Boom Extend and Retract Cables

How to Adjust the Boom
Extend/Retract Cables
Properly adjusted extend/retract cables are
essential to safe machine operation. Failure to
maintain proper adjustment of the cables could
result in unsafe operating conditions and may
cause component damage. The boom extend and
retract functions should operate smoothly and be
free of hesitation, jerking and unusual noise.
1 Start the engine from the ground controls.
2 Raise and extend the boom approximately
15 feet / 3.8 m.
3 Fully retract the boom and lower to the
horizontal position.
4 Stop the engine.
5 Measure the distance between boom tubes
#1 and #2, measuring from the points
identified as (8) and (9). (Illustration 1) This is
dimension "A".
Note: The distance should be approximately 1 in /
2.6 cm. The actual measurement will be a function
of the primary extend/retract cylinder.
