Optional Equipment Safety Equipment
•
Note the following points when installing optional equipment:
•
Heavy optional equipment requires a larger space to swing. There might be the danger of impacting
other objects if the machine swinging range has not been calculated accurately. A larger space must be
prepared before performing swinging the machine.
•
Never swing, lower or stop your machine suddenly in order to prevent it from tipping over.
•
Never extend or retract the boom cylinder suddenly in order to prevent impact that may cause the
machine to tip.
