Item #4. I do not know why you did not receive the owner’s manual information. The information
below is the exact text of what is printed in the Owner’s Manual for the machine in which the
transmitter is installed. As one can see, there is no user interaction. The transmitter is installed
and it operates. It is only being used as a safety device which should be used only on very rare
occasions. The entire manual is not printed below. Since the actual manual (hundreds of pages)
is for a very large and complex machine, only the pertinent section is excerpted for your needs.
OPTIONAL SPRAY ARM BREAK AWAY
The optional Spray Arm Break Away system allows the UltraSonic 2001-Overhead machine to
shut down in the event that a customer drives their vehicle into the spray arm when it is in front of
or behind the vehicle. To prevent damage if this occurs, a shear bolt in the spray arm mechanism
breaks to prevent damage to the vehicle or the wash equipment. When this happens a tilt switch
activates a small radio transmitter that is mounted on the spray arm. A radio receiver mounted in
the machine gantry terminal box signals the machine controls causing the machine to
immediately shut down and no longer operate. The machine is in a no-operation condition and
can no longer arm for a wash. It remains in this state until it is reset. The machine's 2-digit
display will show an 08 diagnostic code and a 4-digit diagnostic code 8608 will be recorded. The
bay switch buzzer will sound for 5 seconds and the machine movement beeper alarm will sound
continuously.
RETURNING THE MACHINE TO OPERATION
STEP 1: Inspect the spray arm for safe continued operation.
STEP 2: Remove the white screw caps from the heads of the four (4) screws that secure the
white plastic cover to the horizontal spray arm. Remove the plastic cover and the mounting
clamp with transmitter off of the spray arm by removing the four (4) screws. Note: The
transmitter assembly will still be connected to the tilt switch and should be kept near enough to
the spray arm to prevent interfering with this connection.
STEP 3: Remove and save the existing flat 3/8” (10 mm) washer and nut from the broken shear
bolt. Install the new shear bolt into the spray arm where the broken bolt was removed.
CAUTION! USE ONLY THE SHEAR BOLT RECOMMENDED FOR THIS
EQUIPMENT. USE OF ANOTHER BOLT WILL NOT ALLOW THE SPRAY ARM
BREAK AWAY TO OPERATE PROPERLY AND MAY CASUE DAMAGE TO THE
MACHINE OR TO VEHICLES. WHEN ORDERING REPLACEMENT PARTS,
CONTACT THE RYKO PARTS DEPARTMENT IF UNSURE OF THE PROPER PART
TO ORDER,.
Install the flat 3/8” (10 mm) stainless steel washer under the nut when replacing a broken shear
bolt. Do not install the washer under the head of the shear bolt. Draw the two stainless steel
blocks (where the bolt goes through) of the break-away assembly together by tightening the nut.
After drawing the two halves together, loosen the nut until the washer under the nut can spin
freely (approximately 1/4 turn).
STEP 4: Reassemble the white plastic cover and the mounting clamp with transmitter onto the
horizontal spray arm using the four (4) screws previously removed. Reattach the four (4) screw
caps previously removed. Refer to the Top Spray Arch Cover Installation drawing in the
Installation Manual.

WARNING! NEVER RESET THE MACHINE TO ALLOW FURTHER OPERATION
WITHOUT FIRST REPLACING THE SHEAR BOLT AND INSPECTING THE SPRAY
ARM AND MACHINE FOR CONTINUED SAFE OPERATION. FAILING TO DO SO
MAY RESULT IN DAMAGE TO THE MACHINE OR A VEHICLE. IF IN DOUBT,
CONTACT RYKO CUSTOMER SERVICE FOR ASSISTANCE.
STEP 5: The machine will not operate again until it is reset via the Test Function FC “Arm Break
Away Reset”. Refer to the Test Function Information document included in the Owner’s Manual
to reset the machine movement beeper alarm and allow the machine to operate normally.
