Pin Removal
When removing pins from boom sections, stand clear of pins
being removed. Even though the boom is resting on
blocking, individual pin connections may still be under the
load. Pins can be ejected forcefully if the boom has any
pressure on it or if the boom is not supported properly.
Disassembly Precaution
Always block boom sections so they are securely supported
and cannot shift or move suddenly when pins are removed. If
there is any doubt about a boom disassembly procedure,
block tightly under boom sections before removing any pin.
DANGER
Collapsing Boom Hazard!
The boom can collapse or jerk when pins are removed. To
avoid death or serious injury:
• Do not remove bottom connecting pins from any
boom section when the boom is supported by straps
(Figure 2-4
, View A).
• Do not remove strap connecting pins until straps are
fully lowered into supports (Figure 2-4
, View C).
• Do not remove bottom connecting pins from any
boom section when the boom point is resting on the
ground and the boom butt is not supported by the
handling cylinder (Figure 2-4
, View B).
• Never work or stand inside the boom unless it is
lowered and securely blocked (Figure 2-4
, View C).
• Do not stand or walk on top of the boom unless it has
walkways.
