Checking The Hydraulic System; Filling The Fuel Tank - Toro Groundsmaster 3320 30307 Operator's Manual

Checking the Hydraulic System

The machines reservoir is filled at the factory with
approximately 5 quarts (4.7 l) of high quality hydraulic
fluid. Check the level of the hydraulic fluid before the
engine is first started and daily thereafter. The
recommended replacement fluid is:
Toro Premium Transmission/Hydraulic Tractor
Fluid
(Available in 5 gallon pails or 55 gallon drums. See
parts catalog or Toro distributor for part numbers.)
Alternate fluids: If the Toro fluid is not available, other
petroleum–based Universal Tractor Hydraulic Fluids
(UTHF) may be used provided its specifications fall within
the listed range for all the following material properties and
it meets industry standards. We do not recommend the use
of synthetic fluid. Consult with your lubricant distributor to
identify a satisfactory product Note: Toro will not assume
responsibility for damage caused by improper substitutions,
so use only products from reputable manufacturers who
will stand behind their recommendation.
Material Properties:
Viscosity, ASTM D445 cSt @ 40_C 55 to 62
cSt @ 100_C 9.1 to 9.8
Viscosity Index ASTM D2270 140 – 152
Pour Point, ASTM D97
Industry Specifications:
API GL–4, AGCO Powerfluid 821 XL, Ford New
Holland FNHA–2–C–201.00, Kubota UDT, John Deere
J20C, Vickers 35VQ25 and Volvo WB–101/BM.
Note: Many hydraulic fluids are almost colorless, making it
difficult to spot leaks. A red dye additive for the hydraulic
system oil is available in 2/3 oz. (20 ml) bottles. One bottle
is sufficient for 4–6 gal (15–22 1) of hydraulic oil. Order
part no. 44–2500 from your authorized Toro distributor.
1. Position machine on a level surface. Place all control in
neutral position and start the engine. Run engine at
lowest possible RPM to purge the system of air. DO
NOT ENGAGE PTO. Cycle steering wheel several
times fully to the left and right. Raise the deck to extend
lift cylinders, aiming steering wheels straight forward
and stop the engine.
2. Remove dipstick cap (Fig. 16) from filler neck and wipe
it with a clean rag. Screw dipstick cap finger-tight onto
filler neck; then remove it and check level of fluid. If
level is not within 1/2 inch (13 mm) from the groove in
the dipstick (Fig. 16), add enough high quality
hydraulic fluid to raise level to groove mark. Do not
overfill.

not recommended to tighten cap with a wrench.
4. Check all hoses and fittings for leaks.

Filling the Fuel Tank

Fuel tank capacity is approximately 12.8 gallon (48.5 l).
1. Using a clean rag, clean area around fuel tank cap.
2. Remove cap from the fuel tank (Fig. 17).
