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.

to Checking the Hydraulic Fluid in Operation,
page 18) and add fluid to raise the level to mark
on dipstick. Do not over fill the tank.
