High Viscosity Index/Low Pour Point
Anti-wear Hydraulic Fluid, ISO VG 46 (cont'd.)
Pour Point, ASTM D97
-37°C to -45°C (-34°F
to -49°F)
Industry Specifications:
Eaton Vickers 694 (I-286-S,
M-2950-S/35VQ25 or
M-2952-S)
Note:
Many hydraulic fluids are almost colorless,
making it difficult to spot leaks. A red dye additive for
the hydraulic fluid is available in 20 ml (0.67 fl oz)
bottles. A bottle is sufficient for 15 to 22 L (4 to 6 US
gallons) of hydraulic fluid. Order Part No. 44-2500
from your authorized Toro distributor.
Important:
Toro Premium Synthetic
Biodegradable Hydraulic Fluid is the only
synthetic biodegradable fluid approved by Toro.
This fluid is compatible with the elastomers used
in Toro hydraulic systems and is suitable for a
wide-range of temperature conditions. This fluid is
compatible with conventional mineral oils, but for
maximum biodegradability and performance, the
hydraulic system should be thoroughly flushed of
conventional fluid. The oil is available in 19 L (5
US gallons) pails or 208 L (55 US gallons) from
your authorized Toro distributor.
Checking the Hydraulic
Fluid
Service Interval:
Before each use or daily Check the
level of the hydraulic fluid before
the engine is first started and daily
thereafter.
Important:
If the fluid becomes contaminated,
contact an authorized Toro distributor to have the
system flushed.
Contaminated fluid looks milky or black when
compared to clean fluid.
1.
Position the sprayer on a level surface, engage
the parking brake, shut off the spray pump, shut
off the engine, and remove the key.
2.
Clean the area around the hydraulic-fluid-tank
dipstick cap and remove it (
).

Important:
Be very careful not to get dirt or
other contaminants into the opening when
checking the fluid.
3.
Wipe the dipstick clean with a cloth and replace
it completely in the tank.
4.
Remove the dipstick from the filler neck and
check the fluid level (
).
Note:
The fluid level should be at the lower
mark on the dipstick when the fluid is cold.

If the fluid is low, fill the tank with the specified
hydraulic fluid to raise the level to the lower
mark; refer to

6.
Install the dipstick cap into the tank and secure.
Replacing the Hydraulic
Filters
Service Interval:
Every 1,000 hours—
If you
are using the recommended
hydraulic fluid,
