Operating the boom
•
To raise the boom, pull the right control lever ( ) back.
The hydraulic cylinder of the boom is equipped with
a cushioning function, which prevents the
excavated material in the bucket from falling out.
When the hydraulic system operating temperature
is low, the cushioning is delayed for approx. 3 to 5
s. This delay is due to the viscosity of the hydraulic
oil and is not a malfunction.
