for the procedure to release the
hydraulic pressure.
WARNING
Risk of high pressure injection.
Residual pressure in the hydraulic system could
lead to oil under high pressure jetting out and cause
serious injury, even if the engine has not been
running for some time.
Always release the pressure before any kind of
service of the hydraulic system is carried out.
CAUTION
Risk of cutting and crushing.
Loose parts could cause crushing and cutting injury.
Never use your fingers for checking alignment
between loose parts. Always use a tool.
NOTE!
The linkage could change position during changing
attachment, pay attention on moving parts.
