A2B SWITCH MOUNTING
Replace the existing switch at the boom tip with the new 608125 Radio A2B switch/transmitter, PATB3
with the spread spectrum technology.
Install the standoff to the boom head using 2 5/16x3/4” HEX bolts. The hole pattern for the standoff is
the same as that of conventional PAT A2B switches. In most cases the standoff can be mounted in
the same location as the conventional switch.
If not replacing an existing switch, the proper location would be one that allows the switch to rotate
freely without being obstructed by any part of the boom head. It should be mounted close to the dead
end mounting gusset. The switch should normally be mounted on the cab side of the crane.
For jib installations, locate the switch close to the jib head.
Remove the lynch pin from the standoff. Slide the A2B switch
onto the standoff. Replace the lynch pin into the standoff.
Install the weight and chain onto the A2B switch.
