Safety
Avoid traveling with a suspended load. Before swinging (or if
required, traveling), bring the load into an arm position (radius
and height) that has a safer weight capacity rating and adequate
movement clearance. The operator and all work site personnel
should be thoroughly familiar with safety instructions and
procedures within this Operation and Maintenance Manual.
The following weight loads are in compliance with SAE (J1097)
and ISO applicable, recommended standards for hydraulic
excavators performing lifting operation on a firm supporting
surface. An asterisk (*) next to the lift rating indicates rated load
does not exceed 87% of hydraulic capacity. All other ratings
have been determined not to exceed 75% of tipping capacity.
Do not attempt to lift or hold any load that exceeds rated load
capacity at the specified distances (from the machine's rotation
center line and height - see "lift radius" and "lift height" in the
reference drawing, Figure 49).
The weight of slings and any auxiliary lifting device (and/or the
weight difference of any attachment heavier than standard
configuration) must be deducted from the rated lift capacity to
determine allowable net lifting load. The lift point should be on
the back of the bucket, as shown in Figure 49.

IMPORTANT
Select the Digging Mode switch on the Instrument Panel
before using the excavator for lifting work. Engine and
hydraulic oil should both be fully warmed up to operating
temperature before starting a lift.
