Plumbing Installation (Figure
7.)
Keep hands and body from pressurized lines. Use
paper
or
cardboard, not body parts, to check for
leaks.
Hydraulic oil under
pressure will penetrate the skin causing
serious injury.
Make sure that all operating and service
personnel know that
In the event hydraulic fluid
penetrates skin,
It
must be surgically removed
within a few hours by a doctor familiar with this
form of injury, or gangrene may result.
To prevent damage to the
hydraulic system:
Clean all fittings and use care to prevent
foreign
material from entering hydraulic
system.
Additional sealant such as pipe dope or
Teflon thread tape is not required on O
-
ring
fittings.
Teflon thread tape
Is
recommended for pipe
threads. Use care when applying to prevent
excess tape from entering hydraulic
system.
Make sure all hydraulic connections are
tight and all hydraulic
lines
and hoses are
In
good condition before engaging the
tractor PTO.
