Maintenance
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 specifications
that the hydraulic oil must meet to provide the
needed lubrication and cooling for the unit’s hydraulic
components .
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) classification 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 filters must also be changed at this time.
3 . Lubricate all grease points . Make sure all grease
cavities have been filled with grease.
4 . Top off all fluid levels to minimize condensation
during storage .
5 . Inspect all air and hydraulic hoses, couplers, fittings
and cylinders. Tighten any loose fittings and replace
any hoses that are worn .
6 . Check all safety decals . Replace any decals that are
damaged or illegible .
7 . Store the unit where it will be protected from
adverse weather conditions . All replacement parts,
whether complete assemblies, component repair
parts or service kits should be stored in a dry
sheltered area .
8 . Fill the pump and spraybar with solvent (see Clean-
out Mode in Section 6) .
9 . If a unit will not be used for more than two months,
(see Maintenance Intervals Chart in Section 7) .
Follow the procedure for the monthly interval, as
well as these preventative maintenance procedures:
Check for Water in Hydraulic Fluid - Any machine that
is stored for an extended period in a climate that has a
wide range of temperatures and/or humidity, will develop
condensation on the inside of the tank walls . Check the
hydraulic fluid on a regular basis for possible moisture
contamination .
Hydraulic oil that is contaminated,
must be drained, the filter elements replaced and the
tank refilled with Rosco approved fluid. Failure to do
this could result in premature failure of the pumps
and/or motors
Warm-up and Cycling - Start and run the engine until it
is warm . Cycle all hydraulic and/or hydrostatic functions
until all components are warm and the hydraulic fluid is
up to operating temperature .
Lubrication - After the machine is warmed up, grease all
pivot points .
Protection of Exposed Cylinder Rods - During periods
of extended storage, (two months or longer), retract all
cylinder rods as far as possible . Coat with grease any
exposed part of the cylinder rod, to prevent rusting . Any
stored cylinders, all exposed seals, o-rings, etc . should
be coated with grease to prevent cracking .
