SERVICE AND ADJUSTMENTS
FIGURE 26
To Adjust the Blade Pivot Lock Mechanism
If the blade will not unlock and pivot, the angle lock
bars are not disengaging from the slots in the pivot
plate. To correct, adjust the 5/16" hex jam nuts to draw
the end of the control cable back towards the cable
mount bracket. The less the threaded end of the cable
extends through the bracket, the more the angle lock
bars can retract to dis en gage from the slots in the
pivot plate.
