1/2 inch / 13 mm before the number 3 boom tube
begins to retract, the boom extend/retract cables
need to be adjusted. Refer to Repair Procedure in

Cables - S-100, S-105, S-120,
S-125, S-100HD, S-120HD, SX-105
XC and SX-125 XC Models
Genie specifications require that this procedure be
performed annually.
Manufacturers specifications require that this
procedure be performed by personnel that are
competent in cable / wire rope inspection.
Note: Additional or more frequent
inspections may be required due to the
following:
• exposed to hostile or corrosive
environmental conditions.
• boom is overloaded
• sustains a shock load
• electrical arcing
• unused for extended periods
The boom extend/retract cables are responsible for
the extension and retraction of the number 3 boom
tube on the S-100, S-105, SX-105 XC and
S-100HD and the number 2 and 3 boom tubes on
the S-120, S-125, S-120HD and SX-125 XC.
Inspecting for foreign objects, damage and/or
improper adjustment of the boom extend/retract
cables on a regular basis is essential to good
machine performance and safe machine operation.
The boom extend and retract functions should
operate smoothly and be free of hesitation, jerking
and unusual noise.
