Checking The Hydraulic Lines And Hoses; Checking The Leak Detector - Toro Greensmaster 04358 Operator's Manual

Checking the Hydraulic
Lines and Hoses
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
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.
• Get immediate medical help if fluid is
injected into skin.
Check 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.

Checking the Leak Detector

The leak detector system is designed to assist in early
detection of hydraulic-fluid-system leaks. If the fluid
level in the main hydraulic reservoir is lowered by
118 to 177 ml (4 to 6 oz), the float switch in the tank
will close. After a 1 second delay, the alarm sounds,
alerting the operator (Figure
due to normal heating during machine operation,
causes the fluid to transfer into the auxiliary fluid
reservoir. The fluid returns to the main tank when you
turn off the ignition switch.
