SX-135 XC models:
Note: Properly adjusted extend/retract cables will
maintain a relationship of the gap between boom
tubes #2 and #3.

2 Fully raise the boom then extend the boom
approximately 15 ft / 4.6 m.
3 Fully retract the boom and lower to the
horizontal position.
4 Stop the engine.
5 Measure and record the distance between
boom tubes #1 and #2, measuring from the
points identified as (4) and (5) in the
illustration. This is dimension "A".

2 Boom tube #2
3 Boom tube #3
4 Boom #1 measuring surface

6 Measure the distance between boom tubes #2
and #3 using points (6) and (7) in the
illustration. The gap should be
1 in / 2.6 cm to 1.5 in /3.9 cm greater than
dimension "A".
Note: As an example, if the dimension "A" is 1.25 in
/ 3.2 cm, then the gap between boom tubes #2 and
#3 should be between 2.25 in / 5.7 cm and 2.75 in /
7.1 cm.
Result: The distance between boom tubes #2
and #3 is 1 in / 2.6 cm to 1.5 in /3.9 cm greater
than dimension A. The boom tube is in
tolerance.
Result: The distance between boom tubes #2
and #3 is less then 1 in / 2.6 cm or more than
1.5 in / 3.8 cm greater than dimension "A". The
boom tubes need to be adjusted. Refer to
