DEMOLITION DIGGING BOOM INSTALLATION AND REMOVAL
15. Operate the "Attachment Rotate" function. Left Hand (LH)
button makes the pins retract, Right Hand (RH) button makes

Check that the pins are fully retracted before moving the
machine.
Never use ANY other control to cause the hydraulic pins to
move. This could cause injury, damage or death.

ground. When Stand B is settled onto the ground, simulta-
neously lower the first boom section and reverse the machine
to disengage the upper pin from the demolition equipment.

ment, make sure that all operators are standing well clear of
the machine and equipment.
