Use extreme caution when moving the auger, especially near power lines. It is not necessary to come into direct contact with an overhead power line for electrocution to occur. Serious injury or death will result. WARNING! Keep arms, hands and legs away from auger intake. Wear appropriate fitting clothing when working in the vicinity of an auger.
4.3.1 Positioning the Auger 1. Ensure your tractor circuit is engaged in the correct direction prior to engaging the auger diverter valve. NOTE: If remote does not operate properly use manual levers provided as backup control. NOTE: Ensure that the area in the vicinity of auger operation is free of obstructions and that all bystanders, especially children, are kept at a safe distance before positioning or operating the auger. 2.
4.3.2 Operating the Auger 1. Ensure that all screens and shrouds are in place and that the cleanout gate, on the bottom of each meter, is closed. 2. Activate tractor hydraulic circuit #4, and direct the diverter valve up to the auger circuit. 3. The handle on the auger tube is the control to operate the auger flighting in a forward or reverse direction. 4. Whether filling or unloading the Aircart, the auger performs at its highest capacity when product is falling directly into the flighting. 4.3.
4.3.4 Auger Transport Position NOTE: Fill auger should always be secured for transport, no matter how short the distance. Clean out auger prior to transport or storage. 1. Position the auger so that the tube is resting on the locking mechanism at the back of the aircart. In TBH configurations only, the hopper can be rotated down for transport. 2. The locking mechanism must be used to secure auger when transporting at all times. 3. Be sure to secure locking mechanism by replacing pin. 4.
4.4 Fill Conveyor NOTE: Aircart lids must be closed and sealed for accurate metering. If metering is erratic, ensure tank lids are closed properly. DANGER! Use extreme caution when moving the conveyor, especially near power lines. It is not necessary to come into direct contact with an overhead power line for electrocution to occur. Serious injury or death will result WARNING! Keep arms, hands and legs away from conveyor intake. Wear appropriate fitting clothing when working in the vicinity of a conveyor.
4.4.1 Positioning The Conveyor 1. Ensure the tractor circuit is engaged in the correct direction prior to engaging the conveyor diverter valve. If circuit is already engaged, direct the fan diverter valve to the conveyor position from the fan setting. Use the remote provided to move the conveyor in and out of transport. 2. Remove pin from outer arm locking mechanism and unlatch.
4.4.2 Operating the Conveyor 1. Ensure that all screens and shrouds are in place and that cleanout gate on each meter is closed. 2. Activate tractor hydraulic circuit #4, and pull the diverter valve up to the auger circuit. NOTE: Whether filling or unloading the Aircart, the auger performs at its highest capacity when product is falling directly into the flighting. 3. Use either of the buttons located at the top and bottom of the conveyor to start and stop the conveyor. 4.4.
4.4.4 Conveyor Transport Position 1. Latch down the conveyor hopper then fold it up on top of the conveyor tube. Be sure to secure it with the tie down strap supplied. 2. Arrange the conveyor so that the upper rest is positioned on the conveyor saddle at the front of the aircart. 3. Raise the locking mechanism at the rear of the aircart. The handle can be unlocked and swung towards the aircart for transport 4.
4.5 Bag Lift If equipped, the optional bag lift can be used for transporting bagged agricultural product from the ground to the top of the air cart. The bag lift has a maximum capacity of 500 lbs. or ten bags of canola (50 lb. bags). The bag lift runs off the same hydraulic circuit as the auger or conveyor. To operate the bag lift the diverter valve must be switched to the auger or conveyor setting. After loading the bag lift use the valve located at the front of the cart to operate the hydraulic cylinder.
4.6 Metering Roller The metering roller is provided in each compartment. The roller is divided into replaceable sections which can be replaced if damage occurs. If there is a damaged section the product gate above the roller can be closed to facilitate changing without emptying the tank. The meter roller can then be removed and repaired, quickly, without product spillage. Some meters have two colored roller sections. The red sections have less displacement than the black sections.

This tractor lever is locked in full pressure position while seeding.
4.8 Seed Hawk® Pressurized Metering System With the Seed Hawk® pressurized metering system product can be diverted to either air stream. This gives the Aircart ultimate flexibility by allowing the option of diverting any product to either the seed knife or the fertilizer knife. To change the air stream that a meter will deliver product to, adjust the diverter valve on the side of the meter body. NOTE: This meter is only designed to send product into one air stream at a time.
4.9 Checking Air & Product Flow The test procedure outlined below serves as a guideline for ensuring proper fan speed for effective delivery of product: 1. Remove hose(s) from an outside opener and temporarily attach to the frame of the seeder with the hose looping no more than 12 in. (300mm) below the frame. 2. Begin seeding at normal field speed and observe distance product discharges from hose(s) attached to the frame. All product should discharge within a range of 12-24 in. (300-600mm). 3.
