SIZING THE VACUUM HOSE AND ELECTRICAL CONNECTIONS ACROSS TOW BAR
a. With the toad vehicle connected to the tow bar, fi nd the minimum length of the breakaway lanyard by measuring from the anchor point on the
RV (as close to center as possible) to the breakaway switch. Record this measurement as X=
b. Find the maximum length of the breakaway lanyard by disconnecting the tow bar and leaving the tow cables connected. Slowly back up the toad
until the cables capture it. Apply the parking brake, and turn off the engine. Make the same measurement as in step a. Record this measurement
as Y=
c. To fi nd the length of the lanyard to be used take the measurements (X) and (Y), add them together, and divide by 2, (X+Y)/2=Lanyard Length
NOTE THE LANYARD LENGTH MUST BE LONG ENOUGH TO PERMIT TURNING WITHOUT PULLING THE PIN WHEN TOWING. THE ABOVE
SIZING PROCEDURE ALLOWS THE BREAK AWAY PIN TO PULL AND APPLY Vac Brake™ TO HELP CONTROL THE TOAD VEHICLE WHEN IT
FALLS BACK ON THE SAFETY CABLES OR CHAINS.
