12. To check the angle preset warning at a high boom angle. Set the high angle preset warning
to 70 degrees. Boom up until the light and horn come on. This must occur between 68 and
70 degrees. If the warning occurs too early or too late, adjust pot R21 3.4 V. Ref in the
panel until it is correct.
Set the high preset knob to maximum.
13. To check the low angle preset warning at a high boom angle. Boom up above 70 degrees.
Set the low angle preset warning to 70 degrees. Boom down until the light and horn come
on. This must occur between 70 and 72 degrees. If the warning occurs too early or too
late, adjust R21 3.4 V. Ref in the panel until it is correct.
If this is an HAP system continue at step 17.
14. Check and adjust the length indication (HLAP ONLY). Push the L button to select length
indication. The length should read the fully retracted boom length. If it does not, adjust
pot R16 (L) Offset in the panel until it is correct.
15. Fully extend the boom (including any manual or pinned section). Check the length indication
against the actual boom length. If it is incorrect, adjust pot R12 (L) Max in the panel until
the correct length is indicated.
16. Fully retract the boom and check the length indication. If necessary re-adjust pot R16 (L)
Offset in the panel. Calibration of the retracted and extended boom lengths interact,
which may make it necessary to repeat these steps for proper length indication.
17. Complete installation of Crane function shut off system, if required.
18. Create a Two-Block condition by lifting the counterweight at the boom head. Check that
the light and horn come on. If equipped with a Crane function shut off system the following
functions should be dis-abled.
Boom Hoist - Down
Boom Telescope - Out
Main Winch / Front or Right hand Drum - Up
Aux. Winch / Rear or Left hand Drum - UP
19. Lower the counterweight to verify that the light and horn go off and all crane functions
return to normal operation.
18. The machine is ready for operation.
