Chapter 7 – Prestart Inspection
36 T125J/TB125J – 0192214
Inspect the welds on the structural components. Pay
particular attention to boom welds. The area to be
inspected should be clean and free of dirt and grease.
Look for visible cracks in the weld and at the weld to par-
ent material joint. A bright light may be used to provide
adequate visibility of the inspection area.
Slide Pads
The main boom has slide pads (refer to Figure 7.19)
between the main and tip boom sections.
Figure 7.19 – Slide Pads at Tip End of Boom
Use the lower controls to raise the main boom to hori-
zontal. Extend the tip boom about 1′ (30 cm). Visually
inspect the slide pads to make sure they are in place
and are not obviously loose.
Inspect the surface where the pads contact the interme-
diate and tip booms. The paint must be in place with no
signs of bare metal.
The extension cylinder support bracket has slide pads
that can be inspected by looking into the base end of
the main boom.
Inspect the surface where the pads contact the main
boom. The paint must be in place with no signs of bare
metal.
Wire Ropes
Visually inspect the wire ropes where they are connected
to the outside of the main boom. There are two wire rope
connections on the bottom of the tip end of the main
boom (refer to Figure 7.20) and inside the cover at the
base end of the main boom (refer to Figure 7.21).

5. Pull the level sensor to the side as far as possible
to activate the tilt alarm.
Warning
The potential for an accident increases when safety
devices do not function properly. Death or serious
injury can result from such accidents. Do not alter,
disable or override any safety device.
6. If the alarm does not sound, remove the machine
from service until the problem is corrected.
7. Lower the main boom.
Flashing Light
If the machine is equipped with an optional flashing light,
visually check to see that it flashes. The light should
flash when the engine is running.
Sandblast Protection Kit
The optional sandblast protection kit protects the cyl-
inders from abrasion while sandblasting or from paint
overspray. Rubber covers protect each cylinder rod as
it extends and retracts. The covers prevent sand and
paint from damaging the cylinder seals and rod.
Inspect the covers while operating the machine to en-
sure they are securely fastened and completely cover
the cylinder rod. Make sure there are no holes in the
covers.
Structures
Visually inspect all weldments and related components.
It is important to inspect the fasteners that connect the
components.
Weldments
Visually inspect all weldments for abnormal wear,
abrasion or deformation that could cause interference
between moving parts.
