2. Baffle
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.

from the tank when the oil filter is removed.
6. Install the replacement hydraulic filter onto the filter
adapter. Do not tighten.
7. Fill the hydraulic tank with hydraulic fluid until the
fluid overflows the filter and then turn the oil filter
clockwise until the rubber gasket contacts the filter
adapter, then tighten the filter an additional 1/2 turn
(Figure 76).
