Hydraulic System Safety
•
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.
•
Seek immediate medical attention if fluid
is injected into skin. Injected fluid must be
surgically removed within a few hours by a
doctor.
Servicing the Hydraulic
System
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.
Position the machine on a level surface.
2.
Disengage the blade-control switch (PTO), move
the motion-control levers to the N
position, and engage the parking brake.
3.
Shut off the engine, remove the key, and wait
for all moving parts to stop before leaving the
operating position.
4.
Allow the engine and the hydraulic system to
cool for 10 minutes.
Note:
The oil level on the dipstick is incorrect
when the oil is checked and the unit is hot.
5.
Move the seat forward.
6.
Clean the area around the dipsticks of
hydraulic-system reservoirs
7.
Remove 1 dipstick from the hydraulic reservoir
(Figure
85).

8.
Wipe the dipstick off and thread the dipstick into
the reservoir.
9.
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 the fluid below the
add mark.
10.
If the oil level is at the add mark, slowly pour
only enough oil into the hydraulic reservoir to
raise the level to the full or H line.
11.
Install the dipstick.
12.
Repeat the procedure for the opposite dipstick.
Either dipstick is used in the machine

2. Add
Replacing the Hydraulic Fluid and
Filters
Service Interval: After the first 250 hours—Change
the hydraulic filters and hydraulic
fluid when using any type of fluid.
Every 250 hours—Change the hydraulic filters
and hydraulic fluid when using Mobil
(more often in dirty or dusty conditions).
