OPERATING TIPS
• The control levers should be moved in a gradual, deliberate way rather than with jerky, abrupt movements. Jerky
movements will provide a rough ride in the cab and could give the appearance of instability.
• Avoid handling long, heavy materials o center. Excessive weight held out to one side can force the attachment to
rotate or “Back-drive”. Back-driving puts increased strain on the rotation system and, if done continually, can lead to
rotation component problems. The rotator is for positioning only.
• Do not apply excavator force or weight at either end of the upper shear in an attempt to un-jam the shear or to cut
materials that are too large.
• Avoid handling long, heavy materials o center.
