Important: Use only the hydraulic fluids
specified. Other fluids could cause system
damage.
8. Install the reservoir cap. Start the engine and use all
of the hydraulic controls to distribute hydraulic fluid
throughout the system. Also check for leaks; then
stop the engine.
9. Check the fluid level and add enough to raise level
the level to the Full mark on the dipstick. Do not
overfill.
Checking the Hydraulic Lines
and Hoses
Service Interval: Every 2 years—Replace moving
hoses.
Inspect the hydraulic lines and hoses daily for
leaks, kinked lines, loose mounting supports, wear,
loose fittings, weather deterioration, and chemical
deterioration. Make all necessary repairs before
operating.
WARNING
Hydraulic fluid escaping under pressure can
penetrate skin and cause injury.
• Make sure 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 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.
• Seek immediate medical attention if fluid is
injected into skin.

Hydraulic System Test Ports

The test ports are used to test the pressure in the
hydraulic circuits. Contact your local Toro distributor or
refer to the Toro Service Manual for assistance.
