Checking the Hydraulic Lines
After every 100 operating hours, check hydraulic lines and
hoses for leaks, loose fittings, kinked lines, loose
mounting supports, wear, weather and chemical
deterioration. Make necessary repairs before operating.
Note: Keep areas around hydraulic system clean from
grass and debris build up.
Warning
Hydraulic fluid escaping under pressure can
penetrate skin and cause injury.
If hydraulic fluid is injected into the skin it
must be surgically removed within a few hours
by a doctor familiar with this type of injury.
Gangrene may result if this is not done.
Keep 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.
Make sure all hydraulic fluid hoses and lines
are in good condition and all hydraulic
connections and fittings are tight before
applying pressure to hydraulic system.
