JIB SAFETY INFORMATION
1. The anti-two-block (A2B) switch weight and cord must
be attached to the jib when deployed.
2. Operate with jib by radius when main boom is fully
extended. If necessary, increase boom angle to maintain
loaded radius.
When radius is between points listed on capacity chart,
the load shown at the next longer radius shall be used.
3. Operate with jib by boom angle when main boom is not
fully extended. Do not exceed rated jib capacities at any
reduced boom lengths.
When angle is between points listed on capacity chart,
the load shown at next lower boom angle shall be used.
4. Ensure jib is stowed correctly (Figure 6-1):
a. Removal of swing around pins (C1, Figure 6-1),
without proper installation of stow pin A and jib
swing pin B, may allow jib to fall off.
b. Extending boom with jib stowed and failure to
remove swing pins (C1, Figure 6-1), will damage
unit upon extension.
5. Only swing jib into working or stowed position when
boom is horizontal, stow pin (A, Figure 6-1) and jib swing
DANGER
Do not operate outriggers unless they are visible to either
the operator or a designated signal person to avoid
crushing injury.
