4.3-4 Grab operation
Grabs should be used exclusively for moving loose materials such as sand, gravel, soil etc. Never use
the grab for removing or pulling objects (masts, trees etc.), pushing or hitting, because this can
damage the crane and the grab. Installation of grab and rotator see operating instructions for the
grab.
For grab operation your crane should be equipped with an adequately sized tank or with an oil cooler
(oil temperature), but the oil temperature should still be checked continually during grab operation.
