Visual Inspection: Before use: Quickly check the shell for severe bumps, deformation, cracks (especially at the explosion-proof joint surfaces). After use: Check for new damage or abnormal wear. Chain: Inspect for twisting, dead knots, cracks, severe wear (noticeable reduction in chain ring diameter), excessive stretching, rusting. Hook: Check for deformation, cracks, wear (especially at the hook mouth and dangerous cross-sections), whether it rotates flexibly, and if the anti-dropping device is intact and effective. Sprocket/Gear: Visually inspect for broken teeth, severe wear. Operating hand zipper: Check if it is intact, and if pulling feels smooth without any noise or jamming. Signboard: Check if the explosion-proof mark, rated load, warning signs, etc., are clear and legible.
