Final answer:
The statement is false because the usage of the Rim Notch and Arrow on the bender shoe depends on the instructions for the bender and the type of bend required, not a fixed rule of using them once or twice respectively.
Step-by-step explanation:
The statement 'Always use the Rim Notch once and Arrow (twice) on the bender shoe when bending the Three Point Saddle Bend' is false. The Rim Notch and Arrow are references for different points of bends on a conduit when using a conduit bender. The process involves creating two bends at a certain distance from each other, with the middle bend (the saddle) being higher than the outer two.
However, the use of these references depends on the specific instructions for the bender and the type of bend required. Typically, for a Three Point Saddle Bend, the Rim Notch is used for the first bend, and the Arrow is used for aligning the conduit for subsequent bends, but the exact usage and number of times may vary. It's important to follow the manufacturer's instructions or standard bending formulas to determine the correct reference points and the number of times each should be used.
