1.
Position the crane on a firm, level surface.
2.
Extend and set the outriggers. Level the crane, as
indicated by the bubble 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 bubble level indicator mounting screws, adjust
the bubble level indicator to show level.
Site Selection
The outrigger floats must be on a firm solid surface that is
level. The surface must keep the crane stable and not allow
the stabilizer float to sink or slide. Avoid areas that are:
•
uneven
•
rocky
•
muddy
Setting the Outriggers and Stabilizers
The outrigger setup procedure is as follows:
NOTE:
All outriggers must be extended fully to a firm
surface. Use the outriggers as necessary to level
the truck side-to-side, then stabilizers to level the
truck front-to-back. A level indicator is provided at
the operator’s station. A signal person must be
used to be sure the outriggers are set safely.
1.
Use the outrigger and stabilizer control levers
(Figure 3-1).
2.
Extend both outriggers and both stabilizers until the
truck tires are about four inches off the ground.
3.
Adjust the outriggers until the bubble in the level
indicator is in the center of the bulls eye and the
Outrigger Status Indicator (if equipped) illuminates
constant green. Do not allow the tires to touch the
ground.
4.
Using the level indicator, adjust the stabilizers until the
bubble is in the center of the bulls eye. Do not allow the
tires to touch the ground. Ensure Outrigger Status
Indicator (if equipped) illuminates constant green before
making a lift. If it is suspected that the bubble level
indicator is out of adjustment, verify and adjust the
bubble level using the procedures under
5.
Lower the single front outrigger (SFO) (optional) only
after all other outriggers and stabilizers are set. Press
the SFO switch to activate and the extend/retract switch
to extend. Hold the extend/retract switch for two
seconds after the SFO contacts the ground. The SFO is
automatically set at the correct ground pressure.
6.
Verify that the RCL has preselected the outrigger
position mode correctly.
Lifting Over the Rear
Before conducting any boom operations, extend both
outriggers until the chassis weight is removed from the
wheels. Level the crane from side-to-side. A level indicator is
provided at either control station. Then extend and lower the
stabilizers to level the crane front-to-back. Again refer to the
level indicator to insure that the crane is properly leveled.
Always keep the load as close to the ground as possible.
