Question by: Janet P on Jan 21, 2026, 8:53 AM

What kind of hydraulic fluid do these motors need? Gotta make sure I'm using the right stuff.

Answer by: Customer Support on Jan 22, 2026, 11:34 AM

These S Series Geroler motors require a premium quality, anti-wear type hydraulic fluid. It should be maintained at a minimum viscosity of 70 SUS at operating temperature, and the fluid cleanliness maintained to ISO Cleanliness Code level 18/13.
