• The hydraulic drift of the work equipment (the amount of the work equipment moves down under its
own weight when it is stopped in a raised position) also becomes greater. Do not stop the work
equipment in air.
• Do not suddenly swing, lower, or stop the work equipment. It is dangerous that the machine may tip
over.
• Do not suddenly extend or retract the boom cylinder rod. The shocks may cause the machine to tip
over.

WARNING
NOTE: When calculating the allowable mass of attachments, the mass of the bucket, see the following “EX-
PLANATION OF LIFT CAPACITY CHART (6.7M BOOM) (5-4)”,“EXPLANATION OF LIFT CAPACITY CHART
(7.1M BOOM) (5-7)” should be taken into consideration.
For an attachment not intended to bear a load, for example a breaker, it should not exceed the
minimum
lift
capacity of the machine as shown on the related lift capacity charts (see SPECIFICATIONS section Chapter 5).
For attachments intended to bear a load, for example clamshell bucket or grapple, the combined mass of the
attachment plus load, should not exceed the
maximum
lift capacity figures as shown in the related lift capacity
charts (see SPECIFICATIONS section Chapter 5).
