(applies to drills with serial numbers A1058W-
for serial number A1059W+, see page 44)
Refer to Figure 35
The rear lift-assist wheels each have independent
adjusters for the caster pivot. The adjustments will vary
depending on different field-to-field conditions as well as
road transport conditions.
If the caster is oscillating during transport turns or in field
use, adjust the pressure plate bolt
.
Refer to Figure 36
The factory setting for both adjustments is

3 ⁄
4
in. (4.4 cm) from the face of the bolt head to the top
of the weldment, this measurement is a starting point
and will need to be fine tuned from field-to-field as
conditions vary. Depending on conditions, adjustment
may be needed to go from field to road transport. If
caster brake components are ever replaced, return the
bolts to the factory setting.
