Safety
Tractor Operation
General Operation
·Be aware of tractor safety procedure when working with an air drill.
·Review tractor manuals.
·Secure hitch pin with a retainer and lock drawbar in centre position.
·DO NOT RIDE!! No one should be allowed to ride on the air drill when in motion.
·No one but the operator in the driver’s compartment.
·Check behind when backing up.
·Reduce speed when working in hilly terrain.
·Never allow anyone within the immediate area when working.
·Stand clear when raising or lowering wings.

Safety
Transporting Operation
Maintenance
Hydraulics
Storage
·When transporting be aware of length, height, and width. Make turns carefully and be aware
of obstacles and overhead electrical lines.
·When transporting machine adhere to recommended safe speed. DO NOT EXCEED 20 MPH.
·Do not transport in poor visibility.
·When transporting, be sure transport lock pins are in locking position.
·The slow moving vehicle (SMV) emblem and safety reflectors must be secured on the machine
for safe transport
·Check that wings are firmly seated in transport wing stops and lock pins installed.
·Avoid soft surfaces. The additional wing weight on the centre wheels could cause the machine
to sink.
·Ensure safety chain is attached correctly.
·Shut the tractor off before making any adjustments or lubricating the machine.
·Block machine securely when making repairs.
·Wear close-fitted clothing.
·Do not modify the machine.
·Do not search for high pressure hydraulic leaks without hand and face protection. A tiny,
almost invisible leak can penetrate the skin, requiring immediate medical attention.
·Use cardboard or wood to detect leaks, never your hands!
·Double check that all is clear before operating hydraulics.
·Never remove hoses or hose ends with machine elevated. Ensure all pressure is off of lines to
be disassembled.
·Maintain proper hydraulic fluid levels.
·Keep all connectors clean for positive connections.
·Ensure all fittings and hoses are in good repair.
·Do not stand under wings.
·Store air drill away from areas of main activity.
·Level air drill and block up securely to relieve pressure on jack.
·Do not allow children to play on or around air drill.

Hitching
·Insure your hitch pin is in good condition.
·Position air drill clevis with tractor drawbar using hitch jack.
·After tractor to air drill connection is made, relieve pressure off the hitch jack.
·Pull jack pin. Swing hitch jack parallel to hitch pole and re-pin jack.
·Connect safety chain.
Operation
Hydraulics
·Ensure quick couplers are dirt free.
·Dirt in the hydraulic system could damage o-rings, causing leakage, pressure loss,
and total system failure!
·Inspect all fittings and hoses for leaks, bends, or kinks.
·Connect the four hydraulic lines. Be sure the wing and depth hoses are matched and
connected to the correct valve.

10 July 2005
Operation
Initial Operation
·Make sure that the wheel bolts on the main center frame and the wings are tightened after the
first 5 km and then after the next 10 km and the next 20 km during the first few hours of use or
transporting. After the initial use, check wheel bolts every 40 hours of operation.
Leveling
·Initial leveling should be done on a flat, level surface, similar to that of a concrete floor.
·Level frame front to back using the series of holes that
are on the hitch.
·Level the wings using the 1” threaded rod that is located
on either end of the frame attached to the wing wheel
module.
·Be sure that the final adjustment is made under field working conditions. When set properly
the disc openers will be working at the same depth from front to back and from side to side.

July 2005 11
Operation
·On 3-plex machines the height of the frame is
controlled by a series of donuts located on the end lift
cylinder. Simply add or remove the donuts to set the
height.
·On 5-plex machines the height of the frame is
controlled by a series of donuts located on the lift
cylinders on the center frame. Simply add or remove
the donuts to set the height, making sure both
cylinders are set the same. This will prevent the rear
rockshaft from twisting due to one cylinder traveling
farther than the other.
Height Adjustment
Setting Openers
·By adjusting the main tension spring, you will increase the penetrating force of the opener. It is
best if you can run the 36 series opener in a horizontal position, giving more uniform packing
pressure. This is accomplished by lowering the frame to the required position.
·Packer pressure is set by adjusting the top nut of the packer.
·Travel speed will affect disc penetration and varies upon soil condition, type, and depth of
seeding.
·In our experience it is best to tighten the springs so about 1/3 of spring bolt threads are used
when unit is off the ground. If main tension spring is too tight, packer will bottom before
horizontal position is reached, holding the blades out of the ground.

12 July 2005
Operation
Transporting
·Use safety locks on main frame and wings
when transporting!
·Do not walk under wings when raised or lowered.
Ensure cylinders are completely filled with
hydraulic fluid. Entrapped air or hydraulic system
failure could cause wings to fall rapidly causing
serious injury or death.
·Never exceed 20 mph (32 kph) in transport.

July 2005 13
Maintenance
Use safety lock pins when doing any maintenance on the machine!
Daily or every 10 hours
·Grease rear rockshaft.
Weekly or every 50 hours
·Check for and tighten loose wheel bolts.
·Check tire pressure. 16.5 x 16.1 tires should be maintained at a pressure of 48 psi.
·Inspect all hinge pins to ensure they are in place.
·Inspect hydraulic system for leaks, damaged hoses, and loose fittings.
Annually or every 200 hours
·Grease main wheel hubs.
·Check for any cracked or broken welds.
·Check for and tighten loose wheel bolts.
·Check tire pressure. 16.5 x 16.1 tires should be maintained at a pressure of 48 psi.
·Inspect all hinge pins to ensure they are in place.
·Inspect hydraulic system for leaks, damaged hoses, and loose fittings.
Frame
Openers
Annually or every 200 hours
·Ensure that all spindle bolts are tight.
·Check for any other loose hardware.
·Check inner blade clearance and remove shims if required. Discs should just touch. Use anti-
seize on spinde when replacing so that it is easy to remove the next time.
·Adjust mud scraper clearance.
·Adjust seed deflector clearance.
·Oil blades after the season if desired to keep them from rusting.
·For longest blade life, reverse rear blade with the front blade after the end of the season. It is
well worth the time!

Options
Mud Scraper
Residue Manager
·A mud scraper attachment is available for use in sticky soil conditions.
·A residue manager may be attached to the opener to help reduce hair-pinning in heavy residue.
Blades
·Larger 17” blades are available. They are generally used on openers behind the tractor tires.
