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.
To Extend and Lower the Outriggers
The most common way of extending and retracting the
outriggers is to extend and retract the four outriggers at the
same time. Individual operation is accomplished by selecting
the desired Outrigger/Select Switch.
Extending the outriggers
1. Place the Outrigger/Jack selector switches (1,
Figure 3-27) in the outrigger position—push the top of
the switch.
2. Engage the parking brake.
3. Run the engine at idle speed (accelerator pedal
released).
4. Push the top of the Extend/Retract Switch (2).
5. Press the accelerator pedal to increase the engine
speed, which will accelerate the outward movement of
the outriggers (Figure 3-26). Release the accelerator
pedal and the switch when the outriggers are fully
extended.
Lowering the Jacks
1. Place the Outrigger/Jack selector switches (1,
Figure 3-27) in the jack position—push the bottom of the
switch.
2. Run the engine at idle speed (accelerator pedal
released).
3. Push the top of the Extend/Retract Switch (2).
4. Press the accelerator pedal to increase the engine
speed, which will accelerate the downward movement of
the jacks (Figure 3-28). Release the accelerator pedal
and the switch when the jacks are fully extended.
NOTE: The outriggers can not be extended or retracted
when they are in the lowered position. Attempting
to do this will cause damage to the outriggers.
