Hydraulic Fitting Identification
GENERAL SERVICE INFORMATION
NOTE: Read instructions carefully before you beginning any procdure.
1. Be sure to read and follow all instructions to ensure
proper assembly, operation, and service of the
implement.
2. Service may require the use of a forklift or other
suitable lifting device.
3. Implement must be serviced on a flat surface.
4. Left and right directions are determined from the rear
of the implement facing the forward direction of travel.
5. Use a suitable sealant on hydraulic connections;
sealant paste is recommended. Be careful to prevent
sealant from entering the hydraulic system.
6. Apply a thread sealant to all female-to-male pipe
thread connections.
7. Do not allow tape to enter the hydraulic system.
8. Do not use a thread sealant on ORB or swivel fitting
connections.
NOTE: If you are assembling or servicing the
implement inside of a building, ensure the door
opening is large enough to allow the
implement to be removed after assembly.
Check the Specifications Tables in this section
for the overall height and width in transport
position.
NOTE: Additional bolt torque information can be
found later in this section.
NOTE: Pipe thread fittings (1), O-ring boss fittings (2) and JIC fittings (3) may be the types of hydraulic fittings used.

CAUTION!
GENERAL SAFETY PRACTICES
REVIEW this manual and operator’s manual before
servicing equipment.
NEVER allow anyone unfamiliar, untrained, or
complacent to operate the air drill.
ALWAYS USE the jack supplied when unhooking the air
drill.
ALWAYS ensure weight of towing vehicle is heavier than
implement.
NEVER transport the air drill at speeds higher than 30
km/hr (18 mph).
NEVER transport Drill/cart combination with product in
tank.
MAINTAIN YOUR AIR DRILL in proper working
condition. Unauthorized modifications to the machine
may impair function and/or safety and affect machine life.
BE SURE the air drill is securely fastened to a large farm
tractor or an air cart that is attached to a large farm tractor
before operating hydraulics.
USE EXTREME CARE when making adjustments.
KEEP CHILDREN AWAY from all farm equipment.
SERVICING SAFETY PRECAUTIONS
BLOCKthe wheels to prevent movement when servicing. BE SURE the press wheels are blocked and wing lock pins
are in place before servicing or adjusting opener
assemblies or working on the air drill.
The tractor engine should be stopped and the
wheels blocked to prevent any movement during
servicing.
Always be sure that the depth control safety lock
is in place when servicing the air drill.
Always be sure the wings are in field position
before servicing the air drill.
Escaping hydraulic fluid is a serious hazard.
Escaping hydraulic fluid that is under pressure can
penetrate the skin, causing serious injury. Relieve
pressure before disconnecting the hydraulic lines.
Check/tighten all connections before applying
pressure.
Never use your hand to search for leaks. Use a
piece of cardboard or paper. If any fluid is
injected into the skin, seek immediate medical
attention. Gangrene may result if the wound is
not treated within a few hours. Check your
hydraulic fluid containers for warnings concerning
the hydraulic fluids you use.
DO NOT walk within the radius of raised air drill
wings.

SAFETY DURING OPERATION
DO NOT ALLOW ANYONE ON THE AIR DRILL while
operating the air drill hydraulics.
NEVER disconnect the tractor from the air drill while the
air drill wings are raised.
KEEP CHILDREN AWAY from the air drill during
operation.
NEVER STAND within the radius of the raised wings.
Hydraulic or mechanical failure may result in rapid or
uncontrolled falling of the wings.
RAISE AND LOWER the wings only on level ground
with the depth control fully raised.
PARK ON LEVEL GROUND and block adequately
before servicing.
AVOID moving machines.
DO NOT sit or ride on moving implements. Death or
injury may result.
DISENGAGE POWER AND SHUT DOWN the tractor
engine (remove the key from the tractor ignition), be
certain that all moving parts have stopped, and all pressure
in the system is relieved BEFORE cleaning, adjusting or
lubricating the air drill.

KEEP service area clean to prevent injury to service
technicians and others.
DO NOT enter tight areas. Be aware of pinch zones prior
to commencing work.

AIR AND AIR HOSES
COMPRESSOR HOSES may move unexpectedly when
suddenly disconnected.
USE PROPER air nozzles. Do not use compressed air to
clean clothes or direct it toward any part of yourself.
AVOID getting chemicals into eyes. Use eye protection.
HYDRAULICS AND HYDRAULIC LEAKS
AVOID high-pressure fluids.
ESCAPING HYDRAULIC FLUID IS A SERIOUS
HAZARD. Escaping hydraulic fluid under pressure can
penetrate the skin causing serious injury. Relieve pressure
before disconnecting the hydraulic lines. Check/tighten
all connections BEFORE applying pressure.
BEWARE excessive hydraulic pressure. Explosive
structural failure can result.
BEWARE air locks in cylinders. Large cylinder
displacements can occur without hydraulic oil flow.

SHIELDS
REPAIR damaged shields.
KEEP all shields in place.
BE EXTRA CAUTIOUS when repairing or servicing
without protective shields.
ELECTRICAL
REMOVE the ground wire to avoid arcing contacts.
REMOVE GROUND WIRE when welding.
TIRES
USE A CAGE IF POSSIBLE when setting tires on rims.
AVOID excessive air pressure.
DO NOT OVER-INFLATE TIRES. NEVER lean over a
tire while inflating it.

SECTION 1 - GENERAL INFORMATION

SAFETY DURING TRANSPORT
CHECK with local authorities regarding transport on
public roads. Obey all applicable laws and regulations.
ONLY TOW at a safe speed (30 km/hr/18 mph). Use
caution when turning corners or meeting traffic.
BE SURE transport lighting is plugged in and that the red
taillight(s), amber flashers, and amber signal lights are all
working properly.
ALWAYS be certain that no one is behind or near the air
drill before moving it.
BE SURE all safety transport locks are in place before
transporting the air drill.
BE SURE the reflector decals are clearly visible from all
sides of the air drill and the ‘Slow Moving Vehicle’ sign is
at the rear of the air drill in clear view of overtaking traffic.
BE SURE the tractor weight is equal to or greater than the
total weight of the air cart and air drill.
BE SURE all the wheel bolts are torqued to proper
specifications before transporting the air drill.
WATCH for power poles and overhead power lines.
ALWAYS lock the tractor drawbar when transporting the
air drill.
ALWAYS park the air drill on level ground and block the
wheels before unhooking from the towing vehicle.
NEVER subject the air drill to steep side grades while in
transport position.
ALWAYS use the hitch jack supplied with the air drill
when unhooking from the tractor.
NEVER brake or decelerate during cornering.
ALWAYS enter corners slowly. SLOW the machine to
turning speed before entering a corner. DO NOT
decelerate while executing the turn.
SAFETY DECALS
KEEP SAFETY DECALS CLEAN. Wipe clean when
necessary.
CHECK that the safety decals are not obstructed by the
openers. If the decals are covered up, replace in a location
that is clear to view.
REPLACE missing or unreadable decals. New decals are
available from your dealer.
To replace decals:
1. Remove the old decal. Clean the area where the new
decal will be affixed.
2. Remove the decal backing. Carefully affix the decal to
the air drill.
