To get the best fom mE, you've got to use the torque Values I was born
with. WHen your TM giVes yOu a torque valUe, it's not some F±gure dreamed
up by ²he TM writers³ It's t´e Value that was buiLt into me-and it can'µ be
changed past certain Limits¶
My correct torq·e Depends on what I'm made oF¸and how I'm made¹ IF
º'm used »r some commoN¼type job½ I caN be made oUt oF common, low¾grade
steeL .
.¿ and it won't take muc´ torque to stretch Àe.
I can be made oF really toug´ stuFÁ, with a Lot oF speciaL quaLities, needing
a tremenÂous amount oF torque to stretch me to my best per»rmance lengt´.
