HELPFUL INFORMATION ON TORQUING

Always follow manufacturer's specifications whenever available.
Any assembly held together by a number of fasteners should be tightened down a little at a time,
going to each fastener in turn, until specified torque has been reached.
A good practice to follow is to torque in the following manner:
>
Apply ¾ of the specified torque to each fastener.
>
Reset the wrench and tighten each fastener to the specified torque.
>
After tightening all the fasteners, repeat the final tightening to make certain all fasteners are at
the specified torque.
Never use a torque wrench on a nut already tightened with a standard wrench or socket. For
accurate torque, the final turn of the nut must be done with a torque wrench.
Your torque wrench is a precision measuring instrument. We recommend servicing only by
authorized Proto service personnel.

Your Proto
