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. Toro Premium Synthetic
Biodegradable Hydraulic Fluid is available from
your authorized Toro distributor in 19 L (5 US
gallons) pails or 208 L (55 US gallons) drums.
Checking the
Hydraulic-Fluid Level
Service Interval:
Before each use or daily
The reservoir is filled at the factory with high-quality
hydraulic fluid. The best time to check the hydraulic
oil is when the fluid is cold. The machine should be in
its transport configuration.
1.
Prepare the machine for maintenance; refer to
Preparing for Maintenance (page 43)
.
2.
Clean the area around the filler neck and the
cap of the hydraulic tank (
).

Full mark (dipstick)
2.
Add mark (dipstick)
3.
Remove the cap/dipstick from the filler neck and
wipe it with a clean rag.
4.
Insert the dipstick into the filler neck; then
remove it and check the level of fluid.
Note:
The fluid level should be within operating
range on the dipstick.
Important:
Do not overfill the tank.
5.
If the level is low, add the appropriate amount of
fluid to raise the level to the full mark.
6.
Install the cap/dipstick onto the filler neck.
Checking the Hydraulic
Lines and Hoses
Service Interval:
Before each use or daily
Check the hydraulic lines and hoses for leaks, kinked
lines, loose mounting supports, wear, loose fittings,
weather deterioration, and chemical deterioration.
Make all necessary repairs before operating.
Changing the Charge Filter
Service Interval:
Every 1,000 hours—
If you
are using the recommended
hydraulic fluid,
replace the charge
filter.
Every 800 hours—
If you are not using the
recommended hydraulic fluid or have ever
filled the reservoir with an alternative fluid,
replace the charge filter.
Important:
Use of any other filters may void the
warranty on some components.
