To Adjust Blade Spring
The tension of the blade adjust spring may be altered
to permit the blade to tilt forward to bypass solid
obstructions. To change the spring tension, adjust
the nuts at upper end of the spring bolt. Standing in
front of blade, turn the nuts counterclockwise to
relieve tension and clockwise to increase tension.
Refer to figure 13 on page 8.
To Adjust Blade Shoes
The blade shoes at the ends of blade may be raised
for close work on smooth surfaces or lowered to raise
the blade to work on rough or uneven areas. Make
sure both shoes are set evenly and that the nuts are
tightened securely. See figure 22.

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 disengage from
the slots in the pivot plate. See figure 23.
