6. Install the filter by hand until the gasket contacts the
mounting surface, then rotate it an additional 1/2 turn.
7. Start the engine and let it run for about two minutes to
purge air from the system.
8. Stop the engine and check for leaks.
Checking the Hydraulic Lines

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.
• Get immediate medical help if fluid is injected
into skin.
Hydraulic System Test Ports
Use the hydraulic system test ports to test the pressure in
the hydraulic circuits. Contact your local Toro distributor for
assistance.
Use the test ports on the front hydraulic tubes
assist in troubleshooting the traction circuit.
