Work lamps are located on the boom and front body (tool
box) of the machine. An optional set of three additional
work lamps can be fitted to the cab and counter weight.
When the work light switch is moved to the first position,
the input i/p 9 (A-28) to the ECU1 is selected. This in turn
enables outputs to be turned on to the Boom, ECU1 o/p 29
(C-39) and lower front body (Tool Box), ECU1 o/p 30 (C-
20).
A second press of the same switch selects ECU1 i/p 12 (A-
17) and i/p (A-28) which in turn energises the second
optional set of cab work lamps, ECU1 o/p 13 (C-5) and o/
p 14 (C-6) and counter weight, ECU1 o/p 33 (C-18), if they
are fitted and provided that these options have been
selected in the machine setup tool.
The switch is returned by pressing in the reverse direction
boom and tool box work lamps and the optional work
lamps are extinguished.
