7. ADJUSTING EMPTY HOOK LOAD DISPLAY
Problem:
Load displays (hook display) incorrect with no load on hook.
Retract or extend the boom to the length step with the problem.
-Actual boom length must agree with the length step (LS) on the hand terminal display-.
Boom down from high boom angle to low boom angle and observe the load (=hook) display. Since
you boom down without load, the load displayed should be around 0 LB. Now position the
boom at approximate 45 degree boom angle and lower the hook from the boom nose down
to ground. Observe the load display on the hand terminal.
Connect the hand terminal as described in section 2.2.
Select the on-line mode as described in section 3.4.
