minutes to purge air from the system. Stop the
engine and check for leaks.
CHECKING HYDRAULIC LINES
AND HOSES
Daily, check hydraulic lines and hoses for leaks,
kinked lines, loose mounting supports, wear, loose
fittings, weather deterioration and chemical
deterioration. Make all necessary repairs before
operating.
WARNING
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. Hydraulic fluid escaping under pressure can
penetrate skin and cause injury. Fluid accidentally
injected into the skin must be surgically removed
within a few hours by a doctor familiar with this
form of injury or gangrene may result.
HYDRAULIC SYSTEM TEST
PORTS
The test ports are used to test pressure in the
hydraulic circuits. Contact your local Toro
distributor for assistance.

other parts of the body away from the muffler,
other hot parts or the engine, and other rotating
parts.
