To set the Radius;
Fully retract the boom, and lower boom to zero degrees
, look at the display to see what
the radius indication is. Using a flat tip screw driver turn the screw on the length pot
assembly until the radius indication on the display is correct. Now extend the boom fully
and check it, then retract it again to see if it is ok. Continue this procedure until the
radius indication is correct. MS1/L1 should be approxi0.250vdc (range +
0.248vdc to 0.251vdc).
