position, an indicator light above it turns "ON."
When the auto idle selector button is pushed again, it is
turned "OFF" and the engine speed will return to the
setting of the engine speed dial and will remain at this

dial is moved.

oil flow rate.
The flow control button is used to set the flow rate of pump
