General instructions
Hydraulic hose
Warning
Be sure to depressurize the hydraulic system
before maintaining or repairing it.
Stop the engine, and lower the rake.
When checking for pinhole leakage of the
hydraulic circuit or oil leakage of the nozzle,
search for a leakage point using something
like paper or cardboard, never with your bare
hands. Be careful about high-pressure oil
which may pierce your skin, resulting in
physical injury.
Hydraulic hoses are subjected to excessive
load when weathered, exposed to the sun or
chemicals, stored in a very hot storage
environment, or handled roughly during
operation or maintenance work. These factors
may cause damage to hoses or facilitate their
deterioration. Since a hydraulic hose is more
sensitive to external conditions than other
components, check it frequently for damage,
deterioration or the like of.
When replacing the hydraulic hose, check that
the hose is straight (not twisted before fitting).
When replacing the hydraulic hose, use two
spanners. First, support the hose at a
designated point with the first spanner. Next,
fasten the hose swing nut to the fitting with the
second spanner.
