Calibrate the sonic booms.
Note: T he Sonic Boom Kit requires electric boom lift actuators to automatically raise and lo w er the
booms . Most mac hines ha v e had electric boom actuators installed or are being installed in concer t with
this Sonic Boom Kit. T he setup procedures that follo w w ere dev eloped for these situations . If y ou do
not ha v e electronic boom lift actuators installed or a v ailable to be installed, contact y our A uthorized T oro
Dealer to obtain the cor rect par ts to modify y our spra yer to be compatible with the Sonic Boom Kit. T he
necessar y par ts are: Electronic Boom Lift Actuators (2), Fuses (2), and Switc hes (2).
Note: Deter mine the left and right sides of the mac hine from the nor mal operating position.

Calibrating the Sonic Booms
No Parts Required
Procedure
1. P ark the spra yer in an open, lev el turf area that
is free of trees , buildings , v ehicles , debris , and
underg round utilities and plumbing .
2. Set the Sonic Boom switc h to the man ual
position.

indicating calibration mode .
6. R elease the boom switc h.
7. Use the boom switc hes to adjust the booms
if necessar y so that they are parallel to the
g round.
Y ou will ha v e 20 seconds to adjust the booms .
At the end of 20 seconds the light stops
flashing and the Sonic Boom calibration is
complete .

Operation
Using the Controls
Sonic Boom s witch —this switc h has 3 settings:
A utomatic , Off , and Man ual ( Figure 22 ), as
follo ws:
•A utomatic—enables the automatic mo v ement
of the booms . W hen in automatic mode the
booms adjust so that the tips of the booms
remain the same distance from the g round.
Y ou can temporarily o v er ride the automatic
operation of the booms using the boom
switc hes to raise or lo w er one or both booms .
If y ou raise a boom it will remain raised until
y ou lo w er it halfw a y with the boom switc h; at
whic h point the automatic operation of the
boom contin ues . If y ou adjust only one boom,
the other contin ues to function automatically .
