STAND CLEAR of the work platform while performing the following checks.
Before operating the work platform, survey the work area for surface hazards such as holes, drop-offs,
bumps and debris.

5. Visually inspect the elevating assembly, lift cylinder, cables, and hoses for cracked welds and structural
damage, loose hardware, hydraulic leaks, loose wire connections, and erratic operation. Check for miss-
ing or loose parts.
