Hydraulic fluid escaping under pressure
can penetrate skin and cause injury.
Fluid 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.
• 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, never use your hands.
10. Check the fluid level in the hydraulic tank (refer
to Checking the Hydraulic Fluid in Operation,
page 17) and add fluid to raise the level to mark
on dipstick. Do not over fill the tank.
11. Remove and store the cylinder locks and lower
the loader arms.
