in the system.
CAUTION: Avoid damaging
hydraulic hose. Avoid sharp
bends and kinks when routing
hydraulic hoses. Using a bent or kinked
hose will cause severe back-pressure.
Sharp bends and kinks will internally
damage the hose leading to premature
hose failure.
Do not drop heavy objects
on hose. A sharp impact may
cause internal damage to
hose wire strands. Applying pressure to
a damaged hose may cause it to
rupture.

heat will soften packings and seals,
resulting in fluid leaks. Heat also
weakens hose materials and packings.
