Box Alignment
To check and adjust box alignment:
1. Place a block ahead of each wing gauge
wheel. Pull drill forward against blocks to rock
frames back. Pull forward until stop bolts are
firmly against toolbars.
Refer to Figure 4
2. Check for proper alignment by running a
string line across back of drill toward outer
ends of wings. For proper alignment, outside
ends of boxes (dimension A) should be 1/4-
inch to 1/2-inch ahead of inside ends (dimen-
sion B).
Refer to Figure 5
3. To adjust box alignment, shorten or lengthen
stop bolts to change the contact point with the
toolbars. Adjust stop bolts (1) in or out until di-
mension A is 1/4-inch to 1/2-inch greater than
dimension B.
