HYDRAULIC FLUIDS
The below recommended hydraulic oils have been
reviewed by Rosco and are recommended as
replacements. It is best to use the heaviest weight
oil that can be safely used for the temperature
range of machine operation. If your machine will
never be used at below 0°F temperatures, we
HYDRAULIC OIL REQUIREMENTS AND APPROVED BRANDS FOR FIELD FILL:
DO NOT MIX manufacturers or grade
weights when adding hydraulic oil.
Be sure
hydraulic oil selection is compatable with
your hydraulic system.
Be sure
to use mineral base hydraulic oil.
Be sure
hydraulic oil selection assistance is from
a reputable supplier.
Be sure
the hydraulic specifications meet or
exceed the following specifications.
Hydraulic oil must provide anti-wear properties
that meet or exceed those found in the API
(American Petroleum Institute) classification SD,
SE or CC crank case oil.
Hydraulic oil viscosity must not fall below 70 SUS
(13 cs) in the reservior under the most adverse
conditions. The best viscosity being 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 with oil other than the
specific factory fill oil listed below, 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 filters
must also be changed at this time.
recommend that you use a heavier weight oil.
If you are considering using an oil that is not listed,
contact the Rosco factory to obtain the
specifications that the hydraulic oil must meet to
provide the needed lubrication and cooling for the
units’ hydraulic components.
