Checking hydraulic hoses for damage and aging
Important information for the owner of the machine
Observe the maintenance intervals
– see "Maintenance plan" on page 7-6.
The entrepreneur/owner of the machine must ensure that hose pipes are
replaced in appropriate intervals, even if no safety-relevant malfunctions
can been detected on the hose pipe.
• Have hose pipes checked by an authorized service center at least
once a year to ensure a safe working condition.
• Leaks and damaged pressure lines must be immediately repaired or
replaced by an authorized service center.
• Have hydraulic hoses replaced by an authorized service center
every 6 years from the date of manufacture, even if
they do not seem to be damaged.
The date of manufacture (month or quarter and year)
is indicated on the hose pipe.
Example: The indication “2 Q/18” means manufactured in the 2nd
quarter of 2018.
In the Federal Republic of Germany, reference is made in this connection
to the “Safety regulations for hydraulic lines” issued by the Central Office
for Accident Prevention and Occupational Medicine. Reference is also
made to DIN 20066, part 5.
