Hydraulic Oil
Requirements
DO NOT MIX manufacturers or grade
weights when adding hydraulic oil.
1. Be sure hydraulic oil selection is compatible with
your hydraulic system.
2. Be sure to use mineral base hydraulic oil.
3. Be sure hydraulic oil selection assistance is from a
reputable supplier.
Hydraulic oil must provide anti-wear properties that
meet or exceed those found in the API (American
Petroleum Institute) classication SD, SE or CC crank
case oil.
Hydraulic oil viscosity must not fall below 70 SUS (13
cs) in the reservoir under the most adverse conditions.
The best viscosity is 80-300 SUS (17 cs to 65 cs).
The viscosity rating at the lowest expected start-up
temperature should not exceed 10,000 SUS (2158 cs).
Hydraulic oil must have rust and oxidation inhibitors
that will maintain chemical stability. When changing the
hydraulic oil, the hydraulic system must be completely
drained. Be sure to purge or drain all hoses, cylinders,
valves, motors and pumps of hydraulic oil. All hydraulic
oil lters must also be changed at this time.
Hydraulic Fluids
The hydraulic oils listed in Table 7-2. Hydraulic
Fluids Chart have been reviewed by Rosco and are
recommended as replacements. It is best to use
the heaviest weight oil that can safely be used for
the temperature range of machine operation. If your
machine will never be used at temperatures below 0°F,
use a heavier weight oil.
If you are considering using an oil that is not listed,
contact the Rosco factory to obtain the specications
that the hydraulic oil must meet to provide the
needed lubrication and cooling for the unit’s hydraulic
components.
