8.6 HYDRAULIC SYSTEM FLUSHING
When changing from mineral to vegetables oil
Terresolve ™ EnviroLogic ® BioFlush is a carefully
designed fluid which helps to flush and remove
petroleum oil from hydraulic systems. This is done
when converting hydraulic systems to the use of
biodegradable fluids.
EnviroLogic ® BioFlush will condition the internal
hydraulic system to help optimize both overall system
performance and fluid biodegradability.
1. Run equipment until warm. Drain petroleum
hydraulic fluid and replace all hydraulic filters.
2. Fill system with EnviroLogic. BioFlush. Run
equipment for 5 minutes until fluid is
completely circulated.
3. Drain the BioFlush and replace hydraulic
filters.
4. Fill system with approved biodegradable ISO
VG 46 hydraulic oil.
The hydraulic system is now optimized for fluid
biodegradability in the event of leakage.
