To begin setup for testing the upper boom,
install jumpers between components in the
following locations as shown in
•
Turntable above rotation to pedestal below
rotation (#1)
•
Turntable above rotation to lower boom (#2)
•
Lower boom insert (#3)
•
Upper boom to knuckle (#4)
•
Knuckle to lower boom (#5)
•
Platform bracket to boom tip bracket (#6)
•
Jib bracket (if equipped) to platform bracket
(#7)
Verify that the jumpers make good contact by
removing paint, if needed, at the attachment
location prior to attaching the jumpers. Some
units are equipped with stainless bolts
specifically for dielectric testing, use these if
equipped.
The jumpers and connections are shown in RED
in the following Figures. They do not reflect the
actual connection points where the jumpers are
installed on the unit, but are only a reference to
the general location.
