Check each of the six boom-movement switches
(2) using GROUND OPERATION (3) to see that
they cause the TB126J to move the way it
should. Check both positions of each switch. (For
correct operating procedures see the
“OPERATION” chapter.)
4
Check all of the boom-movement, drive, and
steering functions from the platform-control box
(4) to see that they cause the TB126J to move
the way it should. (For correct operating
procedures see the “OPERATION” chapter.)
NOTE: Leave the engine running for the next
step.
20. Slide pads
With the engine running, use the ground-control
box to extend the booms about 10 feet (three
metes). Visually inspect to see that all the slide
pads are in place in the rear ends of the booms:
seven slide pads (1) in the base boom, six (2) in
the inner-intermediate boom, and six (3) in the
outer-intermediate boom.
Look at the surface (4) that slides on each slide
pad. The paint should still be in place and there
should not be any signs of bare metal gouging.
Check the slide pads and paint inside the front
end (5) of the base boom similarly.
Completely retract the booms then turn the
engine OFF at the ground-control box MASTER
KEY SWITCH.
21. Whiffles and wire ropes
While you are inspecting the whiffles check the
condition of the wire ropes near the whiffles. The
wire ropes should not have any broken strands
or be distorted in any way.
Visually inspect the whiffle (1) at the rear end of
the base boom (2). The face of the whiffle (1)
should be parallel to the end of the base boom
(2). Visually check the stack of spring washers
(3) on the end of each wire rope (4). The
washers (3) should be squashed tightly
together...
