Check Hydraulic System Fluid - Toro ProCore 648 Operator's Manual

Check Hydraulic System Fluid

The hydraulic system is designed to operate on anti–wear
hydraulic fluid. The machines reservoir is filled at the
factory with approximately 1.75 gallons of high quality
hydraulic fluid. Check level of hydraulic fluid before
engine is first started and daily thereafter. Appropriate
hydraulic fluids are listed below.
The following list is not assumed to be all–inclusive.
Hydraulic fluids produced by other manufacturers may be
used if they can cross reference to find an equivalent to
the products listed. Toro will not assume responsibility for
damage caused by improper substitutions, so use only
products from reputable manufacturers who will stand
behind their recommendation.
Important Use only types of hydraulic fluids
specified. Other fluids could cause system damage.
Group 1 Hydraulic Fluid (Moderate climate– average
duty)
Note: The fluids within this group are interchangeable.
Universal Tractor Hydraulic Fluid
Mobil
Amoco
Chevron
Conoco
Exxon
Pennzoil
Shell
Texaco
Important For the ProCore 648 the Group 1 fluids are
recommended for use at typical ambient temperatures of
32_ F (0_ C) to 95_ F (35_ C). The Universal Tractor Fluids
offer similar performance for those who prefer them, with
perhaps some slight loss of efficiency at high ambient
temperatures compared to the Type 46/68 fluids.
Important
For operating conditions where sustained
ambient temperatures are 95_ F (35_ C) or higher Toro
highly recommends the use of Mobil 1 15W–50 synthetic
oil.
Note: When changing from one type of hydraulic fluid to
another, be certain to remove all the old fluid from the
system, as some fluids are incompatible with others.
Group 2 Hydraulic Fluids are not recommended for
use in this application
Mobil Fluid 424
1000 Fluid
Tractor Hydraulic Fluid
Power-Tran 3
Torque Fluid
Hydra–Tranz
Donax TD

Group 3 Hydraulic Fluid (Biodegradable)
ISO VG 32/46 anti-wear hydraulic fluid
Mobil EAL Envirosyn H, ISO Grade 68
Note: This synthetic biodegradable hydraulic fluid is not
compatible with the fluids in Group 1.
Note: When changing from standard fluid to the
biodegradable type, be certain to follow approved flushing
procedures as published by Mobil. Contact your local
Toro Distributor for details.
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 4–6
gal. of hydraulic fluid. Order Part No. 44–2500 from your
Authorized Toro Distributor.
