Hydraulic System Test Ports - Toro 03806 Operator's Manual

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.
