WARNING
MANUAL OPERATION OF CRANE. WITH THE CRANE IN THE MANUAL
OVERRIDE CONDITION THE OVERLOAD SAFETY SYSTEM IS INOPERATIVE,
SHOULD THE CRANE BE INADVERTENTLY OVERLOADED CATASTROPHIC
FAILURE OF THE CRANE MAY OCCUR. DEATH OR SEVERE INJURY COULD
RESULT IF THIS INSTRUCTION IS NOT HEEDED.
If crane will not deploy normally operate the crane manual override lever at
crane operating lever console. Operate crane with great care.
29. Position and unstrap flatrack V1 and T1 on build site.
30. Check and level A-frame using A-frame stabilizer legs.
Ensure A-frame stabilizer leg pin is NOT inserted through the transportation
hole.
Check that A-frame pin is correctly positioned in the stabilizer leg and the A-
frame is sat on the pin.
Check A-frame stabilizer leg cylinder mounting points to ensure pins are in
place and secure.
Check for significant distortion of A-frame leg and stabilizer for damage.
Report any distortion/damage to maintenance.
31. Set beam angle.
Is BEAM ANGLE selected on the chest pack?
Has the chest pack right hand joystick been moved rearward to lower the far
bank support?
Check for any signs of twisting at the launch frame to A-frame upper
transverse beam, this would indicate a seizure of the center pivot bushing.
Report any signs of seizure to maintenance.
32. Remove launch beam final stop.
Remove R clip from launch beam final stop pin.
Is the pinch roller ball valve closed (located on the Launch Frame Pinch
Roller Stowing Manifold)? If NO, close pinch roller ball valve.
