Changing The High Flow Hydraulic Oil And Filter (Tc Models Only); Raising The Box In An Emergency - Toro 07385 Operator's Manual

1. Hydraulic filter
3. Lubricate the gasket on the new filter.
4. Ensure that the filter mounting area is clean. Screw the
filter on until the gasket contacts the mounting plate.
Then tighten the filter one-half turn.
5. Start the engine and let it run for about two minutes to
purge air from the system. Stop the engine and check
the hydraulic oil level and for leaks.
Changing the High Flow
Hydraulic Oil and Filter (TC
models only)
Service Interval: After the first 10 hours—Change the high
flow hydraulic oil filter (TC models only).
Every 800 hours—Change the high flow hydraulic oil
and filter (TC models only).
The reservoir is filled with approximately 15 l (4 gallons) of
high quality hydraulic fluid. Appropriate hydraulic oils are
listed below.
Toro Premium All Season Hydraulic 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, another
conventional petroleum–based fluid may be used provided
it meets the following material properties and industry
specifications. 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.

Industry Specifications:
Vickers I-286-S, Vickers M-2950-S, Denison HF-0, Vickers
35 VQ 25 (Eaton ATS373-C)
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 20 ml (2/3 oz.) bottles. One bottle is
sufficient for 15–22 1 (4–6 gal) of hydraulic oil. Order part
no. 44-2500 from your authorized Toro distributor.
Note: If the oil becomes contaminated, contact your
local Toro distributor because the system must be flushed.
Contaminated oil may look milky or black when compared
to clean oil. The service interval may need to be increased
if using multiple attachments as the oil may become
contaminated quicker with the mixing of different hydraulic
oils.
1. Clean the area around the high flow filter mounting
area (Figure 74). Place a drain pan under the filter and
remove the filter.
Note: If the oil is not going to be drained, disconnect
and plug the hydraulic line going to the filter.
2. Lubricate the new filter sealing gasket and hand turn
the filter onto the filter head until the gasket contacts
the filter head. Then tighten it 3/4 turn further. The
filter should now be sealed.
3. Fill the hydraulic reservoir with approximately 15 l (4
gallons) of hydraulic oil.
4. Start the machine and run it at idle for about two
minutes to circulate the fluid and remove any air
trapped in the system. Stop the machine and recheck
the fluid level.
5. Verify the oil level.
6. Dispose of the oil properly.
Raising the Box in an
Emergency
The box can be raised in an emergency without starting the
engine by cranking starter or by jumping hydraulic system.
Raising the Box using the Starter
Crank the starter while holding the lift lever in the Raise
position. Run the starter for 10 seconds then wait 60 seconds
before engaging the starter again. If the engine will not crank,
you must remove the load and box (attachment) to service
the engine or transaxle.
