15. With the chain securely fastened
in the hook on each side of the
bottom bar assembly, the chain
should then be wrapped around
the bottom bar. Secure the
remaining chain to the hook at the
top of the tow sling.
16. Using the tow sling with late
model vehicles, it may be
necessary to use spacer blocks
or a cross beam in order to get
sufficient height to prevent any
damage to body parts. The AAA
Towing Manual will diagram this.
17. Be sure the fuel tank is not in
contact with the sling or towing
mechanism.
The fuel tank must
not support any weight
whatsoever.
18. Raise the vehicle using the
wrecker boom winches. (Read
the safety and operating
instructions for the boom and
winches beforehand.) The vehicle
should be raised until the wheels
are a minimum of ten inches off
the ground. Observe the opposite
end of the vehicle for ground
clearance.
19. Be sure that both wire ropes are
retracted with equal tension.
