Check Hydraulic System Fluid - Toro Greensmaster 3200 Service Manual

Check Hydraulic System Fluid

The hydraulic system is designed to operate on anti-
wear hydraulic fluid. The machine's reservoir is filled at
the factory with Mobil 424 hydraulic fluid. Check level
of hydraulic fluid before engine is first started and
daily thereafter (see Specifications for capacity).
IMPORTANT: Two groups of hydraulic fluid are spe-
cified to allow optimal operation of the machine in
a wide range of temperatures encountered. The
group 1 fluids are a multiviscosity hydraulic fluids
which allows operation at lower temperatures with-
out the increased viscosity, which is associated
with straight viscosity fluids.
Note: The fluids in this Group 1 are interchangeable.

ent temperatures consistently below 100 F.):

Using the Mobil 424 type fluids in the higher ambient
temperatures may result in decreased efficiency in
some of the hydraulic components compared to using
the Mobil DTE 26 type fluids.
The Mobil DTE 26 type fluids are straight viscosity fluids
which remain slightly more viscous at higher tempera-
tures than the multiviscosity fluids.
Using the Mobil DTE 26 type fluids in the lower ambient
temperatures may result in harder starting, increased
engine laboring while cold, sluggish or malfunctioning
valve spools while cold and increase filter back pressure
due to the higher fluid viscosity.
It is recommended that you select which set of condi-
tions (either ambient temperatures above 70 F. or be-
low 100 F.), and use that type of fluid throughout the
year, rather than changing fluid types several times per
year.
Group 3 Hydraulic Fluid (Biodegradable):
ISO VG 32/46 antiwear hydraulic fluid
Mobil
Note: This biodegradable hydraulic fluid in this group
is not compatible with the fluids in group 1 or 2.
Note: Using biodegradable hydraulic fluid requires
the installation of a Oil Cooler Kit, Toro Model No. 04499
to traction unit.
IMPORTANT: When changing from one type of hy-
draulic fluid to the other, be certain to remove all the
old fluid from the system, because some brands of
one type are not completely compatible with some
brands of the other type of hydraulic fluid.
IMPORTANT: Use only types of hydraulic fluids
specified. Other fluids could cause system damage.
Note: A red dye additive for the hydraulic system fluid
is available in 2/3 oz. bottles. One bottle is sufficient for
4 to 6 gal of hydraulic fluid. Order Part No. 44–2500 from
your Authorized Toro Distributor.
