodegradable hydraulic oil, consult your
oil dealer when choosing a suitable oil type and clarify its
suitability for the hydraulic components.
