Hydraulic System Safety
•
Seek immediate medical attention if fluid is injected
into skin. Injected fluid must be surgically removed
within a few hours by a doctor.
•
Ensure that all hydraulic-fluid hoses and lines are
in good condition and all hydraulic connections
and fittings are tight before applying pressure to
the hydraulic system.
•
Keep your body and hands away from pinhole
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.
Servicing the Hydraulic
System
Hydraulic-Fluid Specifications
Hydraulic-Fluid Type: Toro
hydraulic fluid or Mobil
Important:
Use the specified fluid. Other fluids
could damage the hydraulic system.
Each Hydraulic-System Fluid Capacity: 1.5 L (52
oz) per side with filter change
Checking the Hydraulic Fluid
Service Interval: Every 50 hours—Check the
hydraulic-fluid level.
1.
Park the machine on a level surface, disengage
the blade-control switch (PTO), and engage the
parking brake.
2.
Shut off the engine, remove the key, and wait
for all moving parts to stop before leaving the
operating position.
3.
Allow the engine and the hydraulic system to
cool for 10 minutes.
Note:
The fluid level on the dipstick is incorrect
when the fluid is checked and the machine is hot.
4.
Move the seat forward.
5.
Clean the area around the dipsticks of
hydraulic-system reservoirs

6.
Remove 1 dipstick from the hydraulic reservoir
(Figure

7.
Wipe the dipstick off and thread the dipstick into
the reservoir.
8.
Remove the dipstick and look at the end

Important:
Do not overfill the hydraulic
units with fluid, as damage may occur. Do
not run the machine with fluid below the add
mark.
9.
If the fluid level is at the add mark, slowly pour
only enough fluid into the hydraulic reservoir to
raise the level to the full or H line.
10.
Install the dipstick.
11.
Repeat the procedure for the opposite dipstick.
Either dipstick is used in the machine
