4. 2-stage boom pushing force selector function
Outline
• This function switches the pushing force of the
boom. It is aimed to provide both increased dig-
ging efficiency by reducing the digging resist-
ance of the boom, and increased ease of
operation by increasing the thrusting force for ex-
cavation, digging square holes, carrying out twist
turns, or escaping from soft ground.
