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.

System
Hydraulic Fluid Type: Toro

hydraulic fluid level.
1. Position the machine on a level surface.
2. Move the speed-control lever to the N
position to stop the machine.
3. Disengage the PTO, engage the parking brake,
shut off the engine, and wait for all moving parts
to stop.

cool for 10 minutes.

pour only enough oil into the hydraulic reservoir
to raise the level to the full line.
Important:
Do not overfill the hydraulic
units with oil, as damage may occur. Do not
run the machine with the oil below the add
mark.

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 or gangrene
may result.
• Keep your 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 that all hydraulic fluid
hoses and lines are in good condition
and all hydraulic connections and
fittings are tight before applying
pressure to hydraulic system.
