Important Safety Information
Look for Safety Symbol
The SAFETY ALERT SYMBOL indicates there is a
potential hazard to personal safety involved and extra
safety precaution must be taken. When you see this
symbol, be alert and carefully read the message that
follows it. In addition to design and configuration of
equipment, hazard control and accident prevention are
dependent upon the awareness, concern, prudence and
proper training of personnel involved in the operation,
transport, maintenance and storage of equipment.
Be Aware of Signal Words
Signal words designate a degree or level of hazard
seriousness.
DANGER indicates an imminently hazardous situation
which, if not avoided, will result in death or serious injury.
This signal word is limited to the most extreme situations,
typically for machine components that, for functional
purposes, cannot be guarded.
WARNING indicates a potentially hazardous situation
which, if not avoided, could result in death or serious
injury, and includes hazards that are exposed when
guards are removed. It may also be used to alert against
unsafe practices.
CAUTION indicates a potentially hazardous situation
which, if not avoided, may result in minor or moderate
injury. It may also be used to alert against unsafe
practices.
Prepare for Emergencies
Be prepared if a fire starts
Keep a first aid kit and fire extinguisher handy.
Keep emergency numbers for doctor, ambulance, hospital
and fire department near phone.
Be Familiar with Safety Decals
Read and understand “Safety Decals” in Operator
manual.
Read all instructions noted on the decals.
Keep decals clean. Replace damaged, faded and illegible
decals.

CTA4500 & CTA4500HD Table of Contents Important Safety Information 2
Avoid High Pressure Fluids
Escaping fluid under pressure can penetrate the skin,
causing serious injury.
Avoid the hazard by relieving pressure before
disconnecting hydraulic lines.
Use a piece of paper or cardboard, NOT BODY PARTS, to
check for suspected leaks.
Wear protective gloves and safety glasses or goggles when
working with hydraulic systems.
If an accident occurs, seek immediate medical assistance
from a physician familiar with this type of injury.

Maximum transport speed for air drill is 20 mph (32 kph).
Some rough terrains require a slower speed. Sudden
braking can cause a towed load to swerve and upset.
Do not exceed 20 mph (32 km/h). Never travel at a speed
which does not allow adequate control of steering and
stopping. Reduce speed if towed load is not equipped with
brakes.
Comply with state and local laws.
Do not tow an air drill unless the towing vehicle is rated
for, and ballasted for, the weight of the air drill.
Carry reflectors or flags to mark air drill in case of
breakdown on the road.
Do not fold or unfold the air drill while the tractor is
moving.
Practice Safe Maintenance
Understand procedure before doing work. Use proper
tools and equipment. Refer to this manual for additional
information.
Work in a clean, dry area.
Lower the air drill, put tractor in park, turn off engine,
and remove key before performing maintenance.
Make sure all system pressure is relieved.
Inspect all parts. Make sure parts are in good condition
and installed properly.
Remove buildup of grease, oil or debris.
Remove all tools and unused parts from air drill before
operation.

Setup
This section covers mating the implement to a
compatible air cart, and final setup items on the
implement.
Some of these items are repeated in the cart and
implement Operator’s Manuals. The Operator’s Manuals
may also have additional setup items that may be
appropriate to accomplish prior to delivery (such as
installing the seed monitor in the tractor, if the tractor is
available).
Hitching
When transported by the customer, the air drill is part of
a train that includes the tractor and the assembly (the
cart and the air drill).
When hitching for pre-delivery setup, hitch the leading
cart to the tractor first.
Once the cart is hitched to the air drill, it is usually left
connected, unless parking or storage considerations
require separation.
This manual includes full details only for the air drill’s
hitch. Consult the cart manual for cart-to-tractor hitching.
Equipment Damage Risk:
If the tractor has a load-sensing or constant-flow hydraulic
system, the air drill must be equipped with an optional bypass
valve to avoid tractor damage. See the CTA4500 &
CTA4500HD Operator’s Manual for ordering and setup
information for the bypass kit.
Crushing Hazard:
You may be severely injured or killed by being crushed
between the tractor, cart and air drill. Do not stand or place
any part of your body between machines being hitched. Stop
tractor engine and set park brake before installing hitch pins.

ADC2350/ADC2350 Hydraulic Connections
Only trained personnel should work on system hydraulics!
Escaping fluid under pressure can have sufficient pressure to
penetrate the skin, causing serious injury. Avoid the hazard by
relieving pressure before disconnecting hydraulic lines. Use a
piece of paper or cardboard, NOT BODY PARTS, to check for
leaks. Wear protective gloves and safety glasses or goggles
when working with hydraulic systems. If an accident occurs,
seek immediate medical attention from a physician familiar
with this type of injury.
The standard air drill has one hydraulic circuit (with a low
pressure relief valve return line). The standard circuit
powers lift, fold and weight-transfer functions, controlled
by a valve block on the right front of the air drill.
Raise/Fold Hose
This hose is connected to valve block port “V3” on the
implement. Connect it to port “C” on the cart.
Lower/Unfold Hose
This hose is connected to valve block port “V4” on the
implement. Connect it to port “D” on the cart.
Relief Valve Return
This hose is connected to valve block port “DUMP” on
the implement. Connect it to port “G” on the cart.
Check hose routing to ensure adequate slack for link arm
movement, and clearance from pinching or abrading
cart/air drill components.
Equipment Damage Risk:
If the tractor to be used has a load-sensing or constant-flow
hydraulic system, the drill must be equipped with an optional
bypass valve to avoid tractor damage. See Options section of
Operator manual for ordering.
Equipment Damage Risk:
DO NOT connect the Sump return line to a tractor power-beyond-port.

Bleeding Hydraulics
To function properly, the hydraulics must be free of air. If
hydraulics have not been bled, they will operate with
jerky, uneven motions and could cause wings to drop
rapidly during folding or unfolding. During initial
implement setup complete the following procedures.
Escaping fluid under pressure can penetrate skin, causing
serious injury. Avoid the hazard by relieving pressure before
disconnecting or “cracking” hydraulic lines. Use a piece of
paper or cardboard, NOT BODY PARTS, to check for leaks.
Wear protective gloves and safety glasses or goggles when
working with hydraulic systems. If an accident occurs, seek
immediate medical attention from a physician familiar with
this type of injury.
Bleed only at a JIC (Joint Industry Conference, 37  flare) or
NPT (National Pipe Thread, tapered thread) fittings, and
never at ORB (O-Ring Boss) fittings.
Bleeding Lift Hydraulics
1. Check hydraulic fluid level in tractor reservoir and fill
to proper level. Filling a completely empty lift cylinder
set requires about 2 gallons of oil.
Refer to Figure 13
2. Manual Valve: Set both valve levers to the Field
position.
Although the fold cylinder valve handle is set to
FIELD, fold cylinders may still be activated by the
Weight Transfer circuit.
Refer to Figure 14
3. Electric Valve: Press the frame control softkey
to activate the fold/unfold button.
When the fold/unfold button is highlighted, the tractor
remote lever can be used to fold and unfold the
machine.

4. Refer to Figure 15
5. Make sure the implement is still unfolded and rod
ends of the fold cylinders are still disconnected.
Place a support under the cylinder end so
extending rods will not contact anything.
6. Jack up and support implement frame high enough
so opener cylinders can be fully extended. Use a
jack set rated for the weight of the air drill (see
Appendix of Operator’s Manual). Fully extend
opener-lift cylinders.
Refer to Figure 16
7. Turn knobs , on pressure-control valves
completely counterclockwise, then turn them back
far enough (about three clockwise turns) to build up
at least 1000 psi pressure per gauge , .

8. Loosen JIC hose fittings at locations shown.
9. Slowly engage hydraulic remote lever to lower
openers, until oil begins to appear at loosened
fittings. Continue engaging lever until all air has
been expelled, then tighten that fitting. Continue to
supply oil until no oil appears at loose fittings when
openers are completely lowered.
10. Slowly engage hydraulic remote lever in to raise
the openers until oil begins to appear at loosened
fittings. Continue engaging the hydraulic remote
lever until all air is expelled, then tighten that fitting.
Continue to supply oil until no oil appears at loose
fittings when openers are completely raised.
11. Cycle openers up and down about 10 times. Each
time you lower openers, hold tractor remote lever
until opener-lift circuit builds up to pressure set.
