The distance between the hook block and the boom nose
changes during telescoping. Ensure that the hook block
does not trigger the anti-two block switch or touch the
ground.
• To prevent two-blocking or slack rope conditions,
perform the following functions as required:
- Lower hoist when extending
- Lift hoist when retracting.
The control lever movements for telescoping vary depending
on the configuration.
With telescoping assigned to the right-hand lever
Push the control lever to the right

Figure 4-119) or right arrow for extending (2) is shown in the
indicated location of the operating display screen (either the
semi-automation or manual telescoping screen).
