MAINTENANCE GUIDELINES
PREVENTATIVE MAINTENANCE
A preventative maintenance program based on the manufacturer's recommendations shall be established.
Dated and detailed inspection and repair records shall be maintained.
It is recommended that the replacement parts for your Aerial Device be obtained from a Terex South Dakota
distributor or Terex South Dakota.
MAINTENANCE PROCEDURE
Before maintenance, adjustments, and repairs are started the following precautions shall be taken as
applicable:
• You must be authorized by owner to operate unit.
• Place vehicle where it will cause the least interference with other equipment or operations in the area.
• All controls at the off position.
• Starting means rendered inoperative.
• Warning or “OUT OF ORDER” signs placed on the vehicle.
• Power plant stopped or disconnected at power takeoff.
• Relax all hydraulic cylinders used for boom lift and articulation.
• Relieve hydraulic oil pressure from all hydraulic circuits before loosening or removing hydraulic
components.
After adjustments and repairs have been made, the Aerial Device shall not be operated until all guards have
been reinstalled, trapped air removed from hydraulic system, safety devices reactivated, and maintenance
equipment removed.
Warning or “OUT OF ORDER” signs shall be placed and removed by authorized personnel only.
ADJUSTMENTS AND REPAIRS
Any unsafe conditions disclosed by the inspection requirements of this section shall be corrected before
operation of the Aerial Device is resumed. Adjustments and repairs shall be done only by qualified
personnel.
Adjustments shall be maintained to assure correct functioning of components. The following are examples:
• All functional operating mechanisms.
• Safety devices.
• Control systems.
• Power plants.
Repairs or replacements shall be provided promptly as needed for safe operation. The following are
examples:
• All critical parts of functional operating mechanisms which are cracked, broken, corroded, bent or
excessively worn. This is for all parts of the Aerial Device, pedestal, subframe, outrigger, and
attachments to the vehicle.
• All critical parts of the vehicle structure which are cracked, bent, broken or excessively corroded.
• Hooks showing defects disclosed by “Frequent Inspection” requirements in the maintenance manual
shall be discarded. Field repairs by welding or re-shaping shall not be permitted.
All replacement parts or repairs shall have at least the original safety factor. Do not alter, modify, remove or
replace any part of the Aerial Device without the approval of the manufacturer.
NOTE: Do not use hoses having less than 3000 PSI (20.69 MPa) working pressure. Only use
orange hoses marked "Non-Conductive" for hydraulic tools at the boom tip and in areas
that bridge the insulation gap.
