HYDRAULIC LINESAND HOSES
All the hoses, lines and fittings must be checked regularly. It is better to check before start, to
check monthly, to check annually for leaks and any externally visible damage! Any damaged
sections must be replaced immediately! Escaping oil can cause injuries and fires!
Even if hoses and lines are stored and used properly, they undergo a natural aging process.
For that reason, their service life is limited.
Improper storage, mechanical damage and improper use are the most frequent causes of hose
failures.
The service life of a hose may not exceed six years, including a storage period of not more
than two years (always check the manufacturer’s date on the hoses).
Using hoses and lines close to the limit ranges of permitted use can shorten the service life
(for example at high temperatures, frequent working cycles, etc).
Hoses and lines must be replaced if any of the following points are found during an
https://tractormanualz.com

13
inspection:
-- Damage on the external layer into the inner layer (such as chaffing, cuts and rips)
-- Brittleness of the outer layer and
-- Changes in shape.
-- Corrosion on fittings, Crack, wear and squeeze.
-- Storage or service life has been exceeded.
When replacing hoses or lines, always use the original parts of Shandong Kadekor Power
Machine Co.,Ltd.
