(10) Hydraulic and pneumatic filters for cleanliness and the presence of foreign
material in the system indicating other component deterioration.
(11) Electrical systems and components for deterioration or wear including those
not readily visible on a frequent inspection.
(12) Performance test of all boom movements.
(13) Condition and tightness of bolts and other fasteners.
(14) Welds, as specified by the manufacturer.
(15) Legible and proper identification, operational, and instructional markings.
(16) If the aerial device is rated as an insulated device, the electrical insulating
components and system(s) shall be thoroughly inspected for lack of cleanliness
and other conditions that compromise insulation. Then these components and
system(s) shall be tested for compliance with the rating of the aerial device in
accordance with one of the applicable methods and procedures as outlined in
section 5.4.3 of this standard:
(a) If the aerial device is used for AC bare-hand work, the unit shall undergo a
60 Hz test as shown in Table 2 at least every three years;
(b) If the aerial device is used for DC bare-hand work, the unit shall undergo a
DC test as shown in Table 2 at least every three years;
(c) After repair or modification of any component that crosses the insulating
system(s), or the repair or replacement of an insulating component(s), the
unit shall be dielectrically tested in accordance with section 5.4.3;
(d) An insulated replacement boom shall be tested to insure conformance to
5.3.3 by the supplier;
(e) Bare-hand work units shall be tested as shown in Table l after any major
repair to the insulated boom or any insulated boom replacement. Any
suspected items shall be carefully examined or tested and a determination
made by a qualified person as to whether they constitute a safety hazard. All
unsafe items shall be replaced or repaired before use.
8.3 Inspection and Test Records.
(l) Items to be inspected shall be designated to the operator or other authorized
person making frequent inspections. Records of frequent inspections need not be
made. However, where a safety hazard is found, it shall be reported in writing to a
person responsible for the corrective action and that report and a record of the
correction shall be maintained for five years, or as required by applicable
regulations.
(2) Written, dated and signed reports and records shall be made of periodic
inspections and tests and retained for a period of five years or as required by
applicable regulations.
8.4 Maintenance. Maintenance and frequency of maintenance shall be determined by
the owner in accordance with the manufacturer’s recommendations. Welding repairs
of components or welds, designated as critical in the manufacturers manual, shall be
made in accordance with the manufacturers recommendations. Should the original
manufacturer no longer exist an equivalent entity may determine the required
procedure.
8.4.1 Maintenance Training. The owner shall train their maintenance personnel in
inspection and maintenance of the aerial device in accordance with the
manufacturer’s recommendations and Section 8 of this standard.
8.5 Modifications. No modifications or additions which affect the stability, mechanical,
hydraulic, or electrical integrity or the safe operation of the aerial device shall be
made without the written approval of the manufacturer. If such modifications or
changes are made, the capacity, operation, and maintenance instruction markings
shall be changed accordingly. In no case shall the safety factors be reduced below
those specified in this standard or below the manufacturers design safety factors,
whichever are greater. Should the original manufacturer no longer exist, an
equivalent entity may approve required modification.
8.6 Weight Distribution. Changes in loading or additions made to the mobile unit after
the final acceptance that affect weight distribution shall meet applicable regulations
