1.9 SERIAL NUMBER LOCATIONS
For machine identification, a serial number plate is affixed
to the machine. The plate is located on the left side of the
frame, between the bearing area and the left rear wheel. If
the serial number plate is damaged or missing, the
machine serial number is stamped on the left side of the
frame, at the center top, below the turntable bearing; the
serial number is also stamped on the left side of the turn-
table, at center, along the left turntable upright close to the
bearing area. In addition, the last five digits of the serial
number are stamped on the top left of the fly end of each
boom section.
