1.11 SERIAL NUMBER LOCATION

A serial number plate is affixed to the left rear front of the
turntable. If the serial number plate is  damaged or miss-
ing, the machine serial number is stamped on the left side
of the frame between front and rear wheels, below turnta-

ble bearing. In addition, the last five digits of the serial
number are stamped on top of the fly, mid and base end
of the boom and on the left side of the turntable.
