B. Finger control service port system
a. Feature and purpose
1 The service port pedal has been replaced by a lever-top knob switch: Feather-touch finger control
realized.
2 The breaker can easily be operated with a button switch.
3 Optimum control feeling adjustments can be made for maneuvering various attachments efficiently.
4 Safe attachment handling is ensured through fool proof control.
When a thumb (and tilt bucket) attached, the foot pedal has been used to operate. It has not been
easy for fine control in this way. Such operation can now be finely controlled with your hand (thumb)
and you can ensure more space around your feet.
Service port functions have been tremendously upgraded.
