Structures
Visually inspect all weldments and related components.
It is important to inspect the fasteners that connect the
components.
Weldments
To inspect the weldments:
1. Visually inspect all weldments for abnormal wear,
abrasion, or deformation that could cause interfer-
ence between moving parts.
2. Inspect the welds on the structural components. The
area to be inspected should be clean and free of dirt
and grease.
3. Look for visible cracks in the welds and at the weld
to parent material joints. A bright light may be used
to provide adequate visibility of the inspection area.
4. Pay close attention to welds in areas where changes
in cross section take place and near the attachment
points of highly loaded components.
Slide Blocks
To inspect the slide blocks:
1. Visually inspect the scissors arm slide blocks (refer
to Figure 8.14). They must be free to move without
obstruction. There is one slide block on each side of
the chassis.
Figure 8.14 – Front of Chassis
2. Raise the platform from the lower controls and visu-
ally inspect the slide blocks underneath the front of
the platform (refer to Figure 8.15). There is one slide
block on each side of the platform. The slide blocks
must be in good condition and free to move without
obstruction.
handle at the rear of the chassis is used for emer-
gency lowering (refer to Figure 8.13).
Figure 8.13 – Emergency Lowering Control
Danger
Pinch points may exist between moving components.
Death or serious injury will result from becoming
trapped between components. Make sure all person -
nel stand clear while lowering the platform with the
emergency lowering lever.
3. Make sure there is nothing in the way to obstruct the
platform when it lowers.
4. While standing clear of the scissors structure, engage
the control. The platform will begin to lower as the
lever is pushed down.
S1930E and S1932E machines – push downward
on the lever to lower the platform.
S2632E machines – pull outward on the handle to
lower the platform.
5. Release the lever/handle to stop the platform from
lowering.
