SERVICE AND ADJUSTMENTS

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.

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.
