Hydraulic Hose Maintenance
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 hose/lines
must be immediately repaired or replaced by an
authorized service center.
Never use your hands to check for suspected
hydraulic leaks. Always use a piece of wood or
cardboard.
Leaks from hydraulic hoses or pressurized
components can be difficult to see, but
pressurized oil can have enough force to pierce
the skin and cause serious injury.
Obtain immediate medical attention if
pressurized oil pierces the skin. Failure to
obtain prompt medical assistance could result
in gangrene or other serious damage to tissue.
Always relieve hydraulic system pressure
before performing any maintenance on the
machine. Do not tighten leaking connections
when the hydraulic system is under pressure.
Never weld or solder damaged or leaking
pressure lines and/or screw connections.
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 quarter and year) is
indicated on hydraulic hoses. See Fig. 147.
