Maintenance 7
Checking hydraulic hoses for damage and ageing
Important information for the owner of the machine
Observe the maintenance intervals – see “Maintenance plan” on
page 7-3.
The entrepreneur/owner of the machine must ensure that flexible lines are
replaced in appropriate intervals, even if no safety-relevant malfunctions
can been detected on the flexible line.
• Have hose pipes checked by an authorized service center at least
once a year to ensure a safe working condition.
• Leaking and damaged pressure lines must be immediately repaired or
replaced by an authorized service centre.
• 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 flexible line.
Reading example: The indication "1 Q/16" means manufactured in the
1st quarter of 2016.
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.
