makes the total weight for the load handling devices 286 kg
(632 lb).
A check of the load chart for a 15.2 m (50 ft) radius and
19.5 m (64 ft) of boom length shows a capacity of 3601 kg
(7940 lb) on outriggers over-front and 4970 lb on outriggers
360 degrees. We subtract the load handling weight of 632 lb
from the load capacity of 3601 kg (7940 lb) and 2254 kg
(4970 lb). The result is a weight capacity of 3315 kg
(7308 lb) over-the-front and 1968 kg (4338 lb) for 360
degrees. We are constricted in making the lift over-front only
and the boom angle will be about 29 degrees.
Proper Leveling of the Crane
ASME B30.5 specifies that if a crane is not level within 1% of
grade, the allowable capacities must be reduced. Therefore,
whether lifting on rubber or outriggers, it is essential that the
crane is level to within 1% of grade. The bubble level
indicator that is provided on the crane is calibrated to be
accurate within 1% of grade.
To properly level the crane, the boom must be positioned
over the front of the crane, fully lowered to horizontal and
fully retracted (for cranes fitted with a boom rest, the boom
shall be stowed onto the rest). Raise and level the crane
using the outriggers; refer to Setting the Outriggers, page 3-
20.
A working crane may settle during lifting operations.
Frequently check the crane for level. When rechecking the
crane for level, the boom must be positioned over the front of
the crane, fully lowered to horizontal and fully retracted (for
cranes fitted with a boom rest, the boom shall be stowed
onto the rest). If necessary, relevel the crane using the
procedures under Setting the Outriggers, page 3-20.
Level Indicator Adjustment
The Level Indicator should be checked periodically; if it is
suspected that the Level Indicator is out of adjustment, verify
and adjust the level as follows:
1. Position the crane on a firm, level surface.
2. Extend and set the outriggers. Level the crane, as
indicated by the level indicator, using the outriggers.
3. Place a miracle pointer level, carpenter level, or similar
type device on a machined surface such as the turntable
bearing or bearing mounting surfaces.
4. Using the outriggers, level the crane as indicated on the
leveling device used in step 3.
5. Using the level indicator mounting screws, adjust the
level indicator to show level.

Crane Functions
Using the Outriggers
The outriggers are operated from the front console in the cab
or by using the jog dial on the armrest.
To prevent serious injury or death, keep clear of moving
outrigger beams/jacks.
Death or serious injury could result from improper crane
setup on outriggers.
Be sure the outriggers are properly extended and set, and
the crane is level for operation on outriggers.
All four outrigger beams must be equally extended to the
mid position vertical stripe or fully extended position
before beginning operation.
When operating the crane on outriggers, the outriggers
should always be fully extended or locked in the mid-
extend position.
NOTE:
Setting the Outriggers
1. Engage the Parking Brake.
NOTE:
2. Position the outrigger floats directly out from each
outrigger to where the outriggers will be properly
extended.

WARNING
WARNING
The crane also allows operations with the
outriggers fully retracted.
To enable outrigger functions: The crane must be in
four wheel drive, the parking brake must be
engaged, the swing brake must be engaged, and
all crane functions must be off.
