Which statement is true regarding the side of the aerial that is short jacked?

• A. Operate the aerial only at low speed
• B. Never operate the aerial on that side
• C. Operate the aerial during maintenance
• D. Deactivate stabilizers first

Answer: (B)

Stability with a level, fully supported base is the core idea here. If one side of the aerial is on a short jack, that side isn’t providing proper support and the platform is uneven. As you extend or move the boom, the uneven base creates a tipping moment and the risk of the unit tipping or collapsing rises. The safest rule is to never operate the aerial on that side until the stabilization is corrected. Reposition or replace the jack so the unit rests evenly on solid supports, or retract and reset the stabilizers to restore level support. Speed or maintenance arguments don’t fix the underlying stability issue, and relying on deactivating stabilizers isn’t a safe remedy either.
