Section 3 Basic Operation
Operating the
Lifting Hydraulic System
The lift cylinders may after a period of time get out of
time or phase. The effects of this can be seen when one
side of the drill is running too low or too high because its
lift cylinder is either overextended or overretracted com-
pared to the other lift cylinder. To rephase the cylinders,
raise the drill completely up and hold the tractor hydrau-
lic lever on for a few seconds to give the cylinders time to
rephase. This should be done each time the drill is
raised out of the ground. Momentarily reversing the hy-
draulic lever immediately after rephasing to allow the cyl-
inders to retract about 1/2" will help in maintaining a level
drill.
Transporting
Operating Transport Lock
Refer to Figure 3-1:
When transporting your drill, you should always lock
your drill in the raised position. Fully extend the lift cylin-
ders to raise the drill for transporting. Remove the lock
pins from the storage position, Figure 3-1. {One on each
side of the drill frame.}
Refer to Figure 3-2:
Place the lock pin through the frame channel as shown
in Figure 3-2. Before lowering the drill, you must first ex-
tend the lift cylinders completely and move the lock pins
to their storage position.
Lock Out Hubs
Before transporting the drill, you should always check
the following items:
1. Make sure that drill is securely attached to the draw
bar of the tractor and that the hitch safety chain has
been securely attached.
2. Check to see that the transport tires have the proper
inflation as noted on page 6.
Refer to Figure 3-3:
3.
Make sure the drive lockout hub (left side) is disen-
gaged before transporting, see Figure 3-3. This will
protect from excessive wear on the gauge wheel
drive system.
4. This drill comes equipped with a transport lock pin
located on each side of the drill frame. Make sure
the pin is in its transport position as shown in
Figure 3-2.
5. Comply with all federal, state and local safety laws
when traveling on public roads.
6. Remember, the drill is wider than the tractor and ex-
treme care must be taken to allow for safe clear-
ance.
!
WARNING!
This drill should never be pulled faster than 20 miles per hour.
