Sandblast Protection Kit
The optional sandblast protection kit protects the cylin-
ders from abrasion while sandblasting or from paint
overspray. Rubber covers protect each cylinder rod as
it extends and retracts (refer to Figure 7.15). The cov-
ers prevent sand and paint from damaging the cylinder
seals and rod.
Figure 7.15 – Sandblast Protection
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, abra-
sion, or deformation that could cause interference be-
tween moving parts.
Inspect the welds on the structural components. Pay
particular attention to boom welds. The area to be in-
spected should be clean and free of dirt and grease.
Look for visible cracks in the weld and at the weld to
parent material joint. A bright light may be used to pro-
vide adequate visibility of the inspection area.
Slide Pads
The main boom has slide pads between it and the tip
boom.
Use the lower controls to raise the main boom to hori-
zontal. Extend the tip boom about 30 cm (1 ′). Visually
inspect the slide pads (refer to Figure 7.16) to make
sure they are in place and are not obviously loose.

5. Pull the level sensor to the side as far as possible to
activate the tilt alarm.
A
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 optional flashing lights,
visually check to see that they flash. There is one light
on each side of the machine (refer to Figure 7.14). The
lights should flash when the engine is running.
