Note:
a) The platform height plus the operator height (taken as 2m [6ft 7in]) is the working height.
b) The maximum horizontal reach plus the arm length of the operator (taken as 0.6m [1ft 11in]) is the maximum horizontal
working envelope.
c) The ground bearing data is approximate, without considering different options, thus it is applicable only in adequately safe
conditions.
d) In different areas, hydraulic oil, engine oil, coolant, fuel and lubricant should be added in accordance with the environmental
temperature.
e) In cold weather, auxiliary devices are needed to start the machine.
f) Rated platform load capacity refers to the maximum allowable load on the platform, including the weight of persons,
