Important: For Multi Pro Machines Model Year 2023 and before, you must purchase and install the boom cradle kit 161-4170.
Note: Determine the left and right sides of the machine from the normal operating position.
Clean the exterior of the machine and sprayer; refer to the Operator’s Manual for your machine.
Move the machine to a level surface, shut off the engine, set the parking brake, and remove the key.
If you leave the key in the ignition switch, someone could accidently start the engine and seriously injure you or other bystanders.
Remove the key from the ignition switch before you install the kit.
Disconnect the negative-battery cable from the battery; refer to the Operator’s Manual for your machine.
Important: Operating the spray system with the boom-hinge springs under the incorrect compression could damage the boom assembly. Measure the springs and use the jam nut to compress the springs to 36 mm (1.40 inches), if necessary.
Use another person or lifting equipment to support the boom while adjusting the spring height of the boom hinge.
Extend the outer booms to the spray position (horizontal).
Support the booms while you are adjusting the spring height.
At the pivot bracket and hinge for the outer boom, adjust the jam nut for the upper spring until the compressed spring height measures 36 mm (1.40 inches).
Adjust the jam nut for the lower spring until the compressed spring height measures 36 mm (1.40 inches).
Repeat steps 3 and 4 for the upper and lower springs at the other outer boom.
At the boom hinge, measure the compression of the upper and lower springs while the booms are in the extended position (Figure 2).
Compress all springs until they measure 36 mm (1.40 inches).
Use the jam nut to compress any spring that measures greater than 36 mm (1.40 inches).
Note: You will need 2 wooden blocks about 10 cm (4 inches) in height for this procedure.
The booms are set at the factory to travel downward no farther than the horizontal position. To enable the ultrasonic boom kit to maintain a consistent distance between the nozzles and the ground when the ground slopes downward from the machine, you must adjust the boom support system to allow the booms to travel below the horizontal position to maintain a constant nozzle-to-ground distance.
Raise the booms and have them rest in the transport cradle.
At the pivot brackets of the outer-boom sections, remove the hairpin and clevis pin that secures the rod end for the lift cylinder to the pivot bracket (Figure 3).
Note: There should be no more than 16 mm (5/8 inch) of exposed thread on the eyelet to prevent the engaged threads from stripping and the rod from pulling away.
Carefully lower the outer-boom sections onto wooden blocks about 10 cm (4 inches) high as shown in Figure 4.
Start the machine and fully extend the lift cylinders.
Loosen the jam nuts at the rod ends for each lift cylinder (Figure 3).
Adjust the rod end for the lift cylinders end until the hole in the rod ends align with the holes in the pivot brackets for the boom sections (Figure 3).
At each pivot bracket, secure the rod end to the bracket with the clevis pin that you removed in step 2.
Secure the cotter pins to the pivot brackets with the hairpin cotters (Figure 3) that you removed in step 2.
Tighten the jam nut at each rod until the nuts are snug (Figure 3).

Once you initiate the controller processor for calibration, you will have 20-seconds to calibrate the sensors on the booms. The distance you set between the sensor on each boom and the ground after the 20-second calibration period is the boom height setting in automatic mode until the next time you calibrate the sensor.
Note: For uncovered booms: The default height setting is 51 cm (20 inches) from the nozzle to the ground. If, after setting a boom to a height different from that of the factory default setting, you wish to restore the calibration to the factory-default setting, calibrate the boom with the boom in the cradle. For covered booms: The default height setting of 51 cm (20 inches) is for uncovered booms only. You must calibrate the sensors on covered booms.

While pressing and holding both the left boom-lift control switch to the LOWER position and the right boom-lift control switch to the RAISE position, turn the ignition key and start the machine.
Release the boom switches.
Note: The indicator light on the sonic-boom switch will flash rapidly, indicating that the sonic boom system is in calibration mode. You now have 20 seconds to use the Raise and Lower boom switches to set the desired distance between the booms to the ground. After the 20 seconds, the indicator light flashes slowly.
Raise and lower the outer-boom sections using the boom-lift control switches to adjust the height of each boom until you achieve the desired distance between the tip of the boom and the ground.
Important: Raise the booms one at a time. This prevents the booms contacting each other preventing any possible damage to the sensors mounted on the booms.
The sonic-boom switch is located on the dashboard and has 2 settings: automatic mode and manual mode.
The automatic mode enables the machine to control the outer boom position, thereby continually positioning the boom-tip height at the desired distance from the ground.
The manual mode turns off the automatic boom-position adjustment, and allows you to change the booms boom height manually.
Note: The sonic boom indicator light (Figure 31, Figure 32, or Figure 33) illuminates on the sonic-boom switch, and indicates the status of the sonic boom system as follows:
On continuously: The sonic boom system is active and operating normally.
Flashing quickly: The system is in calibration mode, which lasts for 20 seconds.
Flashing slowly: There is either an error in the system or you have overridden the automatic mode by operating a boom or both booms manually while the system is in automatic mode.
Note: If there is a fault in the sonic boom system (e.g., there is no signal coming from a sensor), the boom raises for a few seconds and then stops, and the light on the boom switch (located on the dashboard) flashes slowly—indicating that control of a boom or both booms has stopped.

Note: The light on the sonic-boom switch illuminates.
Use the boom-lift control switch (Figure 31, Figure 32, or Figure 33) to lower boom to the desired distance from the ground.
To override the automatic mode boom position, perform the following:
Note: You can temporarily override the automatic operation of the booms using the boom-lift control switches (Figure 31, Figure 32, or Figure 33) to raise or lower a boom or both booms.
Lower the boom(s) manually, by pressing and holding the boom-lift control switch(s) to the LOWER position until the outer boom(s) lowers to the desired height.
Raise the boom(s) manually by pressing and holding the boom-lift control switch(s) to the RAISE position until the outer boom(s) raises to the desired height.
Note: If you adjust only 1 boom, the other boom continues to function in the automatic mode.
To resume the automatic mode, momentarily press the boom-lift control switch(s) to the LOWER position (Figure 31, Figure 32, or Figure 33) to allow the sonic-boom controller to position the boom-tip height at the desired distance from the ground.
Important: When operating the machine over especially uneven terrain, reduce the ground speed to prevent the booms from striking the ground.
Clean the sensors periodically with a damp cloth. If a sensor is damaged or excessively dirty, replace it.
Important: Do not spray pressurized water at or on the sensors. Household pressure is recommended to minimize direct exposure of water to the sensors for cleaning.
