10. DAILY INSPECTION & MAINTENANCE
10 - 10 P/N 0191914
26. Platform work lights (option)
While the engine is running, momentarily turn
each work light on (use the switch on the back
of each light) to see that they both work.
27. Flashing lights (option)
Visually check to see that the lights flash at
approximately one flash per second when the
engine is running. (See the “OPTIONS” chapter
for a photograph of the lights.)
28. Driving lights (option)
While the engine is running, momentarily turn
the driving lights on to see that they work. (See
the “OPTIONS” chapter for a photograph of the
lights.)
29. Slide pads
Start the TB120 engine. Raise the platform
about three feet (1 m) then extend the main
boom as far as it will go (about six feet or 2 m)
with the rear axles retracted. 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.
30. 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...
...there should not be any gaps between the
washers as shown here.
