Blade Height Adjustment
Refer to Figure 2-1:
WARNING
!
To avoid serious injury or death:
Always keep your body extremities out from under the blade
carrier when adjusting cutting blade height. The blade carrier
can fall while loosening its bolts.
The blade carrier (#1) can be lowered or raised equal
amounts on both sides of the scraper to grade a surface
level. Position cutting edges even with the bottom of skid
shoes for non-aggressive grading action or infinitely
adjusted downward to 1 1/2" below skid shoes for highly
aggressive cutting action. The most commonly used
setting is 1/4" below skid shoes.
The blade carrier (#1) can also be lowered on the right
side more than on the left side to grade a crown in the
middle of a roadway.
