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 Figure 93.
