AIRPLANE & SYSTEMS DESCRIPTIONS
rM~,402C
Make certain that both engines are functioning properly with the syn-
chrophaser
turned OFF. Since the left propeller is slaved to the right
propeller, and the slaving range is limited, the synchrophaser should not
be operated at either extreme of the RPi~ governing range.
For
best operation, it is important to guard against propeller control
creeping by setting the quadrant friction lock tightly, see figure 7-1. On
extended flights, it may be necessary to periodically switch to the OFF
position, reset the propeller control levers and reengage the synchro-
phaser.
...--------NOTE--------.,
Manually synchronize the propellers as close as
possible prior to selecting the PHASE position.
