INTRODUCTION
• Multiplier bar handles must be propped or supported
within the outer 1/4 of the handle length, or serious
under or over tightening will occur.
To convert pounds-foot (lb-ft) of torque to newton meters
(Nm), multiply the pounds-foot quantity by 1.3558.
To convert pounds-inch (lb-in) of torque to newton meters
(Nm), multiply the pounds-inch quantity by 0.11298.
