3. PLACEMENT OF SPRAY NOZZLE ASSEMBLY 4400AB FOR ALL BALERS WITHOUT A SHIELD
Conventional baler with gathering forks.

1. Mount the left-hand nozzle strap (it has an elbow fitting and a silver tip) so that it is approximately 80% across the width of the pick-up head. For example: if the head is 60” wide, locate the nozzle 48” from the right side of the head (60”x80”.)
2. Mount the right-hand nozzle strap (it has a tee fitting and a silver tip) so that it is approximately centered on the pickup head.
3. Place the two auxiliary nozzle straps in between the first two straps.
4. Bend the nozzle bar in so that the tip is pointed in toward the bottom of the gathering chamber and about 16” above the sheet metal base of the chamber. Twist the nozzle so the tip is tilted 45 degrees from the horizontal.
5. Attach hoses to nozzle straps. Clear hose to sliver tips. Green hose to green tip. Blue hose to blue tip. Secure with hose clamps.

4400AB FOR ALL BALERS WITH A SHIELD

You will need to use the existing shield and add elbows, stainless steel nozzle bodies, and the appropriate tips to complete the shield.

4. INSTALLATION OF PLUMBING

A. Intake
Use the 003-EL3412 on the bottom of the tank to route the 1/2″ line (002-9001) to the 003-A1212 fitting on the ball valve already attached to the pump plate. Attach hose clamps (003-9003) on both of the fittings.
B. Discharge for Conventional Square Balers
The three-1/4″ hose assembly will be used to attach the pumps to the spray shield. The pump order is from closest to the filter bowls 1,2 and 3. Pump 1 will attach to the main nozzles that have two tips – attach a clear hose to the silver tips. Pumps 2 and 3 will attach to the auxiliary nozzles, pump 2: green hose to green tip, pump 3: blue hose to blue tip.
C. Discharge for Three Tie Balers
The three-1/4″ hose assembly will be used to attach the pumps to the spray shield. The pump order is from closest to the filter bowls 1,2 and 3. Pump 1 will attach to the main nozzles that have two tips – attach a clear hose to the white tips. Pumps 2 and 3 will attach to the auxiliary nozzles, pump 2: a green hose to a green tip, and pump 3: a blue hose to a red tip.

5. INSTALLATION OF STAR WHEELS AND BALE RATE SENSORS
The pair of star wheels will need to mount on the bottom side as close to the front of the bale chute as possible and at least 3/8″ away from any metal. They will need to maintain a safe distance away from the twine.
The star wheels will require two holes to be drilled per block, when drilling make sure to keep the wheel square to the bale chamber. Any angle will cause stress on the wheel and will eventually cause the wheel to work itself out of the block. Some balers may require a notch cut on the bottom of the bale chamber to mount the star wheels as close to the front of the chamber as possible. Use the template in the back of the manual to aid in installation.
Use the supplied bolts and place the carriage head inside of the bale chamber followed by lock and nut. Next attach the star wheels to the bolts followed by a flat washer, lock washer, and nut. The right side star wheel will have the bale rate sensor bolted to the bottom of the block. The sensors need to be no more than 1/4 inch away from the star wheel itself. The cable will attach to the BMP at the bale rate sensor port.
Remove the four screws holding the plastic cover and attach one wire eye loop per star wheel through the grommet and tighten down with the nut attached to the swivel. Reinstall the cover and run the wires up to the pump plate. You will need to use zip ties to attach the wires so as to not interfere with normal baler use.

FOR THREE TIES BALERS

The pair of star wheels will need to mount on the top as close to the knotters as possible and at least 3/8″ away from any metal. They will need to maintain a safe distance away from the twine.
The star wheels will require two holes to be drilled per block, when drilling make sure to keep the wheel square to the bale chamber. Any angle will cause stress on the wheel and will eventually cause the wheel to work itself out of the block. A template can be found in the back of the manual to help with the placement of the star wheel.
Use the supplied 5/16” Allen head carriage bolts and place the carriage head inside of the bale chamber followed by lock and nut. Next, attach the star wheels to the bolts followed by the twine diverters 001-4644 and 001-4645. Finally secure the entire block using nuts, locks, and flat washers. The twine diverter with the bale rate sensors needs to be mounted on the right side of the baler when facing the back.
Remove the four screws holding the plastic cover and attach one wire eye loop per star wheel through the grommet and tighten down with the nut attached to the swivel. Reinstall the cover and run the wires up to the pump plate. You will need to use zip ties to attach the wires so as to not interfere with normal baler use.

   The machine will cycle all three of the pumps for 15 seconds. After the cycles are complete, the system will display a number next to each pump number.

2. If the system displays within the listed range.
   A. The system is operating correctly.
   If the system displays higher than the listed range, some common problems could be:
   A. Leak in line. Inspect lines thoroughly.
   B. Tip missing. Check for lost or broken tips on the spray shield.
   C. Tip wore. Replace tip.
   D. High tractor voltage.
   If the system displays lower than the listed range, some common problems could be:
   A. Make sure there is a preservative in the tank and the ball valve is in the open position.
   B. Air in lines. The pump will not prime. Check for leaks in lines or defective check valves.
   C. Pump is working, but not producing the desired output. The pump needs to be rebuilt.
   D. Main filter plugged. Check filter by tank and clean if necessary.
   E. Tip or tip screen plugged. Check both tip and tip screen and clean if necessary.
   F. Kink in hose. Straighten or replace the hose.
   G. Voltage from the tractor is low. Check the power cord with a multimeter for 12 volts at the baler-mounted processor. Clean connections on the battery. Dielectric grease connections at baler mounted processor and at hitch connection.
   H. Pump is defective. Rebuild the pump if the motor runs smoothly. Replace the pump if the motor is bad.

5. When done in this mode, press the MAIN MENU key.

COMMON QUESTIONS ABOUT THE 462

1. How do I turn the system on/off?****

– To turn the system ON simply press anywhere on the right side of the screen followed by pushing the press to start key. To turn the system OFF, return to the Main Menu screen and press the POWER OFF key.

2. How to get in the LBS/TON, MC%, and TONS/HR screens?****

– In the Main Menu press the SETUP MODE key. From this screen you can change your application rates and how much product is applied. See SETTING UP FOR INITIAL USE for a detailed explanation of this process

3. The unit is stuck in the Application Rate screen.****

– In the Application Rate screen, level 1 must be less than level 2, and level 2 must be less than level 3. For example, if level 1 is set at 16, level 2 must be set at 17 or higher, and level 3 must be set higher than level 2.

4. How does OVERRIDE work?****

– Override turns on all three pumps at full output. The pumps will remain at the full output until the operator turns these pumps off by pressing the OVERRIDE key again.

5. The flow meter reading is more or less than the programmed level set in the box.****

– Some variation in flow meter readings compared to the programmed set point is normal due to factory tolerances on the pump motors as well as varying tractor voltages inputted to the control box. The flow meter reading is an accurate measure of how much product is actually being applied. The set points then will need to be adjusted if you want to attain a different flow meter reading.

6. Why don’t all the pumps turn on even at higher application rates?****

– The selections of what pumps turn on when are automatically controlled by the control box’s flow rate look-up chart. Thus, not all the pumps turn on at once and the combination of what pumps turn on when is automatically controlled by the software. If you want to make sure all three pumps are working, go to the Diagnostics screen and run pump outputs. .

7. The moisture content displays “LO” or “HI” all the time.****

– When the moisture content display does not change frequently while baling, there is likely a faulty star wheel connection. One of the first places to check is inside the white star wheel block. Check to see if the electronic swivel is in the star wheel shaft and check to see that the star wheel shaft is not working out of the block. Also, check all star wheel wires and connectors to see if there is a continuity or grounding problem.

8. Should the battery connections be removed before jump-starting or charging a battery?****

– Yes. Anytime the tractor will have voltage going up rapidly the connections should be removed.

MAINTENANCE

1. Clean the tip strainers and main strainer every 10 hours of operation or more frequently if required.

2. Depending on the product being used, the system may need to be flushed with water at regular intervals (consult with the manufacturer of the chemical.) If Harvest Tec product is being used, flushing is not necessary.

3. Although the pump can run dry, extended operation of a dry pump will increase wear. Watch the preservative level in the tank.

4. Cover the automatic cab terminal on open station tractors if left outside.

5. Pump performance may start to decline after 400 hours (1500 acres on conventional balers) of use. Rebuilding pumps is a simple procedure if the motor is not damaged.
   Order pump rebuilding kit #007-4581 for the automatic unit.

6. If you are using bacterial inoculants, flush your system daily after every use.

7. Clean tank cap every 10 hours of operation.

BACKUP FUSE

The Model 462 is equipped with a backup system if your display is not functioning. This function is intended for use only as a temporary means of application and not as a way to apply preservatives over multiple fields or for a lengthy amount of time. The baler-mounted processor has a location for a backup fuse on the same side as the pump and flows meter harness that bypasses all other system inputs and applies preservatives using one pump (Pump Three) at a constant lbs/hour shown below. These values are based upon an input voltage of 13.5 DC. Insert at least a 10 amp up to 20 amp fuse (3 AG style) into the backup fuse port to activate the bypass. The system will not turn off or pause until the fuse is removed. The main fuse must also be functional for the backup fuse to work. | Tip Set| Output (lbs/hour)
---|---|---
462| High 180| High 180
 | Low 150| 150
