Checking The Hydraulic Fluid - Toro ProLine 30526 Operator's Manual

Checking the Hydraulic Fluid

Check the hydraulic fluid level before engine is first
started.
Check the hydraulic fluid level after first 8 operating hours.
Check the hydraulic fluid level after every 25 operating
hours.
Fluid Type: Mobil 1 15W-50 synthetic motor oil or
equivalent synthetic oil.
Important Use oil specified or equivalent. Other fluids
could cause system damage.
Hydraulic System Oil Capacity: 77 oz. (2.3 l)
Note: There are two ways of checking the hydraulic oil.
One is when the oil is warm and one is when the oil is cold.
The baffle inside the tank has two levels depending if the
oil is warm or cold.
1. Position machine on a level surface.
2. Disengage the PTO, turn the ignition key to off, and
remove the key.
3. Wait for all moving parts to stop before leaving the
operating position and then chock or block tires.
4. Clean area around cap and filler neck of hydraulic tank
(Fig. 16).

5. Remove cap from filler neck. Look inside to check if
there is fluid in the reservoir. (Fig. 16).
6. If there is no fluid, add fluid to the reservoir until it
reaches the cold level of the baffle.
7. Run the machine at low idle for 15 minutes to allow any
air to purge out of the system and warm fluid. Refer to
Starting and Stopping the Engine on page 20.
8. Recheck the fluid level while the fluid is warm. If
required, add fluid to the reservoir until it reaches the
hot level of the baffle.

Note: The fluid level should be to the top of the hot level
of the baffle, when the fluid is warm (Fig. 16).
9. Install cap on filler neck.
Warning
Hydraulic fluid escaping under pressure can
penetrate skin and cause injury.
If hydraulic fluid is injected into the skin it must
be surgically removed within a few hours by a
doctor familiar with this type of injury.
Gangrene may result if this is not done.
Keep body and hands away from pin hole leaks
or nozzles that eject high pressure hydraulic
fluid.
Use cardboard or paper to find hydraulic leaks.
Safely relieve all pressure in the hydraulic
system before performing any work on the
hydraulic system.
Make sure all hydraulic fluid hoses and lines are
in good condition and all hydraulic connections
and fittings are tight before applying pressure to
hydraulic system.
