You must have written approval from the manufacturer before making any modification or addition that affects the safe operation, stability, intended use, or the mechanical, hydraulic, or electrical integrity of the aerial lift. Make sure the modified aerial lift is:
(1) At least as safe as it was before being modified; and
(2) Any change to the insulated portion of the aerial lift does not reduce the insulating value.
Note: | If the original manufacturer is no longer in business, an equivalent entity such as a nationally recognized testing laboratory may approve modification. |
