4 Used machine evaluation requirements
4.1 General
The requirements in this clause are provided to allow the owner, seller or their representative to evaluate used machines relative to the information provided by the manufacturer in the machine operator’s manual to verify that the used machine is functioning as intended by the manufacturer.
An inspection form for used machines in four sections (see example in Annex A) may he used to provide information on the machine under inspection.
a) The upper section of the first page provides specific identification of the used machine.
b) The middle section of the first page provides a checklist to document the results of a used machine inspection. A check in the box by each inspection item indicates that the used machine is functioning properly as intended by the manufacturer as stated in the operator’s manual.
cJ The lower section of the first page has information about the inspection person.
d) The section on the second page provides a detailed inspection list based on this document’s requirements.
4.2 General requirements

h) The engine functions without leakage from the lubrication, cooling, intake, exhaust and fuel delivery systems. Slight leakage is acceptable.
i) Tanks do not have leakage or substantial permanent deformation.
j) Drivetrain system delivers power and shifts gears smoothly without abnormal noise.
k) Hydraulic systems (such as hydraulic pumps, multiple-function valves, hydraulic motors, etc.) run without leakage or abnormal noise. Hydraulic hoses and tubes are fastened correctly without damage. Hydraulic cylinders do not have leakage, damage or bending.
1) Steering system works correctly without jerking or excessive deadband.
m) Fluid level indicators for fuel and hydraulic tanks, if provided, function correctly. Pressure devices in the tanks, such as vent or safety valve, function properly.AS ISO 10987.3 pdf download.
