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. Turn the nuts
counterclockwise to relieve tension and clockwise to
increase tension. Refer to fi gure 19 on page 12.
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 fi gure 28.

CAUSE
Lift mechanism is binding
Handle tube is binding on lift rod.
Lock mechanism is out of adjustment Lock mechanism is out of adjustment
and is not disengaging.
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 disengage from the slots in the
pivot plate. See fi gure 29.
