Checking the Hydraulic Lines
and Hoses
Service Interval: Before each use or daily—Check the
hydraulic lines and hoses for leaks, kinked
lines, loose mounting supports, wear,
loose fittings, weather deterioration, and
chemical deterioration.
WARNING
Hydraulic fluid escaping under pressure can
penetrate skin and cause injury.
• 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 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.
Using the 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.
