Caster Pivot Locks
Refer to Figure 9
To prevent side movement of the drill when transported
by trailer, the lift-assist casters may be locked in their full-
reversing orientation. A spring-loaded pin engages a
cutout in the caster pivot plate, preventing rotation.
Use this feature only for trailer transport. Do not use
these locks for towing drill on own wheels or field opera-
tions.
Locking Casters
Refer to Figure 9 and Figures 7 and 8 on page 18
1. With drill hitched, raise drill (page 18). Install lift lock
channels.
2. Begin backing drill toward trailer until casters swing
into reverse and drill is aligned with trailer. Stop a
short distance from the trailer.
3. Lift locking cross-pin out of upper (disengage-
ment) detents. Rotate cross-pin and release into
deeper locking detent
4. Continue backing drill until lock tubes are aligned
with plate cutout , and pins engage cutouts.
Do not continue onto trailer unless both lock pins are engaged.
Unlocking Casters
1. Hitch drill before unlocking.
2. Leave the lock pins in place until the drill is removed
from the trailer, unless the trailer bed has more than
ample width to permit casters to safely make a full
turn.
3. At each caster, lift cross-pin out of lower (lock
engagement) detent . Rotate cross-pin and
release into upper (disengagement) detent.
