Figure 4-17 Hydraulic Hose Manufacture Date
WARNING
•
Hydraulic hoses and connections must
be inspected by a trained technician
before the first use of the machine, and
at least annually thereafter, for leaks
and/or damage.
•
Leakages and damaged pressure lines
must be immediately repaired or
replaced by an authorized service cen-
ter.
•
Never use your hands to check for sus-
pected hydraulic leaks. Always use a
piece of wood or cardboard.
•
Leaks from hydraulic hoses or pressur-
ized components can be difficult to see,
but pressurized oil can have enough
force to pierce the skin and cause seri-
ous injury.
•
Obtain immediate medical attention if
pressurized oil pierces the skin. Failure
to obtain prompt medical assistance
could result in gangrene or other seri-
ous damage to tissue.
•
Always relieve hydraulic system pres-
sure before performing any mainte-
nance on the machine. Do not tighten
leaking connections when the hydraulic
system is under pressure.
•
Never weld or solder damaged or leak-
ing pressure lines and/or screw connec-
tions. Always replace damaged
hydraulic components.
•
Hydraulic hoses must be replaced every
six years from the date of manufacture,
even if they do not appear damaged.
The date of manufacture (month or quar-
ter and year) is indicated on hydraulic
hoses. See Figure 4-17.
