Power Band Maps
Each machine model is mapped with the most applicable
engine rpm and corresponding hydraulic pump output.
The applicable table shows the no load engine rpm and
output in mA to the pump proportional solenoid valve.
The total rotation of the hand throttle control knob is
divided into seven 'power bands'.
Note: The hand throttle control knob does not select the
H+ power band. The H+ button selects the H+ power band.
K H+ Button ( T C-75)
The engine rpm and hydraulic pump output change within
the power bands, depending on the rotation of the hand
throttle control knob.
