Box Alignment
To check and adjust box alignment:
1. Unfold drill, see “Unfolding the Drill,” page 23,
and 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 6
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 0-to-
1/4” ahead of inside ends (dimension B).
Refer to Figure 7
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 0 to 1/4” greater than dimension
B.
Note: If you have trouble getting box aligned it
may be necessary to adjust fold cylinders, re-
fer to “Adjusting Fold Cylinders” page 18. Do
not over-adjust or you may cause fold latching
problems.

Note: Box alignment, fold cylinder and tongue
spacer shim adjustments are closely interrelat-
ed and may have to be adjusted in tandem. Ad-
just fold cylinders to enable complete 90
degrees of travel to latch wings and to unfold
for box alignment. Then adjust tongue shims to
remove as much play as possible in transport
without preventing proper latch operation.
Lack of proper fold cylinder adjustment will cause
difficulties with gage wheels by not allowing full ro-
tation of gauge wheel assemblies.
