Hydraulic Oil - Toro Reelmaster 5100-D Service Manual

Hydraulic Oil

The hydraulic system was initially filled at the factory
with Mobil 424 oil.
Two groups of hydrauic oil are specified to allow optimal
operation of the machine in a wide range of tempera­
tures encountered.
The group 1 oil are a multi-viscosity hydraulic oil which
allows operation at lower temperatures without the in­
creased viscosity, which is associated with straight vis­
cosity oils.
The group 2 type oils are straight viscosity oils which
remain slightly more viscous at higher temperatures
than the multi-viscosity oils.
Using group 1 oils in higher ambient temperatures may
result in decreased efficiency in some of the hydraulic
components compared to using group 2 oils.
Using group 2 oils in lower ambient temperatures may
result in harder starting, increased engine laboring while
cold, sluggish or non-operating valve spools while cold
and increased filter back pressure due to the higher oil
viscosity.
It is recommended that you select which conditions
(either ambient temperatures above 70°F or below
100°F) and use that type of oil throughout the year,
rather than changing oil types several times per year.
NOTE: When changing from one type of hydraulic oil to
the other, be certain to remove all the old oil from the
system, because some brands of one type are not
completely compatible with some brands of the other
type of hydraulic oil. If you always use Mobil products,
the two types of oil are compatible and interchangeable.
IMPORTANT: Use only types of hydraulic oils speci ­
fied. Other fluids could cause system damage.
NOTE: A red dye additive for the hydraulic system oil is
available in 2/3 oz. bottles. One bottle is sufficient for 4
to 6 gallons of hydraulic oil. Order Part No. 44-2500 from
your Authorized Toro Distributor.
