Operation
33. Engine power mode selector switch
Use this switch (33) to switch the engine output to match the
purpose of the operation.
When the power mode, the output mode pilot lamp (power
mode) on the machine monitor lights up. In addition, the econ-
omy mode pilot lamp (ECO) goes out.
Power mode (high engine output)
Fast operations with emphasis on production.
Economy mode (low engine output)
Operations with time to spare in the cycle time with empha-
sis on fuel consumption.
REMARK
For normal operations, use the economy mode to improve the
fuel consumption.
When used together with the accelerator, it helps to reduce fuel
consumption.
With the power mode, the maximum output is provided accord-
ing to the amount of the accelerator pedal is depressed.
Use this particularly when the work must be completed in a short
cycle time.
Even if the engine is stopped in power mode, when the engine is
started again, it will start in economy mode.
(In some territories, the default mode is set to power mode. If it
is desired to change the default to the economy mode, please
consult your KOMATSU distributor.)
