GENERAL INSTRUCTIONS
Secure longitudinal chains to vehicle. Pull chains as tight as possible by hand and attach hook into an
appropriate link in the chain. All chain tie-downs must be made taut by tightening the turnbuckles.
Tie-downs in the inboard channels are to be in line across the car and tie-downs in the outboard channels are to
be in line in the same manner. The angle of the tie-downs must be as close to 45° as possible.
Gear shift levers are to be placed in a neutral position.
Turnbuckles not equipped with self-locking devices must be wired or locked to prevent loosening.
See General Rules 4, 5,14, 15, 19-A, 19-B and 19-C for further details.
