• Base Weldment
- Ensure there are no visible cracks in
welds or structure and there are no signs
of deformation.
• Wheel/Tire Assembly
The aerial platform is either equipped with
air tires or foam-filled tires. Tire and/or wheel
failure could result in an aerial platform
tipover. Component damage may also result
if problems are not discovered and repaired
in a timely fashion.
WARNING
Air filled tires are not permitted on some
models. Refer to Table 4.7.
WARNING
An over-inflated tire can explode and
may cause death or serious injury.
- Check all tire treads and sidewalls for
cuts, cracks, punctures and unusual
wear.
- Check each wheel for damage and
cracked welds.
- Check each lug nut for proper torque to
ensure none are loose.
To maximize stability, it is essential to maintain
proper pressure in all air-filled tires.
- Check each tire with an air pressure
gauge and add air as needed.
Refer to Table 4.7 for wheel/tire specifications.
WARNING
Intermixing tires of different types or
using tires of types other than those
originally supplied with this equipment
can adversely affect stability. Therefore,
replace tires only with the exact Skyjack-
approved type. Failure to operate with
matched approved tires in good condition
may result in death or serious injury.

there are no loose or missing parts, all
fittings and hoses are properly tightened
and there is no evidence of hydraulic
leakage.
• Steer Cylinder Assembly
- Ensure steer cylinder assembly is
properly secured, there are no loose
or missing parts, all fittings and hoses
