Blocking the Mast

Always block the mast when the platform is raised before
inspecting or performing service or maintenance proce-
dures on the machine.
Danger
Pinch points exist on the aerial platform. Death or
serious injury will result if the platform drops onto
personnel working under the raised platform. Prop-
erly block the mast when the platform is raised, be-
fore inspecting or performing service or maintenance
procedures on the machine.

physical damage such as loose connections, broken
wires, and frayed insulation.
2. Check the wiring in areas where a change in routing
direction may cause them to become pinched.
3. Make sure the cables and wires are properly routed
to avoid sharp edges, pinching, and scuffing.
